NEW QUESTION # 35
You need to configure wireless access for several classes of loT devices, some of which operate only with 802
11b. Each class must have a unique PSK and will require a different security policy applied as a role There will be 15-20 different classes of devices and performance should be optimized Which option fulfills these requirements''

• A. Individual SSIDs with unique PSK for each loT class, using 5GHz and 6 GHz bands
• B. Single SSID with MPSK for each loT class using 5 GHz and 6 GHz bands
• C. Individual SSIDs with unique PSK for each loT class, using 2.4GHZ and 5GHz band
• D. Single SSID with MPSK for each loT class using 2.4GHz and 5 GHz bands

Answer: C

Explanation:
Explanation
The option that fulfills the requirements is to create individual SSIDs with unique PSK for each loT class, using 2.4 GHz and 5 GHz band. This option provides the following benefits:
Each loT class has a unique PSK that can be used to apply a different security policy as a role. This enhances the security and flexibility of the WLAN network.
Individual SSIDs allow for better isolation and management of different loT classes. This improves the performance and scalability of the WLAN network.
Using both 2.4 GHz and 5 GHz bands allows for backward compatibility with loT devices that operate only with 802.11b, which uses the 2.4 GHz band . It also allows for higher throughput and less interference for loT devices that support 802.11a, 802.11g, 802.11n, or 802.11ac, which use the 5 GHz band2.
The other options do not fulfill the requirements because:
Single SSID with MPSK for each loT class using 5 GHz and 6 GHz bands: This option does not support loT devices that operate only with 802.11b, which uses the 2.4 GHz band . It also does not optimize the performance of the WLAN network, as a single SSID may cause co-channel interference and congestion among different loT classes.
Single SSID with MPSK for each loT class using 2.4 GHz and 5 GHz bands: This option does not optimize the performance of the WLAN network, as a single SSID may cause co-channel interference and congestion among different loT classes.
Individual SSIDs with unique PSK for each loT class, using 5 GHz and 6 GHz bands: This option does not support loT devices that operate only with 802.11b, which uses the 2.4 GHz band1.

NEW QUESTION # 36
Review the configuration below.

Why would you configure OSPF to use the IP address 10.1.200.1 as the router ID?

• A. The loopback interface state is dependent on the management interface state and reduces routing updates.
• B. The IP address associated with the loopback interface is non-routable and prevents loops
• C. The IP address associated with the loopback interface is routable and prevents loops
• D. The loopback interface state Is independent of any physical interface and reduces routing updates.

Answer: D

Explanation:
Explanation
The reason why you would configure OSPF Open Shortest Path First (OSPF) is a link-state routing protocol that dynamically calculates the best routes for data transmission within an IP network. OSPF uses a hierarchical structure that divides a network into areas and assigns each router an identifier called router ID (RID). OSPF uses hello packets to discover neighbors and exchange routing information. OSPF uses Dijkstra's algorithm to compute the shortest path tree (SPT) based on link costs and build a routing table based on SPT. OSPF supports multiple equal-cost paths, load balancing, authentication, and various network types such as broadcast, point-to-point, point-to-multipoint, non-broadcast multi-access (NBMA), etc. OSPF is defined in RFC 2328 for IPv4 and RFC 5340 for IPv6. to use the IP address IP address Internet Protocol (IP) address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing. There are two versions of IP addresses: IPv4 and IPv6. IPv4 addresses are 32 bits long and written in dotted-decimal notation, such as 192.168.1.1. IPv6 addresses are 128 bits long and written in hexadecimal notation, such as 2001:db8::1. IP addresses can be either static (fixed) or dynamic (assigned by a DHCP server). 10.1.200.1 as the router ID Router ID (RID) Router ID (RID) is a unique identifier assigned to each router in a routing domain or protocol. RIDs are used by routing protocols such as OSPF, IS-IS, EIGRP, BGP, etc., to identify neighbors, exchange routing information, elect designated routers (DRs), etc.
RIDs are usually derived from one of the IP addresses configured on the router's interfaces or loopbacks, or manually specified by network administrators. RIDs must be unique within a routing domain or protocol instance. is that the loopback interface state Loopback interface Loopback interface is a virtual interface on a router that does not correspond to any physical port or connection. Loopback interfaces are used for various purposes such as testing network connectivity, providing stable router IDs for routing protocols, providing management access to routers, etc. Loopback interfaces have some advantages over physical interfaces such as being always up unless administratively shut down, being independent of any hardware failures or link failures, being able to assign any IP address regardless of subnetting constraints, etc. Loopback interfaces are usually numbered from zero (e.g., loopback0) upwards on routers. Loopback interfaces can also be created on PCs or servers for testing or configuration purposes using special IP addresses reserved for loopback testing (e.g., 127.x.x.x for IPv4 or ::1 for IPv6). Loopback interfaces are also known as virtual interfaces or dummy interfaces . Loopback interface state Loopback interface state refers to whether a loopback interface is up or down on a router . A loopback interface state can be either administratively controlled (by using commands such as no shutdown or shutdown ) or automatically determined by routing protocols (by using commands such as passive-interface or ip ospf network point-to-point ). A loopback interface state affects how routing protocols use the IP address assigned to the loopback interface for neighbor discovery , router ID selection , route advertisement , etc . A loopback interface state can also affect how other devices can access or ping the loopback interface . A loopback interface state can be checked by using commands such as show ip interfacebrief or show ip ospf neighbor . is independent of any physical interface and reduces routing updates.
The loopback interface state is independent of any physical interface because it does not depend on any hardware or link status. This means that the loopback interface state will always be up unless it is manually shut down by an administrator. This also means that the loopback interface state will not change due to any physical failures or link failures that may affect other interfaces on the router.
The loopback interface state reduces routing updates because it provides a stable router ID for OSPF that does not change due to any physical failures or link failures that may affect other interfaces on the router. This means that OSPF will not have to re-elect DRs Designated Routers (DRs) Designated Routers (DRs) are routers that are elected by OSPF routers in a broadcast or non-broadcast multi-access (NBMA) network to act as leaders and coordinators of OSPF operations in that network. DRs are responsible for generating link-state advertisements (LSAs) for the entire network segment, maintaining adjacencies with all other routers in the segment, and exchanging routing information with other DRs in different segments through backup designated routers (BDRs). DRs are elected based on their router priority values and router IDs . The highest priority router becomes the DR and the second highest priority router becomes the BDR . If there is a tie in priority values , then the highest router ID wins . DRs can be manually configured by setting the router priority value to 0 (which means ineligible) or 255 (which means always eligible) on specific interfaces . DRs can also be influenced by using commands such as ip ospf priority , ip ospf dr-delay , ip ospf network point-to-multipoint , etc . DRs can be verified by using commands such as show ip ospf neighbor , show ip ospf interface , show ip ospf database , etc . , recalculate SPT Shortest Path Tree (SPT) Shortest Path Tree (SPT) is a data structure that represents the shortest paths from a source node to all other nodes in a graph or network . SPT is used by link-state routing protocols such as OSPF and IS-IS to compute optimal routes based on link costs . SPT is built using Dijkstra's algorithm , which starts from the source node and iteratively adds nodes with the lowest cost paths to the tree until all nodes are included . SPT can be represented by a set of pointers from each node to its parent node in the tree , or by a set of next-hop addresses from each node to its destination node in the network . SPT can be updated by adding or removing nodes or links , or by changing link costs . SPT can be verified by using commands such as show ip route , show ip ospf database , show clns route , show clns database , etc . , or send LSAs Link-State Advertisements (LSAs) Link-State Advertisements (LSAs) are packets that contain information about the state and cost of links in a network segment . LSAs are generated and flooded by link-state routing protocols such as OSPF and IS-IS to exchange routing information with other routers in the same area or level . LSAs are used to build link-state databases (LSDBs) on each router , which store the complete topology of the network segment . LSAs are also used to compute shortest path trees (SPTs) on each router , which determine the optimal routes to all destinations in the network . LSAs have different types depending on their origin and scope , such as router LSAs , network LSAs , summary LSAs , external LSAs , etc . LSAs have different formats depending ontheir type and protocol version , but they usually contain fields such as LSA header , LSA type , LSA length , LSA age , LSA sequence number , LSA checksum , LSA body , etc . LSAs can be verified by using commands such as show ip ospf database , show clns database , debug ip ospf hello , debug clns hello , etc . due to changes in router IDs.
The other options are not reasons because:
The IP address associated with the loopback interface is non-routable and prevents loops: This option is false because the IP address associated with the loopback interface is routable and does not prevent loops. The IP address associated with the loopback interface can be any valid IP address that belongs to an existing subnet or a new subnet created specifically for loopbacks. The IP address associated with the loopback interface does not prevent loops because loops are caused by misconfigurations or failures in routing protocols or devices, not by IP addresses.
The loopback interface state is dependent on the management interface state and reduces routing updates: This option is false because the loopback interface state is independent of any physical interface state, including the management interface state Management interface Management interface is an interface on a device that provides access to management functions such as configuration, monitoring, troubleshooting, etc . Management interfaces can be physical ports such as console ports, Ethernet ports, USB ports, etc., or virtual ports such as Telnet sessions, SSH sessions, web sessions, etc . Management interfaces can use different protocols such as CLI Command-Line Interface (CLI) Command-Line Interface (CLI) is an interactive text-based user interface that allows users to communicate with devices using commands typed on a keyboard . CLI is one of the methods for accessing management functions on devices such as routers, switches, firewalls, servers, etc . CLI can use different protocols such as console port serial communication protocol Serial communication protocol Serial communication protocol is a method of transmitting data between devices using serial ports and cables . Serial communication protocol uses binary signals that represent bits (0s and 1s) and sends them one after another over a single wire . Serial communication protocol has advantages such as simplicity, low cost, long

NEW QUESTION # 39
You put in a few show commands on switches EDGE1 and CORE1 to attempt to gather information to troubleshoot the issue Use the show command output images to determine the reason for the EDGE1 uplink being down

• A. Spanning-Tree block state is preventing the Core uplink from having connectivity to the edge
• B. The physical interfaces are not members of the correct LAG.
• C. The Core is connected to the incorrect physical interlaces
• D. LACP is not configured on the Core uplink

Answer: D

Explanation:
Explanation
LACP is a protocol that allows multiple physical links to be aggregated into a single logical link for increased bandwidth and redundancy. LACP must be configured on both ends of the link for it to work properly. In this case, EDGE1 has LACP configured on its uplink port-channel 1, but CORE1 does not have LACP configured on its corresponding port-channel 1. This causes a mismatch and prevents the link from coming up.

Each layer has its own function and is responsible for well-defined tasks. User data passes sequentially from the highest layer down through the lower layers until the device transmits it externally. The lowest layer, the physical layer, converts the data into bits that can be sent over a physical medium. The second layer, the data link layer, organizes the bits into frames that can be transmitted over a link between two nodes. The third layer, the network layer, organizes the frames into packets that can be routed across a network of nodes. The fourth layer, the transport layer, organizes the packets into segments that can provide reliable and error-free communication between two end points12. References: 1

NEW QUESTION # 41
What does WPA3-Personal use as the source to generate a different Pairwise Master Key (PMK) each time a station connects to the wireless network?

• A. Simultaneous Authentication of Equals (SAE)
• B. Opportunistic Wireless Encryption (OWE)
• C. Key Encryption Key (KEK)
• D. Session-specific information (MACs and nonces)

Answer: D

Explanation:
Explanation
The source that WPA3-Personal uses to generate a different Pairwise Master Key (PMK) each time a station connects to the wireless network is session-specific information (MACs and nonces). WPA3-Personal uses Simultaneous Authentication of Equals (SAE) to replace PSK authentication in WPA2-Personal. SAE is a secure key establishment protocol that uses a Diffie-Hellman key exchange to derive a shared secret between two parties without revealing it to an eavesdropper. SAE involves the following steps:
The station and the access point exchange Commit messages that contain their MAC addresses and random numbers called nonces.
The station and the access point use their own passwords and the received MAC addresses and nonces to calculate a shared secret called SAE Password Element (PE).
The station and the access point use their own PE and the received MAC addresses and nonces to calculate a shared secret called SAE Key Seed (KS).
The station and the access point use their own KS and the received MAC addresses and nonces to calculate a shared secret called SAE Key Confirmation Key (KCK).
The station and the access point use their own KCK and the received MAC addresses and nonces to calculate a confirmation value called SAE Confirm.
The station and the access point exchange Confirm messages that contain their SAE Confirm values.
The station and the access point verify that the received SAE Confirm values match their own calculated values. If they match, the authentication is successful and the station and the access point have established a shared secret called SAE PMK.
The SAE PMK is different for each session because it depends on the MAC addresses and nonces that are exchanged in each authentication process. The SAE PMK is used as an input for the 4-way handshake that generates the Pairwise Temporal Key (PTK) for encrypting data frames.
The other options are not sources that WPA3-Personal uses to generate a different PMK each time a station connects to the wireless network because:
Opportunistic Wireless Encryption (OWE): OWE is a feature that provides encryption for open networks without requiring authentication or passwords. OWE uses a similar key establishment protocol as SAE, but it does not generate a PMK. Instead, it generates a Pairwise Secret (PS) that is used as an input for the 4-way handshake that generates the PTK.
Simultaneous Authentication of Equals (SAE): SAE is not a source, but a protocol that uses session-specific information as a source to generate a different PMK each time a station connects to the wireless network.
Key Encryption Key (KEK): KEK is not a source, but an output of the 4-way handshake that generates the PTK. KEK is used to encrypt group keys that are distributed by the access point.

NEW QUESTION # 44
Two independent ArubaOS-CX 6300 switches with Spanning Tree (STP) settings are interconnected with two cables between ports 1/1/1 and 1/1/2 All four ports have "no shutdown" and "no routing" commands How will STP forward or discard traffic on these ports?

• A. The switch with the lower MAC address will discard on one port, while the switch with the higher MAC address will forward on both ports
• B. The switch with the lower MAC address will forward on both ports, while the switch with the higher MAC address will discard on one port
• C. The switch with the lower MAC address will discard on one port, while the switch with the higher MAC address will discard on one port
• D. The switch with the lower MAC address will forward on both ports, while the switch with the higher MAC address will forward on both ports

Answer: C

Explanation:
Explanation
The way that STP Spanning Tree Protocol. STP is a network protocol that ensures a loop-free topology for any bridged Ethernet local area network by preventing redundant paths between switches or bridges from creating loops that cause broadcast storms, multiple frame transmission, and MAC table instability. STP creates a logical tree structure that spans all of the switches in an extended network and blocks any redundant links that are not part of the tree from forwarding data packets . will forward or discard traffic on these ports is as follows:
STP will elect a root bridge among the two switches based on their bridge IDs, which are composed of a priority value and a MAC address. The switch with the lower bridge ID will become the root bridge and will forward traffic on all its ports.
STP will assign a role and a state to each port on both switches based on their port IDs, which are composed of a priority value and a port number. The port with the lower port ID will become the designated port and will forward traffic, while the port with the higher port ID will become the alternate port and will discard traffic.
In this scenario, since both switches have two cables connected between ports 1/1/1 and 1/1/2, there will be two possible paths between them, creating a loop. To prevent this loop, STP will block one of these paths by discarding traffic on one of the ports on each switch.
Assuming that both switches have the same priority value (default is 32768), the switch with the lower MAC address will have the lower bridge ID and will become the root bridge. The root bridge will forward traffic on both ports 1/1/1 and 1/1/2.
Assuming that both ports have the same priority value (default is 128), port 1/1/1 will have a lower port ID than port 1/1/2 on both switches because it has a lower port number. Port 1/1/1 will become the designated port and will forward traffic, while port 1/1/2 will become the alternate port and will discard traffic.
Therefore, the switch with the lower MAC address will discard traffic on one port (port 1/1/2), while the switch with the higher MAC address will also discard traffic on one port (port 1/1/2).

PTK is a key that is derived from PMK Pairwise Master Key (PMK) is a key that is derived from PSK Pre-shared Key (PSK) is a key that is shared between two parties before communication begins , ANonce Authenticator Nonce (ANonce) is a random number generated by an authenticator (a device that controls access to network resources, such as an AP) , SNonce Supplicant Nonce (SNonce) is a randomnumber generated by supplicant (a device that wants to access network resources, such as an STA) , AA Authenticator Address (AA) is MAC address of authenticator , SA Supplicant Address (SA) is MAC address of supplicant using Pseudo-Random Function (PRF). PTK consists of four subkeys:
KCK Key Confirmation Key (KCK) is used for message integrity check
KEK Key Encryption Key (KEK) is used for encryption key distribution
TK Temporal Key (TK) is used for data encryption
MIC Message Integrity Code (MIC) key
The subkey that is specifically used for data encryption is TK Temporal Key (TK). TK is also known as Pairwise Transient Key (PTK). TK changes periodically during communication based on time or number of packets transmitted.
The other options are not part of WPA Key Hierarchy because:
PMK: PMK is not part of WPA Key Hierarchy, but rather an input for deriving PTK.
KCK: KCK is part of WPA Key Hierarchy, but it is not used for data encryption, but rather for message integrity check.
Nonce: Nonce is not part of WPA Key Hierarchy, but rather an input for deriving PTK.

• A. Aruba CX 6300
• B. Aruba CX 6000
• C. Aruba CX 6200
• D. Aruba CX 6400

Answer: C

Explanation:
Explanation
The ideal Aruba access switch for a cost-effective connection to 200-380 clients, printers and APs per distribution rack is the Aruba CX 6200. This switch series is a cloud-manageable, stackable access switch series that is ideal for enterprise branch offices and campus networks, as well as SMBs. The CX 6200 series offers the following benefits:
Enterprise-class connectivity: The CX 6200 series supports ACLs, robust QoS, and common protocols such as static and Access OSPF routing.
Power and speed for users and IoT: The CX 6200 series provides built-in 1/10GbE uplinks and 30W to
60W of Class 4 to Class 6 PoE for powering devices such as APs and cameras.
Scalable growth made simple: The CX 6200 series supports Aruba Virtual Switching Framework (VSF) that allows you to quickly grow your network to eight members in a single stack using high-performance built-in 10G SFP ports.
Management flexibility: The CX 6200 series supports a choice of management, including cloud-based and on-prem Central, CLI, switch Web GUI and programmability with AOS-CX operating system, and REST APIs.
The other options are not ideal because:
Aruba CX 6400: This switch series is a high-availability modular switch series that is ideal for versatile edge access to data center deployments. It offers more performance, scalability, and modularity than the CX 6200 series, but it is also more expensive and complex to deploy and manage. It may not be cost-effective for connecting 200-380 clients per distribution rack.
Aruba CX 6300: This switch series is a layer 3 stackable access and aggregation switch series that offers Smart Rate and High Power PoE. It offers more features and performance than the CX 6200 series, but it is also more expensive and may not be necessary for connecting 200-380 clients per distribution rack.
Aruba CX 6000: This switch series is a layer 2 access switch series that offers PoE. It offers less features and performance than the CX 6200 series, and it does not support VSF stacking or routing protocols. It may not be sufficient for connecting 200-380 clients per distribution rack.

NEW QUESTION # 52
You are configuring a network with a stacked pair of 6300M switches used for distribution and layer 3 services. You create a new VLAN for users that will be used on multiple access stacks of CX6200 switches connected downstream of the distribution stack You will be creating multiple VLANs/subnets similar to this will be utilized in multiple access stacks What is the correct way to configure the routable interface for the subnet to be associated with this VLAN?

• A. Create a physically routed interface in the subnet on the 6300M stack for each downstream switch.
• B. Create an SVl in the subnet on the 6300M stack.
• C. Create an SVl in the subnet on the 6300M stack, and assign the management address of each downstream switch stack to a different IP address in the same subnet
• D. Create an SVl in the subnet on each downstream switch

Answer: B

Explanation:
Explanation
The correct way to configure the routable interface for the subnet to be associated with this VLAN is to create an SVI Switched Virtual Interface (SVI) Switched Virtual Interface (SVI) is a virtual interface on a switch that represents a VLAN and provides Layer 3 routing functions for that VLAN . SVIs are used to enable inter-VLAN routing , provide gateway addresses for hosts in VLANs , apply ACLs or QoS policies to VLANs
, etc . SVIs have some advantages over physical routed interfaces such as saving interface ports , reducing cable costs , simplifying network design , etc . SVIs are usually numbered according to their VLAN IDs (e.g., vlan 10) and assigned IP addresses within the subnet of their VLANs . SVIs can be created and configured by using commands such as interface vlan , ip address , no shutdown , etc . SVIs can be verified by using commands such as show ip interface brief , show vlan , show ip route , etc . in the subnet on the 6300M stack.
An SVI is a virtual interface on a switch that represents a VLAN and provides Layer 3 routing functions for that VLAN. Creating an SVI in the subnet on the 6300M stack allows the switch to act as a gateway for the users in that VLAN and enable inter-VLAN routing between different subnets. Creating an SVI in the subnet on the 6300M stack also simplifies network design and management by reducing the number of physical interfaces and cables required for routing.
The other options are not correct ways to configure the routable interface for the subnet to be associated with this VLAN because:
Create a physically routed interface in the subnet on the 6300M stack for each downstream switch: This option is incorrect because creating a physically routedinterface in the subnet on the 6300M stack for each downstream switch would require using one physical port and cable per downstream switch, which would consume interface resources and increase cable costs. Creating a physically routed interface in the subnet on the 6300M stack for each downstream switch would also complicate network design and management by requiring separate routing configurations and policies for each interface.
Create an SVl in the subnet on each downstream switch: This option is incorrect because creating an SVI in the subnet on each downstream switch would not enable inter-VLAN routing between different subnets, as each downstream switch would act as a gateway for its own VLAN only. Creating an SVI in the subnet on each downstream switch would also create duplicate IP addresses in the same subnet, which would cause IP conflicts and routing errors.
Create an SVl in the subnet on the 6300M stack, and assign the management address of each downstream switch stack to a different IP address in the same subnet: This option is incorrect because creating an SVI in the subnet on the 6300M stack, and assigning the management address of each downstream switch stack to a different IP address in the same subnet would not enable inter-VLAN routing between different subnets, as each downstream switch would still act as a gateway for its own VLAN only. Creating an SVI in the subnet on the 6300M stack, and assigning the management address of each downstream switch stack to a different IP address in the same subnet would also create unnecessary IP addresses in the same subnet, which would waste IP space and complicate network management.

NEW QUESTION # 53
What does the status of "ALFOE" mean when checking LACP with "show lacp interfaces'"?

• A. The interface on the local switch is configured as static-LAG
• B. LACP is working fine with no problems
• C. LACP is in a synchronizing process
• D. LACP is not configured on the peer side

Answer: B

Explanation:
Explanation
The status of "ALFOE" means that LACP Link Aggregation Control Protocol (LACP) is a network protocol that provides dynamic negotiation of link aggregation between two devices. LACP allows multiple physical links to be combined into a single logical link for increased bandwidth, redundancy, and load balancing. LACP is defined in IEEE 802.3ad standard. is working fine with no problems when checking LACP with "show lacp interfaces". The status of "ALFOE" is an acronym that stands for:
A: Active - The interface is actively sending LACP packets to negotiate link aggregation with the peer device.
L: Link Up - The interface has physical connectivity with the peer device.
F: Aggregatable - The interface can be aggregated with other interfaces into a single logical link.
D: Synchronized - The interface has successfully negotiated link aggregation parameters with the peer device and can transmit or receive traffic on the logical link.
E: Collecting/Distributing - The interface is collecting incoming traffic from the peer device and distributing outgoing traffic to the peer device on the logical link.
The other options are not correct because:
The interface on the local switch is configured as static-LAG: This option is false because static-LAG does not use LACP to negotiate link aggregation. Static-LAG requires manual configuration of link aggregation parameters on both devices and does not have any status indicators.
LACP is not configured on the peer side: This option is false because if LACP is not configured on the peer side, the status of the interface would be "ALF-" instead of "ALFOE". This means that the interface would not be synchronized or collecting/distributing with the peer device.
LACP is in a synchronizing process: This option is false because if LACP is in a synchronizing process, the status of the interface would be "ALF-O" instead of "ALFOE". This means that the interface would not be collecting/distributing with the peer device.

NEW QUESTION # 54
What are the main characteristics of the 6 GHz band?

• A. The 6 GHz band is fully backward compatible with the existing bands.
• B. In North America, the 6 GHz band offers more 80 MHz channels than there are 40 MHz channels in the
  5 GHz band.
• C. Less RF signal is absorb by objects in a 6 GHz WLAN.
• D. Low Power Devices are allowed for indoor and outdoor usage.

Answer: B

Explanation:
Explanation
The main characteristic of the 6 GHz band that is true among the given options is that in North America, the 6 GHz band offers more 80 MHz channels than there are 40 MHz channels in the 5 GHz band. This characteristic provides more spectrum availability, less interference, and higher throughput for wireless devices that support Wi-Fi 6E Wi-Fi Enhanced (Wi-Fi 6E) is an extension of Wi-Fi 6 (802.11ax) standard that operates in the newly available unlicensed frequency spectrum around 6 GHz in addition to existing bands below it. Some facts about this characteristic are:
In North America, there are up to seven non-overlapping channels available in each of three channel widths (20 MHz, 40 MHz, and 80 MHz) in the entire unlicensed portion of the new spectrum (5925-7125 MHz). This means there are up to 21 non-overlapping channels available for Wi-Fi devices in total.
In comparison, in North America, there are only nine non-overlapping channels available in each of two channel widths (20 MHz and 40 MHz) in the entire unlicensed portion of the existing spectrum below it (2400-2483 MHz and 5150-5825 MHz). This means there are only up to nine non-overlapping channels available for Wi-Fi devices in total.
Therefore, in North America, there are more than twice as many non-overlapping channels available in each channel width in the new spectrum than in the existing spectrum below it.
Specifically, there are more than twice as many non-overlapping channels available at 80 MHz width (seven) than at 40 MHz width (three) in the existing spectrum below it.
The other options are not true because:
Less RF signal is absorbed by objects in a 6 GHz WLAN: This option is false because higher frequency signals tend to be more absorbed by objects than lower frequency signals due to higher attenuation Attenuation is a general term that refers to any reduction in signal strength during transmission over distance or through an object or medium . Therefore, RF signals in a 6 GHz WLAN would be more absorbed by objects than RF signals in a lower frequency WLAN.
The 6 GHz band is fully backward compatible with existing bands: This option is false because Wi-Fi devices need to support Wi-Fi 6E standard to operate in the new spectrum around 6 GHz . Existing Wi-Fi devices that do not support Wi-Fi 6Estandard cannot use this spectrum and can only operate in existing bands below it.
Low Power Devices are allowed for indoor and outdoor usage: This option is false because Low Power Indoor Devices (LPI) are only allowed for indoor usage under certain power limits and registration requirements . Outdoor usage of LPI devices is prohibited by regulatory authorities such as FCC Federal Communications Commission (FCC) is an independent agency of United States government that regulates communications by radio, television, wire, satellite, and cable across United States . However, outdoor usage of Very Low Power Devices (VLP) may be allowed under certain power limits and without registration requirements.
