NEW QUESTION 135
You created a public subnet and an internet gateway in your virtual cloud network (VCN) of Oracle Cloud Infrastructure. The public subnet has an associated route table and security list. However, after creating several compute instances in the public subnet, none can reach the Internet.
Which two are possible reasons for the connectivity issue? (Choose two.)
- A. There is no dynamic routing gateway (DRG) associated with the VCN.
- B. There is no stateful ingress rule in the securitylist associated with the public subnet.
- C. A NAT gateway is needed to enable the communication flow to internet.
- D. The route table has no default route forrouting traffic to the internet gateway.
- E. There is no stateful egress rule in the security list associated with the public subnet.
Answer: D,E
Explanation:
Explanation
An internet gateway as an optional virtual router that connects the edge of the VCN with the internet. To use the gateway, the hosts on both ends of the connection must have public IP addresses for routing. Connections that originate in your VCN and are destined for a public IP address (either inside or outside the VCN) go through the internet gateway. Connections that originate outside the VCN and are destined for a public IP address inside the VCN go through the internet gateway.
Working with Internet Gateways
You create an internet gateway in the context of a specific VCN. In other words, the internet gateway is automatically attached to a VCN. However, you can disable and re-enable the internet gateway at any time.
Compare this with a dynamic routing gateway (DRG), which you create asa standalone object that you then attach to a particular VCN. DRGs use a different model because they're intended to be modular building blocks for privately connecting VCNs to your on-premises network.
For traffic to flow between a subnet and an internetgateway, you must create a route rule accordingly in the subnet's route table (for example, destination CIDR = 0.0.0.0/0 and target = internet gateway). If the internet gateway is disabled, that means no traffic will flow to or from the internet even if there's a route rule that enables that traffic. For more information, see Route Tables.
For the purposes of access control, you must specify thecompartment where you want the internet gateway to reside. If you're not sure which compartment to use, put the internet gateway in the same compartment as the cloud network. For more information, see Access Control.
You may optionally assign a friendly name to the internet gateway. It doesn't have to be unique, and you can change it later. Oracle automatically assigns the internet gateway a unique identifier called an Oracle Cloud ID (OCID). For more information, see Resource Identifiers.
To delete an internet gateway, it does not have to be disabled, but theremust not be a route table that lists it as a target.
AS per compute instances can connect to the Internet so you use egress no ingress

You must implement a backup solution for your AutonomousData Warehouse (ADW) that will enable you to restore data as old as one year with a recovery point objective (RPO) of 10 days.
Which database backup strategy would you select?
- A. Take quarterly manual backups to supplement the automated backups and preserve them for 12 months.
- B. Take monthly manual backups to supplement the automated backups and preserve them for 12 months.
- C. Use the automated backups.
- D. Take weekly manual backups to supplement the automated backups and preservethem for 12 months.
Answer: C
Explanation:
Explanation
Oracle Cloud Infrastructure automatically backs up your Autonomous Databases and retains these backups for
60 days. Automatic backups are weekly full backups and daily incremental backups. You can also create manual backups to supplement your automatic backups. Manual backups are stored in an Object Storage bucket that you create, and are retained for 60 days The retention period for manual backups is the same as automatic backups which is 60 days. So we cannot preserve the backup for 12 months

NEW QUESTION 154
Which statement is true about Data Guard Implementation in DB systems?
- A. Both DB systems must be in the same compartment, and they must be the same shape
- B. You cannot manage Oracle database initialization parameters at a global level.
- C. You can define the backup window and set custom backup retention period for the automatic database backup schedule.
- D. You cannot manage the database as sys/sysdba.
Answer: A
Explanation:
Explanation
An Oracle Data Guard implementation requires two DB systems, one containing the primary database and one containing the standby database. When you enable Oracle Data Guard for a virtual machine DB system database, a new DBsystem with the standby database is created and associated with the primary database. For a bare metal DB system, the DB system with the database that you want to use as the standby must already exist before you enable Oracle Data Guard.
Requirement details are as follows:
- Both DB systems must be in the same compartment.
- The DB systems must be the same shape type (for example, if the shape of the primary database is a virtual machine, then the shape of the standby database can be any other virtual machine shape).
- If your primary and standby databases are in different regions, then you must peer the virtual cloud networks (VCNs) for each database. See Remote VCN Peering (Across Regions).
- Configure the security list ingress and egress rules for thesubnets of both DB systems in the Oracle Data Guard association to enable TCP traffic to move between the applicable ports. Ensure that the rules you create are stateful (the default).

NEW QUESTION 156
You are deploying a highly available web application InOracle Cloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs).
How many subnets should you create to deliver a secure, highly available application?
- A. two subnets in total; one regional public subnet to host your back-end web servers and one regional private subnet to host your public load load balancer.
- B. three subnets in total; one regional public subnet to host your back-end web servers and two AD specific private subnets to host your private load load balancer.
- C. two subnets in total; one regional private subnet to host your back-end web servers and one regional public subnet to host your public load load balancer.
- D. one subnet in total; one regional private subnet to host your back-end web servers and your public load balancer.
Answer: C
Explanation:
Explanation
To accept traffic from the internet, you create a public load balancer. The service assigns it a public IP address that serves as the entry point for incoming traffic. You can associate the public IP address with a friendly DNS name through any DNS vendor.
A public load balancer is regional in scope. If your region includes multiple availability domains, a public load balancer requires either a regional subnet (recommended) or two availability domain-specific (AD-specific) subnets, each in a separate availability domain. With a regional subnet, the Load Balancing service creates a primary load balancer and a standby load balancer, each in a different availability domain, to ensure accessibility even during an availability domain outage. If you create a load balancer in two AD-specific subnets, one subnet hosts the primary load balancer and the other hosts a standby load balancer. If the primary load balancer fails,the public IP address switches to the secondary load balancer. The service treats the two load balancers as equivalent and you cannot specify which one is "primary".
Whether you use regional or AD-specific subnets, each load balancer requires one privateIP address from its host subnet. The Load Balancing service supplies a floating public IP address to the primary load balancer.
The floating public IP address does not come from your backend subnets.
You cannot specify a private subnet for your public load balancer.
The backend servers (Compute instances) associated with a backend set can exist anywhere, as long as the associated network security groups (NSGs), security lists, and route tables allow the intended traffic flow.
Oracle recommends that you create your load balancer in a regional subnet.
Oracle recommends that you distribute your backend servers across all availability domains within the region.

- B. foursubnets in total; one subnet in each AD for the web servers and a single subnet in any one AD for the load balancer
- C. three subnets in total; one subnet in each AD
- D. five subnets in total; two subnets each in the first and second AD with a single subnet in the third AD
