According to the physical location of the NAS engine and storage device, the NAS is divided into: (multiple choices)

• A. External NAS
• B. Unified NAS
• C. Internal NAS
• D. Gateway NAS

Answer: B,D

Explanation:
Analysis: NAS mainly has three types of implementation: unified, gateway and scale-out. Unified NAS Use a unified storage platform to merge NAS-based and SAN-based data access, providing two rings that can be managed simultaneously Unified management interface of the environment. The gateway NAS uses external storage to access data. The management operations of the gateway NAS and storage are divided into It's open. Scale-out NAS can combine multiple nodes to form a clustered NAS system.

 

NEW QUESTION 87
Description 1: HyperMirror has a LUN failure, the host service is not interrupted, the HyperClone primary LUN fails, and the host service is interrupted.
Description 2: HyperMirror supports dual copies, HyperClone supports a maximum of 1 master LUN: 16 slave LUN mode.

• A. description 1 is wrong, description 2 is correct
• B. description 1 is correct, description 2 is wrong
• C. description 1 is correct, description 2 is correct
• D. description 1 is wrong, description 2 is wrong

Answer: B

Explanation:
Analysis: HyperMirror (volume mirroring): by providing two mirrored physical copies for local LUNs or LUNs of third-party storage systems, continuous redundant backup protection of LUNs, thereby improving LUN reliability, reducing disaster risk and operation and maintenance costs . HyperClone (clone) can achieve full backup of LUN level without interrupting the host business, available

• A. There is no limit to the network distance of synchronous replication
• B. Asynchronous remote replication, when a disaster occurs, data will be lost from the center
• C. Synchronous remote replication will affect the performance of the host, while asynchronous remote replication will not affect the performance of the host
• D. Synchronous replication is to replicate real-time data, and asynchronous replication is to replicate periodic replication

Answer: B,C,D

 

NEW QUESTION 93
A company purchasing a set of Huawei storage services needs to provide file services while providing block services. Which of the following is correct?

• A. Support non-domain environment
• B. Support CIFS and NFS deployment on the same network
• C. Support AD domain environment

Answer: D

 

NEW QUESTION 94
SAN is a storage architecture that connects storage device and application servers through network.

• A. FALSE
• B. TRUE

Answer: B

 

NEW QUESTION 95
During data center construction, a media company purchased storage devices from multiple vendors. The CTO wants to centrally manage these devices through storage virtualization. Which function is NOT provided by storage virtualization?

• A. Enabling servers to directly access storage hardware
• B. Supporting unified deployment and management
• C. Reducing the limitations of physical storage capacity
• D. Hiding the complexity of physical devices

Answer: A

Explanation:
Storage virtualization does not enable servers to directly access storage hardware. Instead, it creates a virtual layer between the physical storage devices and the servers, allowing the servers to access the storage devices through a single interface. This virtual layer also allows the storage devices to be centrally managed, and can be used to reduce the limitations of physical storage capacity and hide the complexity of physical devices.

 

NEW QUESTION 96
An enterprise needs to purchase backup media for data backup. It must inherit the enterprise's original tape backup structure and strategy and increase the backup speed. What kind of backup media does this company buy?

• C. Disk array
• D. CD Tower

Answer: B

 

NEW QUESTION 97
In the Huawei storage system using RAID2.0+ technology, regarding the difference between Thick LUN and Thin LUN, the following Which description is correct? (Multiple choices)

• A. The storage capacity is not allocated by default when the Thin LUN is created, and the storage capacity is allocated when data is written
• B. Thin LUN is more flexible than Thick LUN, and has better performance during sequential read and write of large IO
• C. Allocate storage capacity when Thick LUN is created
• D. Thin LUN makes the entire storage space utilization rate higher

Answer: A,C,D

Explanation:
Resolution: A LUN can be created as a Thick LUN and Thin LUN. Thick LUN will be allocated from the storage pool in advance Storage capacity, even if no user data is stored on the Thick LUN. Thin LUNs are not pre-allocated from the storage pool For storage capacity, only when user data is written to the thin LUN will the actual storage capacity be allocated from the storage pool.
Sequential read: Since thin LUN dynamically allocates storage resources according to the actual needs of users, space allocation exists in time Discontinuity, so it will affect the continuity of the space mapped on the disk. When thick LUN is created, the system Automatic resource allocation technology allocates storage resources from storage resources at one time, which maximizes its mapping to Space continuity on the disk. Sequential reading of mechanical disks is more efficient, so thick LUNs perform better when reading sequentially For thin LUN.

 

NEW QUESTION 98
In the scenario where only 2 disks are in the RAID group, which one of the following uses data striping?

• A. RAID 5
• B. RAID 0
• C. RAID 1
• D. RAID 6

Answer: B

Explanation:
RAID 0 is a data striping technique that involves distributing data across two or more disks, which allows for increased performance and capacity. RAID 0 does not provide redundancy, and if any of the disks in the RAID group fail, the data will be lost. RAID 5 and RAID 6 are both data striping techniques, but they also provide redundancy, which means that the data is still recoverable even if one or more disks in the RAID group fail. RAID 1 is a data mirroring technique, which involves writing the same data to two disks, and does not use data striping.
