QUESTION 262
Which of the following statements about Thin LUN are correct? (Multiple Choice)

After the Smart Thin feature is enabled, users can create Thin LUNs larger than the maximum physical free space of the storage pool

Thin LUN cannot be directly converted to Thick LUN

All LUNs in a storage pool need to enable the Smart Thin function

When Thin LUN is created, it consumes little storage capacity

QUESTION 263
Regarding Huawei’s OceanStor V3 storage dynamic tiered storage technology, which of the following descriptions is wrong?

Smart Tier calculates and analyzes the activity of the data to determine the activity level of the data

Smart Tier automatically and dynamically moves data to storage media of different performance according to the different activity levels of the data

Smart Tier data movement based on configuration data migration strategy

Data statistics, analysis and data migration of Smart Tier features will affect business continuity and data availability

QUESTION 264
Which of the following has the highest performance?

SLC

MLC

TLC

QLC

QUESTION 265
The SCSI bus assigns a unique ID to each device, and can support up to 8 devices. On the one hand, the device ID is used to address and the other is to identify the priority of the device in the use of the bus.

TRUE

FALSE

QUESTION 266
Which of the following descriptions is correct?
Description 1: LUN is composed of multiple Extents in the storage pool.
Description 2: LUN can contain one or more types of Extent.

Description 1 is correct, description 2 is correct

Description 1 is correct, description 2 is wrong

Description 1 is wrong, description 2 is correct

Description 1 is wrong, description 2 is wrong

QUESTION 267
The RDMA protocol can achieve direct access to the memory of the remote device. RDMA achieves ultra-low latency between endpoints, ultra-high throughput transmission, and does not require cpu, os intervention does not need to consume too many other resources for the processing and transmission of network data.

True

False

QUESTION 268
The RTO=0 and RPO=0 of the disaster recovery center in the same city.

True

False

QUESTION 269
In the case of using RAID 2.0+ technology, Thick LUN is composed of Grain, and Thin LUN is composed of Extent.

True

False

QUESTION 270
The RTO in the metrics for disaster recovery systems refers to the point in time target requirements at which the system and data must be restored after a disaster occurs.

True

False

QUESTION 271
For random accessing to mechanical disks, the biggest impact on the time taken to complete an IO is:

Seek time

Rotation delay

Data transfer time

QUESTION 272
In the Huawei storage system using RAID 2.0+ technology, regarding the difference between Thick LUN and Thin LUN, which of the following descriptions is correct? (Multiple choice)

Allocate storage capacity when Thick LUN is created

When Thin LUN is created, storage capacity is not allocated by default. Storage capacity is allocated only when data is written.

Thin LUNs are more flexible than Thick LUNs and have better performance when reading and writing large IOs sequentially

Thin LUN makes the overall storage space utilization higher

QUESTION 273
If a user cares about reliability and random write performance, what RAID level would you recommend?

RAID 10

RIAD 50

RIAD 1

RAI DO

QUESTION 274
Common backup topologies include Lan-Base, Lan-Free, and Server-Base.

True

False

QUESTION 275
The server installed Linux operating system accesses the disk array based on the RAID 5 strategy, and the access path sequence is:

File System->Application System->Volume->I/O Subsystem->RAID Controller->Disk

Application System->File System->Volume->I/O Subsystem->RAID Controller->Disk

Application System -> File System -> I/O Subsystem -> Volume -> RAID Controller -> Disk

Application System->File System->Volume->RAID Controller->I/O Subsystem->Disk

QUESTION 276
Which of the sequence of the overall reconstruction process is correct?
1. Query all CKG with CK falling on the faulty disk
2. Allocate hot spare CK to all these CKG
3. Update the CKG information to release the reconstructed CK
4. Write the reconstructed data to the hot standby CK
5. Through the RAID algorithm,
Calculate the data on the failed disk based on the data on the normal disk and the check disk

1->2->5->4->3

1->2->3->5->4

5->1->2->3->4

5->2->1->4->3

QUESTION 277
Regarding the LUN deduplication of OceanStor V3, which of the following statement is wrong?

The deduplication function is used together with Smart Cache to accelerate performance

The heterogeneous array LUNs taken over support block-level deduplication

Deduplication and remote replication cannot coexist on the same LUN

A deduplicated LUN is selected when creating a LUN, and it cannot be restored to a state without deduplication

QUESTION 278
Regarding the NFS write mode in the Huawei OceanStor V3 storage system, which of the following is correct?

Synchronous mode is to write the shared data to the cache, and then write it to the disk

Asynchronous mode is to write shared data to the hard disk immediately

The system defaults to asynchronous write mode

The system defaults to synchronous write mode

QUESTION 279
Which of the following descriptions about DAS is wrong?

DAS is a designated storage device directly connected to the server that uses them.

DAS is divided into internal DAS and external DAS

The hard disk inside the server is not DAS

External DAS can be connected to the server that accesses them through FC protocol or SCSI protocol.

QUESTION 280
Which of the following descriptions of RAID striping related concepts are correct? (Multiple Choice)

Striping technology divides a continuous piece of data into many small parts and stores them on different disks.

Single or multiple consecutive sectors in a single hard disk form a strip, which is the element that makes up the strip

Striping is a technology that automatically balances the I/O load to multiple physical hard drives

After striping, the speed that the RAID group can provide is faster than that of a single disk
