H13-624_V5.5 Practice Questions

A.  

SPC-2 applies to scenarios where random small I/Os are quickly responded.

B.  

SPC-1 applies to scenarios of sequential large I/O access.

C.  

SPC-2 applies to scenarios of sequential large I/O access.

D.  

SPC-2 is used to test the SAN array performance in the OLPT, database, and email application scenarios.

A.  

Interrupted

B.  

Paused

C.  

Faulty

D.  

Migrating

A.  

TRUE

B.  

FALSE

A.  

TRUE

B.  

FALSE

A.  

To be recovered

B.  

Synchronizing

C.  

Normal

D.  

Split

A.  

Small storage space occupation: A clone generated by the storage system is not a full physical data copy, which does not occupy large storage space.

B.  

Quick generation: The storage system can generate a clone within several seconds to obtain the consistent copy of the source volume data.

C.  

Lossless performance: Based on the ROW mechanism, the done write performance is equivalent to the source volume write performance.

D.  

Cascading: Clones can be created based on clone volumes or snapshots of clone volumes in the storage system. A maximum of 64 cascading levels are supported.

A.  

The engineer has manually adjusted the time of the cluster nodes. As a result, the conflict handling is different.

B.  

NTP synchronization is not configured for the cluster, and different NTP time sources are used.

C.  

Namespaces with the same name have been created under the same account.

D.  

The Network Time Protocol (NTP) clock in the storage cluster is inconsistent with the clock of the client that accesses object services.

A.  

When the data is read using the DPC or NFS protocol, the SED obtains the identity authentication key from the key management server, reads and decrypts the ciphertext data, and then returns the plaintext data to the protocol layer. The protocol layer returns the plaintext data to client applications.

B.  

This feature supports encrypted data write using NFS, CIFS, HDFS, or S3. Data is decrypted and read using NFS, CIFS, HDFS, or S3.

C.  

The file service client can write plaintext data through the NFS/CIFS/DPC protocol.

D.  

Huawei OceanStor Pacific series scale-out storage supports disk encryption. All data delivered by services is stored on self-encrypting disks (SEDs).

A.  

TRUE

B.  

FALSE

A.  

In terms of data reliability, multiple RAID policies are supported based on the traditional disk-level RAID mode.

B.  

The product adopts Kunpeng processors to integrate functions of multiple chips and effectively improve hardware reliability.

C.  

The product leverages link aggregation to ensure transmission link redundancy and performs link switchover or isolation to ensure service continuity if a link becomes faulty or subhealthy.

D.  

The product uses the multi-copy technology to implement the intra-node RAID function. If a node is faulty, the system reliability is not degraded and even remains higher than that of the EC mechanism.
