Question 1

In HUAWEI OceanStor V3, for synchronous replication to be successful, all host applications must be paused during the replication update process.

Correct Answer: A
insert code

Question 2

Which statements are incorrect about remote replication and HyperMetro features of storage systems? (Select all that apply)

Correct Answer: B,D
According to Huawei's BCManager and HyperReplication guides, " incorrect " statements must be identified to understand the distinction between disaster recovery (DR) and active-active solutions. Option B is incorrect because while HyperMetro supports automatic transparent failover (zero RTO) using a Quorum Server, standard synchronous remote replication typically requires manual intervention or third-party management software to trigger a switchover when the primary site fails. In synchronous replication, the secondary LUN is usually in a read-only state and cannot take over automatically without administrative action.
Option D is incorrect because it describes an " Active-Active " state. In a standard Remote Replication pair, only the primary LUN is accessible for host I/O (Read/Write), while the secondary LUN is locked to maintain data consistency. Only the HyperMetro feature allows both LUNs in the pair to provide simultaneous read and write services to application servers across different sites. Regarding distance, while asynchronous replication is physically less constrained, synchronous and HyperMetro technologies are strictly limited by latency (typically requiring round-trip time < 10ms and distance within 100km to 300km depending on the specific product line) to avoid severe application performance degradation.

Question 3

Does OceanStor F V5 support 3.5-inch SSDs?

Correct Answer: A
insert code

Question 4

HyperSnap requires a full copy of data.

Correct Answer: B
insert code

Question 5

Which of the following API can be used to upload objects?

Correct Answer: A
The put object API is the standard operation used in object storage systems (including Huawei OBS and S3-compatible platforms) to upload data. It allows a client to send a complete object - consisting of the data and its associated metadata - to the storage system in a single request.
This operation creates a new object if it does not exist or overwrites it if it already exists.
