Huawei HCSA-Presales-Storage V4.0 Sample Questions (Q118-Q123):

NEW QUESTION # 118
For hot and cold data, SmartTier can only use the SAS and NbSAS tiers for storage.

A. TRUE
B. FALSE

Answer: B

NEW QUESTION # 119
Which statements are incorrect about remote replication and HyperMetro features of storage systems? (Select all that apply)

A. Asynchronous remote replication has no limit on the distance.
B. Synchronous remote replication and HyperMetro technologies require that the distance does not exceed 300 km.
C. Both LUNs in a remote replication pair can provide services for servers.
D. HyperMetro and synchronous remote replication technologies can implement automatic switchover upon a storage system fault.

Answer: C,D

Explanation:
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.

NEW QUESTION # 120
Dorado V3 supports NVMe SSDs

A. FALSE
B. TRUE

Answer: B

NEW QUESTION # 121
Which of the following scenarios does NAS Write Once Read Many (WORM) apply to? (Choose all that apply.)

A. E-contracts
B. Online exams
C. Data archiving
D. Database

Answer: A,B,C

Explanation:
NAS WORM is designed for scenarios that require data to be written once and protected from modification or deletion for a defined retention period. This makes it ideal for data archiving, e- contract preservation, and online exam records, all of which require immutable, audit-compliant storage. Databases are not suitable because they require frequent updates and deletions, which WORM does not allow.

NEW QUESTION # 122
What kind of data flows is supported by SmartMobility of OceanStor Dorado?

A. SAN
B. NAS
C. Object
D. HDFS

Answer: A,B

Explanation:
SmartMobility in OceanStor Dorado focuses on supporting SAN and NAS environments, optimizing data migration and access within these protocols, while HDFS and Object storage flows are not typically included in its supported data flows.
SmartMobility of OceanStor Dorado primarily supports SAN and NAS data flows rather than covering all types listed. HDFS and Object storage flows are not directly supported by SmartMobility.
