QUESTION 18
Dorado V6 supports both scale-out and scale-up.

True

False

QUESTION 19
Which software architecture does the OceanStor V5 use?

Parallel block and FS architecture

FS-based block architecture

Block-based FS architecutre

QUESTION 20
Before the PoC test for Dorado V3, which of the following statements about Dorado V3 test is true (same with Dorado V6)?

We need to collect the host type and version.

We need to collect the application type of example, database, VDf, etc.

We should try to collect the I/O block size from application. Then we can select a suitable I/O block siza when we create LUNs.

All of the above.

QUESTION 21
Which statement about the Dorado’s global garbage collection (GC) are correct? (Multiple choice)

Dorado supports intelligent adjustment of multiple GC levels based on the garbage percentage and CPU usage.

When a conflict cocurs, user I/Os and metadata always have a higher priority than GC.

Global GC issues TRIM commands to trigger GC on SSDs.

QUESTION 22
Which problems can continuous mirroring solve? (Multiple Choice)

Two controllers fail at the same time

Two controllers fail at an interval of 20 minutes.

Two controllers fail at an interval of 10 seconds.

The customer has not replaced it within 10 days after the controller fails.

Clone CG

Asynchronous remote replication CG

Snapshot CG

HyperMetro CG e. 3DC CG

QUESTION 24

Synchronous replication

Active-active

Asynchronous replication

Volume mirroring

QUESTION 25
Which statement about the DR star for OceanStor V5 is true? (Multiple choice)

Active-active + asynchronous replication + asynchronous replication (standby).

Asynchronous replication + asynchronous replication + asynchronous replication (standby)

Synchronous + asynchronous replication + asynchronous replication (standby)

QUESTION 26

Serial networking

Parallel networking

Ring networking

QUESTION 32
Which of the following are benefits of front-end interconnect (shared) I/O modules? (Multiple choice)

Host path loss prevention in the event of controller failure, controller hard/software upgrades, and even single FC 1 between host and storage.

Storage sysadmins are needed to ensure the multipath software in servers runs online before controller upgrades.

Fewer front-end modules and host links needed.

Direct data dispatch to the distributed controllers through front-end modules in one controller enclosure.
