Question 5

A customer is using Hitachi Universal Replicator with two Virtual Storage Platform arrays. Journal disk utilization is 10 percent, but both network replication links only show 60 percent link utilization.

What is causing the problem?

Options:

A.

unequal latency between the two replication WAN links

B.

insufficient workload from the hosts to saturate the link

C.

unequal size between the P-Vol and S-Vol HDP pools

D.

insufficient bandwidth for the workload being replicated

Question 6

You are designing an asynchronous replication solution for a customer. The customer would like to replicate a database and transaction logs. The customer experienced an unplanned outage.

In this scenario, which statement is true?

Options:

A.

Log volumes will contain all transactions.

What are two ways to reduce the resynchronization impact on host performance? (Choose two.)

Options:

A.

Put the SI S-Vols in a separate CLPR.

B.

Keep the SI pairs in PAIR state.

C.

Run an SI quick split.

D.

Run an SI resync during non-peak hours.
