HH0-300 Questions and Answers

Question # 6

A customer has TrueCopy with a single cascaded remote ShadowImage solution that they resynchronize every two hours. The customer requires disaster recovery testing to be non-disruptive to production and the replication cycle.

What should be considered while planning a disaster recovery test?

A.

The cascaded ShadowImagevolumes should remain in pair status.

B.

The production applications should be down during disaster recovery testing.

C.

A separate dedicated in-system replication copy should be created for disaster recovery testing purposes.

D.

The TrueCopy secondary volumes should be used for disaster recovery testing purposes.

Question # 7

In which situation should Inflow Control be enabled?

A.

The customer has limited journal disk space.

B.

The customer requires non-replicated transactions to be rejected.

C.

The customer's top priority is to maintain continuous replication.

D.

The customer's top priority is to maintain application response time

Question # 8

A customer is implementing TrueCopy between their primary and secondary data centers. Due to budget constraints the RCU has larger, slower disk drives than the MCU.

What is the risk associated with the design?

A.

Primary volumes may suspend

B.

Journal utilization may increase

C.

Host response time may increase

D.

Back-end director utilization may increase

Question # 9

What are two HDS recommendations when using channel extenders? (Choose two.)

A.

Enable compression on the FCIP ports.

B.

Use the recovery fabric for channel extension.

C.

Use the production fabric for channel extension.

D.

Create a zone for each Initiator-RCU Target pair

Question # 10

A customer is using Hitachi Universal Replicator between two VSPs. They do not currently maintain any point-in-time copies at the remote site. They have determined that they want to perform a disaster recovery test at the remote site using Hitachi Thin Image.

Which two statements are true? (Choose two.)

A.

The Hitachi Thin Image V-Vols will protect against rolling disasters.

B.

The Hitachi Thin Image V-Vols will provide for non-disruptive disaster recovery testing.

C.

The Hitachi Thin Image V-Vols will not protect against site-wide disasters at the primary site.

D.

The Hitachi Thin Image V-Vols will require the same physical disk size as the Hitachi Universal Replicator P-Vols.

Question # 11

A customer has refused to implement a disaster recovery site point-in-time copy. The customer will be exposed to which two risks? (Choose two.)

A.

A logical disaster or failure may affect the disaster recovery site data.

B.

The customer must stop all inter-site replication to perform recovery tests.

C.

The replication products do not function without a point-in-time copy to use forjournaling.

D.

The disaster recovery tests may not succeed from the single copy of disaster recovery site data

Question # 12

Your customer is determined to conduct disaster recovery testing with the Hitachi Universal Replicator volume in a read/write state at the secondary site. The test will take 4 hours and they have a 4-hour RPO.

Which two impacts will this have on their ability to recover from a disaster? (Choose two.)

A.

The customer will exceed their RPO at the end of the test.

B.

The customer will have protection from logical corruption during the test.

C.

The customer will be at risk from a disaster at the primary site.

D.

The customer will be within their RPO at the end of the test.

Question # 13

A customer implements TrueCopy replication for an active OLTP database and users begin to complain about database response time. The customer is running Fiber Channel over DWDM and the peak write workload only consumes half of the available bandwidth on the link.

Which factor affects the database response time?

A.

Insufficient MCU cache has activated inflow control.

B.

Cache configurations of the RCU and MCU do not match.

C.

The distance between the sites introduces too much latency.

D.

The distance between the sites is too great for Fiber Channel to maintain session

Question # 14

A customer wants to replicate 20 TB of data asynchronously on a VSP. They have two different applications and would like to control failover of the applications independent of each other.

How much additional cache is required to support replication for the RCU?

A.

0 GB

B.

5 GB

C.

7 GB

D.

14 GB

Question # 15

Which two benefits does Hitachi Thin Image provide? (Choose two.)

A.

It makes more than 10 copies of primary volumes.

B.

Suspended pairs do not impact host performance.

C.

It protects data against physical hardware failures.

D.

It can make copies with less storage than the P-Vol consumes.

Question # 16

A customer is replicating a database with a five minute RPO between two HUS 150 arrays. They have workload bursts that exceed their available bandwidth.

Which replication technology would meet this requirement?

A.

Hitachi High Availability Manager

B.

TrueCopy

C.

Hitachi Universal Replicator

D.

TrueCopy Extended Distance
