Hitachi HITACHI DATA SYSTEMS CERTIFIED EXPERT -REPLICATION SOLUTIONS ARCHITECT Sample Questions:
A customer has a HUS 130 array and wants an asynchronous solution. The customer needs to understand which factors influence the TrueCopy Extended Distance cycle time.
Which two factors should be considered? (Choose two.)
- A. the maximum amount of data loss the operation could survive during a disaster
- B. the amount of data written to the P-Vol
- C. when splitting the pairs, the S-Vol will wait until the next update cycle so a reduced cycle time is important
- D. reduced cycle time will always reduce your RPO
A customer is using a multi-target Three Data Center Delta Resync configuration with A as the primary copy, B as a TrueCopy copy, and C as a Hitachi Universal Replicator copy. The customer performs a planned outage at the primary facility, fails over, and begins running production from the synchronous copy (B).
What happens when the customer is ready to resume replication?
- A. Copies A and C can be resynchronized using an incremental copy.
- B. Only the Hitachi Universal Replicator C copy can be resynchronized using an incremental copy.
- C. Only the TrueCopy A copy can be resynchronized using an incremental copy.
- D. Copies A and C require a full initial copy.
A customer's production facilities are located several hundred kilometers apart. The customer is cost conscious and wants to reduce recurring expenses.
Which two replication strategies would be used to balance recoverability versus bandwidth costs? (Choose two.)
- A. journal-based asynchronous replication
- B. mediated point-in-time copy replication
- C. synchronous replication
- D. in-system replication to virtualized storage
A customer is using 10 GB of a 32 GB non-HDP LDEV. They plan to replicate this data using Hitachi Universal Replicator to a HDP LDEV on a secondary array.
What should the customer consider when planning to replicate to an HDP volume?
- A. The secondary volume will consume the amount of the used data on the primary LDEV in the HDP pool.
- B. The secondary volume will consume the amount of the entire primary LDEV in the HDP pool.
- C. A cascaded ShadowImagecopy from the secondary volume must be an HDP volume.
- D. A cascaded ShadowImagecopy from the secondary volume must be a normal volume.
What are two factors in determining the impact to host response time when replicating data using TrueCopy over Fiber Channel links? (Choose two.)
- A. bandwidth available between sites
- B. the speed of the Fiber Channel switch
- C. the distance between the sites
- D. the speed of the disk drives
