What are two examples of when a channel extender is required? (Choose two.)
- A. when using Fibre Channel compression
- B. when using replication over an extended distance

Correct Answer: A,B 🗳️
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. reduced cycle time will always reduce your RPO
- C. the amount of data written to the P-Vol
- D. when splitting the pairs, the S-Vol will wait until the next update cycle so a reduced cycle time is important
Correct Answer: A,C 🗳️
A customer is conducting a test and has performed a planned failoverto their Hitachi Universal Replicator copies at the secondary site. They have confirmed their recovery capabilities and they are ready to return operations to the production site.
Which fallback procedure applies?
- A. Copy pace should be reduced until the resync copy is complete.
- B. Replication pairs must be suspended to allow changed tracks to be managed using the bitmap.
- C. A full initial copy will be required from the recovery storage back to the primary storage.
- D. Replication direction can be reversed without need for a full initial copy.
Correct Answer: D 🗳️
A customer is planning to replicate 36 TB of data using asynchronous replication. What are two primary considerations for sizing the expected solution? (Choose two.)
- A. Total number of IOPS for the environment
- B. The percentage of writes for the environment
- C. The amount of latency between the sites
- D. Number of disk units installed at the secondary site
Correct Answer: A,B 🗳️
