NEW QUESTION 72
A Unity 400 system has Data at Rest Encryption licensed and enabled. Which operation(s) must be
performed from the Unisphere Settings window to ensure the system is still operational after SP
replacements?
- A. Download Audit Log
- B. Download Checksum
- C. Download Audit Log and Checksum
- D. Backup Keystore File
Answer: D
Explanation:
Explanation/Reference:
The keystore is tied to the storage processors, so care must be taken when performing service operations
in order to preserve the encryption keys. In the event that the chassis and both storage processors need to
be replaced, both storage processors should not be replaced at the same time. Instead, the chassis
replacement should be followed while retaining one SP until the array is back online before replacing the
second SP. In the case that storage processors have already been replaced at the same time and the
keystore was lost, the keystore may be restored from an external backup.
NEW QUESTION 73
How long will a Copy Back operation take when a hot spare is invoked?
- A. Copy Back time depends on the disk capacity
- B. Pro-Active hot spare does not use a Copy Back operation
- C. Copy Back time depends on the disk type
- D. Copy Back time depends on the RAID type
Answer: D
Explanation:
Note: Starting with Release 24, you can now use a proactive hot spare for proactive disk replacement. Before Release 24 you had to remove the physical disk to replace in order to force a rebuild. During the rebuild phase, the RAID group was "degraded" and at risk.
Resolution:
Three main benefits of using a proactive hot spare:

A storage administrator is required to test a new version of an application loaded on a secondary host. The
administrator must use existing data contained on a LUN provisioned from Unity to a primary host.
Which solution will meet the requirement and provide space efficiency?
- A. Create a snapshot of the LUNConfigure snapshot access to the LUN for the secondary hostAttach the
