Explanation:
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.

Explanation:
Unity Connection is dependent on Java for some of the components to work.
Incorrect Answers:
B: Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks.
D: As the traffic is within the same physical subnet a firewall would have no effect.

Explanation:
UnityVSA supports the Fully Automated Storage Tiering for Virtual Pool (FAST VP) feature for both block and file data. FAST VP optimizes storage utilization by automatically moving data between and within the storage tiers.

Explanation:
To fully configure asynchronous replication between systems, you must do each of following:
- Configure connectivity for the replication interfaces used by asynchronous replication
- Configure the replication connection between systems
- Configure replication sessions between systems
Note: To fully configure synchronous replication, you must complete each of following:
- Configure connectivity for the synchronous replication interfaces
- Create the synchronous replication management ports
- Configure the replication connection between systems
- Configure replication sessions between systems

정답:
Explanation:
Upon installation and activation of the feature, the following keys are generated by RSA BSAFE and persisted to the Lockbox:
- KEK Wrapping Key (KWK)
- Data Encryption Keys (DEKs) for all bound drives
A new KEK is generated each time the array boots. The KEK is wrapped with the KWK and passed to the SAS controller during the system boot process. Using the persisted KWK, the SAS controller can decrypt the KEK.
Incorrect Answers:
D: Self-Encrypting Drive (SED) technology is another variation of D@RE which is widely used and offers similar functionality as CBE.
However, with SEDs, you have to pay a premium on every drive and only certain drives are offered in SED form.

정답:
Explanation:
FAST VP accelerates performance of a specific storage pool by automatically moving data within that pool to the appropriate drive technology, based on data access patterns. FAST VP is only applicable to hybrid pools. FAST VP is most effective if data relocations occur during or immediately after normal daily processing. EMC recommends scheduling FAST VP relocations to occur before backups or nightly batch processing.
정답:
Explanation:
In addition to being created ahead of time on the Snapshot Schedules page, new snapshots schedules may also be created during the process of creating a new storage resource from within the creation wizard as an alternative to selecting an existing schedule.
Incorrect Answers:
C: In addition to being taken manually, snapshots can also be scheduled to be taken automatically at specific times or frequencies.

Explanation:
As a reminder, UnityVSA displays several alerts in Unisphere prior to the license expiration date.
The table below shows when alerts are generated leading up to the expiration date.
