Question No : 1


Which Directory Services can be configured in the Unisphere Settings window?

정답:

Question No : 2


When the LUN Snapshot Attach to Host operation is performed, what does the Unity system optionally do before beginning the attach process?

정답:

Question No : 3


When a storage resource has a snapshot taken of it, where are writes to the storage resource written?

정답:

Question No : 4


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?

정답:
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.

Question No : 5


A system administrator has installed the Unity Connection Utility on a Microsoft Windows host. The Windows host is connected to the same physical subnet as a newly installed Unity storage system. When the utility is run, it does not discover any Unity storage systems.
What should be checked on the host that may be preventing the utility from discovering any Unity storage systems?

정답:
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.

Question No : 6


Which Unity feature benefits oracle OLTP environments by improving storage utilization?

정답:
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.

Question No : 7


A storage administrator wants to add as asynchronous replication session to a pair of Unity systems with an existing synchronous replication session that is operating correctly.
Which configuration steps are needed?

정답:
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

Question No : 8


A system administrator is browsing their local management station for a Unity license file.
Which file extension is used for Unity license files?

정답:
Explanation:
You need to obtain the license file (.lic) from the EMC license management web site.

Question No : 10


Where do the D@RE encryption/decryption functions occur in the Unity storage system?

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.

Question No : 11


Through which protocols are backend storage provisioned to the ESXi host when deploying a UnityVSA system?

정답:
Explanation:
UnityVSA supports SMB, NFS, and iSCSI.
References: https://www.emc.com/collateral/TechnicalDocument/docu69362.pdf (page 4)

Question No : 12


Which operation can be performed from the FAST VP settings section in the Unisphere Settings window?

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.

Question No : 13


A storage administrator wants to create a series of daily snapshots for an existing critical LUN.
How can the snapshots be created?

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.

Question No : 14


What is the minimum memory requirement for a host running VMware ESXi 6.0 to support the deployment of a UnityVSA system?

정답:
Explanation:
A minimum of 12 GB RAM per UnityVSA VM is recommended.

Question No : 15


How long before a license expires will UnityVSA send the first alert warning?

정답:
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.
