Q135. A storage administrator must configure replication from a production Dell Unity XT 680F to an offsite DR Dell Unity XT 480. Block resources must be replicated without data loss if the production site becomes unavailable. File resources can be replicated with an acceptable amount of data difference on the destination.
What replication configuration meets the requirements?

Set Unisphere resource filtering to All.

Configure the replication connection mode to Both.

Set an RPO of 0 on the synchronous replication sessions.

Configure the replication interfaces on the 4-port mezzanine card.

Explanation
To meet the requirements, the replication connection mode must be set to Both, which allows both synchronous and asynchronous replication sessions to be configured on the same connection. This way, block resources can use synchronous replication, which ensures zero data loss, and file resources can use asynchronous replication, which allows some data difference on the destination. Setting Unisphere resource filtering to All is not necessary, as it only affects the display of resources in the Unisphere GUI. Setting an RPO of 0 on the synchronous replication sessions is redundant, as synchronous replication always has an RPO of 0. Configuring the replication interfaces on the 4-port mezzanine card is not relevant, as it only affects the performance and availability of the replication network.

Q136. What is a feature of Dell EMC UnityVSA systems?

Synchronous replication

Data at Rest Encryption

Dynamic storage pools

Traditional storage pools

Q137. A system administrator is configuring asynchronous remote replication for an existing NAS server and its’ file systems on a Unity system.
What should the administrator create to ensure all data is replicated for the NAS server and the file system?

Replication sessions on each file system only

Replication sessions for each file system first and then the NAS server

A replication session on the NAS server and then manually create replication sessions on each file system

A replication session for only the NAS server

Q138. A storage administrator has a Dell Unity XT 480 system with one pool of flash drives, 192 GB of RAM, and
1.2 TB of FAST Cache.
What is the total cache availability for caching the flash drives?

3.2 TB

1.39 TB

3.58 TB

I6.0 TB

Explanation
The total cache availability for caching the flash drives on a Dell Unity XT 480 system with one pool of flash drives, 192 GB of RAM, and 1.2 TB of FAST Cache is 3.58 TB. This is calculated by adding the system memory (RAM), the FAST Cache, and the pool cache. The system memory is 192 GB, which is equivalent to
0.18 TB. The FAST Cache is 1.2 TB, which is a dedicated cache for the flash drives. The pool cache is 2.2 TB, which is a portion of the flash drives that is reserved for caching the pool data. Therefore, the total cache availability is 0.18 + 1.2 + 2.2 = 3.58 TB.
