Question 1

On a Dell Unity XT file system asynchronous replication session, how many system Snapshots are required to support replication?

Answer : A

On a Dell Unity XT file system asynchronous replication session, four system Snapshots are required to support replication. Two system Snapshots are created on the source file system, and two system Snapshots are created on the destination file system. The source system Snapshots are used to track the changes that need to be replicated, and the destination system Snapshots are used to apply the changes and maintain a consistent point-in-time copy of the source data. The system Snapshots are automatically created and managed by the replication engine and are not visible to the user.

Question 2

On physical Dell Unity XT models, which storage feature can only be configured from UEMCLI or Rest API?

ACreating Dynamic Pools

BEnabling SSH

CConfiguring and monitoring the system

DCreating Traditional Storage Pools

Answer : C

Question 3

Which feature can be configured for a Dell Unity XT file system NFS share?

AAccess-Based Enumeration

BProtocol Encryption

CHost Access Level

DDistributed File System

Answer : C

A feature that can be configured for a Dell Unity XT file system NFS share is the Host Access Level. This feature allows the user to specify the access permissions for each host or host group that is allowed to access the NFS share. The access permissions can be set to Read/Write, Read Only, or No Access. The Host Access Level feature can be used to control the security and performance of the NFS share. Access-Based Enumeration, Protocol Encryption, and Distributed File System are features that can be configured for a Dell Unity XT file system SMB share, not NFS share.

Question 4

Which disk format is recommended when deploying Dell UnityVSA OVA?

AThin Provision

BThick Provision Lazy Zeroed

CThick Provision Eager Zeroed

Answer : C

When deploying Dell UnityVSA OVA, the recommended disk format is Thick Provision Eager Zeroed, which allocates and zeroes out all the space for the virtual disks at the time of creation. This ensures better performance and avoids potential issues with thin provisioning on the underlying storage. Thin Provision and Thick Provision Lazy Zeroed are not recommended, as they may cause performance degradation and unexpected out-of-space errors.

Question 5

A company needs to expand their dynamic pool by 10 TB. The current dynamic pool consists of 63 7.6 TB SSD drives that are configured for RAID 5 (12+1).

What is the minimum number of drives needed for the pool expansion?

B15

C13

Answer : C

To expand a dynamic pool, the number of drives added must be equal to or greater than the stripe width of the pool. The stripe width is the number of data drives plus the number of parity drives in a RAID group. In this case, the stripe width is 12 + 1 = 13.Therefore, the minimum number of drives needed for the pool expansion is 13.Reference: Dell EMC Unity: Dynamic Pools Technical White Paper1, page 8.

Question 6

Which is the preferred FC Port for synchronous replication for a Dell Unity XT 380 system?

AFibre Channel Port 0 of I/O module 0

BFibre Channel Port 4 of SPA and SPB www*

CPort 0 of I/O module 1

DPort 1 of I/O module 0

Answer : B

The preferred FC Port for synchronous replication for a Dell Unity XT 380 system is Fibre Channel Port 4 of SPA and SPB. This port is dedicated for synchronous replication traffic and has the highest priority and bandwidth allocation. Synchronous replication is a method of replicating data between two Dell Unity systems with zero recovery point objective (RPO). It requires a low-latency and high-bandwidth network connection between the source and destination systems.

Question 7

A deployment engineer creates a file system to test File Level Retention Compliance (FLR-C). After testing the feature, they are unable to delete the file system.

What is causing this issue?

AIndividuals with an administrative role cannot delete FLR-C file systems that contain locked files.

BThe engineer must delete all locked files before the file system can be deleted.

CThe engineer must use the security admin role to delete the FLR-C enabled file system.

DThe FLR-C option must be changed to FLR-E before the file system can be deleted.
