Question 1

A user can create, manage, and delete PowerMax SRDF device pairs. They can also view the array information, masking objects, device information, and the defined RBAC rules. However, they are unable to create and delete SRDF groups.

Which RBAC profile has been assigned to the user's profile?



Answer : C

The user has been assigned the RemoteRep role only.The RemoteRep role allows users to create, manage, and delete SRDF device pairs, as well as view array information, masking objects, device information, and RBAC rules2. However, it does not allow users to create and delete SRDF groups, which requires the StorageAdmin role. Therefore, answer C is correct.

A, B, and D are incorrect because they do not match the user's profile.SecurityAdmin (A) role allows users to manage security settings such as authentication methods, certificates, RBAC rules, and audit logs2.Auditor (B) role allows users to view array information and audit logs only2.LocalRep (D) role allows users to create, manage, and delete TimeFinder SnapVX sessions from a source device2. None of these roles allow users to create and delete SRDF device pairs.


Question 2

Refer to exhibit.

Refer to the exhibit.

SRDF device pairs are suspended by the administrator.

Which symrdf command was issued next?



Answer : C

The symrdf split command is used to suspend SRDF/A replication and make both R1 and R2 devices read/write enabled. This is useful for testing purposes or for creating point-in-time copies of data on both sides. The symrdf establish command can be used to resume SRDF/A replication after a split operation.The exhibit shows that both R1 and R2 devices are read/write enabled and have a Split status, which indicates that a symrdf split command was issued next2


Question 3

Which metrics are recommended to start analyzing the overall efficiency of the array due to cache?



Answer : D

The metrics that are recommended to start analyzing the overall efficiency of the array due to cache are array-level % Hit and % Cache WP. The array-level % Hit metric shows the percentage of read requests that are satisfied from the cache memory, without accessing the physical disks. A high % Hit value indicates that the cache is effective in reducing the read latency and improving the performance. The % Cache WP metric shows the percentage of cache memory that is occupied by write pending data, which is data that has been written to the cache but not yet destaged to the physical disks. A high % Cache WP value indicates that the cache is under pressure and may not have enough space to accommodate new write requests, which can lead to performance degradation. By monitoring these two metrics, a storage administrator can evaluate the overall efficiency of the array due to cache and identify any potential issues or bottlenecks.

Question 4

Refer to the exhibit.

What should be done first to recover from this Concurrent SRDF/Star configuration failure?



Answer : A

In a Concurrent SRDF/Star configuration failure, the first step to recover is to switch to the 1st Target Site. This is because in a Concurrent SRDF/Star configuration, there are two target sites and one source site.If there's a failure, the source site can switch to either of the target sites based on the business continuity plan1.Reference:Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide


Question 5

SRDF/Metro has been implemented with the bias setting. The R1 side of the pair is configured as the bias side.

How does the device bias work with the R2 device if the R1 array has a failure?



Answer : D

In an SRDF/Metro configuration with bias setting, if there is a failure at the R1 array (which is configured as the bias side), the R2 device automatically becomes the active device. This means that even if there's a failure on the R1 side, operations can continue on the R2 side without interruption, ensuring high availability.

Question 6

A DG group is part of a snapshot schedule which runs each day at 9 am then linked to a set of targets for a full copy after termination. Additional volumes were added which increased the link to full copy time.

What course of action will prevent the issue?



Answer : B

The-precopyoption in therelinkcommand can be used when you want to start copying data to the target devices immediately after the link operation. This can be useful in situations where additional volumes have been added, increasing the link to full copy time. By using-precopy, you ensure that the data starts copying immediately, preventing potential issues.


Question 7

A disaster occurred at the workload site of an SRDF/Star configuration. The administrator decides to move the workload to the Synchronous site (Site B).

What symstar command should be used before the workload switch?



Answer : B

The symstar halt command is used to write disable devices and synchronize SRDF data to remote sites in an SRDF/Star configuration. This command ensures that all sites have a consistent copy of data before switching the workload site from one site to another.Therefore, the symstar halt command should be used before the workload switch in case of a disaster at the workload site of an SRDF/Star configuration1
