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
Refer to exhibit.

SRDF device pairs are suspended by the administrator.
Which symrdf command was issued next?
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.

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