QUESTION: 13

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?

Set copy to URGENT
Relink with the -precopy option
Set copy pace 16
Relink without the -copy option

Answer(s): B

Explanation:

The -precopy option in the relink command 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: 14

A company has two PowerMax arrays located 100 km apart. The arrays are configured with SRDF/S

over Fibre Channel.
Which Dell EMC technology improves FC replication between sites?

Fast Write
SIRT
Write Acceleration
Deduplication

Answer(s): A

Explanation:

Fast Write is a Dell EMC technology that improves Fibre Channel (FC) replication between sites in a SRDF/S configuration.
When a write I/O is issued by the host to the R1 device, SRDF with Fast Write acknowledges the write to the host as soon as the data is stored in the R1's cache and transmitted to the R2's cache. This results in reduced latency and improved performance for FC replication between sites.

QUESTION: 15

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?

Device bias is unable to make the R2 device available to the host
Device bias performs a half-swap, and the R2 device becomes the new R1 device
R2 device automatically becomes the bias device
R2 device automatically becomes the active device

Answer(s): D

Explanation:

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.
