• C. A dependent-write consistent copy is maintained between the R1 and R2 devices.
• D. Devices that have the Consistency Exempt attribute set can be controlled independently of the other devices.

Question 5

DRAG DROP

Match each item with its description.

performance.
What is a consideration?

• A. Both V-Bricks must contain 1 TB of cache each
• B. RAID type of both V-Bricks must be the same
• C. Cache size of both V-Bricks must be equal
• D. Number of drives must be less than or equal to 96

Question 11

DRAG DROP

has completed the tasks for the local side of the solution, including RA Port Group, Replication
Group, and site switch.
What is the correct order of steps the architect needs to take to complete the SRDF setup?
