5.When a remove replication operation is performed on a Dell EMC PowerStore array, what happens
to the destination storage resource?
A. Is deleted
B. Stays in read/write mode
C. Stays in read-only mode
D. Taken offline
Answer: C
Explanation:
"Removing a replication session is initiated on the source system by removing the protection policy
from the Volume or Volume Group on the source system. Removing the protection policy from a
storage resource results in the following: *. The destination storage resource stays in read-only
mode."

Answer: B
Explanation:
Assisted migration - In the background, the system periodically monitors storage resource utilization
across the appliances. Migration recommendations are generated based on factors such as drive
wear, appliance capacity, and health. If you accept a migration recommendation, a migration session
gets automatically created.

A. A 6x 15 TB drives in the 3000T and 6x 15 TB drives in the 9000T both requiring upgrades in six
drive increments
B. 6x 15 TB drives in the 3000T and 12x 7 TB drives in the 9000T both supporting single drive
upgrades
C. 6x 15 TB drives in the 3000T and 6x 15 TB drives in the 9000T both supporting single drive
upgrades
D. 12x 7 TB drives in the 3000T and 6x 15 TB drives in the 9000T both requiring upgrades in six drive
increments
