In addition to encryption, which solution would allow you to do this in a secure and automated fashion?
A) Use a manual record deletion solution.
B) Physically destroy hard drives holding the data
C) Store data indefinitely.
D) Use the key management solution.

Accepted Answer

A key management solution allows you to manage encryption keys, including revoking access by deleting or disabling keys, thus preventing access to the encrypted data.

Question 12

Five out of 4S servers using one particular enterprise storage system are experiencing performance degradation during normal working hours. All 48 servers have similar workload characteristics. There are multiple disk groups that make up your enterprise storage. What should be monitored to determine the root cause?
A) IOPS per RAID array
B) Cache read hit ratio
C) Traffic levels on the SAN switches
D) Clone sessions
