Which configuration option best meets the data storage requirements?

Your task is to configure storage for an Oracle Solaris 11 system to support multiple web servers.
Each web server will be contained in a separate zone. The system has an attached disk array
configured as a JBOD (Just a Bunch Of Disks). The system also has an internal solid-state drive.
The data accessed through the websites will be primarily read-only. The web servers are expected
to be very busy, so configure the storage for maximum performance. Because the data is primarily
static, but redundancy is required to maintain high availability in the event of a hardware failure.
Data does not change often, but it is expected that the same data will be accessed many times
throughout the day.
Which configuration option best meets the data storage requirements?

A.
a raid2 storage pool with a separate log device

B.
a mirrored storage pool with a separate cache device

C.
a mirrored storage pool with a separate log device

D.
a three disk striped storage pool with a separate cache device

E.
a raidz1 storage pool with a separate log and cache device

Explanation:
Required to maintain high availability –> use a mirror.
The same data will be accessed many times throughout the day. Configure the storage for
maximum performance. Use caching.
