CAS-002 Question #261: Real Exam Question with Answer & Explanation

The correct answer is B: Enable deduplication on the storage pools. Storage-based data deduplication reduces the amount of storage needed for a given set of files. It is most effective in applications where many copies of very similar or even identical data are stored on a single disk. It is common for multiple copies of files to exist on a SAN.

Question

Options

AEnable multipath to increase availability
BEnable deduplication on the storage pools
CImplement snapshots to reduce virtual disk size
DImplement replication to offsite datacenter

Explanation

Storage-based data deduplication reduces the amount of storage needed for a given set of files. It is most effective in applications where many copies of very similar or even identical data are stored on a single disk. It is common for multiple copies of files to exist on a SAN. By eliminating (deduplicating) repeated copies of the files, we can reduce the disk space used on the existing SAN. This solution is a cost effective alternative to buying a new SAN.
