Question 1
Your client has a block-based storage virtualization environment. They want to avoid losing data in the event of double disk failure.
Which technology do you suggest they deploy?
Which technology do you suggest they deploy?
Correct Answer: C
Question 2
Which solution would address your requirement to encrypt data that will be stored in several SAN-attached storage systems, including both disk arrays and tape libraries?
Correct Answer: C
Question 3
A small law firm that does not currently have any virtualization technologies implemented has recently merged with another firm of approximately the same size.
They are planning to consolidate into a single location. They have decided to virtualize their servers, and they would like to consolidate storage. The current storage utilization is below 60%.
The budget will not allow them to purchase an array that matches the capacity of the current storage. However, they cannot justify the application disruption associated with growing storage over time to meet forecasted capacity requirements.
Which array feature would meet their requirements?
