EMC Proven Professional – XtremIO Solutions Expert — Question 23

A company is using SRDF/AR Multi-Hop as a disaster recovery solution. Their primary application requires 27.3 TB on their primary site. How much storage capacity is required on the third site?

Answer options

• A. Only 27.3 TB
• B. 27.3 to 54.6 TB
• C. Only 54.6 TB
• D. Greater than 54.6 TB

Correct answer: C

Explanation

The correct answer is C, as SRDF/AR Multi-Hop requires a full copy of the data at the final target site. Since the primary application needs 27.3 TB, the third site must also accommodate the complete data set, which means it requires 54.6 TB to maintain redundancy. Options A and B do not provide sufficient storage, while D exceeds the necessary requirement.
