Question 3

SRDF/A has been enabled between two VMAX3 arrays. What is the benefit of SRDF/A Multi-Cycle mode?

A. Cycle switches will occur even if transmit delta set is not empty B. Transmit cycle will be added to the receive queue C. Data sent across the SRDF link will be larger in size D. R2 side will have two delta sets; transmit and receive

Correct Answer: A

Question 4

What is the benefit of the Link Capacity Adjustment Scheme in an SRDF deployment over a SONET circuit?

A. Enables low capacity circuits to be grouped together into a higher capacity link B. Allows multiple wavelengths of data to be transmitted over the same circuit C. Enables dynamic scaling of bandwidth based on requirements D. Allows the replication throughput to scale linearly based on the TCP connections

Correct Answer: C

Question 5
