• A.Array Replication Group
• B.SRDF Physical Relationship
• C.Composite Group
• D.SRDF Logical Relationship

You are designing an SRDF/S solution. Network bandwidth can be purchased in increments of single OC1 (52 Mb/s) links. Data compression is not in use. The workload profile is as follows:
Total I/Os per second = 30,000 Read block size = 4 KB Write block size = 4 KB Writes = 30%
How many OC1 links will provide sufficient bandwidth?

• A.6
• B.1
• C.2
• D.4

What is the effect of SRDF/A enhancedgroup-level pacing on a VMAX3?

• A.I/O on all host LUNs are throttled on the array.
• B.Host I/Os are sent as they are received.
• C.DSE pool is marked for data offload.
• D.Host-issued write I/Os are throttled for the group.

A storage administrator needs to add three newly created RDF devices into an already existing asynchronous SRDF group. What are the appropriate steps to achieve this goal?

• A.Synchronize the three new devices in a temporary group.
  Suspend the temporary group.
  Move the three new devices into the active SRDF/A group with the Consistency attribute.
• B.Move the three new devices into the active SRDF/A group.
  Establish the three new devices.
  Resume the previously active SRDF/A group.
• C.Synchronize the three new devices in a temporary group.
  Suspend the temporary group.
  Move the three new devices into the active SRDF/A group with the Consistency Exempt
  attribute.
• D.Suspend the active SRDF/A group.
  Move the three new devices into the active SRDF/A group.
  Resume the previously active SRDF/A group.
