Refer to the Exhibit.

A company has three data centers and has decided to protect its data using SRDF.
The replication design must ensure there will be no data loss if Site A fails.
All data centers are within 200 km of each other.
Either Site B or Site C should be able to take over as production sites in the event of the failure of Site A.
SRDF/S is used between Sites A and B.
How should SRDF be configured between Sites B and C?

• A.Disk-less R21 devices with SRDF/A between Sites B and C
• B.Disk-less R21 devices with SRDF/S between Sites B and C
• C.Disk-based R21 devices with SRDF/S between Sites B and C
• D.Disk-based R21 devices with SRDF/A between Sites B and C

A company is planning to deploy Enterprise Flash Drives (EFDs) in their EMC Symmetrix VMAX array.
When using devices on the EFDs, which I/O profile will benefit the most?

• A.Sequential writes
• B.Sequential reads
• C.High random writes
• D.High random reads

A storage administrator is configuring Optimizer on an EMC Symmetrix VMAX array. The array is configured entirely with RAID 5 (3+1) devices. All devices are 8 GB and all devices are R1 devices with SRDF/A mirrors on a remote array.
Optimizer has completed the first cycle of performance analysis and has recommended a large number of device swaps to balance the activity on the array. The storage administrator has been asked to minimize the time it takes to complete all the swaps.
What is the minimum number of DRV devices that the administrator needs to configure?

• A.4
• B.32
• C.8
• D.16

A company currently has a PowerPath-enabled SAN environment with many hosts. A majority of the hosts have storage allocated from Fibre Channel drives and have poor service time. They intend to design a solution for Symmetrix VMAX storage consolidation to replace their current storage infrastructure.
What is a key design guideline to overcome this issue?

• A.Configure devices to evenly distribute the workload
• B.Change PowerPath policy
• C.Acquire faster ports
• D.Implement dynamic cache partitioning

A company uses VMware ESXi servers and EMC Symmetrix VMAX storage arrays. The storage administrators use the VMware vSphere client on their Microsoft Windows desktops to manage the environment. They would like to use the EMC Virtual Storage Integrator Path Management plug-in.
Which path management activities will this plug-in allow?

• A.Change the multi-pathing ownership of all Symmetrix devices from NMP to PowerPath/VE
• B.Set multi-pathing policy for individual Symmetrix devices
• C.Change the multi-pathing ownership of individual Symmetrix devices from NMP to PowerPath/VE
• D.Set multi-pathing policy for all Symmetrix devices
