A proposed SRDF/S solution was modeled with BCSD. The model assumed that the Source array had 2 RFs.
The RA utilization chart shows the maximum utilization at 80%. How many RFs should be recommended to ensure a successful implementation?

• A.2
• B.3
• C.6
• D.4

Refer to the exhibit.

You have used BCSD to model an SRDF/A solution. Based on the SRDF/A risk analysis shown what are your recommendations?

• A.Provide more bandwidth and more remote adapters. Upgrade both arrays to Symmetrix VMAX.
• B.Ensure that the SRDF devices on the source and target arrays use the same protection and reside on disks with the same RPM. Provide more remote adapters.
• C.Provide more bandwidth. Upgrade both arrays to Symmetrix VMAX.
• D.Ensure that the SRDF devices on the source and target arrays use the same protection and reside on disks with the same RPM. Upgrade both arrays to Symmetrix VMAX.

A proposed SRDF/S solution was modeled with BCSD using host-based data. The BCSD model assumed two-engine VMAX arrays with SRDF Fibre ports. The RA Utilization chart
shows a maximum utilization of 45%. The Volume Exceptions table lists five devices.
What should be recommended?

• A.Turn on software compression on the remote adapters
• B.Use three-engine VMAX arrays
• C.Change the application layout
• D.Add more remote adapters

What is a supported mode combination for disk-based Cascaded SRDF?

• A.First leg - SRDF/S Second leg - SRDF/S
• B.First leg - SRDF/A Second leg - SRDF/A
• C.First leg - SRDF/S Second leg - SRDF/A
• D.First leg - SRDF/S Second leg - SRDF Adaptive Copy Write Pending Mode

A customer needs to configure SRDF/S between two sites 10 km apart. The customer
connected the R1 ports to fabric-A at site 1 and the R2 ports to fabric-B at site 2. The customer does not want to merge the two fabrics between sites.
What is the recommended solution?

• A.Connect the RDF ports using DWDM or SONET.
• B.Implement FCIP connection to isolate the fabric
• C.Implement FC routing or Virtual SAN to isolate the fabric
• D.Merge two fabrics, and zone R1 and R2 ports.
