When using Timefinder/SNAP, what is true of Save devices?
A. RAID6 is the preferred protection for Save devices.
B. Save devices store the original track from the source device which is copied on first access.
C. Each Save device is recommended to be equal to or less than the largest VDEV.
D. RPQ is required to use RAID1 protection on Save devices.
A customer is migrating from a DMX to a VMAX. To minimize the outage window Open Replicator hot pull has been selected to perform the migration. Which Open Replicator license is required and which array should it be applied to?
A. Open Replicator/LM on the VMAX.
B. Open Replicator/LM on the DMX.
C. Open Replicator/DM on the VMAX.
D. Open Replicator/DM on the DMX.
A Symmetrix Customer has an application that runs 24 hours a day, 7 days a week and 365 days a year.
They would like to replicate the application data simultaneously to four branch offices on a nightly basis.
The branch offices have EMC VNX arrays.
Which solution would you recommend?
A. Use TimeFinder/Clone to replicate the production application. Then use Open Replicator cold push to replicate the clones.
B. Use Open Replicator cold push to replicate the production devices
C. Use Open Replicator hot push to replicate the production devices.
D. Use TimeFinder/Snap to replicate the production application. Then use Open Replicator hot push to replicate the VDEVs.
You are designing a Symmetrix VMAX SRDF/S over Fibre Channel solution. The production and remote data centers are 50 kilometers apart. What is the expected write response time delay due to latency?
A. 0.5 ms
B. 0.25 ms
C. 1 ms
D. 2 ms
A colleague implemented cascaded SRDF for a VMAX technology refresh and site relocation activity.
The colleague reports they shutdown the hosts at production Site A and copied all data to the bunker Site
B VMAX. But they are unable to enable SRDF/S between Site B and remote Site C.
What should you advise them?
A. SRDF/S is not supported on the second leg of a cascaded SRDF implementation.
B. Enable SRDF/A on the first leg and then enable SRDF/S on the second leg.
C. Suspend SRDF/S on the first leg and then enable SRDF/S on the second leg.
D. The Site B devices must be converted to use concurrent SRDF.
What is a feature of Delta Set Extension pools?
A. An SRDF/A group can be associated with different pools, regardless of protection or emulation type.
B. DSE pools can be shared between multiple SRDF/A groups.
C. DSE Pools are only required at the R1 side.
D. RAID5 with 15krpm disks is recommended for optimal performance of a DSE pool.
What is the EMC recommended network quality for SRDF/S over GigE?
A. Less than 0.01% packet loss
B. Less than 0.1% packet loss
C. Less than 0.25% packet loss
D. Less than 1% packet loss
Your customer is adding a new database application. You are asked to design a solution to expand the current SRDF/S implementation on the customer's two Symmetrix VMAX arrays to account for this growth. As part of the sizing, you notice that the two RA ports are at 85% utilization.
What should you tell your customer that the solution requires?
A. At least two more RAs are required
B. At least one more RA is required
C. No additional hardware is required
D. More memory is required
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 Compressed Throughput chart shows that the available throughput is greater than the peak throughput. The Volume Exceptions table lists ten devices.
What should be recommended?
A. Change the application layout
B. Use three-engine VMAX arrays
C. Provide more bandwidth
D. Turn off software compression on the remote adapters
You need to model several SRDF/A workloads that require data consistency across all the sessions. How would you model the multiple SRDF/A sessions?
A. In BCSD, link them by creating a Composite Group
B. In SymmMerge, link them by creating a Composite Group
C. In BCSD, link them by creating a Logical Relationship
D. In SymmMerge, link them by creating a Logical Relationship
