정답: A
A storage administrator is planning to implement Dynamic Cache Partitioning (DCP) on an EMC Symmetrix VMAX array. There are five applications running on hosts attached to this array. The administrator wants to ensure that none of these applications have any effect on each other due to cache conflicts.
Which steps need to be completed to configure DCP?
Which steps need to be completed to configure DCP?
정답: D
A server providing streaming video to clients is configured with storage from an EMC Symmetrix VMAX array. The data on this server is static and does not change. The file system for the videos is on a 600 GB striped metavolume made up from 8 x 75 GB standard RAID 5 devices.
The storage administrator is baselining the performance of the system using Performance Manager. The administrator notices that the "seq reads per sec" metric is much lower than expected for a heavy sequential read application.
What is the most likely reason for this situation?

정답: B
Storage administrators for a Symmetrix running Enginuity 5773 need to increase allocated storage for Microsoft Exchange LUNs without interrupting the mail server's operation. Performing a protected striped LUN expansion causes a critical nightly clone operation to run for hours instead of minutes. This impacts later dependent jobs, preventing production operations from completing.
How can this impact to the nightly process be prevented?
How can this impact to the nightly process be prevented?
정답: C
Storage from an EMC Symmetrix VMAX array has been presented to a number of ESXi servers. The number of LUNs seen by any ESXi server is less than 30 and the LUN numbers are consecutive.
