During this time period, the Microsoft Exchange administrators report that archiving operations come to a halt. Neither operation can be moved to a different time due to other dependencies. How can performance be improved for the Exchange team without impacting the database data import?

B.    Use Dynamic Cache Partitioning with a large static partition and a low write pending limit.
C.    Apply Quality of Service parameters for copy pacing on the database volumes.
D.    Increase the number of HBAs in the Exchange server for more bandwidth.

Answer: A

Microsoft Exchange has been virtualized to a production ESXi server managed by VMware vCenter. Replication Manager is being used to replicate LUNs containing the Exchange VMFS to a testing ESXi server. The LUNs are successfully replicated and mounted to the testing ESXi server, but the VMFS is not visible. What could be the cause?

A.    LVM Resignature switch must be enabled to write a new signature to the LUNs.
B.    Replication Manager proxy host has not been registered with vCenter.
C.    Replication Manager proxy host does not have the vCenter management credentials.
D.    TCP port 443 has not been opened between the production server and the testing server.

The server is running a database application with database tables located in a file system on a 100 GB standard device. Performance Manager shows that during peak activity times, the 100 GB device is reaching its device write pending limit. Which solution may help resolve this performance issue?

A.    Migrate to 4 x 25 GB devices and configure a striped volume using a host-based LVM.
B.    Migrate the database file system to a larger standard device to increase its write pending limit.
C.    Add cache to the array to increase the system write pending limit.
D.    Increase the device write pending limit for the existing standard device.
