You have designed a VNX for File implementation for a customer data environment that involves a high level of data duplication. The customer is concerned with disk efficiency, and you have designed the system with the minimum number of
disks necessary to meet expected storage needs after deduplication.
The customer is initially pleased with the implementation. The decision is made to add a cycle of SnapSure Checkpoints for backup and recovery purposes. Within weeks, deduplication automatically aborts.
What would you recommend to get deduplication working again?
A. Disable SnapSure auto-extension and manually manage SavVols
B. Decrease the auto-extension high watermark to 50%
C. Use more, smaller Checkpoints
D. Change the quota policy to file size
Your customer would like to replicate their Oracle database between their two data centers. The data centers are located approximately 1500 km apart. Which array-based solution is best suited to replicate their database?
A. MirrorView/A
B. MirrorView/S
C. SnapView
D. DataGuard
Replication Manager (RM) is being used to create replicas for a SQL server installed on VMFS residing on an ESX server. The operations are sent from a separate virtual RM proxy host. However, the RM is not able to successfully create copies.
What is the most likely cause of the failure?
A. The RM proxy host is not registered with the RM server.
B. The RM proxy is not a physical host.
C. The RM server is unable to communicate with the RM proxy over port 445.
D. The RM server credentials were not properly entered for the RM proxy.
Analyzer indicates that a LUN has a Queue Length of 2.3 and an Average Busy Queue Length of 5.1, and that Average Seek Distance is 25 GiB for the 300 GB disks used in the RAID Group. Based only on these findings, which statement is true?
A. No definite conclusion can be made about randomness
B. LUN reads are random
C. LUN writes are random
D. LUN randomness is dependent on disk randomness
Your customer has a VNX array with FAST Cache licensed and two storage pools created. Only Storage Pool A has FAST Cache enabled.
They currently use both Storage Pools for their general production environment, but would like you to design an environment that will support their Exchange 2010 deployment. There is sufficient free space in both Storage Pools to
accommodate their Exchange storage requirements.
Based on EMC best practice guidelines, which design would you recommend?
A. Create database volumes on Storage Pool A. Create log volumes on Storage Pool B.
B. Create database and log volumes on Storage Pool A.
C. Create database volumes on Storage Pool B. Create log volumes on Storage Pool A.
D. Create database and log volumes on Storage Pool B.
Your customer has a VNX array with FAST Cache licensed with a single storage pool created.
They currently use the Storage Pool for their general production environment, but would like you to design an environment that will support their Exchange 2010 deployment. There is sufficient free space in the Storage Pool to accommodate
their Exchange storage requirements.
Based on EMC best practice guidelines, which design would you recommend?
A. Enable FAST Cache on the existing Storage Pool. Place the database volumes on the existing Storage Pool. Create a second storage pool for the log volumes.
B. Place the database and log files on the existing Storage Pool. Enable FAST VP. Increase the array Write Cache value.
C. Create a new Storage Pool. Place the database and log files on this new Storage Pool. Enable FAST VP.
D. Enable FAST Cache on the existing Storage Pool. Place the log volumes on the existing Storage Pool. Create a second storage pool for the database volumes.
A VNX for File administrator using SnapSure has created a recurring monthly cycle of Checkpoints. The administrator has been tasked with changing this to a weekly cycle by deleting a number of checkpoints. What would you recommend to minimize performance impact?
A. Delete the checkpoints during a period of low client activity.
B. Delete the newest checkpoints first.
C. Extend the SavVol by 50% before deleting the checkpoints.
D. The PFS must be unmounted during checkpoint deletion.
You are in a design session with a customer of an ESXi 5.0 cluster. One of the stakeholders inquires about vNUMA. By default, what is the minimum number of CPUs in a vNUMA enabled environment?
A. More than 4 vCPU
B. More than 8 vCPU
C. More than 12 vCPU
D. More than 16 vCPU
Exchange 2010 is being virtualized on a VNX storage array in a VMware environment. Array- based replicas will be used to provide data protection. Which best practice should be followed to increase performance and reduce the meta data activity on the VMFS volume?
A. Enable Independent disk, Persistent mode.
B. Dynamically grow VMDK files as needed to save space and prevent fragmentation.
C. Deploy Lazy Zero disks to rapidly allocate space as needed.
D. Enable Independent disk, Nonpersistent mode.
Which tool provides recommendations on how query processing performance can be improved by modifying physical design structures such as indexes, indexed views, and partitioning?
A. Tuning Advisor
B. Query Editor
C. SQL Activity Monitor
D. Performance Monitor
