Your customer is designing a Proof of Concept with SQL Server attached to a VNX. The storage design includes seven LUNs on a RAID Group. The system is generally very heavily loaded, with a particularly high load on the cache. This is a very carefully controlled environment and your customer has asked for assistance in planning the layout of the LUN location on the physical spindles.
Where in the RAID Group would you recommend placing the two heavily used LUNs if the physical spindle is fully utilized?

• A.One at beginning and one at the end
• B.Evenly placed, as non-adjacent as possible
• C.Adjacent to each other in the middle
• D.Adjacent to each other at the beginning

A SQL Data Warehouse database is replicating between two VNX storage systems with Incremental San Copy. The production database is on 15, 15k rpm SAS drives and the Reserved LUN Pool uses five NL-SAS drives. The database is continuously updated locally and replicated once a day to maximize the benefits of write folding. Replication takes place from 6 PM until 10 PM. At 6 PM the storage administrator notices an increase in response time of the application, which steadily improves until 10 PM.
What should be done to improve performance during replication without affecting recovery data granularity?

• A.Create a clone of the source volume and replicate the clone.
• B.Adjust the San Copy throttle to minimize the impact to the production application.
• C.Expand the number of drives in the source volume to accommodate the increased I/O from the replication session.
• D.Put the Reserve LUN Pool on a similar disk and RAID type as the source volume.

Refer to the exhibit.

A pre-MCx VNX has three SAS DAEs configured with eight 4+1 RAID 5 Groups and six Hot Spares as shown in the exhibit. All RGs are unused except for RG 0, which contains the Control LUNs. All LUNs except for those in RG 0 are the same size.
Which dvols will be selected for file system creation using Automatic Volume Management System-defined pools?

• A.dvols 11, 13, 20, and 22
• B.dvols 9, 10, 11, and 12
• C.dvols 7, 11, 17, and 25
• D.dvols 9, 12, 14, and 18

A VMware 5 customer is planning to upgrade their networking environment to 10 Gb Ethernet. They would also like to use real time vMotion to ensure balanced application load distribution throughout their environment. They are also currently running their VMware environment on 64bit, dual core processors.
What advice would you give to your customer to assist them with the upgrade of their environment?

• A.Upgrade their servers to quad core CPUs or greater and ensure all servers have access to the datastores.
• B.Ensure all servers have multiple paths to all arrays to support VM file movement and all VMs are configured for HA.
• C.Ensure that all vMotion sessions are configured for core 0 (zero) affinity and enable Direct Path I/O.
• D.Configure NIC teaming on their servers and ensure that all VMs on each ESXi server are configured for FT.

A customer is supporting 800 Exchange users on a VNX5700. The users are divided among four Exchange storage groups using a total of eight LUNs each for data and logs and two LUNs for a cluster quorum disk and MSDTC. The company purchased a VNX5300 for its remote site. The company is using MirrorView/A with consistency groups to ensure consistent point-in-time recovery. The Exchange LUNs have been added to the consistency group, but the administrator is having trouble adding the quorum and DTC LUNs.
What should the administrator do?

• A.Fracture all mirrors before adding them to the consistency group
• B.Create a second consistency group for the quorum and DTC LUNs
• C.Create ten consistency groups (one for each LUN) and ensure that the update frequency is the same for all groups
• D.Evenly distribute all LUNs across both SPs before adding them to the consistency group
