You are assisting a company with planning a new VMware environment. The hosts will be connected to a VNX array using two HBAs and two Fibre Channel switches. The host initiators will be configured in ALUA mode and will have multiple paths to the VNX.
The customer wants to take advantage of the multiple paths for increased performance. Any trespassed LUNs should be handled without manual intervention from their SAN administrator.
Which multi-pathing solution is a viable option for this company?

• A.PowerPath/VE in ClarOpt mode
• B.VMware NMP in Round Robin mode
• C.PowerPath/VE in SymmOpt mode
• D.VMware NMP in Fixed mode

You have advised your customer to upgrade their current CLARiiON storage array before migrating to a new VNX. The customer would like additional information about what benefits the upgrade will provide.
Where can you find information on known and fixed problems for EMC products?

• A.Simple Support Matrix
• B.Release Notes
• C.E-Lab Navigator
• D.E-Lab Analyzer

An enterprise-level customer has recently implemented a pair of bi-directionally IP replicated VNX systems for their highly transactional CIFS file-based environment and NFS Office systems. Each VNX has two storage pools of Flash RAID 5, SAS RAID 5, and NLSAS RAID 6 for source file systems and SAS. NL-SAS for destination file systems with multiple checkpoints are being taken each day and retained for 30 days.
After a number of months, they have growing concerns that the replication performance has degraded. In addition, the amount of free space available in the source storage pools has beenreduced to almost critical levels. They asked your advice on whether to utilize 16 unassigned NL-SAS drives to extend the pools or to purchase additional SAS drives.
How would you advise the customer about the next step?

• A.Purchase additional SAS drives to increase the performance and pool sizes
• B.Create a new pool from the NL-SAS drives and relocate all SavVols to it
• C.Add 16 x NL-SAS drives to the source pool on each system
• D.Add 8 x NL-SAS drives to the source and destination pools on each system

A customer is interested in the spin-down feature of their new VNX array. However, they cannot get the feature to function. Their current drive configuration consists of a pool of 32, 2 TB NL-SAS drives for their backup-to-disk application.
Why is the spin-down feature failing to run?

• A.Can only be enabled for NL-SAS and SAS drives in pools
• B.Can only be enabled for NL-SAS drives in RAID groups
• C.Can only be enabled for SAS drives in pools
• D.Can be enabled for SAS and NL-SAS drives only in RAID groups

You are reviewing a NAR file and notice that a LUN has a write cache hit ratio of 0.0.
How can you tell if write cache is enabled for the LUN?

• A.Check the SP Properties page.
• B.Check the LUN write-aside value.
• C.Check for forced flushes.
• D.Check for reads satisfied by the read cache.
