When setting up an AVM created file system, the storage administrator set the "is_greedy" option. When they look at the underlying structure of the newly created file system, they notice the file system is sliced. What is the reason for this behavior?

• A.A slice is created by default, then a metavolume is placed on top of the slice for the file system ignoring the "is_greedy" option.
• B.User defined pools do not use the "is_greedy" option.
• C.Auto extend option is supported with mapped pools, but only with non-greedy AVM-created file systems.
• D.The "is_greedy" option is ignored on mapped pools.

You are implementing a VNX solution for a Linux-only host environment. The customer tells you that current host performance is poor, and that the new solution should improve it by at least 50%.
Which tool should you use to begin your investigation?

• A.iostat
• B.Unisphere Analyzer
• C.IOmeter
• D.server_stats

A customer has two sites, with a VNX system at each site. The local site has four application LUNs of 256 GB each. They are replicated to the remote site with MirrorView/S. The linkbetween the sites has an effective bandwidth of 100 MB/s. The application generates 800 random IOPS of 8 kB with a 3:1 R/W ratio on each of the LUNs. The link fails for 15 minutes.
How much data is copied to the secondary LUNs as part of the resynchronization process?

• A.1.4 GB
• B.44 GB
• C.88 GB
• D.22 GB

A customer wants to implement file system replication between two EMC VNX systems. The source production file system contains data from a sequential workload that resides in a pool composed of NL-SAS drives.
The destination file system will be configured with a SnapSure schedule for data sharing. Due to cost concerns, the destination file system and SavVol volumes will also be placed on NL-SAS.
What should you tell the customer about this configuration?

• A.NL-SAS is adequate if the source file system is on NL-SAS and contains a random application.
• B.Replicator session performance will decrease because of destination file system checkpoint reads.
• C.The destination file system can be used as a source for cascaded replication with no impact to performance.
• D.Only Flash and SAS drives should be used for Replicator SavVol volumes.

A Storage Administrator would like to use Manual Volume Management to create file systems for their Oracle database log files.
Which volume configuration is suitable for storing log information?

• A.disk > stripe > slice > meta
• B.disk > meta
• C.disk > slice > stripe > meta
• D.disk > stripe > meta
