A customer plans to replicate an Oracle instance to an EMC VNX located in their test environment. What Oracle files are required to be replicated to ensure that the database will start up?

• A.data files, archive log files, pfile
• B.control files, spfile, data files
• C.control files, data files, redo log files
• D.data files, control files, archive log files

A customer runs Oracle using DAS. They observe intermittent Oracle performance degradation due to data hot spots on the disks. You propose they move Oracle to an EMC VNX with RAID 1/0 LUNs. If the customer implements the proposed configuration, how would Oracle ASM alleviate the customer's hot spots?

• A.The Unisphere Agent installed on the Oracle server will re-balance all existing Oracle objects automatically.
• B.ASM will re-stripe the data avoiding the target MirrorView volume hot spots.
• C.The ASM disk group will re-balance all existing Oracle objects automatically.
• D.ASM with Unisphere will re-stripe the data avoiding the source MirrorView volume hot spots.

A financial company plans to implement an EMC VNX for several application servers. The application servers run high performance data mining processes for large databases and reporting. The customer requires a storage configuration that balances performance and cost.
Which disk RAID type will best meet the customer requirements?

• A.RAID 1/0
• B.RAID 5
• C.RAID 3
• D.RAID 6

A customer wants to migrate a LUN from one EMC VNX to another. The customer wants to use the integrated LUN migration feature. Due to a change freeze, the customer can install additional software, but cannot add any additional hardware. What do you recommend?

• A.Configure Thin source LUNs and Thick target LUNs
• B.Use SAN Copy, rather than LUN migration
• C.Use RecoverPoint, rather than LUN migration
• D.Configure target LUNs 20% larger than source LUNS

A heterogeneous Pool is created as follows:
5 x 200 GB FAST VP optimized Flash drives, configured as 4+1 R5 10 x 600 GB 10K rpm SAS drives, configured as 4+1 R5 16 x 2 TB NL-SAS drives, configured as 6+2 R6
Ten equal-sized thick LUNs are created on the pool at 5 minute intervals. No space is left in the pool. All parameters are left at the default value. Testing is started at 9:00 AM on the 10 LUNs using IOmeter. The R/W ratio for the testing is set at 3:1, and 4 kB random I/Os are performed.
What throughput should you expect to see from the LUN that was created first?

• A.10,400 IOPS
• B.3,500 IOPS
• C.18,200 IOPS
• D.5,000 IOPS
