A VNX customer has a production read-intensive Oracle environment that requires immediate access for end-user reporting. Which EMC replication application meets the customer's business requirement?
A. SnapView Snapshots
B. MirrorView/S
C. Replication Manager
D. MirrorView/A
A customer plans to add a new LUN to a Windows 2003 server. They are aware that LUN disk crossing will affect performance. Which procedure can significantly reduce LUN disk crossings in an SQL environment?
A. Use diskpart to set the disk partition offset to 2048 blocks
B. Use only 4+1 disk sets when configuring RAID 5
C. Use an NTFS cluster size of 64 KB
D. Use striped metaLUNs consisting of exactly four component LUNs
An EMC VNX with FAST Suite will be used as block storage for a mail environment with four Exchange 2010 servers. The Exchange servers will serve as mailbox and archive mailbox servers. The VNX has the following disks in two DAEs:
-Five 200 GB Flash drives
-Fifteen 600 GB SAS drives
-Ten 2 TB NL-SAS drives
What storage pool design will provide balance between performance and storage provisioning?
A. Database pool LUNs should be thin provisioned; log pool LUNs should be thick provisioned.
B. All pools should be provisioned as thick pool LUNs only.
C. All pools should be provisioned as thin pool LUNs only.
D. Database pool LUNs should be thick provisioned; log pool LUNs should be thin provisioned.
An EMC VNX is enabled for FAST Cache using four 200 GB Flash drives. Ten additional Flash drives are available for SQL databases. Which SQL database object would be best suited to utilize these drives?
A. Database components such as tempDB
B. Heavily used log volumes
C. Databases on LUNs with read caching enabled
D. Databases with large, sequential I/O
Six months ago, you implemented an SQL 2008 database and followed EMC best practices for sizing and layout. The database is now experiencing performance slowdowns. You configure Perfmon to capture "disk bytes per second", "average disk queue length", and "percent disk time" in a log view for the database volumes. The log shows the disk bytes per second remained steady but there was an increase in the average disk queue length. Which action should you take to solve this problem?
A. Increase the number of spindles servicing this database.
B. Use SQL Activity Monitor to identify rogue queries that may be affecting performance.
C. Migrate the database to lower latency spindles.
D. Decrease the queue length setting on the HBA.
When creating a clone, what size must the clone be when compared to source LUN?
A. Half the size of the source LUN
B. Same size of the source LUN
C. Two times larger than the source LUN
D. Four times larger than the source LUN
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. The "is_greedy" option is ignored on mapped pools.
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. 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.
A customer is migrating an Oracle database to a new EMC VNX. The database consists of random, small I/O workloads with high transaction rates.
What RAID type should be used for the LUN containing the data files in order to prevent I/O bottlenecks during peak load?
A. RAID 6
B. RAID 3
C. RAID 1/0
D. RAID 5
A customer runs their virtual environment on a cluster of ESX v4.0 hosts connected to an EMC VNX. They report there are long delays when they create large eager-zero thick virtual disks. You recommend they upgrade their virtual environment to vSphere v5.0 to benefit from its VAAI features. Which VAAI primitive addresses their issue?
A. Block Zeroing
B. Hardware assisted locking
C. Full Copy
D. Thin Provisioning Stun
During a host write to an EMC VNX with write cache enabled, at what point does the host receive acknowledgement from the VNX that the write is complete?
A. When the primary storage processor has cached the data
B. When both storage processors have cached the data
C. After data has been successfully committed to disk
D. After data has been received by a storage processor
