A customer configures replication between two data movers for their VDM environment. The primary data mover has one 1 Gb copper ethernet port and the destination Data Mover has one 10 Gb optical network port. The customer completes a failover test and then remote clients report they are unable to access data. The customer requests your assistance. What is the most likely cause of the issue observed during failover test?
A. The interface speeds do not match on both Data Movers
B. The interface on the Data Movers have a Duplex mismatch
C. The interface names do not match on both Data Movers
D. The interface medium do not match between Data Movers
A customer has recently installed ESXi 5.0 on a five host cluster attached to an EMC VNX using FCoE. EMC PowerPath/VE has been installed on all hosts in the cluster for load balancing. The customer wants to issue PowerPath commands to all the hosts from a Remote Management Server. Which server deployment will meet the customer's requirements?
A. A Virtual Server running RHEL5U2 64-bit
B. A Physical Host running Windows Server 2008
C. A Virtual Server running RHELU2 32-bit
D. A Virtual Appliance running RHELU2 64-bit
A storage administrator creates a new file system on their EMC VNX. They observe that the new file system does not perform as well as the first set of file systems they created. AVM was used to create all file systems using pool LUNs. All disks in the VNX are the same size and speed SAS drives.
When the storage administrator attempts to create another file system, using the same resources, the creation process fails. Why did the file system creation fail on the last attempt?
A. AVM is unable to fulfill the file system creation request due to a lack of mapped pool resources.
B. Thick and thin LUNs cannot be combined to fulfill the storage requirements.
C. AVM requires that pool LUNs stripe five dvols together. Only four dvols were available.
D. Thick and thin LUNs that were available to create the file system did not share the same service policy.
A customer creates a Remote Mirror of a 1 GB RAID 5 pool LUN. The primary LUN is presented to a Windows storage group. The customer wants to add a Secondary Image to the Remote Mirror. The only LUNs available are 5 GB RAID 1/0 LUNs presented to a Linux storage group. The customer reports they are unable to add the Secondary Image. What do you advise?
A. Secondary Image must be the same RAID type.
B. Secondary Image must be the same capacity.
C. Secondary Image must be in the same storage pool as the Primary Image.
D. Secondary Image must be presented to the same host type.
A customer creates an incremental SAN Copy (ISC) session for a 200 GB LUN on an EMC VNX. The session fails to start, and the customer notes the RLP (reserved LUN pool) contains 300 MB of storage. What action must be taken to get the session started?
A. Increase the RLP storage to 30 GB.
B. Deactivate the ISC snapshot.
C. Enable the SnapView license.
D. Restart the COFW service.
A customer has a Windows-only environment connected to an EMC VNX for File at their main campus site.
The customer plans to install a new EMC VNX at a remote branch office site. The new VNX will be used to
implement a DR solution for their main campus VNX using VDMs and several quota-enabled file systems
shared and available to clients via CIFS.
Which solution do you recommend to the customer?
A. Use VNX Replicator to replicate the VNX VDMs and associated file systems from the main campus site to the VNX system at the branch office site to provide an asynchronous DR solution.
B. Use VNX Replicator to replicate the VNX VDMs and associated file systems from the main campus site to the VNX system at the branch office site to provide a synchronous DR solution.
C. Use VNX SnapView Clones to copy the VNX block devices associated with the VNX file systems from the main campus site to the VNX system at the branch office site to provide a synchronous DR solution.
D. Use VNX MirrorView/A to copy the VNX block devices associated with the VNX file systems from the main campus site to the VNX system at the branch office site to provide an asynchronous DR solution.
An implementation engineer installs a DR solution to protect ten CIFS shares at site A. VNX Replicator will be used to replicate the shares from Site A to Site B. How many VDMs should be contained in this DR solution for maximum portability?
A. 10
B. 2
C. 5
D. 20
A vSphere ESXi 5.0 server is connected to a VNX LUN with several virtual machines on VMFS datastores. An administrator wants to take a snapshot of one of the virtual machines on the LUN. Which method can be used?
A. VM SnapShot
B. SnapView SnapShot
C. Storage vMotion
D. MirrorView session
A customer wants to reduce the performance impact incremental SAN Copy (ISC) has on their source LUN. They plan to use a clone between the current source and destination LUNs, and then use the fractured clone as the new ISC source LUN. The source LUN performs two hundred 4 KB random I/O per second, with a 1:1 read/write ratio.
The source LUN is 768 GB in size, and the clone will be fractured for five minutes. How much data will be copied to the destination LUN?
A. 11,250 MB
B. 22,500 MB
C. 1,125 MB
D. 4,800 MB
