質問 2

A customer has two identically configured Linux hosts (OS version, memory, CPU) attached to the same network. One host is NFS-attached and the other is FC-attached to an EMC VNX. Both the NFS file systems and the SAN LUNs are created from four RAID 5 (4+1) RAID groups. LUNs are not shared between file and block and each host generates the same size I/O.
The customer reports the FC-attached host is able to achieve much greater throughput than the NFS-attached host.
What is the source of the performance difference between the file and block configurations?

（A）Host Patch levels

（B）FC encapsulation overhead

（C）NFS version

（D）Ethernet Network

質問 3

Refer to the exhibit.

LUN 30 is a 50 GB LUN on a 4+1 R5 group consisting of 300 GB drives. It is the only active LUN. I/O size is 4 kB.
What can you infer about the I/O access pattern to LUN 30?

（A）Full stripe writes are occurring.

（B）Coalescing is occurring.

（C）LUN I/O is single-threaded.

（D）I/O is bursty.

質問 4

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）Restart the COFW service.

（B）Enable the SnapView license.

（C）Increase the RLP storage to 30 GB.

（D）Deactivate the ISC snapshot.

（A）iSCSI

（B）FCIP

（C）DWDM

（D）FCoE

質問 8

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）Configure target LUNs 20% larger than source LUNS

（C）Use RecoverPoint, rather than LUN migration

（D）Use SAN Copy, rather than LUN migration

質問 9

How many VNX arrays can be used to source replication volumes for a single RP/SE cluster using vRPAs?

（A）Two, as long as the amount of data replicated does not exceed the amount licensed

（B）One

（C）Unlimited, as long as a license file is installed for each VNX

（D）Two, with no constraints

質問 10

A customer has a Windows-only environment connected to a Celerra gateway utilizing Symmetrix storage at their main campus site. The customer plans to install a new EMC VNX at their remote site and implement a DR solution for their Celerra. The customer requires several thin-provisioned file systems be shared and available to clients via CIFS and wants to implement VDMs. Which solution do you recommend to the customer?

（A）Use VNX Replicator to replicate the Celerra VDMs and associated file systems from the main campus site to the VNX at the remote site to provide a synchronous DR solution.

（B）Use VNX SAN Copy to replicate the Symmetrix devices associated with the Celerra file systems from the main campus site to the VNX at the remote site to provide a synchronous DR solution.

（C）Use SRDF/A to replicate the Symmetrix devices associated with the Celerra file systems from the main campus site to the VNX at the remote site to provide an asynchronous DR solution.

（D）Use VNX Replicator to replicate the Celerra VDMs and associated file systems from the main campus site to the VNX at the remote site to provide an asynchronous DR solution.
