EMC VNX Solutions Expert Exam for Implementation Engineers - E20-885무료 덤프문제 풀어보기
A customer is using VNX Replicator to replicate data from a single file system to a remote
location. They are planning to replicate more file systems, but monitoring tools are showing bursts of data on the link instead of a smooth and constant flow of data. They also notice that latency on the link is higher than expected.
What would you advise them to do to make more efficient use of the link?

정답: C
A customer wants to implement file system replication between two EMC VNX. The source production file system contains data from a sequential workload that resides in a pool comprised of 2 TB NL-SAS drives. Due to cost concerns, the destination file system and SavVol volumes will also be NL-SAS and share spindles with user LUNs for another application. What should you tell the customer about this configuration?
정답: A
You are implementing a VNX into a CIFS environment.
Which server_mount command option should you use if the file system consists of database data files?
Which server_mount command option should you use if the file system consists of database data files?
정답: A
A customer has DR solution with EMC VNX configured to use a One-to-Many replication topology for its file system environment. Their environment consists of the following:
One system in the main office (Source)
One system at a local DR site
One system in the East coast office
One system in the West coast office
One system in the Canadian office
Over the weekend they experienced a failure on the source system at the main office and failed over to the local DR site. On Monday, the source system was repaired and replication was restarted and reversed from local DR site to the main office. How will replication occur to the remaining sites?

Exchange 2010 is installed on a virtual machine using VMDK files. Replication Manager is being used to take snapshots of the virtual machine files and back them up to disk. After a few weeks, the Exchange server backups stop functioning. What is the most likely reason for this failure?
정답: D
A company has two locations and wants to implement a DR solution for their Exchange databases. The following requirements factor into their SLA:
-Multi-application support.
-Continuous replication with zero data loss.
-Minimal replication load on application host.
-Support a distance of 60 km.
Which DR solution meets the SLA requirements?
-Multi-application support.
-Continuous replication with zero data loss.
-Minimal replication load on application host.
-Support a distance of 60 km.

정답: C
A customer is using MirrorView/S to replicate production data from Site A to Site C.
The production Exchange server is located at Site A and has access to LUNs 101 and 102. LUNs 101 and 102 are placed in a consistency group. Site A experiences a disaster and Site C is nowproduction. What configuration change is needed to allow the Exchange server access to Site C's LUNs 101 and 102?

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 several deduplicated file systems shared and available to clients via CIFS.

A customer asks you to design an EMC VNX for an Oracle database composed of 300 GB RAID 1 and 600 GB RAID 5 (4+1) drives. Which configuration provides maximum usable capacity balanced with reasonable performance?
정답: D
A customer's EMC VNX supports several Windows and UNIX application servers. The customer is concerned about VNX performance. By monitoring their switches, they notice there is heavy traffic between the servers and the VNX. On the VNX, the hard disks seem to be heavily accessed.
The customer wants to identify which application server workload type may be causing the observed behavior. What compound server_stats command do you suggest?
