What does this RPO mean in the event of a disaster?
A business has a recovery point objective (RPO) of nine hours. What does this RPO mean in the event
of a disaster?
What is the source of the performance difference between the file and block configurations?
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.
The customer reports NFS-attached host is able to achieve much greater throughput via NFSv4
versus the FC-attached host.

What is the recommended SAS LCC port configuration for optimal performance?
A client has an EMC VNX configured with four storage ports, four 15-drive DAEs (disk array
enclosures) and a total of forty drives (20 NL-SAS and 20 SAS drives). The client is using RAID 5
(4+1) RAID groups with a traditional LUN configuration.

Which software component of a backup application sends media metadata to the backup server?
Which software component of a backup application sends media metadata to the backup server?
What is causing this behavior?
A customer requests a performance review of their EMC VNX before FAST Cache is
implemented. You notice a dedicated LUN has a write size of 4 KB, and the disks are performing
writes of 8 KB. What is causing this behavior?
What is the role of the storage node in a client/server backup architecture?

What is the source of the performance difference between the file and block configurations?
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 a benefit of deploying a separate storage node in the backup environment?
What is a benefit of deploying a separate storage node in the backup environment?
What is the most likely reason for the performance issue?
A customer has two EMC VNX, one at the primary site and the other at a DR site located 100 km
away. The WAN connection between sites is a 100 Mb/s dark fiber link with 4 ms latency.
A previous storage administrator configured the pool LUNs for the file system on thin LUNs. The
file system is growing at a rate of 500 GB per week and is on a VDM. The new storage
administrator reports performance issues with the file system.
