What would you advise the customer?
A customer has a CIFS DR solution with EMC VNX using a One-to-Many replication topology. The
customer asks you to explain replication behavior under the following conditions:
Production site failover or switchover to a DR site
Replication start and reverse is performed
What would you advise the customer?
which layer describes the cabling used to create Fibre Channel SANs?
In the OSI 7-layer Network Model, which layer describes the cabling used to create Fibre Channel
SANs?
What could be the problem?
You are installing an NS702G. The install script reports there are no datamovers. You look in the
cabinet and verify the datamovers are both installed and powered on. What could be the problem?
what is the total number of spindles required to generate the required I/O per second?
Click on the calculator icon in the upper left-hand corner.
A SQL database requires 1,000 I/O per second with 85% reads and 15% writes. If RAID 1/0 is
used, what is the total number of spindles required to generate the required I/O per second?

How many bits does a WWN contain?
What would your method be for migrating the filesystem?
You have to migrate a multiprotocol filesystem from a NetApp filer to an NS702G. The customer
uses NIS for centralized user management. What would your method be for migrating the
filesystem?
Why does CIFS replication not failover to the target VNX during the DR test?
A customer has two EMC VNX configured to replicate between sites. Each VNX has dual Control
Stations. The primary Control Station at the source site fails at 6 p.m. and reboots. At 8 p.m., the
customer completes DR testing and observes CIFS replication does not failover to the target site
VNX. Why does CIFS replication not failover to the target VNX during the DR test?
Which three (3) are valid types of persistent bindings?
Which three (3) are valid types of persistent bindings?
Why is he unable to create the VDM?
The customer has just created a CIFS server, he is now trying to create a vdm on the data mover
and is unable to.
This is the command he used to create the CIFS server:
server_cifs ENG -add compname=EMC2,domain=corp.emc.com
Why is he unable to create the VDM?
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 source of the performance difference between the file and block configurations?
