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 reports replication is not performing as expected and
requests your assistance. What is the most likely cause of this replication issue?

The SQL database and transaction logs have been physically isolated on separate RAID groups.
What other actions can be taken to optimize SQL performance?

A customer recently added several new applications to an EMC VNX. Some of the new
applications are experiencing very long response times. The customer suspects a high TCP
retransmission rate is causing the long response times. How could the customer determine the
TCP retransmission rate?

A customer uses MirrorView/S to replicate their production data from Site A to Site C. The
production Oracle 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 production moves
to Site C. What configuration change is needed to provide the Oracle server access to Site C’s
LUNs 101 and 102?

A customer wants to test the workload response of a newly-implemented EMC VNX for File that
will support a Windows client environment. The customer confirms the application workload will
be 80% random writes, of 8 KB or less in size, with bursty patterns of write I/O. Which tool could
be used to simulate this workload for testing purposes?

A customer plans to use SAN Copy to make consistent copies of their Windows 2003 and 2008
production environment at their remote site. Before starting the SAN Copy session, what action
should they take to ensure any pending I/O from the buffers is committed?

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 that CIFS replication does not failover to the target
site VNX. Why does CIFS replication not failover to the target VNX during the DR test?

A customer is running Exchange 2010 on an EMC VNX. The customer recovery SLA mandates
they cannot lose more than 10 MB of mail data, and the mail system cannot be down for more
than five minutes. What should you implement to meet these recovery objectives without
impacting Exchange performance or the recovery SLA?

A customer has an EMC VNX configured as an FTP server. They want to determine how many
FTP connections are currently open. What server_stat statistic type could be used to determine
this information?

There are 100 GB in updates to the transaction logs for an SQL server over an eight-hour
business day. How many I/O per second are required to support the workload?
