Your customer has a Windows system accessing his storage through iSCSI using a MDS 9509
director and the Microsoft iSCSI Driver. The Windows system has two Ethernet cards and is using
PowerPath 4.3.1 to load balance the iSCSI devices. The customer experienced a network outage
and lost one of the two iSCSI connections to the MDS. Why has the Auto-Recovery feature of
PowerPath not re-enabled the path that failed?

A customer is experience poor performance over one of the ISLs between a DS-16B2 and ED-24000. Which two commands do you run to test the bandwidth and integrity of the ISL?

A customer’s SAN consists of fabrics A and B. The customer is using PowerPath to monitor
performance on the host. The powermt display command shows that the HBA connected to fabric
B is doing 40% less I/O than the 2nd HBA connected to fabric A. What must be done to identify
the problem?

Your customer is reconfiguring the SAN. They are using an MDS switch in fabric A and a B-series
switch in fabric B. They need to share resources across the fabrics. On the weekend a merge of
the fabrics was done. Now they can not connect from fabric A to fabric B. Unique Domain IDs
exist. E_D_TOV and R_A_TOV are equal and Interop mode is set on both fabrics. What must you
do to make the two fabrics merge?

A Customer is unable to monitor a Connectrix MDS switch from ControlCenter. What must be
done for the customer to monitor the switch?

Refer to the Exhibit.

The customer has multiple MDS 9500 and MDS 9200 directors and
switches. They need to have the firmware of the MDS 9216 upgraded. The Fabric Manager’s
Software Install Wizard shown in the exhibit shows a problem that must be addressed before
continuing the upgrade. What is likely to be the problem?

Refer to the Exhibit.

Your customer connected two SANs via ISL and created one big fabric
(see diagram). This resulted in service disruptions, and the faults in one SAN are propagated to
the other SAN. What solution would you use to connect the two SANs but keep them isolated?

Using EMC’s best practices, what is the maximum number of switches for a full mesh fabric using
DS-32B2 switches?

The customer wants to consolidate their current SAN consisting of four fully populated ED-64M2s,
two DS-32M2 switches and two DS-32B2 switches. Current total throughput on the fabric is

614Gb/s. Anticipated growth is 50% increase in throughput over the next two years. The customer
wants ED-140M2. How many ED-140M2’s are required considering the future growth?
