You are attempting to merge two Brocade VDX switches running in fabric mode, but they
segment.

Referring to the exhibit, what is the reason?

You have a Brocade VCS Fabric and one Brocade VDX has the multicast root manually
assigned with the highest priority. You are going to remove that VDX from the fabric. Which
switch will become the multicast root if no other device has the priority set?

A customer would like to increase the bandwidth to servers connected to a Brocade VCS
Fabric. Two 10 Gbps NICs to the server were teamed, but now there is no IP connectivity to
the Brocade VDX 6740. Which two switch changes, depending upon the hypervisor platform,
should be used to correct the 20 Gbps connection to the server? (Choose two.)

Your customer has performance problems and suspects dropped packets between the core
router and the Brocade VCS Fabric. You determine that port Te 1/0/5 is connected to an old
database server with a high transaction rate. VDX1# show interface stats brief

Referring to the exhibit, what is the cause of the discarded packets on the port channel from
the core?

Your customer wants to establish a LAG connection on a Brocade VDX 6740T-1G
connecting to another vendor’s switch using 1 GbE interfaces. Every time they try to enable
the port channel, the interfaces shut down. In this situation, which statement is true?

You just connected a new Brocade VDX 6740T-1G switch to the top of rack. You want to
connect two 40 GbE uplinks to VDX1 and two 40 GbE uplinks to VDX2. Two of the links
come online and two of them are segmented. What is a reason for this problem?

You want to create trunks with your existing 40 GbE ISL connections between two Brocade
VDX 8770s using NOS 4.1.1. The two VDX 8770s are not forming a trunk as expected.

Referring to the exhibit, which two steps are required? (Choose two.)

You see a large number of alerts in Brocade Network Advisor on a Brocade VDX switch.
You are asked to gather information to send to technical support for analysis.
What information should you send? (Choose three.)

When connecting the Brocade VDX Fabric to an Ethernet switch with spanning tree
disabled, CPU utilization goes up indicating a loop.

What is causing the loop?
