Exhibit:
Referring to the exhibit, what information is determined?
You need to deploy several FCoE initiators connected through a Brocade VDX 6730. You are required to add the VDX 6730 to an existing FC SAN without increasing the number of domains.
Which action is required?
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?
You must determine where a specific virtual machine defined in a port profile is physically attached to the Brocade VCS Fabric.
Which action would you perform?
You are designing a single Brocade VCS Fabric for your data center network. Your MLX core routers are stand-alone. You want to use vLAG connectivity for devices. All link groups need to form single vLAGs.
Referring to the exhibit, which link group will accomplish this?
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?
You want to restore a configuration that was saved previously from the FTP server using this command:
copy ftp://anonymous:pass@10.255.1.89/VDX25-1-389.cfg running-config
The system responds with the error:
"Error while retrieving file over ftp. Please check the host IP address, user/password, and the permission and space left on the remote directory."
What is the problem?
You want to remove one of your Brocade VDX 6740s from your VCS fabric in Logical Chassis mode. You issue the no vcs enable command on the VDX 6740 but the switch is not removed.
What would you do to resolve the problem?
You need to provision FCoE connectivity for the servers shown in the exhibit.
Which two configuration actions must be taken? (Choose two.)
You have a Brocade VDX switch in production and you must save a backup copy of the running configuration to a remote location.
What are two ways to accomplish this task? (Choose two.)
You are building a Brocade VCS Fabric that includes one each of the Brocade VDX 8770, VDX 6740, VDX 6740T-1G, and VDX 6740T switches. All switches have base licenses. The VDX 8770 contains one 40 GbE port card.
Which two switches do you need to install the 40 GbE Port license? (Choose two.)
Your customer adds two Brocade VDX 6740s to an existing Brocade VCS Fabric in logical chassis mode with VCSID 11. After enabling logical chassis mode on both new switches, a connection is made between the two switches. A cable is then connected between one of the switches of the logical chassis. The ISL to the logical chassis is isolated with an Exchange Switch Capabilities (ESC) error, detailing a database mismatch.
What caused the problem?
Your current VCS fabric comprised of Brocade VDX 8770s is running NOS 4.0.0b in logical chassis mode. You would like to upgrade the firmware with no impact to L2 traffic.
Which two procedures would accomplish this task? (Choose two.)
Discards are incrementing on an ISL in your Brocade VCS fabric due to tail drops.
Which condition would cause this problem?
You are configuring OSPF in a Brocade VCS Fabric. The implementation will integrate with an existing OSPF network. The fabric is in logical chassis mode.
Referring to the exhibit, which three actions are correct? (Choose three.)
Which two Brocade VDX platforms allow you to deploy 40 servers with lossless iSCSI on a single switch? (Choose two.)
Your customer has connected a Linux server with a CNA to a Brocade VDX 6740 in a VCS Fabric. SAN storage is connected to Brocade VDX 6730 FC ports in the same fabric. The server cannot access the storage port. You begin troubleshooting as shown in the exhibit.

What are two causes of the problem? (Choose two.)
When congestion is experienced in a network, which type of frame is transmitted when protocol 802.3x flow control is enabled?
A Brocade VCS Fabric is running NOS 4.1.1 on two Brocade VDX 8770s and four Brocade VDX 6740s in logical chassis mode. You are required to deploy FCoE servers and Layer 3 features in the solution.
Which two licenses are required? (Choose two.)
During a network outage, several RBridges in VCS Logical Chassis mode were disconnected from the rest of the network. During this time, some configuration changes were made to those switches.
When the network connection between the separated switches is repaired, what will occur?
Which criteria determines the principal RBridge election in a Brocade VCS Fabric?
Referring to the exhibit, you connected your Brocade VDX device to an Ethernet switch running PVST+. The interfaces are up but spanning tree is not functioning for VLAN 10.
