Referring to the exhibit,
to minimize downtime, what is the Brocade recommended approach to fabric node upgrades?
You are designing a network with Brocade VCS Fabrics. You must support four 10 Gbps Brocade trunking ports in between the VDX switches. You need to determine which interfaces to connect.

What are two reasons for the problem? (Choose two.)
You want to capture sFlow statistics from a group of interfaces on a Brocade VDX and forward the data to your Brocade Network Advisor server.
Which three steps are required for a working configuration? (Choose three.)
In the exhibit, both MAC addresses are assigned to interface 2/0/4.
What does the (UC) indicate?
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 has configured sFlow on a four node VCS cluster which includes one Brocade VDX 8770 and three VDX 6740T-1G switches. The customer sees sFlow samples from all the interfaces on the VDX 8770 but is not seeing sFlow samples from the 1 GbE interfaces on the VDX 6740T-1G switches.
Which statement is correct?
As a network administrator, you see a very high number of receive discards in the interface statistics of an ISL within your VCS fabric. After further investigation, the discards are found to be incrementing due to tail drops.

Referring to the exhibit, what would be the cause of the discards?
You are asked to provide time-based sampling of interface counters and statistical sampling of switched packets.
Which protocol supports these requirements?
You have a VMware environment and configure AMPP with vCenter integration on your Brocade VCS Fabric.
After a successful discovery of virtual infrastructure assets, which two changes would you expect to find in the Brocade VDX configuration? (Choose two.)
You are extending your Brocade VCS Fabric over 30 km long-distance ISLs.
Which two services are supported over these ISLs? (Choose two.)
Which feature simplifies deployment of QoS for IP-based storage in a Brocade VCS Fabric?
You are using PBR in your Brocade VCS Fabric and you would like to selectively modify and route the IP packets in the hardware.
Which two would you configure? (Choose two.)
Your Ethernet fabric is running NOS 4.1.1 on two Brocade VDX 8770s and four Brocade VDX 6730s in fabric cluster mode. You are required to deploy servers connected to the VDX switches that will communicate with FC targets. Layer 3 features must be deployed in the design.
Which two licenses are required? (Choose two.)
You are providing cloud-based virtual desktops to businesses from your data center. Each business needs to be completely segmented from each other; however, to keep costs down, you decide to use a single DHCP and DNS server with the least amount of configuration.
Which three features must be configured in the Brocade VCS Fabric? (Choose three.)
Which criteria determines the principal RBridge election in a Brocade VCS Fabric?
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.)
You want to enable a Service Virtual Fabric to provide 802.1Q VLAN virtualization.
Which two statements are correct? (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?
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?
A Brocade VDX 6730 is added to an existing three node Brocade VCS Fabric running NOS 4.1. You want to manage all switches in the fabric from the principal switch.
What should you do to accomplish this task?
