Get Certified: Proven Methods to Pass the Brocade 150-820 Exam

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.

(Truncated example of the interface stats)

Referring to the exhibit, what would be the cause of the discards?

What are three primary benefits of Access Control Lists (ACLs)? (Choose three.)

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?

Your Brocade VCS Fabric consists of two Brocade VDX 8770s and 10 Brocade VDX 6740s. The current fabric is running in VCS fabric mode. You need to add a VLAN on one switch and have it distributed to all other switches in the fabric.

Which feature is required to accomplish this task?

Exhibit:

Referring to the exhibit, which two statements are true? (Choose two.)

Which M-Series switch is supported in a Brocade VCS Fabric?

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.)

Which statement is true regarding Brocade NOS Virtual Fabrics?

You are connecting an existing Ethernet network to a Brocade VCS Fabric. You want to prevent any Layer 2 loops from forming.

Which two features would be used on the Brocade VDX to meet this requirement? (Choose two.)

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.
