What is the problem?

You are attempting to configure an ISL port to carry tagged VLANs. The ISL is currently active and you can see your neighbor switch in the show fabric isl command output. You enter the switchport command on the ISL interface but receive an error.

What is the cause of the error?

You are required to deploy servers with a single adapter that are attached to your Brocade VDX 6730 running in Access Gateway mode that will communicate with FC SAN attached storage.

Which statement is true?

You just replaced a Brocade VDX in your four-switch VCS fabric.

Which two are enabled by default on the new VDX switch? (Choose two.)

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 asked to provide time-based sampling of interface counters and statistical sampling of switched packets.

Which protocol supports these requirements?

A customer would like to manage their Brocade VDX switch but is having problems connecting from the Brocade Network Advisor server at IP address 10.10.30.15.

ip access-list standard access1

seq 5 permit host 10.10.20.0/24

seq 100 deny any log

interface Management 125/0

ip access-group access1 in

Referring to the exhibit, what are two reasons for this happening? (Choose two.)

You want to determine which link aggregation mode you should choose between a pair of Brocade VDX switches in different VCS Fabrics. You want to use frame-based distribution.

Which action should you perform?

You have implemented flow-based sFlow in your Brocade VCS Fabric by enabling sFlow globally on each Brocade VDX. You are not receiving any statistics in your sFlow collector from these devices.

What must happen to start collecting data?

Discards are incrementing on an ISL in your Brocade VCS fabric due to tail drops.

Which condition would cause this problem?

Which feature simplifies deployment of QoS for IP-based storage in a Brocade VCS Fabric?

Which two Brocade SilkWorm switches are supported in a Brocade VCS Fabric? (Choose two.)

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?

Referring to the exhibit, what information is determined?

Which two statements are true about Network OS integration with VMware vCenter? (Choose two.)

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 are deploying a new Brocade VCS Fabric. The fabric must support IP routing both within the fabric and to external routers.

Which two protocols would be used? (Choose two.)

A principal RBridge fails.

What happens to the VCS virtual IP address?

You want to implement VRRP-E between a Brocade VDX 6740, and a Brocade VDX 6730 with the protocol vrrp command.

Which two statements are true? (Choose two.)

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?

Your customer wants to take advantage of Brocade trunking to optimize the data backups over their Brocade VCS Fabric. The fabric will consist of four devices as shown in the exhibit.

The chassis are using the LC48X10G line cards.

Which two statements are correct? (Choose two.)

You are introducing a Brocade VCS Fabric to your network and want to implement a non-modular, top of rack switch with at least 40 GbE uplinks to the core.

Which switch would you use?

Your customer would like to control a Brocade VCS Fabric consisting of four Brocade VDX 6740s by using SSH to the same address on the principal switch in the fabric.

Which two attributes should be configured to accomplish this? (Choose two.)

You are asked to implement PIM in your existing Brocade VCS Fabric running NOS 4.1. The fabric consists of VDX 8770s, VDX 6740s, VDX 6730s, and VDX 6720s.

On which two Brocade VDX models would this be implemented? (Choose two.)
