150-820 Brocade Certified Ethernet Fabric Professional 2015 Questions and Answers

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 planning the integration of a new Brocade VCS Fabric into your legacy spanning tree environment.

In which two scenarios would configuring STP be appropriate? (Choose two.)

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

You are extending your Brocade VCS Fabric over 30 km long-distance ISLs.

Which two services are supported over these ISLs? (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?

Your customer wants their Brocade VCS Fabric to participate in a loop-free network when connecting to other switches.

Which three protocols are supported? (Choose three.)

Your customer is using Brocade Network Advisor as a trap recipient for a Brocade VCS Fabric. A Brocade VDX is discovered and the customer is testing SNMP traps by removing the power supply. You are not receiving traps.

Which three actions will determine the problem? (Choose three.)

You have three new Brocade VDX switches that are properly configured to join into a single Brocade VCS Fabric. You add two links in the same port group between each of the three switches.

Which two statements are true? (Choose two.)

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

Referring to the exhibit, what is the reason?

A customer would like to use Brocade VDX switches for connectivity to servers running at 100 Mbps and 1000 Mbps. The customer would also like the option to upgrade the switch ports to 10 Gbps for additional bandwidth in the near future.

Which Brocade VDX switch should you use?

Which switch is capable of running in stand-alone mode?

After adding a large number of servers to your Brocade VCS Fabric, you notice a severe performance impact to your FCoE traffic. You want to ensure that FCoE traffic is not impacted.

What would you do to resolve this problem?

You are connecting your Brocade VCS Fabric to a native Brocade Fibre Channel Router (FCR) using FC ports on one of your Brocade VDX switches.

Which two port types are supported? (Choose two.)

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.)

What are three Brocade VCS Fabric core technology principles? (Choose three.)

You have two Brocade VDX 6740 switches with cables connected in ports 15-18 and ports 31-34 in each switch to form ISLs between them.

How many trunks will form?

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?

Brocade Network Advisor has notified you that one of your ISLs between two Brocade VDXs is reporting a high number of errors. You log into the switch and clear the counters. You notice that the CRC and error counters are incrementing at a high rate.

What do these two errors indicate? (Choose two.)

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

Which statement is true regarding Brocade NOS Virtual Fabrics?

You want to allow help desk personnel to enable or disable only the 10 Gbps interfaces using CLI.

Which feature in Brocade NOS would you configure?

You just connected multiple Brocade VCS Fabric mode-enabled switches and you want them to form an Ethernet fabric.

Which two configurations must be applied? (Choose two.)

Which three statements are correct regarding a vLAG? (Choose three.)

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.)
