1.

Host A is connected to two Node devices in a redundant server Node group over a LAG link. Host B is connected to a Node device on a server Node group. Traffic is running between Host A and Host B. Which statement is true?

The server Node group will calculate the hash for Host A's MAC address and forward traffic to one of the Node devices participating in the redundant server Node group. The server Node group will send traffic to Host A's MAC address on both member links of the LAG. The network Node group will send traffic to Host A's MAC address on both links of LAG. The redundant server Node group will calculate the hash for Host A's MAC address and forward trafficon one of the member links of the LAG.

2.

What is a Fibre Channel N_Port?

a port that resides on an Fibre Channel switch used to connect to a host a port that resides on a Fibre Channel switch used to connect to another Fibre Channel switch a port that resides on a host or a storage device used to connect to a Fibre Channel switch a port that resides on a Fibre Channel switch used for diagnostics

3.

You must determine which FTE interfaces of a Node device named Node-1 are connected to which Interconnect device. Which operational mode command provides the desired information?

show interfaces fabric Node-1:fte* extensive show fabric administration inventory node-devices Node-1 show chassis fabric connectivity device Node-1 show fabric administration inventory interconnect-devices

4.

A new Node device joins a QFabric system. Which statement is correct?

The Node device will be placed into a server Node group named SNG-1. The Node device will be placed into a network Node group named NW-NG-1. The Node device will be placed into an automatically generated network Node group. The Node device will be placed into an automatically generated server Node group.

5.

How many traffic priorities are available in a QFabric system using enhanced transmission selection (ETS)?

2 4 8 15

6.

Which routing table is used to exchange Layer 3 routes between components in a QFabric system?

bgp.inet.0 default.inet.0 inet.0 bgp.vpn-inet.0

7.

You are troubleshooting latency on a Node device on your QFabric system and discover a Layer 2 loop. What would cause this behavior?

STP was disabled on the Interconnect devices. A switch was attached to both nodes in a redundant server Node group. Data center bridging was disabled on the affected Node device. The fabric administrator is unresponsive.

8.

Which command executed from NW-NG-0 displays the PFE ID for all nodes in the fabric?

show fabric administration inventory show virtual-chassis protocol adjacency fabric show oam fabric internal-database device show virtual-chassis status fabric

9.

A user account has the remote-debug-permission parameter set but the user is unable to log in to any devices. What is causing this problem?

The user is only configured with the qfabric-user class. The user is not a root user in the QFabric system. The user is not a superuser in the QFabric system. The Node devices have not been configured with the correct users.

10.

What is the default behavior for Node groups on a QFabric system?

Each Node device resides in a separate server Node group. All Node devices reside in the network Node group. All Node devices reside in a single default Node group. Each Node device resides in a separate null Node group.
