Answer: C

Question No: 52

What is the function of a Node device in a QFabric system?

  1. It connects endpoints such as servers or storage devices to the QFabric system.

  2. It connects all edge devices in the QFabric system and directs traffic between them.

  3. It manages, monitors, and maintains all components in the QFabric system.

  4. It supports the control plane network and facilitates communications between QFabric system devices.

Answer: C

Question No: 53

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

  1. Each Node device resides in a separate server Node group.

  2. All Node devices reside in the network Node group.

  3. All Node devices reside in a single default Node group.

  4. Each Node device resides in a separate null Node group.

Answer: A

Question No: 54

You want to change the device mode of a QFX3500 to connect to a QFabric system. Which command would you use?

  1. [edit]

    user@qfabric# request chassis device-mode node-device

  2. user@qfabricgt; request chassis device-mode node-device

  3. [edit]

    user@qfabric# request system device-mode node-device

  4. user@qfabricgt; request system device-mode node-device

Answer: B

Question No: 55

Whenever you connect a Layer 2 switch to the xe-0/0/0 interface of the LC2 Node device in the server Node group of a QFabric system, the interface xe-0/0/0 on LC2 is disabled.

What is causing this problem?

  1. The xe-0/0/0 interface on the LC2 Node device is not configured for family Ethernet

    switching.

  2. The LC2 Node device is not connected to the QFabric system.

  3. Interfaces on the server Node group can connect only to servers.

  4. The interface xe-0/0/0 of the LC2 Node device detects incoming BPDUs from a Layer 2 switch.

Answer: D

Question No: 56

After initial setup on a QFabric system, you investigate a Node device interface that is operationally down.

What are two reasons for this happening? (Choose two.)

  1. improper installation of the optical transceiver on the Node device

  2. improper configuration of the protocol family on the interface

  3. improper installation of the fabric Interconnect card

  4. improper configuration of the network Node group

Answer: A,C

Question No: 57

– Exhibit –

Click the Exhibit button.

Referring to the exhibit, you want to ensure that the QFabric system will not become the root bridge and that the connection from the QFabric system to S-2 will be selected as the root port.

Which configuration will satisfy the requirements?

  1. [edit protocols rstp] user@qfabric# show bridge-priority 4k;

    interface Node-0:xe-0/0/24.0 { priority 128;

    cost 1;

    }

    interface Node-1:xe-0/0/24.0 { priority 16;

    cost 5000;

    }

    [edit protocols rstp]

  2. user@qfabric# show

    bridge-priority 32k;

    interface Node-0:xe-0/0/24.0 { priority 16;

    cost 5000;

    }

    interface Node-1:xe-0/0/24.0 { priority 128;

    cost 1;

    }

    [edit protocols rstp]

  3. user@qfabric# show bridge-priority 4k;

    interface Node-0:xe-0/0/24.0 { priority 16;

    cost 5000;

    }

    interface Node-1:xe-0/0/24.0 { priority 128;

    cost 1;

    }

    [edit protocols rstp]

  4. user@qfabric# show bridge-priority 32k;

interface Node-0:xe-0/0/24.0 { priority 128;

cost 1;

}

interface Node-1:xe-0/0/24.0 { priority 16;

cost 5000;

}

Answer: D
