質問 5

A QFabric system continuously drops Layer 3 inter-VLAN routed traffic. Host 1 is connected to SNG-1 on VLAN 10 and Host 2 is connected to SNG-2 on VLAN 20. You determine that SNG-1 does not have the ARP entry for Host 2, but the ARP entry is present on the network Node group.
Which two statements are correct? (Choose two.)

A. SNG-1 is not receiving the host route from the fabric control Routing Engines.

B. The Node devices connecting to Host 2 and Host 1 are not part of the same redundant server Node group.

C. BGP peering between SNG-1 and the fabric control Routing Engines is down.

D. SNG-2 is not advertising the host route to the fabric control Routing Engines.

正解: A,C

質問 6

You configured a BGP peering session between your QFabric system and an attached device, but the session is not coming up.
What are two reasons for this happening? (Choose two.)

A. There are no RVIs configured on the QFabric system.

B. The inet protocol family is not configured on the QFabric system.

C. There is a mismatching MED attribute configured.

D. The QFabric system is configured with two network Node groups.

正解: A,B

質問 7

You have just deployed a QFabric system and noticed that some of the attached Node and Interconnect devices are not registered in the system's inventory.
What are two reasons for the undesired inventory status? (Choose two.)

A. malfunctioning fabric control Routing Engine

B. faulty control plane connections

C. faulty data plane connections

D. malfunctioning fabric manager Routing Engine

正解: B,D

質問 8

You are cabling the data plane of a QFabric system using QFX3008-I Interconnect devices. You require an uplink capacity of 320 Gbps from each Node device.
Which two statements are true? (Choose two.)

A. You must use QFX3600 Node devices.

B. You must explicitly enable ports 13-16 as uplink ports on the Node devices.

C. You must use QFX3500 Node devices.

D. You must explicitly enable ports 4-7 as uplink ports on the Node devices.

正解: A,D

質問 9

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

A. STP was disabled on the Interconnect devices.

B. A switch was attached to both nodes in a redundant server Node group.

C. Data center bridging was disabled on the affected Node device.

D. The fabric administrator is unresponsive.

正解: B

質問 10

A customer needs to plan a QFabric system to support one hundred 10 GbE ports and twenty-eight 8 Gb Fibre Channel ports for a data center consolidation project. The infrastructure should support up to twelve 40 GbE ports in the future.
Which QFabric system configuration of Node devices will support the customer's requirements?

A. 2 QFX3500 devices and 2 QFX3600 devices

B. 3 QFX3500 devices and 1 QFX3600 device

C. 4 QFX3600 devices

D. 4 QFX3500 devices
