問題1

You want to converse IP address space and reduce your fabric management overhead.
For these reasons, you decided to use unnumbered Ethernet interfaces for your IP Fabric.
Which statement is correct in this scenario?

A. The donor interface for an unnumbered interface must have only one configured IP address.

B. Only the IPv4 address family is supported on the interfaces.

C. OSPF is supported on unnumbered interfaces configured as a point-to-point connection.

D. PIM is not supported on upstream unnumbered interfaces in the PIM topology.

正確答案: C

問題2

Referring to the exhibit, R1 and R2 are QFX5100s and are acting as VXLAN Layer 2
Gateways for VLAN 100 using PIM-SIM signaling. R1 currently has an entry for Host B in its MAC table.
What will R1 do in response to receiving the ARP packet from Host A?

A. R1 will send a VXLAN packet over the RP-based multicast tree.

B. R1 will send a VXLAN packet over the (S,G) tree built to R2.

C. R1 will send a (*.G) PIM Join message to the RP.

D. R1 will send an (S,G) PIM Join message to R2.

正確答案: A

問題3

Which two statements are correct when performing a unified ISSU? (Choose two.)

A. Unicast RPF-related statistics are not saved across a unified ISSU, and the unicast RPF counters are reset to zero during a unified ISSU.

B. Unicast RPF-related statistics are saved across a unified ISSU, and the unicast RPF counters are not reset to zero during a unified ISSU.

C. The backup Routing Engine must be running the most recent software version before you can perform a unified ISSU.

D. The master Routing Engine and backup Routing Engine must be running the same software version before you can perform a unified ISSU.

正確答案: C,D

問題4

Referring to the exhibit, each leaf node is a QFX5100 acting as a VXLAN Layer 2 Gateway using EVPN signaling. Leaf 2 and Leaf 3 are both attached to the same EVPN Ethernet segment. Leaf 2 has been elected the designated forwarder for VLAN 200 on that Ethernet segment.
In this scenario, which two actions will Leaf 1 perform with the broadcast Ethernet frame received from Host A? (Choose two.)

A. Leaf 1 will send a VXLAN encapsulated copy of the Ethernet frame to Leaf 2 only.

B. Leaf 1 will send a VXLAN encapsulated copy of the Ethernet frame to both Leaf 2 and Leaf 3.

C. Leaf 1 will strip the VLAN tag from the Ethernet frame before encapsulating it in VXLAN.

D. Leaf 1 will change the VLAN tag of the Ethernet frame to 200 before encapsulating it in VXLAN.

正確答案: B,C

問題5

Referring to the exhibit, which hardware change would be made to the IP Fabric to ensure an exact 4:1 oversubscription ratio?

A. Add two leaf nodes to the IP Fabric.

B. Add three leaf nodes to the IP Fabric.

C. Add a spine node to the IP Fabric.

D. Upgrade the fabric links to 100GbE.

正確答案: C

問題6

What are three benefits of EVPN that would improve the current E-line, E-LAN, and E-Tree delivery? (Choose three.)

A. greater Multiprotocol Label Switching scale

B. native support for multihoming

C. efficient security provisioning

D. network resiliency between edge nodes

E. integrated L2/L3 connectivity

正確答案: B,D,E

問題7

You are using IBGP to deploy an IP fabric. There are four spine devices, two of which are configured as route reflectors. You notice that the other two spines are not receiving all the possible paths to each leaf, and traffic cannot be load-balanced to the leaf devices.
Which two actions will resolve this problem? (Choose two.)

A. Configure the add-path parameter on the leaf devices.

B. Configure the add-path parameter on the route reflectors.

C. Configure the multihop parameter on the route reflectors.

D. Configure the multipath parameter on the route reflectors.

正確答案: A,B
