Online Access Free JN0-680 Practice Test

You are deploying a VXLAN using EVPN signaling overlay network.
PE1 and PE2 are multihomed to the connected CE device.
You notice that the traffic is not load-balancing as expected.
Referring to the exhibit, which two actions will solve this problem? (Choose two.)

• A.Set the LACP system ID on PE2 to 00:00:00:00:00:01.
• B.Set the ESI on PE2 to 00:11:11:11:11:11:11:11:11:11.
• C.Set the ESI on both devices to 00:00:00:00:00:00:00:00:00:00.
• D.Set the route distinguisher on PE2 to 11.11.11.11:100.

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 strip the VLAN tag from the Ethernet frame before encapsulating it in VXLAN.
• C.Leaf 1 will change the VLAN tag of the Ethernet frame to 200 before encapsulating it in VXLAN.
• D.Leaf 1 will send a VXLAN encapsulated copy of the Ethernet frame to both Leaf 2 and Leaf 3.

You are deploying MC-LAG as shown in the exhibit.
Which statement is correct when using active/standby mode?

• A.All traffic from Server A to Host 1 will traverse the link between Server A and ex2.
• B.VCCP is used to exchange MAC addresses between MC-LAG peers.
• C.A spanning tree protocol should be used to avoid Layer 2 loops between Server A and both switches.
• D.Only ICCP control traffic is allowed through the ICL-PL connection.

Which protocol is used between VCF member devices to create a loop-free topology?

• A.RSTP
• B.MSTP
• C.LLDP
• D.VCCP

Which statement is valid for EVPN multihoming CE1 to PE1 and PE2 as shown in the exhibit?

• A.CE1 must have LACP enabled on the interfaces attached to the PEs.
• B.CE1 must have the MAC mobility extended community enabled in BGP on both the CE and PEs.
• C.The PEs must be manually configured for the ESI value on the interfaces attached to the CEs.
• D.The PEs use BPDU autodiscovery by enabling STP on the interfaces attached to CE1.
