Juniper Juniper Certifications JN0-682 Questions & Answers

• Question 91:

  You are asked to enable visibility into your EVPN-VXLAN network traffic by monitoring traffi continuously. Which two statements are correct in this scenario? (Choose two.)

  A. You cannot enable sFlow monitoring on each interface individually.

  B. The sFlow agent is installed by default on your OFX Series switch.

  D. The sFlow agent needs to be manually installed on your QFX Series switch.

  Correct Answer: BC

• Question 92:

  You are troubleshooting a connectivity issue across a VXLAN overlay network. In the exhibit, you are using the ping overlay command from a local VTEP residing on a OFX 5120 to a remote VTEP residing on a separate QFX5120.

  

  

  What is the problem in this situation?

  A. The VXLAN controller is down.

  B. VXLAN VN1100 is not configured on the local VTEP

  C. VXLAN VN1100 is not configured on the remote VTEP.

  D. VXLAN VN1100 is not configured on both end points.

  Correct Answer: C

• Question 93:

  You are asked to deploy an Ethernet bridging design in a data center with the criteria shown below.

  -Routing must occur on the spine devices.

  -VTEPs must terminate on the leaf devices.

  -Facilitate inter-VLAN communication.

  -Layer 2 gateways must be present on spine and leaf devices.

  Which architecture should you use in this scenario?

  A. edge-routed bridging architecture

  B. centrally-routed bridging architecture

  C. bridge overlay architecture

  D. collapsed spine architecture

  Correct Answer: B

• Question 94:

  You are deploying an EBGP IP fabric. In this scenario, which statement is true?

  A. Each spine should peer with every other spine using physical addresses.

  B. Each spine should peer with each leaf using loopback addresses.

  C. Each spine should peer with every other spine using loopback addresses.

  D. Each spine should peer with each leaf using physical addresses.

  Correct Answer: A

• Question 95:

  You want to configure redundant Layer 3 gateways.

  In this scenario, which two juniper best practices would accomplish this task? (Choose two.)

  A. Allowing Junos to dynamically create the virtual MAC address of the IRB interface

  B. Configuring both IRB interfaces manually with the same IP address

  C. Configuring both IRB interfaces manually with the same address

  D. Allowing Junos to dynamically create the virtual IP address of the IRB interface

  Correct Answer: BD

• Question 96:

  You are asked to implement VXLAN in your data center network. You must choose between implementing EVPN signaling and multicast signaling. Which two statements are correct in this scenario? (Choose two.)

  A. EVPN signaling reduces ARP flooding and multicast signaling does not.

  B. EVPN signaling propagates MAC addresses across the network and multicast signaling does not.

  C. EVPN signaling uses a standards-based protocol and multicast signaling does not.

  D. EVPN signaling enables distributed Layer 3 gateways and multicast signaling does not.

  Correct Answer: BC

• Question 97:

  You are logged in to Leaf 1. When examining the routing table, you notice that you have no routes from Leaf 2.

  

  Referring to the exhibit, which two commands would you use to troubleshoot the problem? (Choose two.)

  A. From Leaf 2, issue the show route advertising-protocol bgp 172.16.1.2 command.

  B. From Spine 1, issue the show route advertising-protocol bgp 172.16.1.1 command.

  C. From Spine 1, issue the show route advertising-protocol bgp 172.16.1.2 command.

  D. From Leaf 1, issue the show route receive-protocol bgp 172.16.1.1 command.

  Correct Answer: CD

• Question 98:

  Which two statements describe MAC address learning for VPLS and EVPN? (Choose two.)

  A. VPLS learns MAC addresses in the data plane

  B. EVPN learns MAC addresses in the data plane

  C. EPLS learns MAC addresses in the control plane

  D. EVPN learns MAC addresses in the control plane

  Correct Answer: AD

• Question 99:

  In the exhibit, VM1 is part of the same VXLAN segment as VM3.

  

  Which type of message will R1 initially send to R2 so that VM1 receives BUM traffic from VM3?

  A. PIM Join

  B. PIM Register message

  C. IGMP Join (S, G)

  D. IGMP Join (*.G)

  Correct Answer: A

• Question 100:

  What is an advantage that EVPN has over VPLS when used for DCI?

  A. mass MAC withdrawal

  B. transparent BPDU transport

  C. active/standby multihoming

  D. reverse path forwarding

  Correct Answer: A
