Juniper JN0-682 JNCIP-DC Exam Practice Test Instant Access

Question 1

You are asked to increase the overall throughput of an existing IP fabric.

Which two tasks would accomplish this goal? (Choose two.)

AAdd one more leaf node to the fabric.

BAdd one uplink to all existing spine nodes from the newly added leaf node.

CAdd one more uplink from each leaf node to the newly-added spine node.

DAdd one more spine node to the fabric.

Answer : A, D

Question 2

You are implementing an EVPN overlay in your IP fabric data center. The IP fabric was stable before configuring the overlay group and EVPN-related settings. After committing the configuration shown in the exhibit on your spine device, you are no longer exchanging any routes in your underlay fabric.

In this scenario, what will solve this problem?

AYou must move the EVPN NLRI family declaration to be applied under the overlay BGP group.

BYou must remove the export policy applied to your fabric group.

CYou must remove the multipath parameter from the overlay group.

DYou must change the overlay group to establish an EBGP peering instead of IBGP.

Answer : B

Question 3

In an EVPN multicast environment, which two route types facilitate IGMP join and IGMP leave behavior for multihomed sites? (Choose two.)

Atype-7

Btype-4

Ctype-8

Dtype-3

Answer : A, C

Question 4

You are designing an IP fabric underlay network in your data center. You must ensure that your traffic can be forwarded at line rate.

In this scenario, which oversubscription model should be used?

A2:1 oversubscription

B1:2 oversubscription

C3:1 oversubscription

D1:1 oversubscription

Answer : D

Question 5

Which feature permits granular control of per-VNI type-2 and EVPN type-3 routes across an entire overlay network?

Aroute target

Bremote VTEP

CEthernet segment

Droute distinguisher

Answer : A

Question 6

You are designing a Layer 3 fabric underlay using EBGP. You will implement an E VPN-signaled

VXLAN overlay on the Layer 3 fabric.

In this scenario, what must you do in the underlay to ensure that the VXLAN overlay will be able to function properly?

AThe underlay should support the PIM protocol

BEach device in the underlay should advertise its loopback address

CThe underlay should be configured with a separate VRF tor each potential tenant

DThe underlay should advertise the host connected interlaces on all leaf device

Answer : B

For a VXLAN overlay to function properly over a Layer 3 EBGP fabric underlay, it's essential that each device in the underlay advertises its loopback address. This ensures reachability between the devices, facilitating proper tunnel establishment for the VXLAN overlay.

Question 7

What is the purpose of the command shown in the exhibit?

ATo stop the reception of transit multicast traffic when there are no interested receives attached to the local VTEP

BTo disable the group2390.0.1 across the entire VXLAN.

CTo stop the transmission of transit multicast traffic when there are no interested receives attached to a remote VTEP

DTo disallow IGMP request for the group 239.0.01 from host attached to the local VTEP
