A. OSPF

B. IBGP

C. EBGP

D. MPLS

QUESTION 3

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

A. to stop the transmission of transit multicast traffic when there are no interested receivers attached to a remote VTEP.

B. to disallow IGMP requests for the group 239.0.0.1 from hosts attached to the local VTEP.

C. to disable the multicast group 239.0.0.1 across the entire VXLAN.

D. to stop the reception of transit multicast traffic when there are no interested receivers attached to the local VTEP.

QUESTION 4

You are creating a new EVPN and are asked to selectively accept certain MAC advertisement routes from your EVPN
peers using VXLAN encapsulation.
Which statement is correct in this scenario?

A. You can use MAC filtering to filter out unwanted routes.

B. You can use VRF import policies and route distinguisher values to filter out unwanted routes.

C. You can use VRF import policies and community values to filter out unwanted routes.

D. You can use firewall filters to filter out unwanted routes.

QUESTION 5

You want to configure redundant Layer 3 gateways.
In this scenario, which two Juniper best practices would accomplish this task? (Choose two.)

A. configuring both IRB interfaces manually with the same MAC address.

B. allowing Junos to dynamically create the virtual IP address of the IRB interface.

C. configuring both IRB interfaces manually with the same IP address.

D. allowing Junos to dynamically create the virtual MAC address of the IRB interface.

QUESTION 6

Host1 and host2 are connected to an EVPN signaled VXLAN overlay, and must have Layer 3 connectivity. The VNI and
VLAN assignments are shown in the exhibit.
lead4pass jn0-681 practice test q6
In this scenario, which two statements are true? (Choose two.)

A. The ESI assigned to the host1 link will be different from the ESI assigned to the host2 link.

B. The VNI assigned to the host1 link must be the same as the VNI assigned to the host2 link.

C. A Layer 3 gateway can be configured on the spine devices.

D. A Layer 3 gateway can be configured on the leaf devices.

QUESTION 7

You host a multitenant data center that runs VMware. You must perform deep packet inspection on all inter-tenant traffic
that is flowing between the VMs within the same hypervisor. Your solution must provide security services without
needing to leave the physical device.
In this scenario, what should you do to solve this problem?

A. Use separate vSwitches to isolate each tenant\\’s networks and use IP tables to evaluate inter-tenant traffic.

B. Use VLANs to isolate each tenant\\’s networks and use an SRX Series device to evaluate inter-tenant traffic.

C. Use a vMX device to isolate each tenant\\’s networks and use with firewall filters to evaluate inter-tenant traffic.

D. Use separate vSwitches to isolate each tenant\\’s networks and use a vSRX Series device to evaluate inter-tenant traffic.

QUESTION 8

You are troubleshooting an L3VPN that is part of an EVPN/MPLS DCI. You notice that the EVPN overlay BGP session
toward 10.29.50.4 is unable to establish.
lead4pass jn0-681 practice test q8
Why is the BGP session failing to establish?

A. The vrf-table-label value is not configured in the remote PE.

B. The route-distinguisher value on the local PE is incorrect.

C. There is no route for 192.168.5.5 in inet.3.

D. There is no route for 192.168.5.5 in VPN.inet.0.

QUESTION 9

Which two statements describe an IP fabric? (Choose two.)

A. Open standards allow for vendor interoperability.

B. Each leaf should have a connection to each spine.

C. xSTP protocols should be used to prevent loops.

D. Traffic should always follow a single path.

QUESTION 10

You are deploying a VXLAN using EVPN signaling overlay network in your new data center. You are able to establish
your MP-BGP peering sessions and see your EVPN routes, but traffic will not traverse the VXLAN using EVPN
signaling overlay network.
What is the solution to this problem?

A. Increase the MTU on the logical VTEP source interface of all devices participating in VXLAN using EVPN signaling.

B. Enable the MTU-discovery feature on the MP-BGP peering sessions between all VXLANs using EVPN signaling peers.

C. Increase the protocol MTU on all devices participating in VXLAN using EVPN signaling.

D. Increase the physical MTU on all ports on all devices participating in VXLAN using EVPN signaling.

QUESTION 11

Your colleague has begun working on the base configuration for an active-active multihomed EVPN connection shown in the exhibit
lead4pass jn0-681 practice test q11
Which two actions will ensure a successful implementation? (Choose two.)
