JN0-681 Online Practice Questions and Answers

Referring to the exhibit, not all routes are being exchanged by EBGP peers.

In this scenario, which BGP parameter would solve this problem?

A. multihop

B. multipath

C. multipath multiple-as

D. as-override

You need to add perimeter security to the network shown in the exhibit. All traffic must be inspected for attacks. The edge routers are using all available ports. Your solution must maintain both port and device resiliency.

In this scenario, which design would satisfy these requirements?

A. one-arm SRX Series device using LAG

B. one-arm SRX Series chassis cluster

C. inline SRX Series chassis cluster

D. inline SPX Series device using LAG

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

A. EVPN learns MAC addresses in the data plane.

B. VPLS learns MAC addresses in the control plane.

C. VPLS learns MAC addresses in the data plane.

D. EVPN learns MAC addresses in the control plane.

Referring to the exhibit, DC1 and DC2 have a DCI across a service provider WAN connection. Host1 in DC1 must have Layer 2 connectivity to host2 in DC2. A VXLAN tunnel must be created between VTEP1 and VTEP2.

In this scenario, which statement is true?

A. The service provider WAN connection cannot be an MPLS-based WAN connection.

B. VXLAN Layer 3 gateway must be provisioned at the Super Spine layer.

C. A route to the loopback address on VTEP2 must be present on VTEP1.

D. VTEP1 and VTEP2 must peer using IBGP.

You are designing an EBGP IP fabric for a multi-site data center. In this scenario, which two statements are true? (Choose two.)

A. Public AS numbers must be used.

B. Different AS numbers should be used on all devices.

C. The same AS number should be used on all devices across all data centers.

D. Private AS numbers can be used.

An EVPN-signaled VXLAN overlay has been deployed in the network shown in the exhibit. Host1 is a bare metal server, and is dual-homed to the network. The IP addresses 10.1.1.1/24 and 10.1.1.2/24 are assigned to the same physical NIC, and no virtualization is configured on the server.

In this scenario, which two statements are true? (Choose two.)

A. The MAC address associated with 10.1.1.1/24 and 10.1.1.2/24 will be the same when advertised to leaf3.

B. The connection from host1 to devices leaf1 and leaf2 must be configured as a LAG.

C. Traffic from IP address 10.1.1.1/24 must traverse the VXLAN network to reach IP address 10.1.1.2/24.

D. The ESI assigned to the leaf1-host1 link must be the same as the ESI assigned to the leaf2-hostl link.

Referring to the exhibit, each node in the IP fabric is peering to its directly attached neighbor using EBGP. Each node is peering using physical interface IP addresses. Leaf 2 and Leaf 3 are advertising the 10.1.1/24 network into EBGP. Spine 2 must be configured so that it can load-share traffic destined to the 10 1.1/24 network over both next-hop A and next-hop B.

Which two actions must be performed to accomplish this task? (Choose two.)

A. Use a load-balancing policy applied to the forwarding table.

B. Use multipath multiple-AS.

C. Use advertise-inactive.

D. Use multihop.

Which two statements describe EVPN-based VXLAN implementations? (Choose two.)

A. The movement of a virtual host requires a manual reconfiguration of the VTEP.

B. The movement of a virtual host results in the dynamic remapping of the VTEP.

C. MAC addresses are learned using multicast flooding.

D. MAC addresses are propagated using BGP updates.

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.

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.

What are two valid types of VXLAN signaling? (Choose two.)

A. EVPN

B. RSVP

C. RSTP

D. MPLS
