Juniper jn0-682 practice test

Exhibit.



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.

Which event triggers the generation of a EVPN type-4 route?

• A. When unknown unicast traffic is received on an interface.
• B. When known unicast traffic is received on an interface.
• C. When a new VNI is configured.
• D. When a new ESI is configured.

Exhibit.

A VXLAN has been created between devices leaf1 and Ieaf3.
Referring to the exhibit, which statement is true?

• A. Traffic sent from host1 to host2 will be dropped on Ieaf3.
• B. Traffic sent from host1 to host2 will be tagged with VLAN ID 100 when exiting Ieaf3.
• C. Traffic sent from host1 to host2 will be tagged with VLAN ID 200 when exiting Ieaf3.
• D. Traffic sent from host1 to host2 will be dropped on leaf1.

Exhibit.

You choose the EBGP design shown in the exhibit as your IP fabric design. You must ensure that both
routes received by the spine nodes will be used for ECMP forwarding
Which BGP parameter would need to be added to the EBGP configuration of the spine nodes to
achieve this goal?

• A. multipath
• B. multihop
• C. add-path
• D. multipath multiple-as

Exhibit.

Referring to the exhibit, you must advertise the Io0.12 interface as a type-5 route.
Which configuration parameter would be used to accomplish this task?

• A. Configure auto-export under the routing instance.
• B. Configure a vrf-export policy to advertise the interface route under the routing instance.
• C. Configure an export policy to advertise the interface route under protocols evpn.
• D. Configure vrf-table-label under the routing instance.

Which two statements about the seamless EVPN-VXLAN stitching interconnect gateways are correct?
(Choose two.)

• A. IBGP is recommended for VXLAN stitching overlays.
• B. Interconnect gateways will rewrite the route target, route distinguisher. and ESI values for each stretched virtual network.
• C. All EVPN routes types are forwarded among interconnect gateways in a full-mesh manner.
• D. The interconnect gateway can reside on the super spine layer of a multi-POD data center.

Which two statements are correct about VXLANs? (Choose two.)

• A. VXLANs have smaller broadcast domains than VLANs.
• B. VXLANs have a smaller logical network identifier than VLANs.
• C. VXLANs can have a theoretical maximum of 16 million unique networks.
• D. VXLANs are an overlay technology.

You manage a data center with a 5-stage EVPN-VXLAN IP fabric. You notice that there are suboptimal
paths used between the leaf and spine as well as the spine and super spine. What is one way to solve
this issue?

• A. Configure the super spine and spine layers to all use the same ASN.
• B. Configure the spine layer for EBGP and the leaf layer for IBGP
• C. Configure the spine layer so that all spines in a POD share the same ASN.
• D. Configure the leaf layer so that all leaf devices share the same ASN.

Application developers are complaining that east-west server traffic is not being load balanced in
your new data center. What are three reasons for this behavior? (Choose three.)

• A. BGP multipath is not configured.
• B. Policies for load balancing have not been configured.
• C. MP-BGP is not exporting the correct prefix type.
• D. There is insufficient spine to leaf bandwidth.
• E. ESI active/active has not been configured.

Exhibit.

You are attempting to configure filter-based forwarding in your data center. All traffic from Host1 that
is going to Host2 should be inspected by the data center firewall. You have verified that the traffic is
being forwarded from router leaf L1's VRF-1 to its INSPECT-VRF. however, the traffic is not reaching
service L2.
Referring to the exhibit, which two steps should you take to troubleshoot the problem? (choose two.)

• A. Examine the INSPECT-VRF.evpn 0 route table on L1 for a default route that will direct the traffic to L2.
• B. Examine the INSPECT-VRF.inet. 0 route table on L1 for a default route that will direct the traffic to L2.
• C. Ensure that VRF-1 and INSPECT-VRF route targets on L1 and L2 match.
• D. Ensure that the route target in the INSPECT-VRF of L1 matches the route target of the INSPECT-VRF of L2.
