JN0-663 Online Practice Questions and Answers

You manage an MX Series device which includes the configuration shown in the exhibit. Traffic marked with DSCP 000011 is entering the ge-1/0/4 interface at 102 Mbps. The traffic exits the device on the ge1/0/5 interface. No other traffic is transiting the router.

In this scenario, what happens to traffic exceeding 100 Mbps?

A. Traffic exceeding 100 Mbps is redirected to a rate limiter.

B. Traffic exceeding 100 Mbps is buffered.

C. Traffic exceeding 100 Mbps is dropped.

D. Traffic exceeding 100 Mbps is forwarded.

Referring to the ABR configuration shown in the exhibit, which three statements are correct? (Choose three.)

A. The ABR advertises a default route to the NSSA using a Type 7 LSA.

B. The ABR advertises a single Type 3 summary LSA to the backbone area for all Type 1 and Type 2 LSAs in the 192.168.16.0/20 range.

C. The ABR advertises a Type 5 external LSA to the backbone area for each Type 7 LSA in the NSSA.

D. The ABR does not summarize any routes within the 192.168.16.0/20 range.

E. The ABR advertises a single Type 5 external LSA to the backbone area for all Type 7 LSAs in the NSSA.

A customer wants to reduce LSP flooding in their IS-IS network.

Which parameter should you change to accomplish this task?

A. [edit protocols isis] user@router# set spf-options rapid-runs 5

B. [edit protocols isis interface ] user@router# set csnp-interval 65535

C. [edit protocols isis interface ] user@router# set lsp-interval 1000

D. [edit protocols isis interface ] user@router# set mesh-group

R2 has IS-IS adjacencies with R3 and R4. You want to ensure that R2 has both a level 1 and level 2 adjacency to both R3 and R4, but R2 only has one adjacency with R4.

Referring to the exhibit, which configuration change will solve this issue?

A. Change the IS-IS area on R4 to match R2.

B. Remove the level 1 disable configuration from R4.

C. Remove the level 1 disable configuration from R2.

D. Change the IS-IS area on R2 to match R4.

Which two statements about IS-IS are correct? (Choose two.)

A. Level 1 intermediate systems exchange routing information with Level 1 intermediate systems on other IS-IS areas.

B. An IS-IS router sets the attached bit in the PDUs it sends to a Level 1 area to indicate that it is a backbone router.

C. A Level 1 router can only form adjacencies with other Level 1 routers.

D. Level 2 routers can form adjacencies with either Level 1 or Level 2 routers.

What are two reasons an IBGP learned route would be hidden? (Choose two.)

A. The route is suppressed by damping.

B. The route has a next hop of the local routing device.

C. The route is rejected by an export policy.

D. The route has an empty AS path.

Referring to the exhibit, which two statements are true? (Choose two.)

A. The route-distinguisher configuration allows routes to be shared between CE-1 and CE-2.

B. The vrf-target configuration stops routes from being shared between CE-1 and CE-2.

C. The route-distinguisher configuration stops routes from being shared between CE-1 and CE-2.

D. The vrf-target configuration allows routes to be shared between CE-1 and CE-2.

A customer recently migrated to IS-IS and is concerned about resource starvation when the routing protocol daemon (RPD) starts.

To resolve this issue and protect R2 and R3, which feature should you implement?

A. Double the policy-options damping half-life timer to let the network settle.

B. Implement the overload bit and timer to signal service availability.

C. Deploy firewall filters to limit the prefix count in the route table.

D. Use the forwarding-options ip-options-protocol-queue parameter to increase resources.

Referring to the exhibit, you want to make ISP1 your preferred connection for inbound and outbound traffic.

Which two steps will accomplish this task? (Choose two.)

A. Create an export policy setting local-preference 200 and next-hop self and apply it to the IBGP peers on R2.

B. Create an export policy to prepend the ASN on advertised routes and apply it to the EBGP peer on R1.

C. Create an export policy to prepend the ASN on advertised routes and apply it to the EBGP peer on R2.

D. Create an export policy setting local-preference 200 and next-hop self and apply it to the IBGP peers on R1.

You are creating a new LDP signaled Layer 2 circuit between three customer sites.

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

A. BGP is used to exchange the virtual circuit labels with other PEs.

B. You are allowed to tunnel your LDP sessions through RSVP LSPs.

C. You are not allowed to use any RSVP-signaled LSPs in your core network.

D. LDP is used to exchange the virtual circuit labels with other PEs.
