D. set policy-options as-path LOCAL-ROUTES "(65310|65441)+"

You are asked to configure a series of interface policers and firewall filters, which include policers, on the same device. You must ensure that the two configuration methods do not conflict.

What are two considerations when performing this task? (Choose two.)

A. On inbound traffic, firewall filters are applied before interface policers.

B. On outbound traffic, interface policers are applied before firewall filters.

C. On outbound traffic, firewall filters are applied before interface policers.

D. On inbound traffic, interface policers are applied before firewall filters.

Your network connects two segments of your customer's network as shown in the exhibit. They need to exchange routes between Segment 1 and Segment 2 but both segments use the same AS number.

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

A. Configure the routing-options autonomous-system loops 1 parameter on routers R1 and R4.

B. Configure the BGP group with the advertise-peer-as parameter on routers R2 and R3.

C. Configure the routing-options autonomous-system loops 1 parameter on routers R2 and R3.

D. Configure the BGP group with the as-override parameter on routers R1 and R4.

All adjacencies have been formed, no extra options have been configured, and no policies have been written.

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

A. R2 will create a default route and send it as a TLV to R1

B. R1 cannot reach R5

C. R1 can reach R5

D. R1 will create its own default route that points to R2

Which three statements are true about the show pim join output shown in the exhibit? (Choose three.)

A. This is a source-specific multicast stream.

B. The multicast receiver is still using the RP to receive the stream.

C. The multicast stream has been configured with a backup path to allow for fast reroute.

D. The multicast stream does not have an RP.

E. The shortest path to the source is through the RP.

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.

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.

Which statement is correct about BGP FlowSpec between a service provider's PE router and a customer?

A. The flow routes received from a customer are limited to /32 masks for IPv4.

B. The NLRI received from a customer is stored in the flowspec.inet.0 table.

C. The RFC deterministic traffic filtering algorithm is used by default in Junos.

D. The NLRI received from a customer is stored in the inetflow.0 table.
