A. R1 and R2 are configured for different metrics.

B. R1 and R2 are in different IS-IS levels.

C. R1 and R2 have different interface parameters.

D. R1 and R2 are configured for different areas.

Which two statements about Layer 2 loop prevention protocols are correct? (Choose two.)

A. With STP, a designated port can transition to the forwarding state without waiting for the protocol times to expire.

B. STP uses point-to-point and edge port designations.

C. With RSTP, a designated port can transition to the forwarding state without waiting for the protocol times to expire.

D. RSTP uses point-to-point and edge port designations.

You have an IBGP neighbor sending you routes. You need to apply a policy so it only evaluates routes being learned from this specific neighbor.

In this scenario, which statement is correct about applying the policy?

A. The policy should be applied as an export policy to the BGP group level.

B. The policy should be applied as an import policy to the BGP group level.

C. The policy should be applied as an export policy to the BGP neighbor level.

D. The policy should be applied as an import policy to the BGP neighbor level.

What are three reasons a router would send out an IS-IS link-state PDU? (Choose three.)

A. A new external route is imported from BGP.

B. The router's link to a neighbor goes down.

C. A new neighbor exists on the link.

D. The cost of a link to an existing neighbor has changed.

E. IS-IS sends link-state PDUs at random intervals.
