You are attempting to summarize routes from the 203.0.113.128/25 IP block on R8 to AS 64500. You implement the export policy shown in the exhibit and all routes from the routing table stop being advertised.

In this scenario, which two steps would you take to summarize the route in BGP? (Choose two.)

Remove the from protocol bgp command from the export policy.

Add the set protocols bgp family inet unicast add-path command to allow additional routes to the RIB tables.

Add the set routing-options static route 203.0.113.123/25 discard command.

Replace exact in the export policy with orlonger.

9. Which two statements describe PIM-SM? (Choose two)

Routers with receivers send join messages to their upstream neighbors.

10. Exhibit

user@Rl show configuration interpolated-profile { interpolate {

fill-level [ 50 75 drop―probability [ > }

class-of-service drop-profiles

];

20 60 ];

Which two statements are correct about the class-of-service configuration shown in the exhibit? (Choose two.)

The drop probability jumps immediately from 20% to 60% when the queue level reaches 75% full.

The drop probability gradually increases from 20% to 60% as the queue level increases from 50% full to 75% full

To use this drop profile, you reference it in a scheduler.

To use this drop profile, you apply it directly to an interface.
