ISP-A is advertising the 200.0.3.0/24 route to R1. R1 is advertising this BGP route to R2 but the route is hidden on R2.

Referring to the exhibit, which statement is correct about the 200.0.3.0/24 route?

A. The route is unusable because the next hop is not reachable from R2.

B. The route is unusable because it has not been verified.

C. The route is hidden because R1 is changing the next hop to 192.168.16.1.

D. The route is hidden because R2 has a more preferred route.

A colleague recently implemented MSTP in your Layer 2 network and is having trouble determining why it is not working properly. You are asked to review the outputs provided in the exhibit to determine the cause.

Referring to the exhibit, what is causing the issue?

A. The region name is configured the same on both devices.

B. The VLAN mapping is configured incorrectly.

C. The MSTP revision is configured incorrectly.

D. The bridge priority has not been configured correctly.

You are asked to configure a CoS weighted tail drop profile on your EX Series switch that causes all traffic in the best effort queue to drop when the queue is 90 percent full.

Which configuration will accomplish this request?

A. [edit class-of-service] drop-profiles { be_dropp { fill-level 90; drop-probability 100; } }

B. [edit class-of-service] drop-profiles { be_dropp { interpolate { fill-level 90; drop-probability 100; } } }

C. [edit class-of-service] drop-profiles { be_dropp { fill-level 90; } }

D. [edit class-of-service] drop-profiles { be_dropp { fill-level 90; drop-probability 90; } }
