Q22. Click the Exhibit button.
Refer to the exhibit. Which Layer 2 feature detects a link failure between the switch and router B that decreases OSPF reconvergence to approximately 50 milliseconds?
Q23. A network engineer is designing a network that must incorporate seamless failover when a link failure occurs between the core and distribution layer. What two technologies will allow this? (Choose two.)
Q24. A campus network utilizes EIGRP to connect to.several remote branch offices.
Which configuration should be established on all branch routers to improve routing scalability and performance?
A. Configure authentication between the campus and branch offices.
B. Enable stub routing on all branch routers.
C. Adjust EIGRP k-values to utilize delay.

Q25. Which two of these are characteristics of multicast routing? (Choose two.)
A. multicast routing uses RPF.
B. multicast routing is connectionless.
C. In multicast routing, the source of a packet is known.
D. When network topologies change, multicast distribution trees are not rebuilt, but use the original path
E. Multicast routing is much like unicast routing, with the only difference being that it has a a group of receivers rather than just one destination
