Options:

BFD on all routers

nonstop forwarding on R1 and R3

nonstop forwarding on R3 only

graceful restart on all routers

Discussion

Question 22

An existing network solution is using BFD in echo mode. Several of the network devices are experiencing high CPU utilization which an engineer has determined is related to the BFD feature. Which solution should the engineer leverage to reduce the CPU load?

Options:

Implement slow timers between peers with low CPU resources.

Implement BED asynchronous mode between peers with low CPU resources.

Enable BFD multi-hop on the devices with low CPU resources.

Utilize carrier delay on all routers in the network.

Question 23

Questions 23

Refer to the exhibit. An engineer Is designing a multicampus Layer 3 Infrastructure using EIGRP as the routing protocol. The design must provide quick replies to queries In the event of a downlink, prevent unnecessary queries, and ensure that traffic does not unnecessarily transit the access layer. Which two actions must the engineer take for the network design? (Choose two.)

Options:

Configure core layer switches as stub routers.

Configure distribution layer switches to summarize routes to the core layer.

Configure access layer switches as stub routers.
