Question 77

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 78

Which OSPF area blocks LSA Type 3, 4 and 5, but allows a default summary route?

Options:

normal

stub

NSSA

totally stubby

Question 79

Refer to the exhibit An engineer is designing an OSPF solution with these requirements:

NMS server will manage R5 and R6.

Upon failure of R1. all NMS traffic should be routed through R4.

Upon failure of the link between R5 and R6. all traffic destined for 10.6.6.6 should be routed through R4

Which solution must the engineer choose?

Options:

Advertise 172.16.1.1 into OSPF process 1 with high cost on R1.

Apply static routes on R2 and R3 with IP SLA tracking toward R5 and R6.

Enable the default-Information originate command with a higher metric on R2 to R1.

Redistribute OSPF process 1 into process 2 on R1 and R4.

Question 80

What is the purpose of a Cisco SD-Access underlay network?

Options:

to abstract IP-based connectivity from physical connectivity

to emulate LAN segments to transport Layer 2 frames over a Layer 3 network

to establish physical connectivity between switches and routers

to provide virtualization by encapsulating network traffic over IP tunnels
