In a Cisco SD-WAN solution, which two functions are performed by OMP? (Choose two.)

1. A. advertisement of network prefixes and their attributes
2. B. configuration of control and data policies
3. C. gathering of underlay infrastructure data
4. D. delivery of crypto keys
5. E. segmentation and differentiation of traffic

Correct Answer: AB
OMP is the control protocol that is used to exchange routing, policy, and management information between Cisco vSmart Controllers and Cisco IOS XE SD-WAN devices in the overlay network. These devices automatically initiate OMP peering sessions between themselves, and the two IP end points of the OMP session are the system IP addresses of the two devices.

A network engineer is configuring OSPF on a router. The engineer wants to prevent having a route to 177.16.0.0/16 learned via OSPF. In the routing table and configures a prefix list using the command ip prefix-list OFFICE seq S deny 172.16.0.0/16. Winch two identical configuration commands must be applied to accomplish the goal? (Choose two.)

1. A. distribute-list prefix OFFICE in under the OSPF process
2. B. Ip prefix-list OFFICE seq 10 permit 0.0.0.0/0 Ie 32
3. C. ip prefix-list OFFICE seq 10 permit 0.0.0.0/0 ge 32
4. D. distribute-list OFFICE out under the OSPF process
5. E. distribute-list OFFICE in under the OSPF process

Correct Answer: AB

A)

B)

C)

D)

1. A. Option A
2. B. Option B
3. C. Option C
4. D. Option D

Correct Answer: C
CoPP protects the route processor on network devices by treating route processor
resources as a separate entity with its own ingress interface (and in some implementations, egress also). CoPP is used to police traffic that is destined to the route processor of the router such as:
+ routing protocols like OSPF, EIGRP, or BGP.
+ Gateway redundancy protocols like HSRP, VRRP, or GLBP.
+ Network management protocols like telnet, SSH, SNMP, or RADIUS.

Therefore we must apply the CoPP to deal with SSH because it is in the management plane. CoPP must be put under “control-plane” command.
