A network administrator is troubleshooting a routing loop in an OSPF network. The administrator suspects that the control plane is not converging properly. Which action should the administrator take to diagnose the issue?

Check the data plane forwarding statistics.

Check the SNMP configuration on the routers.

Check the OSPF neighbor adjacency and the routing table on all routers.

Check the CAM table on all switches.

A network administrator is concerned about a denial-of-service (DoS) attack targeting the CPU of a router. The attack floods the router with packets that need to be processed by the CPU, such as packets destined to the router's own IP address. To protect the router's ability to forward transit traffic, what should the administrator implement?

Management plane protection to restrict SSH access

Control plane policing (CoPP) to rate-limit traffic destined to the control plane

Data plane policing to rate-limit all transit traffic

Disable the control plane protocols to reduce CPU load

A network engineer is designing a new router and wants to ensure that a failure in the management plane does not affect the router's ability to forward traffic. Which design approach should the engineer use?

Implement logical separation between the management plane and the data plane.

Use only software switching for the data plane.

Run all management protocols on the same CPU as the data plane.

Disable the control plane to free resources for the data plane.

In a network device, how are the management, data, and control planes typically implemented?

As software-only components that cannot use hardware acceleration

As a single integrated function with no distinction

As logically distinct functions that may share hardware but are isolated in operation

As physically separate hardware components that cannot interact

A network architect is designing a new router and wants to ensure that a denial-of-service attack targeting the control plane does not affect the router's ability to forward traffic. Which design approach should the architect use?

Implement control plane policing to rate-limit control plane traffic.

Place the control plane on the same CPU as the data plane.

Disable the control plane to free resources for the data plane.

Use only software switching for the data plane.
