CCIE Enterprise Infrastructure Flashcards

Which Cisco technology provides a centralized controller-based approach for managing enterprise SD-WAN deployments?

Answer: Cisco vManage

Cisco vManage is the centralized NMS and controller for SD-WAN deployments, providing policy, monitoring, and orchestration.

In Cisco SD-WAN, which plane is responsible for distributing routing and policy information between WAN Edge routers?

Answer: Control plane

The control plane (vSmart) distributes routing and policy information to WAN Edge routers using OMP (Overlay Management Protocol).

What protocol does Cisco SD-WAN use to exchange routing information between vSmart controllers and WAN Edge routers?

Answer: OMP

Overlay Management Protocol (OMP) is the routing protocol used within Cisco SD-WAN between vSmart controllers and WAN Edge devices.

Which Cisco DNA Center feature automates network configuration based on business intent rather than device-level CLI?

Answer: Intent-based networking

Intent-based networking in Cisco DNA Center translates high-level business policies into device-level configurations automatically.

In EIGRP, what is the metric used as the primary path to a destination called?

Answer: Feasible distance

Feasible distance (FD) is the best metric from the local router to the destination network, used to select the successor route.

Which spanning-tree feature provides rapid convergence by pre-assigning port roles before a topology change occurs?

Answer: RSTP

Rapid Spanning Tree Protocol (RSTP) achieves fast convergence through pre-assigned port roles (alternate and backup) and rapid state transitions.
