CCIE CCIE Enterprise Infrastructure 1 — Questions and Answers
Question 1: Which Cisco technology provides a centralized controller-based approach for managing enterprise SD-WAN deployments?
- Cisco DNA Center
- Cisco vManage (Correct answer)
- Cisco Prime Infrastructure
- Cisco ISE
Correct answer: Cisco vManage
Cisco vManage is the centralized NMS and controller for SD-WAN deployments, providing policy, monitoring, and orchestration.
Question 2: In Cisco SD-WAN, which plane is responsible for distributing routing and policy information between WAN Edge routers?
- Data plane
- Management plane
- Control plane (Correct answer)
- Orchestration plane
Correct answer: Control plane
The control plane (vSmart) distributes routing and policy information to WAN Edge routers using OMP (Overlay Management Protocol).
Question 3: What protocol does Cisco SD-WAN use to exchange routing information between vSmart controllers and WAN Edge routers?
- BGP
- OSPF
- OMP (Correct answer)
- EIGRP
Correct answer: OMP
Overlay Management Protocol (OMP) is the routing protocol used within Cisco SD-WAN between vSmart controllers and WAN Edge devices.
Question 4: Which Cisco DNA Center feature automates network configuration based on business intent rather than device-level CLI?
- Network assurance
- Intent-based networking (Correct answer)
- APIC-EM migration
- NetFlow analysis
Correct answer: Intent-based networking
Intent-based networking in Cisco DNA Center translates high-level business policies into device-level configurations automatically.
Question 5: In EIGRP, what is the metric used as the primary path to a destination called?
- Advertised distance
- Reported distance
- Feasible distance (Correct answer)
- Administrative distance
Correct answer: Feasible distance
Feasible distance (FD) is the best metric from the local router to the destination network, used to select the successor route.
Question 6: Which spanning-tree feature provides rapid convergence by pre-assigning port roles before a topology change occurs?
- PVST+
- RSTP (Correct answer)
- MST
- STP Loop Guard
Correct answer: RSTP
Rapid Spanning Tree Protocol (RSTP) achieves fast convergence through pre-assigned port roles (alternate and backup) and rapid state transitions.
