Quiz 7C: Install and Troubleshoot Routers

Where are edge routers typically placed in a network?

• At the core of the network

• Within internal subnets

• At the network perimeter

• Within WAN interfaces

What distinguishes edge routers from internal routers?

• Edge routers have no public interfaces.

• Edge routers do not support VLANs.

• Edge routers are more expensive.

• Edge routers are positioned within internal subnets.

What is the function of an internal router in a network topology?

• To provide access to the Internet

• To control traffic between local subnets

• To perform framing for WAN access

• To link physically remote networks

How are VLANs routed in scenarios where traffic must be passed between them?

• Through physical interfaces

• Through internal routers only

• Through subinterfaces on routers

• Through layer 3 switches

What is a characteristic of layer 3 capable switches?

• They have WAN interfaces.

• They are used primarily for routing at the network edge.

• They use software-based forwarding.

• They optimize routing between VLANs.

How are router appliances typically configured?

• Locally via a console port

• Remotely via a loopback interface

• Locally via a loopback interface

• Remotely via a console port or SSH

What command is used to view and modify the routing table on Windows hosts?

• route print

• route add

• ip route show

• ip route add

Which tool is used to test the whole path between two nodes in a network?

• ping

• tracer

• traceroute

• netstat

How does traceroute typically diagnose network issues?

• By sending ICMP Echo Request probes

• By sending UDP probe messages

• By comparing per-hop latency

• By sending ICMP Time Exceeded error messages

What is the purpose of a holddown timer in routing protocols?

• To discard routing updates

• To prevent routing loops

• To reduce per-hop latency

• To identify network failures
