Actual exam question for CompTIA's N10-009 exam

Question #: 3
Topic #: 5

A network administrator wants to configure a backup route in case the primary route fails. A dynamic routing protocol is not installed on the router. Which of the following routing features should the administrator choose to accomplish this task?

ANeighbor adjacency

BLink state flooding

CAdministrative distance

DHop count

Show Suggested Answer

Suggested Answer: C

Introduction to Administrative Distance

Administrative distance (AD) is a value used by routers to rank routes from different routing protocols. AD represents the trustworthiness of the source of the route. Lower AD values are more preferred. If a router has multiple routes to a destination from different sources, it will choose the route with the lowest AD.

Static Routes and Backup Routes

When a dynamic routing protocol is not used, static routes can be employed. Static routes are manually configured routes. To ensure a backup route, multiple static routes to the same destination can be configured with different AD values.

Configuring Static Routes with Administrative Distance

The primary route is configured with a lower AD value, making it the preferred route. The backup route is configured with a higher AD value. In the event of the primary route failure, the router will then use the backup route.

Example Configuration:

plaintext

Copy code

ip route 192.168.1.0 255.255.255.0 10.0.0.1 1

ip route 192.168.1.0 255.255.255.0 10.0.0.2 10

In the above example, 192.168.1.0/24 is the destination network.

10.0.0.1 is the next-hop IP address for the primary route with an AD of 1.

10.0.0.2 is the next-hop IP address for the backup route with an AD of 10.

Verification:

After configuration, use the show ip route command to verify that the primary route is in use and the backup route is listed as a candidate for use if the primary route fails.

CompTIA Network+ guide explains the concept of administrative distance and its use in static routing configuration (see page Ref 9Basic Configuration Commands).

Link state flooding sounds complicated for this situation.

Hop count won't help with redundancy, that's for sure.

Link state flooding sounds familiar, but I can't recall how it relates to backup routes. I might be mixing it up with something else.

Didn't we practice a similar question where we had to choose between routing metrics? I feel like administrative distance was the key there too.

I'm not entirely sure, but I think hop count is more about measuring the distance rather than configuring a backup route.

I'm a bit confused on this one. I was considering B - Link state flooding, since that could potentially help with backup route discovery. But I'm not sure if that's the right approach without a dynamic routing protocol. Hmm, tough call.

Okay, let me think this through. A dynamic routing protocol isn't installed, so that rules out options related to routing protocols. I'm leaning towards C - Administrative distance as the best choice here.

Hmm, I'm not sure about this one. I was thinking maybe it's D - Hop count, since that could be used to prefer a shorter backup route. But I'm not totally confident on that.

This seems like a straightforward routing question. I think the answer is C - Administrative distance. That allows you to set a backup route with a higher administrative distance than the primary route.

Hmm, I'm a bit confused on this one. I know IIS is related to web servers, but I'm not sure if it needs to be installed on the deployment computer or the client computers. I'll have to think this through carefully.

I've worked with IIS before, and I'm pretty sure the web server logs are stored in the SystemDrive%\ inetpub\LogFiles\logs\W3SVCN directory. That seems like the most logical place to look for this setup.
