10 Questions On Static Routing, Debugs, And RIP
Now With A Bonus Video Practice Exam!
By Chris Bryant, CCIE #12933
You'll certainly see questions on static routing, RIP, and various debugs on your CCNA and CCENT exams - and I can guarantee you'll use these skills in the real world!
To help you with both your exam prep and real-world network situations, here are 10 questions on these vital CCNA exam topics. Some have multiple choices and some do not!
Enjoy working with these questions - the answers are at the bottom of the page. And when you're done here, enroll in my CCNA OSPF Video Boot Camp - it's fun and 100% free!

5. Briefly describe a floating static route.
6. Identify the true statements regarding the following command output.
R3#
RIP: sending update to 224.0.0.9 via Serial0 (172.12.123.3)
172.12.123.0/24 -> 0.0.0.0, metric 1, tag 0
1.1.1.1/32 -> 172.12.123.1, metric 2, tag 0
2.2.2.2/32 -> 172.12.123.2, metric 3, tag 0
3.3.3.3/32 -> 0.0.0.0, metric 16, tag 0

C. The ping ip rip command was used.
D. Route poisoning is in effect.
E. Split horizon is in effect.
F. At least one of these routes is a floating static route.
G. This is a RIP version 1 update.
H. This is a RIP version 2 update.
7. Identify the true statements comparing RIP versions 1 and 2.
A. The destination address of the routing updates is the same.

D. DUAL
9. A default RIP configuration sends what version(s) of routing updates?
A. Version 1 only.
B. Version 2 only.
C. Both versions 1 and 2.

A. Version 1 only.
B. Version 2 only.
C. Both versions 1 and 2.
D. There is no default setting.

Here are the answers .. and be sure to take the Video Practice Exam on this topic at the bottom of this page!
1. (C, E). The debug running is debug ip packet. The ping was sent to 172.12.123.2, as shown by the first line of the debug (d=172.12.123.2).
2. (A, C). As in Question 1, this is the output of debug ip packet. However, this time there is no sending or rcvd in the debug output. That's because no packets are leaving the router, so we're sure not going to get any back!
We know the packets aren't leaving the router, since the word unroutable appears in the debug output. This indicates that no entry in the routing table exists for this particular destination, in this case 2.2.2.2.
3. The command undebug all was just run, resulting in the All possible debugging has been turned off message.
4. (A, C). A valid ip route command can be configured with the name of the local exit interface or the IP address of the next-hop router.
5. A floating static route is a static route with an administrative distance higher than that of the routing protocol in use. In this way, the floating static route will only appear in the routing table if the dynamically learned route is lost.
6. (A, D, H). This is the output of debug ip rip. Route poisoning is in effect, since one of the routes has a hop count of 16 - that's "unreachable" with RIP routes. We can tell this is a RIPv2 update since it's multicast to 224.0.0.9. RIPv1 updates are broadcast to 255.255.255.255.
7. (D). One of the few similarities between RIP v1 and v2 is that it uses the same metric for route poisoning - 16.
8. (B). RIP uses the Bellman-Ford algorithm. OSPF uses SPF (also called the Dijkstra algorithm), and EIGRP uses DUAL.
9. (A). The default for both versions of RIP is to send only V1 updates.
10. (C). The default for both version 1 and 2 of RIP is to accept both V1 and V2 updates.
Thanks for making TBA part of your CCNA success story!
