Exhibit
Current state: O*E2 0.0.0.0/0 [110/1] via 192.0.2.2 Configured backup: ip route 0.0.0.0 0.0.0.0 198.51.100.2 250 Primary route is then removed or lost.
Based on the exhibit, which command is the best next step to verify whether the floating static route becomes active after the primary route is lost?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
show ip route
This is correct because it directly shows whether the backup default route has been installed after the primary route disappears.
B
Distractor review
show vlan brief
This is wrong because VLAN output does not verify default-route failover.
C
Distractor review
show spanning-tree
This is wrong because STP output is unrelated to route failover verification.
D
Distractor review
show power inline
This is wrong because inline power output has nothing to do with routing-table state.
Common exam trap
Common exam trap: answer the scenario, not the keyword
A common exam trap is selecting commands unrelated to routing table verification, such as "show vlan brief" or "show spanning-tree." These commands provide information about VLAN configurations or Spanning Tree Protocol status but do not show whether a floating static route has become active. Candidates may mistakenly think these outputs indicate network failover status, but only the routing table output confirms if the backup route is installed after the primary route fails. Misunderstanding the purpose of these commands leads to incorrect answers.
Technical deep dive
How to think about this question
Floating static routes are backup routes configured with a higher administrative distance than the primary route, ensuring they are only used when the primary route fails. They provide a manual failover mechanism by remaining inactive in the routing table until the preferred route disappears, at which point the floating static route becomes active and is installed in the routing table. To verify whether a floating static route has become active, the most direct method is to inspect the routing table using the "show ip route" command. This command displays all routes currently installed, including any floating static routes that have taken over due to the loss of the primary route. Other commands like "show vlan brief" or "show spanning-tree" do not provide routing table information and thus cannot confirm route failover. A common exam trap is confusing commands related to other network functions, such as VLAN or STP status, with routing verification. While these commands are important for other network tasks, they do not indicate whether a floating static route has been activated. Practically, network engineers rely on the routing table output to confirm failover behavior, making "show ip route" the definitive verification step.
KKey Concepts to Remember
- A floating static route uses a higher administrative distance to remain inactive until the primary route fails.
- The routing table only installs the floating static route when the preferred route is no longer available.
- The "show ip route" command displays all active routes, including any floating static routes currently in use.
- Commands like "show vlan brief" and "show spanning-tree" do not provide routing table or route failover information.
- Verifying route failover requires inspecting the routing table to confirm the backup route has replaced the primary route.
- Administrative distance determines route preference, with lower values preferred over higher values in the routing table.
- Floating static routes provide a simple manual failover mechanism without dynamic routing protocols.
- Exam questions may test understanding of route verification rather than route configuration.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this 200-301 question test?
A floating static route uses a higher administrative distance to remain inactive until the primary route fails.
What is the correct answer to this question?
The correct answer is: show ip route — The best next step is to examine the routing table directly after removing or losing the primary route. In practical terms, the purpose of a floating static route is to appear when the better route disappears. The clearest way to verify that behavior is to inspect the route table for the default route after the failure condition. This is a simulation-style verification question. It is not asking how to configure the route, but how to confirm failover actually happened.
