20+ practice questions focused on IP Routing — one of the most tested topics on the CCNA 200-301 v2 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start IP Routing PracticeWhat is the OSPF metric called?
Explanation: OSPF uses cost as its internal metric. By default, cost is derived primarily from bandwidth.
What is the effect of route summarization at an area boundary or redistribution point?
Explanation: Summarization reduces the number of routes advertised by combining contiguous networks into a shorter prefix.
What is the purpose of a default route on a router?
Explanation: A default route is used when no more specific route exists in the routing table.
What is the main reason a default route is sometimes called a route of last resort?
Explanation: A default route is called the route of last resort because the router uses it only when no more specific route matches the destination. In plain language, it is the fallback instruction the router follows when it does not have a better answer in the routing table. That makes it extremely useful for branch routers, Internet edge devices, and other places where unknown destinations should simply be sent to an upstream path. The default route is not “last” because it is slow or because it is dangerous. It is last because it is the least specific match. As soon as the router finds a more specific prefix, that route takes precedence. This is a core route-selection concept and helps explain why default routes work so well alongside more detailed routing information.
What is the main purpose of route summarization in a routed network?
Explanation: Route summarization combines multiple more-specific routes into a smaller set of broader advertisements. In plain language, it helps reduce routing-table size and can simplify the information routers exchange with each other. This can improve scalability and reduce churn because the network does not need to advertise every small route individually when a broader summary is appropriate. Summarization is not about creating VLAN tags or assigning DHCP leases. It is a routing design technique used to make route information more compact and manageable.

Practice all IP Routing questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of IP Routing. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
IP Routing questions on the 200-301 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. IP Routing is tested as part of the CCNA 200-301 v2 blueprint. Practicing with targeted IP Routing questions ensures you can handle any format or difficulty that appears.
