CCNA IP Routing Practice Question

This 200-301 practice question tests your understanding of ip routing. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: administrative distance determines the trustworthiness of a routing source by assigning a numeric value, where lower values indicate more preferred routes.. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Match each routing concept to its most accurate description.

Correct answer & explanation

Static routing: A network path manually configured by a network administrator.

Administrative distance is used by a router to select the best path when multiple routing protocols provide route information for the same destination; a lower AD is preferred. Metric is a value used by a specific routing protocol (e.g., OSPF cost, EIGRP composite metric) to compare routes within that protocol; a lower metric is preferred. A default route (0.0.0.0/0) is the entry used when no other more specific route matches the destination. A floating static route is a static route configured with a higher administrative distance than the primary route, so it becomes active only when the primary route fails.

Key principle: Administrative distance determines the trustworthiness of a routing source by assigning a numeric value, where lower values indicate more preferred routes.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Static routing: A network path manually configured by a network administrator.

    Why this is correct

    Health check routing uses periodic probes to verify endpoint health and only sends traffic to endpoints that respond successfully, ensuring high availability.

    Related concept

    Administrative distance determines the trustworthiness of a routing source by assigning a numeric value, where lower values indicate more preferred routes.

  • Dynamic routing: A network path automatically determined by routing protocols based on current topology.

    Why this is correct

    Geolocation routing uses the user's IP address to determine their location and route traffic accordingly, but it is not about endpoint health.

    Related concept

    Administrative distance determines the trustworthiness of a routing source by assigning a numeric value, where lower values indicate more preferred routes.

  • Default route: A catch-all route used when no specific route matches the destination.

    Why this is correct

    Latency routing measures network delay and routes to the fastest responding endpoint, but it does not involve health checks.

    Related concept

    Administrative distance determines the trustworthiness of a routing source by assigning a numeric value, where lower values indicate more preferred routes.

  • Policy-based routing: A routing method that forwards packets based on criteria other than destination IP.

    Why this is correct

    Weighted routing is used for load balancing by proportionally distributing traffic, not for checking endpoint health.

    Related concept

    Administrative distance determines the trustworthiness of a routing source by assigning a numeric value, where lower values indicate more preferred routes.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Learners often confuse administrative distance with metric: AD compares trust between protocols, while metric compares path quality within a single protocol.

Detailed technical explanation

How to think about this question

Routing decisions in Cisco networks rely on multiple concepts to determine the best path for forwarding packets. Administrative distance (AD) is a value assigned to each routing source, such as static routes, OSPF, or EIGRP, to indicate trustworthiness. Lower AD values mean higher preference. Metrics, on the other hand, are used within routing protocols to evaluate the quality of multiple paths to the same destination, considering factors like bandwidth, delay, or hop count. A default route is a special static route that matches all destinations not explicitly listed in the routing table, providing a fallback path. When a router receives multiple routes to the same destination, it first compares administrative distances to select the most trusted routing source. If multiple routes come from the same protocol, it then compares their metrics to choose the best path. Default routes are used when no specific route matches the destination IP, ensuring packets are forwarded rather than dropped. Floating static routes are configured with a higher administrative distance than the primary route, so they remain inactive until the preferred route fails, enabling seamless failover without dynamic routing protocol involvement. A common exam trap is confusing administrative distance with metric, leading to incorrect route selection understanding. Administrative distance compares route sources globally, while metrics compare paths within a single routing protocol. Another pitfall is misunderstanding floating static routes as primary routes; they only activate when the preferred route is lost. Practically, this design allows network engineers to implement backup routes that do not interfere with normal routing but provide immediate failover, enhancing network reliability and stability.

KKey Concepts to Remember

  • Administrative distance determines the trustworthiness of a routing source by assigning a numeric value, where lower values indicate more preferred routes.
  • Routing metrics quantify the cost of a path within a routing protocol, influencing route selection based on parameters like bandwidth, delay, or hop count.
  • A default route acts as a catch-all path used when no specific route matches a destination IP address in the routing table.
  • Floating static routes are manually configured backup routes with higher administrative distance values, remaining inactive until the primary route fails.
  • Routing protocols use metrics internally to compare multiple paths to the same destination and select the best one for installation in the routing table.
  • Administrative distance is used to choose between routes learned from different routing protocols or sources, not between paths within the same protocol.
  • Default routes simplify routing tables by providing a single route for unknown destinations, reducing the need for extensive route advertisements.
  • Floating static routes provide network redundancy by enabling automatic failover without dynamic routing protocol intervention.

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.

Key takeaway

Administrative distance determines the trustworthiness of a routing source by assigning a numeric value, where lower values indicate more preferred routes.

Real-world example

How this comes up in practice

A network engineer at a university connects two campus buildings via a fibre link. Both routers run OSPF, but no adjacency forms — even though both routers can ping each other. The engineer finds one router is in area 0 and the other in area 1. OSPF adjacency requires matching area numbers, hello/dead timers, and network type. IP reachability alone is not enough.
