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. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

A floating static route is configured with a higher administrative distance than the primary route.

Option B is correct because a floating static route is configured with a higher administrative distance to serve as a backup when the primary route fails. Option D is correct because an IPv6 default static route uses the prefix ::/0 to match all destinations. Option A is incorrect because a default static route can be used independently of whether dynamic routing protocols are configured; it is simply a route with destination 0.0.0.0/0. Option C is incorrect because a floating static route must have a higher AD, not lower, than the primary route. Option E is incorrect because an IPv6 static route cannot specify an IPv4 address as the next-hop; it must use an IPv6 address or an outgoing interface.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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

  • A default static route is used when no dynamic routing protocols are configured.

    Why it's wrong here

    A default static route is used as a gateway of last resort for any destination not in the routing table, regardless of whether dynamic protocols are configured. It is not dependent on the absence of dynamic routing.

  • A floating static route is configured with a higher administrative distance than the primary route.

    Why this is correct

    A floating static route is a backup route that is installed in the routing table only when the primary route (with a lower AD) is not available. By assigning a higher AD, the router prefers the primary route when it is reachable.

  • A floating static route must have a lower administrative distance than the primary route.

    Why it's wrong here

    A floating static route is designed to be a backup; therefore, it must have a higher AD than the primary route so that the primary route is preferred.

  • An IPv6 default static route uses the prefix ::/0.

    Why this is correct

    The IPv6 default route is represented by the prefix ::/0, which matches any IPv6 destination. It is the equivalent of 0.0.0.0/0 in IPv4.

    Related concept

    Read the scenario before looking for a memorised answer.

  • An IPv6 static route can specify an IPv4 address as the next-hop.

    Why it's wrong here

    IPv6 static routes require an IPv6 next-hop address. Using an IPv4 address would be invalid because the router would not be able to resolve it in the IPv6 routing table.

Option-by-option analysis

Why each answer is right or wrong

Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.

A floating static route is configured with a higher administrative distance than the primary route.Correct answer

Why this is correct

A floating static route is a backup route that is installed in the routing table only when the primary route (with a lower AD) is not available. By assigning a higher AD, the router prefers the primary route when it is reachable.

A default static route is used when no dynamic routing protocols are configured.Wrong answer — click to see why

Why this is wrong here

A default static route is used as a gateway of last resort for any destination not in the routing table, regardless of whether dynamic routing protocols are configured. It is not dependent on the absence of dynamic routing.

Why candidates choose this

Students may think that default routes are only needed when there is no dynamic routing, but in reality, they are often used alongside dynamic routing to provide a backup path or to reach external networks.

A floating static route must have a lower administrative distance than the primary route.Wrong answer — click to see why

Why this is wrong here

A floating static route is designed to be a backup; therefore, it must have a higher AD than the primary route so that the primary route is preferred.

Why candidates choose this

Students often confuse administrative distance with metric, thinking that a lower AD means a better route, but for floating static routes, the backup must have a higher AD to be less preferred.

An IPv6 static route can specify an IPv4 address as the next-hop.Wrong answer — click to see why

Why this is wrong here

IPv6 static routes require an IPv6 next-hop address. Using an IPv4 address would be invalid because the router would not be able to resolve it in the IPv6 routing table.

Why candidates choose this

Students may think that since routers can handle both IPv4 and IPv6, they can mix address families in static routes, but the next-hop must match the address family of the route.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the misconception that a floating static route must have a lower administrative distance than the primary route, when in fact it must be higher to serve as a backup.

Detailed technical explanation

How to think about this question

Administrative distance (AD) is a Cisco-proprietary metric used to rank the trustworthiness of routing information sources; for example, a directly connected route has an AD of 0, a static route defaults to 1, and OSPF has an AD of 110. By configuring a floating static route with an AD of, say, 200, it only becomes active in the routing table when the primary route (e.g., an OSPF-learned route with AD 110) is removed due to a link failure. In IPv6, the default static route uses the prefix ::/0, which matches any IPv6 destination, analogous to 0.0.0.0/0 in IPv4.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

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

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
