CCNA IP Routing Practice Question

This 200-301 practice question tests your understanding of ip routing. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. A key principle to apply: iPv6 static routes manually define a fixed path to a specific destination prefix using an outgoing interface or next-hop address.. 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

It creates a specific IPv6 static route to 2001:db8:100::/64 out GigabitEthernet0/0.

This configuration creates an IPv6 static route to a specific destination prefix through the named outgoing interface. In practical terms, the router is being told exactly how to reach that remote IPv6 network. This is not a default route and not a dynamic-routing statement. It is a manually defined path to one destination prefix. The key concept is recognizing the difference between a specific static route and a default route.

Key principle: IPv6 static routes manually define a fixed path to a specific destination prefix using an outgoing interface or next-hop address.

Answer analysis

Option-by-option breakdown

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

  • It creates a specific IPv6 static route to 2001:db8:100::/64 out GigabitEthernet0/0.

    Why this is correct

    This is correct because the command defines a manual route to that destination prefix.

    Related concept

    IPv6 static routes manually define a fixed path to a specific destination prefix using an outgoing interface or next-hop address.

  • It enables OSPFv3 on GigabitEthernet0/0.

    Why it's wrong here

    This is wrong because the command is a static-route command, not a routing-protocol command.

    When this WOULD be correct

    If the question asked about the purpose of a configuration that includes commands like 'ipv6 ospf <process-id> area <area-id>' on GigabitEthernet0/0, then option B would be correct as it would indicate enabling OSPFv3 on that interface.

  • It creates an IPv6 default route.

    Why it's wrong here

    This is wrong because the prefix is specific, not ::/0.

    When this WOULD be correct

    In a different question setup where the configuration explicitly indicates that it is meant to route all IPv6 traffic to an unspecified destination, such as 'set ipv6 route ::/0', this option would correctly describe the creation of an IPv6 default route.

  • It converts the interface into a tunnel.

    Why it's wrong here

    This is wrong because a static route does not create a tunnel.

    When this WOULD be correct

    This option would be correct in a question that asks about a configuration that explicitly sets up a tunnel interface for IPv6 traffic, such as a GRE tunnel or an IPsec tunnel, where the configuration commands include 'tunnel' and specify tunnel endpoints.

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.

It creates a specific IPv6 static route to 2001:db8:100::/64 out GigabitEthernet0/0.Correct answer

Why this is correct

This is correct because the command defines a manual route to that destination prefix.

It enables OSPFv3 on GigabitEthernet0/0.Wrong answer — click to see why

Why this is wrong here

The command shown is an IPv6 static route configuration (ipv6 route), not an OSPFv3 configuration. OSPFv3 is enabled using the 'ipv6 ospf' command under interface configuration mode, not with a global static route command.

★ When this WOULD be the correct answer

If the question asked about the purpose of a configuration that includes commands like 'ipv6 ospf <process-id> area <area-id>' on GigabitEthernet0/0, then option B would be correct as it would indicate enabling OSPFv3 on that interface.

Why candidates choose this

Students may confuse IPv6 static routing with OSPFv3 because both involve IPv6 routing. Additionally, the interface GigabitEthernet0/0 appears in the command, leading some to think it is enabling a routing protocol on that interface.

It creates an IPv6 default route.Wrong answer — click to see why

Why this is wrong here

A default route in IPv6 uses the prefix ::/0, not a specific prefix like 2001:db8:100::/64. The command shown specifies a particular destination network, so it is a specific static route, not a default route.

★ When this WOULD be the correct answer

In a different question setup where the configuration explicitly indicates that it is meant to route all IPv6 traffic to an unspecified destination, such as 'set ipv6 route ::/0', this option would correctly describe the creation of an IPv6 default route.

Why candidates choose this

Students might think any static route to an IPv6 network is a default route, especially if they are not careful about the prefix length. The presence of a next-hop interface can also be associated with default routes in some contexts.

It converts the interface into a tunnel.Wrong answer — click to see why

Why this is wrong here

A static route command does not create a tunnel; it simply adds a route to the routing table. Tunnels are created using interface configuration commands like 'interface tunnel' and require additional parameters such as tunnel source and destination.

★ When this WOULD be the correct answer

This option would be correct in a question that asks about a configuration that explicitly sets up a tunnel interface for IPv6 traffic, such as a GRE tunnel or an IPsec tunnel, where the configuration commands include 'tunnel' and specify tunnel endpoints.

Why candidates choose this

The command includes an interface (GigabitEthernet0/0), and students might confuse this with tunnel interfaces that also specify an outgoing interface. However, static routes and tunnel interfaces serve entirely different purposes.

Common exam traps

Common exam trap: answer the scenario, not the keyword

A frequent exam trap is mistaking the static route command for enabling a routing protocol such as OSPFv3 or assuming it creates a default route. Candidates may also confuse static routes with tunnel interfaces. The command shown explicitly configures a static route to a specific IPv6 prefix via an interface, not a dynamic routing process or a default (::/0) route. Misreading the prefix or interface can lead to selecting incorrect answers. Recognizing that static routes are manual, precise entries that do not activate protocols or tunnels is essential to avoid this trap.

Trap categories for this question

  • Command / output trap

    This is wrong because the command is a static-route command, not a routing-protocol command.

Detailed technical explanation

How to think about this question

IPv6 static routing allows a network administrator to manually define a specific path for IPv6 traffic to reach a particular destination prefix. This is done by configuring a static route that specifies the destination IPv6 prefix and the outgoing interface or next-hop address. In Cisco IOS, the command syntax includes the destination prefix and the exit interface, which instructs the router to forward packets matching that prefix out the specified interface without relying on dynamic routing protocols. When configuring IPv6 static routes, the router uses the exact prefix match to determine the forwarding path. Unlike default routes, which match all destinations not found in the routing table (::/0), static routes target specific networks. This precision ensures traffic destined for the defined prefix is routed explicitly, which can be useful for controlling traffic flow, optimizing paths, or providing backup routes. The router installs this static route into the IPv6 routing table with an administrative distance of 1, making it a preferred route unless a better route exists. A common exam trap is confusing a specific static route with a default route or mistaking static route commands for dynamic routing protocol commands like OSPFv3. Static routes do not enable routing protocols or create tunnels; they simply define fixed paths. Practically, this means the router will forward IPv6 packets to the specified interface for the defined prefix only, and if the interface goes down, the route becomes unreachable unless alternate routes exist. Understanding this behavior is critical for troubleshooting and exam success.

KKey Concepts to Remember

  • IPv6 static routes manually define a fixed path to a specific destination prefix using an outgoing interface or next-hop address.
  • A static route to a specific IPv6 prefix is installed in the routing table with an administrative distance of 1, making it a preferred route unless overridden.
  • Static routes differ from default routes by specifying exact destination prefixes rather than the catch-all ::/0 prefix.
  • Static route commands do not enable dynamic routing protocols such as OSPFv3 or EIGRP; those require separate configuration.
  • Static routes do not create tunnels or change interface types; they only influence packet forwarding decisions.
  • Routers forward IPv6 packets matching the static route prefix out the specified interface, relying on manual configuration accuracy.
  • If the outgoing interface in a static route goes down, the route becomes unreachable unless alternate routes exist.
  • Understanding the difference between static routes, default routes, and dynamic routing commands is critical to avoid exam mistakes.

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

IPv6 static routes manually define a fixed path to a specific destination prefix using an outgoing interface or next-hop address.

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.
