20+ practice questions focused on IPV6 — 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 IPV6 PracticeWhich TWO statements about IPv4 and IPv6 ACLs are true?
Explanation: Extended IPv4 ACLs filter on source and destination IP addresses, ports, and protocols, so placing them as close to the source as possible prevents unwanted traffic from traversing the network, reducing bandwidth waste and security risks. This is a best practice for extended ACLs, unlike standard ACLs which should be placed close to the destination.
A network administrator is troubleshooting an IPv6 connectivity issue on a newly deployed router. The router's G0/0/0 interface is configured with an IPv6 address using EUI-64, but hosts on that subnet cannot reach the router's link-local address. The administrator runs 'show ipv6 interface g0/0/0' and sees that the interface is up/up but the IPv6 address is not in the expected format. What is the most likely cause of the problem?
Explanation: The router's G0/0/0 interface is up/up, but the IPv6 address is not in the expected EUI-64 format. This indicates that the 'ipv6 address' command was likely omitted entirely, because if it were simply misconfigured (e.g., without the `eui-64` keyword), the router would still automatically generate a link-local address, and hosts would be able to reach it. Since hosts cannot reach the link-local address, IPv6 is not enabled on the interface at all. The correct configuration requires the `ipv6 address` command with the appropriate prefix and the `eui-64` keyword.
An IPv6 host successfully reaches neighbors on its local segment, but it cannot reach remote IPv6 destinations. The host has a global unicast address and a correct prefix length. Which missing item is the strongest suspect?
Explanation: The strongest suspect is the absence of a usable default router learned through IPv6 router advertisements or equivalent configuration. While local connectivity works because the host can communicate on its own link, remote IPv6 destinations require a next hop off the local segment. Option B is wrong because IPv6-to-IPv4 NAT is unnecessary for native IPv6 communication and would not be the primary cause of off-link failure. Option C is wrong because a VLAN trunk on the host NIC is for carrying multiple VLANs, not for enabling off-link routing. Option D is wrong because a second global unicast address does not provide a default route; it only adds another local address.
Which IPv6 address type is automatically created on an interface and used for communication on the local link only?
Explanation: Every IPv6-enabled interface generates a link-local address, typically in the FE80::/10 range. It is used for neighbor discovery, local communication, and next-hop resolution on the same link.
A standard ACL and an extended ACL are both available for a design. Which requirement most strongly indicates that an extended ACL is needed?
Explanation: An extended ACL is most strongly indicated when the policy must match not just on source address, but also on destination, protocol, or port information. In practical terms, if the requirement is something like “block HTTP but allow SSH” or “deny traffic to one server but not another,” a standard ACL is too limited because it mainly matches only the source. Option B (matching only one source subnet) can be done with a standard ACL, so it does not demand an extended ACL. Option C (placement near destination) is a guideline for standard ACLs, not a reason to choose an extended ACL. Option D (IPv6) is irrelevant because the scenario explicitly states both ACL types are available and standard ACLs do not exist for IPv6—this question is about IPv4 ACLs.

Practice all IPV6 questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of IPV6. 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
IPV6 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. IPV6 is tested as part of the CCNA 200-301 v2 blueprint. Practicing with targeted IPV6 questions ensures you can handle any format or difficulty that appears.
