20+ practice questions focused on OSPF — 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 OSPF PracticeDrag and drop the following steps into the correct order to configure a Cisco switch as a DHCP relay agent with DHCP snooping, where the DHCP server is located on a remote router.
Explanation: First, the DHCP server must be properly configured on the router. Next, DHCP snooping is enabled globally on the switch to protect against rogue servers. Then, the specific client VLANs must be added to the snooping database. After that, the uplink interface to the DHCP server must be trusted to allow legitimate server responses. Finally, the ip helper-address command is placed on the client's SVI to forward DHCP broadcasts to the remote server.
Drag and drop the following steps into the correct order to configure a switch port for data and voice traffic.
Explanation: The correct order is: 1) Enter interface configuration mode, because all port-specific commands must be applied under the interface. 2) Set the port as an access port with 'switchport mode access'—a voice VLAN can only be assigned on an access port. 3) Assign the data VLAN with 'switchport access vlan' to ensure proper Layer 2 forwarding for data traffic. 4) Assign the voice VLAN with 'switchport voice vlan' so the IP phone's voice frames are tagged with the voice VLAN. 5) Enable PortFast with 'spanning-tree portfast' to immediately transition the port to forwarding, preventing DHCP timeouts for the phone and host.
Which 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.
A network administrator is configuring a new Windows workstation on a small office network that uses IPv4 addressing. The workstation must be able to communicate with devices on other subnets and resolve hostnames via a company DNS server at 10.10.10.5. The administrator has already set the IP address to 10.10.10.10 and the subnet mask to 255.255.255.0. Which additional parameter must be configured to meet both requirements?
Explanation: To communicate with devices on other subnets, the workstation needs a default gateway (router) to forward traffic beyond its local subnet. The IP address 10.10.10.10 with subnet mask 255.255.255.0 places it in the 10.10.10.0/24 network, so a default gateway (e.g., 10.10.10.1) is required for inter-subnet routing. Additionally, to resolve hostnames, the DNS server address must be explicitly configured; the company DNS server is at 10.10.10.5. Option A correctly provides both parameters.

Practice all OSPF questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of OSPF. 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
OSPF 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. OSPF is tested as part of the CCNA 200-301 v2 blueprint. Practicing with targeted OSPF questions ensures you can handle any format or difficulty that appears.
Yes. Courseiva provides free 200-301 practice questions across all exam topics and domains. The platform includes topic-based practice, mock exams, missed-question review, bookmarked questions, and readiness tracking — no account required.
Difficulty is subjective, but OSPF is a high-priority exam concept tested in multiple ways — direct recall, scenario analysis, and command-output interpretation. Consistent practice is the best way to build confidence.
