6 Free CCNA IP Connectivity Practice Questions with Answers

Sample Question 1 — IP Connectivity

What command would you use to configure a default route pointing to gateway 192.168.1.1?

  1. A. ip route 0.0.0.0 0.0.0.0 192.168.1.1 (Correct answer)
  2. B. ip default-gateway 192.168.1.1
  3. C. ip route default 192.168.1.1
  4. D. default-route 192.168.1.1

Correct answer: A

Explanation: The command "ip route 0.0.0.0 0.0.0.0 192.168.1.1" creates a default route. The first 0.0.0.0 is the destination network, the second 0.0.0.0 is the subnet mask, and 192.168.1.1 is the next-hop gateway.

Sample Question 2 — IP Connectivity

Which routing protocol uses hop count as its metric and has a maximum hop count of 15?

  1. A. OSPF
  2. B. EIGRP
  3. C. RIP (Correct answer)
  4. D. BGP

Correct answer: C

Explanation: RIP (Routing Information Protocol) uses hop count as its metric and has a maximum hop count of 15. Any destination more than 15 hops away is considered unreachable, which limits RIP to smaller networks.

Sample Question 3 — IP Connectivity

A network engineer is troubleshooting connectivity issues between two routers. Router A can ping its directly connected interface, but cannot ping Router B's directly connected interface. Router B can ping its directly connected interface and Router A's directly connected interface. What is the MOST likely cause?

  1. A. A faulty cable between Router A and Router B.
  2. B. A misconfigured IP address on Router A's interface.
  3. C. A routing protocol issue preventing Router A from learning the route to Router B. (Correct answer)
  4. D. A firewall issue on Router B blocking ICMP traffic from Router A.

Correct answer: C

Explanation: Since Router B can ping Router A, the problem is not a cable issue (A) or a firewall issue on Router B (D). A misconfigured IP address on Router A (B) would prevent Router A from pinging its own interface. The most likely problem is a routing protocol misconfiguration, where Router A is unable to learn the route to reach Router B.

Sample Question 4 — IP Connectivity

Two networks, 192.168.1.0/24 and 192.168.2.0/24, need to communicate. Router R1 connects to both networks. What is the simplest method to achieve this?

  1. A. Configure OSPFv2 on both networks.
  2. B. Configure static routes on R1. (Correct answer)
  3. C. Configure EIGRP on both networks.
  4. D. Use a default gateway on each network.

Correct answer: B

Explanation: For only two networks, static routes are the simplest solution. OSPF and EIGRP are dynamic routing protocols that are more complex to configure and manage for such a small network. Default gateway will only allow hosts to reach the internet through R1, not reach each other. On R1, configure `ip route 192.168.1.0 255.255.255.0 GigabitEthernet0/0` and `ip route 192.168.2.0 255.255.255.0 GigabitEthernet0/1` (or the appropriate interfaces).

Sample Question 5 — IP Connectivity

A network administrator is configuring OSPF on a router. Which statement is true regarding OSPF cost calculation?

  1. A. Cost is calculated based on the bandwidth of the slowest link in the path.
  2. B. Cost is inversely proportional to the bandwidth. (Correct answer)
  3. C. Cost is directly proportional to the bandwidth.
  4. D. Cost is a fixed value, regardless of bandwidth.

Correct answer: B

Explanation: OSPF cost is inversely proportional to bandwidth. A higher bandwidth link has a lower cost. The reference bandwidth is 100 Mbps.

Sample Question 6 — IP Connectivity

A company uses NAT to translate private IP addresses to public IP addresses. Which of the following is a benefit of using NAT?

  1. A. Increased network security by hiding internal IP addresses. (Correct answer)
  2. B. Improved network performance by reducing routing table size.
  3. C. Simplified network administration by eliminating the need for IP address management.
  4. D. All of the above.

Correct answer: A

Explanation: NAT primarily provides security by hiding internal IP addresses from the public internet. While it can indirectly improve performance in some situations and simplify address management, these are not primary benefits.
