10 Free CCNA 200-301 Sample Questions with Answers

Each question below includes 4 answer options, the correct answer, and a detailed explanation. These are real questions from the FlashGenius CCNA question bank.

Sample Question 1 — Automation and Programmability

A network engineer needs to automate the configuration of multiple Cisco switches using REST APIs. Which data format is most commonly used for exchanging data with Cisco's REST APIs?

  1. A. XML
  2. B. YAML
  3. C. JSON (Correct answer)
  4. D. CSV

Correct answer: C

Explanation: JSON (JavaScript Object Notation) is the most common data format used for exchanging data with Cisco's REST APIs. It's lightweight, human-readable, and easily parsed by both the client and the server. XML is also used but JSON is preferred for its efficiency. YAML and CSV are less commonly used in this context.

Sample Question 2 — Automation and Programmability

You are using the Cisco IOS-XE REST API to configure an interface. What HTTP method would you typically use to create a new configuration?

  1. A. GET
  2. B. PUT
  3. C. POST (Correct answer)
  4. D. DELETE

Correct answer: C

Explanation: The POST method is used to create new resources or configurations. GET retrieves information, PUT updates existing resources, and DELETE removes resources.

Sample Question 3 — 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 4 — 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 5 — IP Services

What is the purpose of DHCP Option 66?

  1. A. Default Gateway
  2. B. DNS Server
  3. C. TFTP Server (Correct answer)
  4. D. Domain Name

Correct answer: C

Explanation: DHCP Option 66 specifies the TFTP server name or IP address. This is commonly used by network devices like IP phones and switches to download configuration files or firmware updates during boot process.

Sample Question 6 — IP Services

Which protocol operates on UDP port 69?

  1. A. DHCP
  2. B. TFTP (Correct answer)
  3. C. SNMP
  4. D. DNS

Correct answer: B

Explanation: TFTP (Trivial File Transfer Protocol) operates on UDP port 69. It is a simple file transfer protocol commonly used for transferring configuration files and firmware to network devices.

Sample Question 7 — Network Access

What is the default administrative distance for OSPF routes?

  1. A. 90
  2. B. 100
  3. C. 110 (Correct answer)
  4. D. 120

Correct answer: C

Explanation: OSPF (Open Shortest Path First) has a default administrative distance of 110. This is higher than EIGRP (90) but lower than RIP (120), making OSPF routes preferred over RIP but not over EIGRP.

Sample Question 8 — Network Access

Which spanning tree protocol provides the fastest convergence?

  1. A. STP
  2. B. RSTP (Correct answer)
  3. C. PVST+
  4. D. MST

Correct answer: B

Explanation: RSTP (Rapid Spanning Tree Protocol) provides the fastest convergence, typically within seconds compared to the 30-50 seconds required by traditional STP. It achieves this through improved BPDU handling and port state transitions.

Sample Question 9 — Network Fundamentals

What is the maximum number of hosts that can be addressed on a /26 subnet?

  1. A. 62 (Correct answer)
  2. B. 64
  3. C. 126
  4. D. 254

Correct answer: A

Explanation: A /26 subnet uses 6 bits for host addressing (32-26=6). With 6 host bits, you can have 2^6 = 64 total addresses. Subtracting the network address and broadcast address leaves 62 usable host addresses.

Sample Question 10 — Network Fundamentals

Which OSI layer is responsible for end-to-end communication and error recovery?

  1. A. Session Layer
  2. B. Transport Layer (Correct answer)
  3. C. Network Layer
  4. D. Data Link Layer

Correct answer: B

Explanation: The Transport Layer (Layer 4) is responsible for end-to-end communication, error detection and recovery, flow control, and segmentation. TCP and UDP operate at this layer.
