6 Free CompTIA Network+ N10-009 Network Operations Practice Questions with Answers

Sample Question 1 — Network Operations

You are tasked with improving the performance of a company's network. After reviewing the network documentation, you notice that several links between switches are nearing their bandwidth capacity. What is the most effective way to address this issue?

  1. A. Implement link aggregation to increase bandwidth between switches. (Correct answer)
  2. B. Replace all copper cables with fiber optics.
  3. C. Reconfigure the switches to use a different VLAN.
  4. D. Install additional switches to distribute the load.

Correct answer: A

Explanation: Link aggregation, also known as port trunking, allows multiple network connections to be combined into a single logical link, effectively increasing the bandwidth between switches without the need for additional hardware.

Sample Question 2 — Network Operations

While monitoring network performance, you notice a consistent increase in latency during peak hours. Which tool would best help you identify the source of the latency?

  1. A. Packet sniffer
  2. B. Network mapper
  3. C. Bandwidth analyzer (Correct answer)
  4. D. Ping utility

Correct answer: C

Explanation: A bandwidth analyzer can help identify which applications or devices are consuming the most bandwidth, allowing you to pinpoint the source of the latency during peak hours.

Sample Question 3 — Network Operations

Your company's network documentation is outdated. As you update it, which component is most crucial to include for effective network performance monitoring?

  1. A. Network topology diagrams (Correct answer)
  2. B. IP address allocation
  3. C. Device inventory list
  4. D. Service level agreements (SLAs)

Correct answer: A

Explanation: Network topology diagrams provide a visual representation of the network's structure, which is essential for understanding data flow and identifying potential bottlenecks or points of failure.

Sample Question 4 — Network Operations

After a recent power outage, several users report that they cannot access the network. What is the first step you should take to troubleshoot this issue?

  1. A. Check the status of the DHCP server.
  2. B. Verify the power status of network switches. (Correct answer)
  3. C. Inspect the cabling for physical damage.
  4. D. Reboot affected user devices.

Correct answer: B

Explanation: Since the issue occurred after a power outage, the first logical step is to verify that all network switches have power and are functioning correctly, as they are critical for network connectivity.

Sample Question 5 — Network Operations

A network technician is tasked with optimizing the network's backup and recovery processes. Which strategy will most effectively improve the recovery time objective (RTO)?

  1. A. Implementing incremental backups instead of full backups.
  2. B. Using cloud-based backup solutions.
  3. C. Deploying redundant systems and failover mechanisms. (Correct answer)
  4. D. Scheduling backups during off-peak hours.

Correct answer: C

Explanation: Deploying redundant systems and failover mechanisms ensures that critical services can continue to operate or be restored quickly in the event of a failure, thus improving the recovery time objective.

Sample Question 6 — Network Operations

You need to ensure that all network documentation is easily accessible and up-to-date. What is the best approach to achieve this?

  1. A. Store all documentation in a shared network drive.
  2. B. Use a version-controlled documentation system. (Correct answer)
  3. C. Print hard copies and distribute them to all IT staff.
  4. D. Email updates to the IT team regularly.

Correct answer: B

Explanation: A version-controlled documentation system allows multiple users to access, update, and track changes to documents, ensuring that the most current information is always available.
