CompTIA Network+ Practice Questions

Master the Network Operations Domain

Test your knowledge in the Network Operations domain with these 10 practice questions. Each question is designed to help you prepare for the CompTIA Network+ certification exam with detailed explanations to reinforce your learning.

Question 1

An organization is planning to upgrade its network infrastructure. Which type of documentation should be reviewed to ensure the new design will meet current and future performance requirements?

A) System audit logs

B) Capacity planning reports

C) Incident management records

D) User training manuals

Show Answer & Explanation

Correct Answer: B

Explanation: Capacity planning reports provide insights into the current and projected network resource usage, helping to ensure that the new network design will meet performance requirements. These reports are crucial for planning upgrades that accommodate future growth and increased demand.

Question 2

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)?

A) Implementing incremental backups instead of full backups.

B) Using cloud-based backup solutions.

C) Deploying redundant systems and failover mechanisms.

D) Scheduling backups during off-peak hours.

Show Answer & Explanation

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.

Question 3

Your company’s network uses both IPv4 and IPv6. Recently, users have reported connectivity issues. You suspect a problem with the DNS server configuration. Which tool would you use to verify DNS resolution for both IPv4 and IPv6 addresses?

A) ping

B) traceroute

C) dig

D) netstat

Show Answer & Explanation

Correct Answer: C

Explanation: The 'dig' command is useful for querying DNS name servers and can provide information about DNS resolution for both IPv4 (A records) and IPv6 (AAAA records).

Question 4

While reviewing network performance reports, you notice that the bandwidth usage is consistently near maximum capacity. What is the most effective strategy to address this issue?

A) Implement a bandwidth cap on all users

B) Upgrade the network infrastructure to higher capacity links

C) Restrict access to non-essential websites

D) Increase the DHCP lease time to reduce requests

Show Answer & Explanation

Correct Answer: B

Explanation: Upgrading the network infrastructure to higher capacity links is the most effective long-term solution to address bandwidth constraints. While restricting access to non-essential websites might provide temporary relief, it does not address the root cause of capacity issues.

Question 5

After a network outage, you need to review historical performance data to determine the cause. Which type of network documentation would be most useful in this scenario?

A) Network topology diagrams

B) Configuration files

C) Performance logs

D) Access control lists

Show Answer & Explanation

Correct Answer: C

Explanation: Performance logs provide historical data about network performance, which can be analyzed to identify patterns or anomalies that led to the network outage.

Question 6

A network administrator needs to ensure that a backup of the router configuration is performed before making changes. Which command would be used to back up the configuration on a Cisco router?

A) copy running-config startup-config

B) copy running-config tftp

C) backup running-config

D) save configuration

Show Answer & Explanation

Correct Answer: B

Explanation: The command 'copy running-config tftp' is used to back up the current running configuration of a Cisco router to a TFTP server, ensuring a backup is available before making changes.

Question 7

During a routine network audit, you discover that the network monitoring tool is not capturing all traffic data. What is a likely cause of this issue?

A) The monitoring tool is not configured to use SNMP.

B) There is a misconfigured VLAN on the network.

C) The monitoring tool lacks sufficient bandwidth.

D) Port mirroring is not enabled on the switches.

Show Answer & Explanation

Correct Answer: D

Explanation: Port mirroring must be enabled on network switches to send a copy of network traffic to the monitoring tool. Without it, the tool cannot capture all traffic data.

Question 8

You need to ensure that your network can recover quickly from a hardware failure. Which of the following strategies should be implemented?

A) Implementing load balancing

B) Creating a redundant network topology

C) Using network segmentation

D) Enabling QoS on routers

Show Answer & Explanation

Correct Answer: B

Explanation: Creating a redundant network topology ensures that there are alternate paths for data to travel in case of hardware failure, improving network resilience.

Question 9

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

A) Store all documentation in a shared network drive.

B) Use a version-controlled documentation system.

C) Print hard copies and distribute them to all IT staff.

D) Email updates to the IT team regularly.

Show Answer & Explanation

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.

Question 10

A company wants to implement a disaster recovery plan that ensures minimal data loss. Which backup strategy should they use to achieve this?

A) Weekly full backups with daily differential backups.

B) Monthly full backups with daily incremental backups.

C) Real-time data replication to a secondary site.

D) Daily full backups stored offsite.

Show Answer & Explanation

Correct Answer: C

Explanation: Real-time data replication to a secondary site ensures that data is continuously updated and available, minimizing data loss in the event of a disaster.
