Free N10-008: CompTIA Network Exam Questions and Answers
This exam retired on 21 May 2025. It was replaced by N10-009: CompTIA Network+ Exam. The questions here still cover most of the same ground, and the new exam’s own page has the current bank.
Replaces N10-007: CompTIA Network 2018. Questions from the earlier version are also in this bank.
CompTIA Network+ (N10-008) retired in December 2024 and was replaced by N10-009. Certifications earned before retirement stay valid for three years, and the two versions overlap enough that this bank is solid preparation for the current exam. N10-008 allowed 90 minutes for up to 90 questions — multiple choice, drag-and-drop and performance-based — with a pass mark of 720 on a 100–900 scale. Networking fundamentals carried 24% of the marks, troubleshooting 22%, implementations 19%, security 19% and operations 16%. CompTIA recommends A+ and nine to twelve months of hands-on experience beforehand.

Question #1
Branch users are experiencing issues with videoconferencing. Which of the following will the company MOST likely configure to improve performance for these applications?
Correct answer: C
Explanation
To improve performance for videoconferencing, the company should configure Quality of Service (QoS). This technology allows for the prioritization of network traffic, ensuring that videoconferencing traffic is given higher priority and therefore better performance. Link Aggregation Control Protocol (LACP), Dynamic routing, Network load balancer, and Static IP addresses are not directly related to improving performance for videoconferencing. References: • Network+ N10-007 Certification Exam Objectives, Objective 2.6: Given a scenario, implement and configure the appropriate wireless security and implement the appropriate QoS concepts.

Question #2
Which of the following BEST describes a network appliance that warns of unapproved devices that are accessing the network?
Correct answer: D
Explanation
IDS stands for intrusion detection system, which is a network appliance that monitors network traffic and alerts administrators of any suspicious or malicious activity. An IDS can warn of unapproved devices that are accessing the network by detecting anomalies, signatures, or behaviors that indicate unauthorized access attempts or attacks.

Question #3
A technician is troubleshooting a network switch that seems to stop responding to requests intermittently whenever the logging level is set for debugging. Which of the following metrics should the technician check to begin troubleshooting the issue?
Correct answer: B
Explanation
CPU utilization is a metric that measures the percentage of time a CPU spends executing instructions. When the logging level is set for debugging, the router may generate a large amount of logging data, which can increase CPU utilization and cause the router to stop responding to requests intermittently. References: • Network+ N10-008 Objectives: 2.1 Given a scenario, troubleshoot common physical connectivity issues.

Question #4
A technician is connecting multiple switches to create a large network for a new office. The switches are unmanaged Layer 2 switches with multiple connections between each pair. The network is experiencing an extreme amount of latency. Which of the following is MOST likely occurring?
Correct answer: C
Explanation
A broadcast storm is most likely occurring when connecting multiple unmanaged Layer 2 switches with multiple connections between each pair. A broadcast storm is a situation where broadcast packets flood a network segment and consume all the available bandwidth. It can be caused by loops in the network topology, where broadcast packets are endlessly forwarded by switches without any loop prevention mechanism. Unmanaged switches do not support features such as Spanning Tree Protocol (STP) or Rapid Spanning Tree Protocol (RSTP) that can detect and block loops.

Question #5
The following configuration is applied to a DHCP server connected to a VPN concentrator: There are 300 non-concurrent sales representatives who log in for one hour a day to upload reports, and 252 of these representatives are able to connect to the VPN without any Issues. The remaining sales representatives cannot connect to the VPN over the course of the day. Which of the following can be done to resolve the issue without utilizing additional resources?

Correct answer: A
Explanation
Decreasing the lease duration on the DHCP server will cause clients to renew their IP address leases more frequently, freeing up IP addresses for other clients to use. References: CompTIA Network+ Certification Study Guide, Chapter 3: IP Addressing.

Question #6
Which of the following is MOST likely to generate significant East-West traffic in a datacenter?
Correct answer: B
Explanation
East-West traffic refers to data flows between servers or devices within the same datacenter. When a hosted virtual server is duplicated to another physical server for redundancy, it generates significant East-West traffic as the data is replicated between the two servers. References: • Network+ N10-008 Objectives: 3.3 Given a scenario, implement secure network architecture concepts.

Question #7
An administrator is writing a script to periodically log the IPv6 and MAC addresses of all the devices on a network segment. Which of the following switch features will MOST likely be used to assist with this task?
Correct answer: B
Explanation
The switch feature that is most likely to be used to assist with logging IPv6 and MAC addresses of devices on a network segment is Neighbor Discovery Protocol (NDP). NDP is used by IPv6 to discover and maintain information about other nodes on the network, including their IPv6 and MAC addresses. By periodically querying NDP, the administrator can log this information for auditing purposes. References: • CompTIA Network+ Certification Study Guide, Exam N10-007, Fourth Edition, Chapter 2: The OSI Model and Networking Protocols, Objective 2.1: Compare and contrast TCP and UDP ports, protocols, and their purposes.

Question #8
A systems administrator needs to improve WiFi performance in a densely populated office tower and use the latest standard. There is a mix of devices that use 2.4 GHz and 5 GHz. Which of the following should the systems administrator select to meet this requirement?
Correct answer: B
Explanation
802.11ax is the latest WiFi standard that improves WiFi performance in densely populated environments and supports both 2.4 GHz and 5 GHz bands. 802.11ac is the previous standard that only supports 5 GHz band. 802.11g and 802.11n are older standards that support 2.4 GHz band only or both bands respectively.

Question #10
Which of the following factors should be considered when evaluating a firewall to protect a datacenter’s east-west traffic?
Correct answer: B
Explanation
When evaluating a firewall to protect a datacenter’s east-west traffic, it is important to consider traffic between VMs running on different hosts. This type of traffic is referred to as east-west traffic and is often protected by internal firewalls. By implementing firewalls, an organization can protect their internal network against threats such as lateral movement, which can be caused by attackers who have breached a perimeter firewall.
