Overview

About the exam

CompTIA Network+ (N10-009) validates networking skills essential for designing, configuring, managing, and troubleshooting wired and wireless networks. It's vendor-neutral, covering concepts applicable to any network infrastructure.

Network+ is a critical stepping stone between A+ and advanced networking or security certifications. The N10-009 version emphasizes modern networking including software-defined networking, cloud connectivity, and network automation.

Network Implementation1 / 5

A network engineer is implementing content caching at the network edge. Which device stores frequently requested web content locally to reduce bandwidth consumption and improve response times for users?

AlexFull explanation from Alex

A forward proxy with caching sits between internal clients and external web servers, intercepting HTTP requests and storing copies of frequently accessed content locally. Cache hits are served directly from the proxy, reducing WAN bandwidth and improving response times. Per RFC 7234 (HTTP Caching), caching proxies use Cache-Control headers, ETags, and freshness lifetimes to determine when cached content is valid. A VPN concentrator provides encrypted tunnels, not caching. A load balancer distributes traffic across servers. A DNS resolver translates domain names to IPs. Only a forward caching proxy stores and serves web content locally to reduce bandwidth consumption. Ref: RFC 7234 (HTTP/1.1 Caching).

Network Operations2 / 5

A network administrator is reviewing configuration backup strategies. Which approach ensures that the MOST RECENT configuration can be restored if a device fails?

AlexFull explanation from Alex

Automated change-triggered configuration backups ensure the most recent device configuration is always recoverable. When a configuration management tool (e.g., Ansible, Oxidized, RANCID) detects a change, it immediately captures and versions the new config, stored off-device. Printing configs is impractical and outdated. Annual backups leave gaps — changes between maintenance windows are lost. Storing backups only on the device means a failure loses both config and backup. Best practice: automate on every change, store off-device with version history, and periodically test restores. For Cisco: copy running-config tftp sends config to a backup server. Ref: CompTIA Network+ N10-009 Objective 3.3, NIST SP 800-53 CM-6.

Network Implementation5 / 5

A network engineer needs to configure a switch port to carry traffic for VLANs 10, 20, and 30 between two switches. Which port type should be configured?

AlexFull explanation from Alex

Switch port types are fundamental to Network Implementation. Access port: belongs to a single VLAN, carries untagged traffic. Used for end devices (PCs, printers, phones). The switch adds the VLAN tag internally. Trunk port: carries tagged traffic for multiple VLANs using 802.1Q encapsulation. A 4-byte tag is inserted into each frame containing the VLAN ID (12-bit field, supporting 4094 VLANs). The native VLAN is sent untagged. Used for switch interconnections. Port channel: a logical aggregation of multiple physical ports (LACP). Provides bandwidth aggregation, not multi-VLAN support (though a port channel can be configured as either access or trunk). Mirror/SPAN port: copies traffic from other ports for monitoring. For the exam, 'carry multiple VLANs' = trunk, 'single VLAN for end device' = access.

Exam domains

What's on the exam

Network Troubleshooting is the single largest domain at 24%, followed closely by Networking Concepts at 23% and Network Implementation at 20%. Network Operations (19%) and Network Security (14%) round out the blueprint — Security is the smallest domain by a clear margin, but it still covers cryptographic basics, identity-based access controls, and attacks such as DDoS floods and ARP spoofing.

The exam weighs diagnosing a broken network almost as heavily as understanding how one is built: nearly half the questions sit in Troubleshooting and Implementation combined, both of which assume comfort with hands-on configuration and command-line tools rather than diagram-only familiarity. Security's low weight doesn't mean low difficulty — its questions are concentrated rather than spread thin, so gaps there are harder to compensate for elsewhere.

Exam blueprint: COMPTIA-NET

Networking Concepts23%

Explain the OSI reference model, compare common networking appliances and their functions, and summarize cloud connectivity concepts, ports/protocols, transmission media, and network topologies. Also covers IPv4 addressing and subnetting, and evolving network architectures such as SD-WAN, zero trust, and IPv6.

≈ 21 h

Network Implementation20%

Set up routing and switching - VLANs and spanning tree included - choose and secure the wireless gear that connects to it, and plan the physical build: racks, cabling, power, and environmental controls.

≈ 18 h

Network Operations19%

Keep network documentation and change records current across a device's lifecycle, monitor the network with tools like SNMP and log aggregation, plan for disaster recovery, run DHCP and DNS services, and compare the ways engineers connect in remotely to manage it all.

≈ 17 h

Network Security14%

Explain foundational network security concepts such as encryption, identity and access management, and regulatory compliance, summarize common network attacks like DDoS and ARP poisoning, and apply defenses such as device hardening and network access control.

≈ 13 h

Network Troubleshooting24%

Apply a structured troubleshooting methodology to identify and resolve network problems, and diagnose cabling, physical interface, switching, and routing issues. Also covers troubleshooting network performance problems and using command-line and hardware tools such as ping, traceroute, and cable testers.

≈ 22 h

Format

Exam format and question types

The exam draws up to 90 questions in 90 minutes, mixing multiple-choice, multiple-response, and performance-based questions (PBQs). PBQs put you inside a network scenario (configuring a device, reading a topology diagram, working through a connectivity problem) rather than asking you to recall a fact in isolation. The passing score is 720 on a scale of 100 to 900.

Questions

Frequently asked questions

How long is the CompTIA Network+ exam?

The CompTIA Network+ exam has 90 questions and a 90-minute time limit.

What is the passing score for CompTIA Network+?

The passing score for the CompTIA Network+ exam is 720 / 900.

Which pitfalls should I review when preparing for CompTIA Network+?

Topics to review include Subnetting, OSI Model, Troubleshooting Methodology, Wireless Standards. Work through examples to check that you understand the distinctions and can explain your answer.

Does CompTIA publish a Network+ pass rate?

No. CompTIA does not publish pass rates for any of its exams, so the percentages that circulate on forums are guesses rather than data. What is published is the scored requirement and the objectives, which is what preparation can actually be aimed at.

Which Network+ domains carry the most marks?

Network troubleshooting is the largest domain at 24%, with networking concepts at 23% and network implementation at 20%. Network operations takes 19% and network security 14%. Nearly half the exam is concepts plus troubleshooting, which is why memorising port numbers alone does not get people through.

Do you need A+ before Network+?

No. CompTIA recommends A+ and nine to twelve months of networking experience, but neither is required to book. The catalog budget is around 90 hours, and prior support work mostly shortens the concepts domain rather than the troubleshooting one.

How do you renew Network+?

Network+ is valid for three years and renews with 30 continuing-education units inside that window. Passing a higher-level CompTIA certification renews it as well, so Security+ or Cloud+ covers it.

How soon can you retake Network+?

The second attempt has no waiting period. Subsequent attempts require a 14-day gap, and CompTIA sets no maximum number of tries.
