Master the CompTIA Network+ exam with our comprehensive Q&A collection. Review questions by topic, understand explanations, and build confidence for exam day.
Strategies to help you tackle CompTIA Network+ exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for CompTIA Network+
VLAN (Virtual Local Area Network) is correct because it allows a single physical network to be segmented into multiple logical networks, enabling traffic separation for security and performance optimization. NAT translates IP addresses between networks, VPN creates secure tunnels over public networks, and DHCP automatically assigns IP addresses, none of which provide logical network segmentation.
An IP address in the 169.254.0.0/16 range is an APIPA (Automatic Private IP Addressing) address, which is self-assigned when a DHCP client cannot reach a DHCP server. This indicates a DHCP service failure or connectivity issue between the client and DHCP server. The other options are incorrect as this specific range is reserved exclusively for APIPA use.
UDP/53 is correct because DNS primarily uses UDP port 53 for standard queries due to its speed and efficiency for small request-response transactions. DNS uses TCP/53 only for zone transfers or responses larger than 512 bytes. TCP/25 is SMTP, TCP/80 is HTTP, and UDP/69 is TFTP.
A site-to-site VPN is correct because it creates an encrypted tunnel between two network locations over the public internet, ensuring confidentiality and integrity of transmitted data. VLAN trunking carries multiple VLANs but doesn't encrypt traffic, port forwarding redirects traffic to internal hosts, and DMZ is a network segment for public-facing services, none of which provide encryption between sites.
A crossover cable is correct because it crosses the transmit and receive pairs, allowing two similar devices (like two switches) to communicate directly. Modern switches with Auto-MDIX can work with straight-through cables, but traditionally crossover cables are required. Straight-through cables connect dissimilar devices, rollover cables are for console connections, and coaxial cables are not used for modern switch interconnections.

Common questions about the exam format and questions
The CompTIA Network+ exam typically contains 50-65 questions. The exact number may vary, and not all questions may be scored as some are used for statistical purposes.
The exam includes multiple choice (single answer), multiple response (multiple correct answers), and scenario-based questions. Some questions may include diagrams or code snippets that you need to analyze.
Questions are weighted based on the exam domain weights. Topics with higher percentages have more questions. Focus your study time proportionally on domains with higher weights.
Yes, most certification exams allow you to flag questions for review and return to them before submitting. Use this feature strategically for difficult questions.
Practice questions are designed to match the style, difficulty, and topic coverage of the real exam. While exact questions won't appear, the concepts and question formats will be similar.
