CompTIA Network+ Practice Test for Subdomain 3.4 #03

By /

Welcome to today’s CompTIA Network+ practice test!

This practice test uses our new UI!

Today’s practice test is based on Subdomain 3.4 (Given a scenario, implement IPv4 and IPv6 network services) from the CompTIA Network+ N10-009 objectives.

This beginner-level practice test is inspired by the CompTIA Network+ (N10-009) exam and is designed to help you reinforce key networking concepts on a daily basis.

These questions are not official exam questions, nor are they brain dumps, but they reflect topics and scenarios relevant to the Network+ certification. Use them to test your knowledge, identify areas for improvement, and build daily cybersecurity habits.

CompTIA Network+ Practice Test of the Day 260627
10 questions • Single best answer
Question 1
A systems engineer at a large retail chain is deploying DHCP for a new store location. The administrator must define the range of IP addresses the server is authorized to distribute to client devices on the subnet. Which DHCP component specifies this range?
    Question 2
    A network technician at a manufacturing plant must ensure a network printer always receives the same IP address from DHCP without configuring a static address on the device itself. The technician links the printer's MAC address to a fixed IP in the DHCP server. Which DHCP feature accomplishes this?
      Question 3
      A network engineer at a university is deploying a centralized DHCP server. Client devices on remote VLANs cannot receive addresses because DHCP broadcast traffic does not cross router interfaces by default. Which feature must be configured on the router to forward client requests to the server?
        Question 4
        A wireless administrator at a stadium venue needs to maximize available IP addresses during short-duration events where thousands of devices connect temporarily. Reducing the time a client holds a DHCP-assigned address before it is reclaimed would help. Which DHCP parameter should be adjusted?
          Question 5
          An IPv6 network engineer at a technology company configures end-devices to generate their own addresses using router advertisement prefixes combined with each device's interface identifier. No DHCPv6 server is required. Which IPv6 addressing mechanism is being used?
            Question 6
            A DNS administrator at a healthcare company is adding a new record that maps a server's fully qualified domain name to its 32-bit IPv4 address. Users will query this entry to resolve hostnames to IP addresses for web browsing. Which DNS record type is being created?
              Question 7
              A network engineer is configuring DNS for a dual-stack web server that must be reachable over IPv6. The DNS entry must return a 128-bit address when clients query the server's hostname. Which record type should be added?
                Question 8
                A government agency is concerned about attackers injecting forged responses to redirect users to malicious servers. The security team wants to implement cryptographic signatures on DNS records so resolvers can verify their integrity and authenticity. Which extension provides this protection?
                  Question 9
                  A privacy-focused ISP wants to prevent eavesdroppers from inspecting customer DNS queries by encapsulating them inside encrypted web traffic on port 443. This method blends name resolution traffic with normal browser activity, making inspection harder. Which protocol achieves this?
                    Question 10
                    A network administrator at a law firm is configuring DHCP for a subnet containing several manually configured servers and printers with static addresses. The administrator must prevent the DHCP server from assigning those specific addresses to dynamic clients. Which DHCP feature accomplishes this?
