CompTIA Network+ Practice Test for Subdomain 1.8 #03

Welcome to today’s CompTIA Network+ practice test!

This practice test uses our new UI!

Today’s practice test is based on Subdomain 1.8 (Summarize evolving use cases for modern network environments) 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 260610

10 questions • Single best answer

Question 1

A solutions architect at a technology company is designing a network for a smart building deployment. IoT sensors, HVAC controllers, and security cameras require network access but must be prevented from communicating with corporate workstations or servers. What network design practice should be applied?

A. Deploy a dedicated proxy server for IoT traffic B. Segment IoT devices on an isolated VLAN C. Apply QoS policies to throttle IoT traffic D. Enable NAT for all IoT devices

Question 2

A network engineer is evaluating an architecture that separates the control plane from the data plane. Routing and switching decisions are made by centralized software that pushes forwarding rules to network devices via a standardized API. What technology is described?

A. Software-defined networking (SDN) B. Intent-based networking C. MPLS traffic engineering D. Network functions virtualization

Question 3

An enterprise organization needs to enforce consistent security policies for users accessing cloud applications from branch offices, home networks, and mobile devices — without routing all traffic through a central data center. What framework delivers networking and security together as a cloud-native service?

A. NFV B. SASE C. Zero trust network access D. SD-WAN only

Question 4

An enterprise security team is adopting a model where every access request — whether from inside or outside the network — must be continuously authenticated, authorized, and verified. No device or user is inherently trusted based on network location. What security model is being implemented?

A. Perimeter-based security B. Defense in depth C. Zero trust architecture D. SASE

Question 5

A network engineer is presenting to leadership the technical reason why the organization must accelerate its transition to a newer IP addressing protocol. The primary driver is that 32-bit public addresses in the current protocol are nearly exhausted globally. What protocol adoption will solve this?

A. CGNAT as the long-term solution B. NAT64 as a permanent replacement C. IPv4 with VLSM throughout the enterprise D. IPv6

Question 6

A network operations team wants to deploy a system where network devices are configured automatically based on business policies expressed in high-level language, without requiring engineers to log into each device individually to apply CLI commands. What networking approach enables this?

A. Intent-based networking (IBN) B. SDN overlay networks C. MPLS traffic engineering D. SNMP-based polling and configuration

Question 7

A manufacturing company is deploying wireless connectivity across a factory floor that spans several acres. Traditional Wi-Fi coverage is inconsistent and the machinery control systems require sub-10ms latency. What technology should the network architect evaluate for this use case?

A. LoRaWAN B. 802.11ax Wi-Fi 6 C. Private 5G network D. Bluetooth mesh

Question 8

A content delivery company needs to run AI inference and video processing algorithms as close to the end user as possible to reduce the time data must travel to a central data center. What computing model enables workload execution at network access points near users?

A. Fog computing for IoT sensors only B. Edge computing C. Hyperconverged infrastructure D. Centralized cloud computing

Question 9

A DevOps team at a technology company manages all network device configurations as version-controlled text files stored in a code repository. Changes are automatically validated and deployed through a CI/CD pipeline without manual CLI intervention. What practice does this describe?

A. Intent-based networking B. Network functions virtualization C. Infrastructure as Code (IaC) D. SDN controller-based management

Question 10

A network security team wants a platform that automatically detects a compromised endpoint, isolates it from the network, updates firewall rules to block the associated threat indicators, and generates an incident report — all without requiring manual analyst action. What technology provides this capability?

A. Vulnerability scanner B. SIEM C. IDS D. SOAR
