CompTIA Network+ Practice Test for Subdomain 1.8 #02

By /

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 for Subdomain 1.8 #02
10 questions • Single best answer
Question 1
A solutions architect at a financial services firm is evaluating networking solutions to streamline policy enforcement across 200 branch locations. The architect wants a solution where network behavior is defined by software policies applied globally from a single interface rather than configuring each device individually. Which characteristic of software-defined networking (SDN) best describes this capability?
    Question 2
    A network engineer at a logistics company is deploying 50 new branch routers as part of a wide area network expansion. The company requires that each newly installed device automatically receive its full configuration upon connecting to the network without requiring an on-site technician to manually configure it. Which SD-WAN feature enables this capability?
      Question 3
      A data center engineer at a cloud service provider needs to extend Layer 2 connectivity between two geographically separated data centers over an existing Layer 3 IP network. The solution must allow virtual machines in both locations to communicate as if they were on the same local network segment. Which technology is specifically designed to address this data center interconnect requirement?
        Question 4
        The security team at a healthcare organization is redesigning their network access model after a breach in which a compromised user account was able to reach systems far outside the scope of that user's role. The team wants an architecture that continuously verifies identity and context and grants users only the minimum access required to perform their specific function, regardless of network location. Which architecture best aligns with this approach?
          Question 5
          A network architect at a global retail company is tasked with consolidating their remote access VPN, cloud access security broker (CASB), secure web gateway (SWG), and firewall-as-a-service (FWaaS) capabilities into a single unified cloud-delivered platform. The company has thousands of remote workers requiring secure access to both cloud applications and internal resources. Which modern architecture framework is specifically designed to converge these networking and security capabilities?
            Question 6
            A network operations team at a university manages hundreds of switches and routers using an infrastructure-as-code platform. The team discovers that several devices have had their configurations manually altered by staff outside the approved change management process, causing discrepancies between actual running configurations and the desired state stored in the code repository. Which IaC concept specifically describes this condition?
              Question 7
              A network engineer at a regional internet service provider is helping a business client transition toward IPv6 while maintaining full connectivity with legacy IPv4 systems during the migration period. The client's servers must be natively reachable by both IPv4-only and IPv6-only clients simultaneously without any form of address translation. Which IPv6 transition mechanism best satisfies this requirement?
                Question 8
                A network manager at a retail chain is evaluating WAN solutions for 75 store locations. The existing infrastructure uses MPLS circuits at flagship stores, broadband internet at smaller locations, and LTE as a backup at remote sites. The manager needs a solution that can intelligently use all three transport types interchangeably and route traffic across whichever connection is most available and cost-effective at any given time. Which SD-WAN characteristic enables this capability?
                  Question 9
                  A network automation engineer at a software company uses an infrastructure-as-code platform to manage all network device configurations. The engineer needs to track every change made to configuration templates over time, allow multiple team members to collaborate on updates concurrently, and restore any device to a previous known-good configuration state if a new change causes an outage. Which IaC capability provides all of these functions?
                    Question 10
                    A junior network engineer at a telecommunications company is configuring a new network segment that will be deployed as IPv6-only to conserve address space. Several critical legacy backend servers on this segment cannot be upgraded and must remain IPv4-only. The engineer needs a mechanism that allows the IPv6-only hosts to initiate connections to these IPv4-only servers without deploying dual stack on each device. Which technology should the engineer implement?
