CompTIA Network+ Practice Test for Subdomain 1.3 #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 1.3 (Summarize cloud concepts and connectivity options) 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 260605
10 questions • Single best answer
Question 1
A cloud infrastructure engineer at a startup uses a cloud service where the provider manages the underlying infrastructure, operating system, middleware, and runtime environment. The development team only writes application code and deploys it to the platform. Which cloud service model is being used?
    Question 2
    An enterprise hosts proprietary trading applications on infrastructure it owns in its own data center while also using a public cloud provider to handle capacity overflow during peak trading periods. What cloud deployment model does this describe?
      Question 3
      A cloud security architect needs to deploy workloads in the cloud within a logically isolated network segment that has its own defined IP address ranges, subnets, and routing policies, separate from other customers. What cloud networking construct should be used?
        Question 4
        A financial institution requires connectivity to its cloud provider with guaranteed bandwidth, predictable latency, and no traffic traversing the public internet. Which connectivity option meets these requirements?
          Question 5
          A cloud administrator needs to control inbound and outbound traffic to individual virtual machine instances within a VPC based on source IP address and port number. What cloud construct should be configured?
            Question 6
            A cloud architect distinguishes between a cloud system's ability to instantly add compute resources in response to an unexpected traffic spike versus its ability to grow capacity through planned provisioning over months. What term describes the ability to dynamically add and remove resources in real time based on demand?
              Question 7
              A network engineer is designing a cloud-native architecture where traditional hardware network appliances — such as firewalls and load balancers — are replaced with software instances running on standard x86 servers. What networking concept describes this approach?
                Question 8
                A cloud provider hosts hundreds of enterprise customers on the same underlying physical infrastructure. Each customer's data and workloads are logically isolated from others, sharing compute, storage, and networking resources. What cloud characteristic does this describe?
                  Question 9
                  A cloud administrator needs to allow virtual machine instances in a private subnet to initiate outbound connections to the internet — such as for software updates — while preventing any unsolicited inbound connections from the internet. What component enables this?
                    Question 10
                    A cloud architect is configuring a public subnet in a VPC and needs to ensure that instances within the subnet can send and receive traffic directly to and from the internet. What component must be attached to the VPC and referenced in the subnet's route table?
