Welcome to today’s CompTIA Network+ practice test!

This practice test uses our new UI!

Today’s practice test is based on Subdomain 2.1 (Explain characteristics of routing technologies) 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 2.1 #01
10 questions • Single best answer
Question 1
A network administrator at a regional hospital needs to ensure that traffic destined for a specific remote subnet always takes a predetermined path through the network. The administrator manually adds an entry to the routing table specifying the next-hop address for that subnet. Which type of routing is being used in this scenario?
    Question 2
    A junior network engineer reviewing a core router's configuration notices that two routing protocols have learned paths to the same destination network. The router is forwarding traffic using the OSPF-learned route instead of the EIGRP-learned route. Which routing concept explains why the router prefers the OSPF route?
      Question 3
      The IT team at a logistics company is deploying a routing protocol that will manage traffic between their corporate network and two different internet service providers. They need a protocol designed specifically for exchanging routing information between separate autonomous systems. Which routing protocol should they implement?
        Question 4
        A help desk analyst receives a ticket reporting that internal users can browse the internet, but external users cannot reach the company's publicly accessible web server. The network team discovers that return traffic from the web server is not being translated back to the server's public IP address. Which technology is most likely misconfigured?
          Question 5
          A network architect at a managed services provider is designing a solution for a client whose small office has 50 workstations that all need internet access. The client has been assigned only a single public IP address by their ISP. Which technology allows all 50 workstations to share that single public IP address simultaneously?
            Question 6
            A technician is troubleshooting a routing issue and notices that the routing table contains two OSPF-learned routes to the same destination network with the same prefix length. The router is using one route over the other. Which factor does OSPF use to determine which of these two routes is the best path?
              Question 7
              Your organization is migrating to a new office building and the network team must configure a single physical router interface to route traffic for three separate VLANs. Each VLAN requires its own default gateway address. Which feature should the team configure on the router to accomplish this?
                Question 8
                The network team at a university data center is deploying two core routers that will serve as the default gateway for all campus VLANs. They want to ensure that if the primary gateway router fails, the secondary router seamlessly takes over without requiring any configuration changes on end-user devices. Which technology should they implement?
                  Question 9
                  A senior network engineer at an insurance firm is evaluating routing protocols for the company's internal network of 200 routers across 15 locations. The engineer needs a protocol that uses link-state advertisements, supports variable-length subnet masking, and operates within a single autonomous system. Which routing protocol best meets these requirements?
                    Question 10
                    A field technician at a telecommunications company is analyzing a router's routing table and sees two entries for the destination 10.20.0.0. One entry shows 10.20.0.0/24 learned via EIGRP, and the other shows 10.20.0.0/16 learned via OSPF. When a packet arrives destined for 10.20.0.50, the router forwards it using the EIGRP-learned /24 route. Which route selection principle explains this behavior?
