CompTIA Network+ Practice Test for Subdomain 2.1 #02

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 #02

10 questions • Single best answer

Question 1

A network technician at a regional logistics company is configuring gateway redundancy for warehouse workstations. If the primary gateway router fails, workstations must fail over to a standby router immediately without any manual reconfiguration on the client side. Which technology should the technician implement to meet this requirement?

A. Spanning Tree Protocol (STP) B. Hot Standby Router Protocol (HSRP) C. Open Shortest Path First (OSPF) D. Port Address Translation (PAT)

Question 2

A network engineer at a mid-sized enterprise reviews the routing table on a core router and finds that both OSPF and EIGRP have provided routes to the 10.1.1.0/24 network. The router has installed the EIGRP route into the forwarding table. Assuming no manual configuration has altered default values and the metrics are equivalent, which factor caused the router to prefer EIGRP over OSPF?

A. EIGRP supports classless routing while OSPF does not B. EIGRP has a lower administrative distance than OSPF C. EIGRP uses fewer router hops to reach the destination D. OSPF requires more bandwidth overhead than EIGRP

Question 3

A junior network engineer is troubleshooting why a branch office can no longer communicate with the corporate datacenter following a recent WAN topology change. Investigation reveals a route to the datacenter subnet is present in the router's table but points to a next-hop that no longer exists. No routing protocol is running on this router. Which characteristic of the routing configuration is the MOST likely root cause?

A. Static routes have a higher administrative distance than dynamic routes and were overridden B. Static routes do not automatically update when the network topology changes C. Static routes cannot coexist with NAT on the same interface D. Static routes only support IPv4 addressing and cannot handle modern traffic

Question 4

A network engineer at a university is evaluating dynamic routing protocols for a campus redesign. The protocol must build a complete map of the network topology using link-state advertisements, support hierarchical design through the use of areas to reduce routing overhead, and calculate shortest paths using Dijkstra's algorithm. Which routing protocol matches all of these characteristics?

A. RIPv2 B. EIGRP C. OSPF D. BGP

Question 5

The network team at a large enterprise is connecting their organization to two separate internet service providers for redundancy and traffic engineering purposes. The team needs a routing protocol capable of exchanging routing information between different autonomous systems and enforcing path selection policies based on business agreements. Which protocol is specifically designed for this use case?

A. OSPF B. EIGRP C. BGP D. RIPv2

Question 6

A network administrator at a small business needs to provide internet access for 75 internal workstations using a single public IP address assigned by the ISP. The solution must allow all workstations to initiate outbound connections simultaneously by tracking each session using unique port number assignments. Which technology meets this requirement?

A. Static NAT B. Dynamic NAT with an IP address pool C. Port Address Translation (PAT) D. First Hop Redundancy Protocol (FHRP)

Question 7

A router has the following entries in its routing table: 10.10.0.0/16, 10.10.5.0/24, and 0.0.0.0/0. A packet arrives with a destination IP address of 10.10.5.75. Which route will the router use to forward this packet?

A. 0.0.0.0/0, because the default route matches all destination addresses B. 10.10.0.0/16, because it was installed in the routing table first C. 10.10.5.0/24, because it is the longest matching prefix for the destination D. The router will drop the packet because multiple matching routes create an ambiguous forwarding decision

Question 8

A network engineer at a Cisco-based enterprise needs a dynamic routing protocol that uses a composite metric incorporating both bandwidth and delay by default, supports unequal-cost load balancing across multiple paths, and converges significantly faster than traditional distance-vector protocols. Which protocol best satisfies all of these requirements?

A. RIPv2 B. OSPF C. EIGRP D. BGP

Question 9

A network administrator is implementing inter-VLAN routing using a single physical router port connected to an 802.1Q trunk link on a Layer 2 switch. The administrator configures multiple logical interfaces on the single physical port, each with a unique IP address and VLAN assignment, to route traffic between VLANs. What are these logical divisions of a physical interface called?

A. Loopback interfaces B. Switched virtual interfaces (SVIs) C. Subinterfaces D. Virtual routing and forwarding (VRF) instances

Question 10

The IT team at a medical clinic needs to publish an internal web server to internet clients. External clients must always be able to reach the server using the same, predictable public IP address regardless of when the connection is initiated. The server's private IP is 172.16.10.20 and the clinic owns a small block of public IPs. Which NAT configuration is most appropriate for this requirement?

A. Dynamic NAT using an IP address pool B. Port Address Translation (PAT) C. First Hop Redundancy Protocol (FHRP) with a virtual IP D. Static NAT with a permanent one-to-one mapping
