CompTIA Network+ Practice Test for Subdomain 1.6 #02

Welcome to today’s CompTIA Network+ practice test!

This practice test uses our new UI!

Today’s practice test is based on Subdomain 1.6 (Compare and contrast network topologies, architectures, and types) 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 1.5 #02

10 questions • Single best answer

Question 1

A junior network engineer reviewing a network diagram notices that all access switches connect to a pair of aggregation switches, which in turn connect to core switches. The organization is migrating its data center to a modern architecture where any access switch can reach any other with equal and predictable latency. Which topology should the engineer recommend?

A. Three-tier hierarchical model, because it provides separation between core, distribution, and access functions B. Star topology, because endpoints connect to a central switch for simplified management C. Spine-and-leaf architecture, because every leaf switch connects to every spine switch for equal-hop, predictable latency D. Collapsed core design, because merging layers reduces the number of hops between endpoints

Question 2

A network architect at a cloud service provider is designing a fabric to optimize performance between microservices running across multiple servers in the same data center. Most traffic does not leave the data center and instead moves laterally between application servers. Which traffic flow term best describes this behavior?

A. North-south traffic, because the data flows from the application tier toward external users B. East-west traffic, because traffic moves laterally between servers within the same data center C. Unicast traffic, because each packet is addressed to a single specific server D. Anycast traffic, because multiple servers may respond to the same service request

Question 3

A network administrator is reviewing the three-tier hierarchical campus network design and is asked to explain the primary function of the distribution layer. Which answer correctly describes the distribution layer's role?

A. Providing physical switch ports for end-user workstations, IP phones, and printers B. Performing high-speed backbone switching between buildings and the data center without applying policy C. Aggregating access layer connections and enforcing policy through inter-VLAN routing, ACLs, and QoS D. Terminating WAN circuits from the Internet service provider at the campus edge

Question 4

A corporate IT team is designing a WAN topology for a company with a main headquarters and 12 branch offices. All branch-to-branch communication must route through headquarters, and the design should minimize the total number of WAN links required. Which topology best fits this requirement?

A. Full mesh, because every site connects directly to every other site for maximum redundancy B. Partial mesh, because some sites connect directly, reducing cost while improving resilience C. Star (hub and spoke), because each branch connects only to headquarters and all traffic routes through the central hub D. Spine-and-leaf, because it provides equal-latency connectivity between all sites

Question 5

An emergency services organization is designing a communications network where every site must maintain connectivity even if multiple links fail simultaneously. Cost is not a primary constraint. Which network topology provides the highest level of link redundancy for this requirement?

A. Star topology, because all nodes connect through a highly available central hub B. Full mesh topology, because every node connects directly to every other node C. Spine-and-leaf topology, because it provides dual-path connectivity within a data center D. Three-tier hierarchical model, because redundant links can be added at each layer

Question 6

Your organization has leased a dedicated fiber circuit between the main office and a colocation facility 15 miles away. The circuit connects only the two endpoints with no other devices sharing the link. Which network topology does this connection represent?

A. Partial mesh, because the circuit is one of several redundant paths between the two sites B. Hub-and-spoke, because the colocation facility acts as a central hub for branch connectivity C. Point to point, because the circuit provides a dedicated connection between exactly two endpoints D. Ring, because the fiber circuit forms a closed loop between the two facilities

Question 7

A network architect is designing the infrastructure for a medium-sized office with approximately 200 employees. The organization does not need a dedicated core layer, and budget constraints favor a simpler two-tier design. The architect decides to combine the core and distribution functions into a single tier. Which design does this describe?

A. Spine-and-leaf architecture, because it is a two-tier design used to simplify campus networks B. Full mesh topology, because combining layers reduces the number of required links C. Collapsed core design, because the core and distribution functions are merged into a single tier above the access layer D. Three-tier hierarchical model, because the distribution layer absorbs the core layer duties

Question 8

A network engineer at a university campus is explaining the purpose of the topmost layer in the three-tier hierarchical model to a new team member. Which statement correctly describes the core layer's primary function?

A. Enforcing security policies, applying ACLs, and performing inter-VLAN routing between campus segments B. Connecting end-user workstations, printers, and IP phones to the campus network via switch ports C. Providing high-speed, low-latency packet switching to transport traffic between distribution layer switches D. Aggregating branch office WAN connections and terminating circuits from the Internet service provider

Question 9

A network technician is asked to describe the overall topology of a corporate network where the headquarters uses a star topology internally, each branch office also uses an internal star arrangement, and all branches connect to headquarters via a hub-and-spoke WAN design. Which term best describes this overall network design?

A. Full mesh, because every site has a direct path to every other site B. Hybrid topology, because the design combines multiple topology types -- star within each site and hub-and-spoke at the WAN level C. Point to point, because each branch has a dedicated link to headquarters D. Ring topology, because the combination of star and hub-and-spoke creates a looped path

Question 10

An organization recently deployed a customer-facing web application on-premises. External users access the application over the Internet, and their requests pass through the company's firewall and load balancer before reaching the internal application servers. Which traffic flow term best describes the direction of this user-to-application traffic?

A. East-west traffic, because the data moves between the user's device and the application servers horizontally B. Lateral movement, because the traffic crosses multiple internal network segments C. North-south traffic, because the traffic flows between an external network and the internal data center D. Spine-to-leaf traffic, because the request traverses multiple network tiers before reaching the server
