CompTIA Network+ Practice Test for Subdomain 2.1 #03

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 of the Day 260611

10 questions • Single best answer

Question 1

A senior network engineer at a telecommunications provider is designing routing for a new branch office. The branch has a single connection to headquarters and no need for automatic route discovery. The routing configuration should be simple and deterministic. What routing method is most appropriate?

A. OSPF with a default route B. BGP C. EIGRP D. Static routing

Question 2

A network engineer is configuring a link-state routing protocol that calculates the shortest path to all destinations using Dijkstra's algorithm, supports VLSM and classless routing, uses hello packets to discover neighbors, and scales well in large enterprise environments. Which protocol is this?

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

Question 3

An enterprise network team is connecting to two different internet service providers to ensure redundancy and optimal routing for outbound traffic. The routing protocol must support policy-based routing decisions and is designed for inter-domain route exchange. Which protocol should be configured?

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

Question 4

A router receives routes to the same destination network from both OSPF and a manually configured static route. To decide which route to install in the routing table, the router uses a numeric value that indicates the trustworthiness of each routing source. What is this value called?

A. Hop count B. Administrative distance C. Metric D. Cost

Question 5

A network engineer evaluates RIPv2 for use in a new network. He notes that while it is simple to configure, the protocol imposes a constraint that prevents it from being used in large networks. What is the primary scalability limitation of RIPv2?

A. Its maximum hop count of 15 limits the network diameter B. It requires manual neighbor configuration on all routers C. It does not support classless inter-domain routing D. It uses excessive CPU for Dijkstra calculations

Question 6

A network engineer must allow routes learned by OSPF on the internal enterprise network to be advertised into a BGP session with an ISP. What configuration step is required to move these routes between the two protocols?

A. Enable OSPF external LSA type 1 on all routers B. Configure a route reflector in the BGP AS C. Configure a summary default route in BGP D. Perform route redistribution from OSPF into BGP

Question 7

A network architect is selecting a routing protocol for an enterprise. She needs a Cisco-compatible protocol that uses a composite metric based primarily on bandwidth and delay, supports unequal-cost load balancing, and converges faster than OSPF in many topologies. Which protocol meets these requirements?

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

Question 8

A branch router must forward all traffic destined for networks it has no specific route to, directing it toward the headquarters router at 10.0.0.1. No specific routes exist for these unknown destinations. What configuration should be applied?

A. A default route (0.0.0.0/0) pointing to 10.0.0.1 B. A summary route for all internal subnets C. A static host route for 10.0.0.1 D. A floating static route with high administrative distance

Question 9

A router has two routes to the same destination: an OSPF-learned route with a cost of 20 and a static route configured with the default administrative distance. Which route will the router prefer and why?

A. The OSPF route, because it is dynamically learned B. Neither; the router load-balances between both routes C. The OSPF route, because it has the lower metric D. The static route, because it has a lower administrative distance

Question 10

A network engineer configures a router to distribute traffic across multiple equal-cost paths to the same destination prefix simultaneously, maximizing bandwidth utilization. What routing feature is being enabled?

A. Equal-cost multipath (ECMP) B. Route summarization C. Route redistribution D. Floating static routes
