CompTIA Network+ Practice Test for Subdomain 1.5 #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 1.5 (Compare and contrast transmission media and transceivers) 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 260607
10 questions • Single best answer
Question 1
A data center technician at a colocation facility needs to connect two switches 380 meters apart using fiber optic cabling. The link must support 10 Gbps and budget is limited. The run does not exceed the multi-mode distance limits at 10 Gbps. Which fiber type should be selected?
    Question 2
    A network engineer is specifying cabling for a new office build-out that will support 10 Gbps to every desktop. Horizontal cable runs are a maximum of 50 meters. Which is the minimum cable standard that reliably supports 10GBASE-T at this distance?
      Question 3
      A cable contractor is installing wiring for a cable television distribution system throughout a multi-tenant building. The medium must carry RF signals over moderate distances with low signal loss and good resistance to external electromagnetic interference. Which cable type is most appropriate?
        Question 4
        A network technician is connecting a new SFP transceiver module in a switch to a fiber patch panel. The transceiver uses the small, high-density fiber connector that has become the enterprise standard for SFP and SFP+ modules. Which fiber connector type is used?
          Question 5
          A data center network team wants to use a single fiber strand per link to carry both transmit and receive traffic simultaneously, using different optical wavelengths for each direction. Which transceiver technology enables this?
            Question 6
            A building contractor is installing network cabling through the air-handling plenum space above a drop ceiling in a commercial office building. Fire codes require that cable materials in these spaces meet specific combustion and smoke emission standards. Which cable type must be used?
              Question 7
              A network engineer is selecting a transceiver to install in a core switch port to support a 40 Gbps uplink. Which transceiver form factor supports 40 Gbps and higher port speeds?
                Question 8
                A manufacturing facility requires structured cabling to run alongside heavy industrial motors and high-voltage electrical distribution panels. Signal integrity is critical and electromagnetic interference from the equipment is a significant concern. Which cabling medium is inherently immune to EMI?
                  Question 9
                  A technician is documenting an older fiber patch panel and identifies a connector type that houses two fiber ports combined into a single compact housing, commonly used in space-constrained environments. Which fiber connector type is this?
                    Question 10
                    A network engineer is connecting two top-of-rack switches located adjacent to each other in the same data center cabinet. The links must support 10 Gbps and the distance is under 5 meters. He wants the lowest-cost and highest-density option without using fiber. Which cable type should be selected?
