CompTIA Network+ Practice Test for Subdomain 2.4 #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 2.4 (Explain important factors of physical installations) 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 260702
10 questions • Single best answer
Question 1
A data center facilities manager at a regional bank is designing the cabling infrastructure for a new building. The team needs a centralized termination point where ISP handoffs and internal backbone cabling from core switches converge for the entire facility. Which location describes this?
    Question 2
    A cabling technician at a university is planning horizontal cabling runs from each floor's wiring closet back to the central equipment room. Each closet aggregates connections from nearby workstations and uplinks to the building core. Which term describes each floor-level wiring closet?
      Question 3
      A network engineer is ordering a rack-mounted switch that occupies 2U of vertical space and must confirm it fits in the remaining cabinet space before purchase. The engineer measures the available vertical slots in the enclosure. Which physical specification is being evaluated?
        Question 4
        A data center technician is installing a new switch whose fans draw cool air in from the front port side and exhaust hot air out the rear. The technician must orient the device correctly so intake aligns with the cold aisle and exhaust faces the hot aisle. Which installation factor is being managed?
          Question 5
          A network administrator is reorganizing a wiring closet to simplify moves, adds, and changes. The team wants a central board where structured cabling from wall jacks terminates so switch connections can be reconfigured using short cables without disturbing runs inside the walls. Which component fulfills this role?
            Question 6
            A facilities engineer at a campus network is running fiber optic cables between buildings. The team needs an enclosure at each endpoint that organizes, protects, and allows cross-connections between the incoming fiber runs and the active networking equipment. Which component should be installed?
              Question 7
              A network engineer at a hospital is concerned that brief power interruptions will cause network switches and routers to reboot, disrupting critical patient monitoring systems. The team needs a device that provides immediate battery power during outages and allows for a graceful equipment shutdown. Which device should be installed?
                Question 8
                A data center operator is installing a rack containing twelve servers and needs to distribute power from a single high-amperage circuit to each device's individual power supply within the enclosure. Which device is designed for this function?
                  Question 9
                  A network administrator notices that equipment in a wiring closet is experiencing accelerated corrosion and intermittent failures despite room temperature readings appearing normal. An inspection reveals condensation forming on circuit boards. Which environmental factor is the primary cause?
                    Question 10
                    A facilities manager at a financial services firm is selecting a suppression system for the primary data center. The solution must extinguish fires quickly without leaving residue on servers, corroding components, or causing water damage to active equipment. Which suppression approach is most appropriate?
