How should I use these Cabling practice questions?

Read each scenario carefully and choose your answer before revealing the explanation. Then check why your choice was right or wrong. Repeat until the reasoning feels automatic.

Can I practise just Cabling questions in a focused session?

Yes — use the session launcher on this page to start a 10-, 20-, 30- or 50-question session drawn entirely from the Cabling domain.

Cabling practice questions

Practise identifying cable categories, connector types, and application scenarios for twisted pair, coaxial, and fiber optic cabling.

Courseiva uses original exam-style practice questions designed for learning and revision. The goal is to understand the concepts, recognise exam patterns, and improve through explanations — not memorise copied exam dumps.

What the exam tests

What to know about Cabling

Cabling tests your ability to identify, compare, and select twisted pair, coaxial, and fiber optic cable types and connectors.

Item 1 — Identify cable types: Cat5e, Cat6, Cat6a, Cat8, and their speed/distance limits.

Item 2 — Compare UTP vs STP: shielding, interference resistance, and grounding requirements.

Item 3 — Recognize fiber optic connectors: LC, ST, SC, and single-mode vs multimode.

Item 4 — Select proper cabling for specific network topologies and environmental conditions.

Why learners struggle

Why Cabling questions are commonly missed

Cabling questions are commonly missed because learners confuse cable categories (Cat5e vs Cat6) and connector types (RJ45 vs RJ11). Many also struggle with when to use UTP vs STP or single-mode vs multimode fiber.

·Cat5e vs Cat6 — speed and distance differences (max 15 words)
·UTP vs STP — shielding and grounding requirements (max 15 words)
·Single-mode vs multimode — core size and distance limits (max 15 words)
·RJ45 vs RJ11 — pin count and application (max 15 words)
·Coaxial vs twisted pair — impedance and use cases (max 15 words)
·Plenum vs PVC — fire rating and installation locations (max 15 words)

Watch out for

Common Cabling exam traps

▸Confusing Cat5e (1 Gbps) with Cat6 (10 Gbps up to 55m) speed ratings.
▸Assuming all RJ45 connectors work with any twisted pair cable gauge.
▸Mixing up coaxial connector types: BNC, F-type, and RCA for different applications.
▸Forgetting that fiber optic cables use light, not electricity, and require special termination.

Question 1easymultiple choice

Read the full Cabling explanation →

A customer reports that their new Gigabit Ethernet connection is only achieving 100 Mbps speeds. The cable run is about 75 meters through a drop ceiling. You verify the switch and NIC are both Gigabit-capable. Which cable issue is most likely causing the speed limitation?

Trap 1: The cable is a Cat5e patch cable.

Cat5e supports Gigabit Ethernet up to 100 meters, so this would not cause a 100 Mbps limit.

Trap 2: The cable is a Cat6a cable.

Cat6a exceeds Gigabit requirements, so it would not cause a speed drop to 100 Mbps.

Trap 3: The cable is a Cat6 cable.

Cat6 supports Gigabit Ethernet, so it would not cause a speed limitation.

Cabling questions

A customer reports that their new Gigabit Ethernet connection is only achieving 100 Mbps speeds. The cable run is about 75 meters through a drop ceiling. You verify the switch and NIC are both Gigabit-capable. Which cable issue is most likely causing the speed limitation?

A customer wants to connect two switches in different buildings about 150 meters apart. The link must support at least 1 Gbps. Which cabling solution is most appropriate?

A technician is troubleshooting a network where one workstation intermittently loses connectivity. The cable run is 85 meters and passes through a conduit with several sharp bends. The cable tester shows intermittent shorts. Which cabling issue is most likely?

A technician is installing a new network drop in a warehouse where the cable must run near high-voltage machinery. The run is 60 meters. Which type of cable should be used to minimize interference?

A small office is installing new network drops in a drop ceiling for employee workstations. The IT manager wants to minimize future troubleshooting. Which cabling practice should be followed during installation?

A customer reports that their new Cat6a installation passes a cable certifier test but the link only negotiates at 100 Mbps. The cable run is 90 meters and uses standard T568B terminations. What is the most likely cause of the speed limitation?

A user complains that their VoIP phone intermittently loses connectivity. The phone is connected to a switch via a 50-meter run of solid-core Cat6 cable. You suspect interference from nearby fluorescent lights. Which cabling characteristic is most relevant to this issue?

A technician is troubleshooting a network drop that was working yesterday but now has no link light at the switch. The cable run is 80 meters and passes through a conduit. Which tool should be used first to isolate the problem?

A company is upgrading its network to support 10 Gbps connections between server racks. The distance between racks is 25 meters. Which cabling standard is most appropriate for this upgrade?

A user reports that their computer connected to a wall jack works fine, but when they move the computer to a different desk and plug into a different wall jack, there is no network connectivity. The switch port shows no link light. What is the most likely cause?

A user reports intermittent network connectivity in an office that recently had a new ceiling installed. The network drop runs through the ceiling and is not in a conduit. What is the most likely cause of the intermittent connection?

A technician is installing a new network drop in a warehouse where there is high electromagnetic interference (EMI) from machinery. Which cable type should be used to minimize signal degradation?

A technician is troubleshooting a network drop that was working yesterday but now has no link light. The cable run is 90 meters and uses Cat5e. The patch cables and switch ports have been tested and are fine. What is the most likely issue?

A customer reports that their new Gigabit Ethernet connection is only achieving 100 Mbps speeds. The cable run is 75 meters through a drop ceiling and uses a Cat5e cable. What is the most likely cause of the speed limitation?

A technician is asked to run a new network cable from a patch panel to a cubicle 80 meters away. The cable must support at least 1 Gbps. The technician has Cat6 cable on hand. What is the maximum distance this cable will support for 1 Gbps?

A customer wants to connect two buildings that are 200 meters apart with a high-speed network link. Which cabling solution is most appropriate?
