Question 3

A home user complains that their internet is extremely slow during peak evening hours, but speed tests show fast results late at night. They have a cable modem connection. What is the most likely cause of this issue?

Accepted Answer

Bandwidth congestion from neighbors. Cable internet uses a shared medium, so bandwidth is divided among users in the same neighborhood, causing slowdowns during peak usage. DSL and fiber are typically dedicated lines, and satellite latency is constant. This is a common complaint with cable broadband.

Answer

The modem is overheating

Answer

A faulty Ethernet cable

Answer

The ISP is throttling video streaming

Question 4

A technician is configuring a new router for a client who has a fiber-optic internet connection. Which type of interface is most likely used to connect the router to the ISP's ONT (Optical Network Terminal)?

Accepted Answer

Ethernet (RJ45). Fiber-optic connections typically use an ONT that converts optical signals to electrical, and the router connects via Ethernet (RJ45). Coaxial is for cable, RJ11 for DSL, and fiber patch cables connect the ONT to the wall, not the router. Ethernet is the standard interface for modern fiber installations.

Answer

Coaxial (F-type)

Answer

RJ11 (phone jack)

Answer

Fiber patch cable (LC connector)

Question 5

A client in a dense urban apartment building wants internet service but cannot install a satellite dish due to HOA rules. They have a phone line but no cable TV outlet. Which connection type is most practical and cost-effective?

Accepted Answer

DSL. DSL uses existing phone lines and is widely available in urban areas, making it a practical choice. Cable requires a coaxial outlet, satellite is prohibited, and fiber may not be available in all apartment buildings. DSL offers a balance of availability and cost.

Answer

Cable broadband

Answer

Satellite

Answer

Fiber-optic

Question 6

A user reports that their internet connection drops out frequently, especially during rainstorms. They have a dish mounted on their roof. Which connection type are they most likely using?

Accepted Answer

Satellite. Satellite internet is susceptible to rain fade, where heavy rain attenuates the signal, causing dropouts. Fiber and cable are underground and unaffected by rain, while DSL uses phone lines. This symptom is classic for satellite connections.

Answer

Fiber-optic

Answer

Cable broadband

Answer

DSL

Question 7

A company is deploying VoIP phones and needs a connection with low latency and consistent speeds. They are choosing between cable broadband and fiber-optic. Which factor makes fiber the better choice?

Accepted Answer

Fiber provides symmetrical upload and download speeds. Fiber-optic provides low latency and symmetrical speeds, ideal for VoIP. Cable broadband can suffer from latency spikes due to shared bandwidth and has asymmetrical speeds. Fiber's dedicated connection ensures consistent call quality.

Answer

Fiber has higher download speeds

Answer

Fiber is less prone to electromagnetic interference

Answer

Fiber is cheaper than cable

Question 8

A technician is troubleshooting a DSL connection that keeps disconnecting. The modem shows the DSL light blinking. After checking the phone line, they find a filter is missing on a nearby phone handset. How does this cause the issue?

Accepted Answer

The missing filter allows voice frequencies to interfere with DSL frequencies. DSL requires a microfilter on every phone device to prevent interference from voice signals. Without it, the phone handset can cause noise that disrupts the DSL signal, leading to disconnects. This is a common DSL troubleshooting step.

Answer

The phone handset draws too much power from the line

Answer

The filter is needed to amplify the DSL signal

Answer

The phone handset creates a short circuit without the filter

Question 9

A client in a rural area has a cellular hotspot for internet but experiences frequent slowdowns. They want a more stable option that does not rely on wired infrastructure. Which technology should a technician recommend?

Accepted Answer

Fixed wireless. Fixed wireless access (FWA) uses a directional antenna to connect to a nearby tower, offering more stability than a mobile hotspot. Satellite has high latency, DSL requires phone lines, and cable requires coaxial. FWA is ideal for rural areas without wired options.

Answer

DSL

Answer

Cable broadband

Answer

Satellite

Question 10

An IT manager is comparing cable broadband and fiber-optic for a new office. They need the lowest possible latency for real-time financial trading applications. Which connection type should they choose, and why?

Accepted Answer

Fiber-optic, because it provides lower latency due to the speed of light in glass and dedicated bandwidth. Fiber-optic offers the lowest latency due to light transmission and dedicated bandwidth, essential for real-time trading. Cable broadband has higher latency due to shared bandwidth and signal conversion. Fiber's physical properties make it superior for latency-sensitive applications.

Answer

Cable broadband, because it uses coaxial cable which is faster than fiber

Answer

Fiber-optic, because it uses light signals and is not subject to electromagnetic interference

Answer

Cable broadband, because it has higher download speeds

Question 11

A customer reports that their internet connection drops frequently during rainstorms. They have a DSL line and a standard modem. Which factor most likely causes this issue?

Accepted Answer

Moisture in the copper line causes signal degradation.. DSL uses copper telephone lines that can degrade when moisture infiltrates the wiring or splices, leading to intermittent connectivity during rain. Unlike cable or fiber, DSL is particularly susceptible to weather-related signal loss due to aging infrastructure.

Answer

The modem's power supply is failing.

Answer

The customer's router is overheating.

Answer

The ISP is throttling the connection during storms.

Question 12

A small office uses a cable internet connection with a DOCSIS 3.0 modem. Users complain that speeds drop significantly during peak evening hours. What is the most likely cause?

Accepted Answer

Neighborhood congestion from shared bandwidth.. Cable internet uses a shared bandwidth model where all subscribers in a neighborhood contend for the same upstream and downstream channels. During peak usage, congestion reduces throughput for everyone, especially with older DOCSIS 3.0 modems.

Answer

The modem's firmware is out of date.

Answer

The office's router is overheating.

Answer

The ISP is performing maintenance every evening.

Question 13

A technician is setting up internet for a remote cabin that is 5 miles from the nearest road. No wired infrastructure exists. Which connection type is most practical for reliable, moderate-speed internet?

Question 14

A user reports that their fiber-to-the-home (FTTH) internet connection works but is slower than expected. The technician finds that the ONT (Optical Network Terminal) is connected to the router via a 100-meter Cat5e cable. What is the most likely issue?

Accepted Answer

The Ethernet cable is damaged or has a bad termination.. Cat5e cable is rated for 100 meters at 1 Gbps, so distance alone is not a problem. However, if the cable is damaged or poorly terminated, it can cause errors and speed reduction. The most common issue is a faulty cable or connection, not the distance itself.

Answer

The ONT is malfunctioning.

Answer

The Cat5e cable is too long for 1 Gbps.

Answer

The router is not configured for the correct speed.

Question 15

A customer wants to switch from cable internet to a fixed wireless ISP (WISP) to reduce costs. What is a critical requirement for the WISP installation?

Accepted Answer

A clear line-of-sight to the provider's tower.. Fixed wireless internet requires a clear line-of-sight between the customer's antenna and the provider's tower. Obstructions like trees or buildings can severely degrade or block the signal, making this the most important requirement.

Answer

A direct fiber connection from the provider's office.

Answer

A dedicated phone line for the modem.
