Answer

DSL

Answer

Cable broadband

Answer

Cellular (4G/5G)

Question 2

A small business is moving to a new office that already has a fiber-optic termination point installed. They need the fastest symmetrical speeds for cloud-based applications. Which internet connection type should they choose?

Accepted Answer

Fiber-optic. Fiber-optic internet provides symmetrical upload and download speeds, ideal for cloud applications. Cable broadband offers high download speeds but slower uploads, while DSL and satellite are slower and often asymmetrical. Fiber is the best fit when the infrastructure is already in place.

DSL

Answer

Cable broadband

Answer

Satellite

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 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 5

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 6

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 7

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?

Accepted Answer

Satellite. Satellite internet is the only viable option for locations far from wired infrastructure because it requires only a clear view of the sky. DSL, cable, and fiber all depend on physical cabling that is not available in such a remote area.

Answer

DSL

Answer

Cable

Answer

Fiber optic

Question 8

A technician is troubleshooting a fiber optic connection where the ONT (Optical Network Terminal) has a red 'LOS' (Loss of Signal) light. The fiber cable appears intact. What should the technician check next?

Accepted Answer

Inspect and clean the fiber connector.. A red LOS light indicates no optical signal is reaching the ONT. Even if the cable looks intact, the most common cause is a dirty or damaged connector at the termination point. Cleaning the fiber end with a proper kit often resolves the issue.

Answer

Replace the ONT immediately.

Answer

Check the power supply to the ONT.

Answer

Reboot the router connected to the ONT.

Question 9

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 10

A technician is troubleshooting a DSL connection that syncs at only 1.5 Mbps when the plan is 10 Mbps. The line is 12,000 feet from the central office. What is the most likely cause?

Accepted Answer

The distance from the central office is too great.. DSL speed is highly dependent on distance from the central office; at 12,000 feet, signal attenuation is significant, and the maximum achievable speed drops well below 10 Mbps. This distance is likely beyond the optimal range for higher-speed DSL tiers.

Answer

The modem is defective.

Answer

The router's firmware needs updating.

Answer

The ISP is throttling the connection.

Question 11

A technician is configuring a new satellite internet connection for a rural home. After aligning the dish, the modem shows 'online' but the user cannot browse the web. What is the most likely cause?

Accepted Answer

The router's MTU setting is too high.. Satellite internet often uses a different MTU size than terrestrial connections, and the default MTU of 1500 can cause fragmentation issues. Additionally, the router must be configured for the satellite provider's specific MTU (usually around 1400-1450) to avoid packet loss.

Answer

The dish is not aligned properly.

Answer

The modem's firmware is outdated.

Answer

The user's browser is incompatible.

Question 12

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 13

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.

Answer

A satellite dish with a 2-foot diameter.

Question 14

A user's cable internet goes out completely after a power outage. The modem's power light is on, but the 'online' light is blinking. What is the most likely issue?

Accepted Answer

The modem is re-establishing its connection to the ISP.. After a power outage, cable modems often need to re-establish communication with the headend, which can take several minutes. The blinking online light indicates the modem is trying to sync with the provider's network, which is normal after a power loss.

Answer

The modem's firmware was corrupted during the outage.

Answer

The coaxial cable was damaged by the power surge.

Answer

The router's DHCP server failed.
