Which of the following is the maximum distance Cat 5, Cat 5e, Cat 6, and Cat 6a cables can be ran?
- A . 295ft (90m)
- B . 328ft (100m)
- C . 361ft (110m)
- D . 394ft (120m)
B
Explanation:
The maximum distance that Cat 5, Cat 5e, Cat 6, and Cat 6a cables can be ran is 100 meters or 328 feet, according to the TIA/EIA standards. This is the maximum length for a cable segment, which is the distance between two devices, such as a switch and a computer, or a router and a printer. If the cable segment exceeds this length, the signal quality may degrade and cause errors or loss of data.
Therefore, it is important to measure the cable length before installation and use repeaters or extenders if necessary.

A user has noticed high CPU temperatures when gaming. The user would like to lower the CPU temperature, and cost is not an issue.
Which of the following should the user do to BEST cool the CPU while keeping noise to a minimum?
- A . Upgrade the thermal paste.
- B . Use a copper heat sink.
- C . Upgrade the CPU fan.
- D . Install liquid cooling.
D
Explanation:
Liquid cooling is a method of cooling the CPU by circulating a liquid through a closed loop that absorbs heat from the CPU and transfers it to a radiator. Liquid cooling is more effective and quieter than air cooling, which uses a fan and a heat sink. However, liquid cooling is also more expensive and complex to install. Upgrading the thermal paste, using a copper heat sink, or upgrading the CPU fan are ways to improve air cooling, but they will not lower the CPU temperature as much as liquid cooling.

- D . HDMI
A
Explanation:
Optical fiber is the type of cable that should be used to terminate ST connectors on each end. ST connectors are commonly used for fiber optic cables, which transmit data using light pulses. Coaxial, shielded twisted pair, and HDMI are not types of cables that use ST connectors, but different types of connectors and transmission methods.

CORRECT TEXT
A technician has set up a new conference room with a TV and a video soundbar. The technician wants to test the system with a conference call. During the test, the TV speaker produces sound, but the soundbar does not.
Which of the following is the MOST likely cause of the issue?
A The volume on the TV needs to be turned up.
B. The conference call needs to be unmuted for audio.
C. An incorrect HDMI cable is being used.
D. The TV’s HDMI-ARC port is not being used.
Explanation:
HDMI-ARC (Audio Return Channel) is an HDMI connection that allows audio to be sent from the TV to an external sound system, such as a soundbar. If the TV’s HDMI-ARC port is not being used, then the soundbar will not receive any audio from the TV and thus will not produce any sound. To resolve the issue, the technician should ensure that the TV’s HDMI-ARC port is being used to connect the TV to the soundbar.
A technician plans to upgrade a laptop’s RAM from 4GB to 16GB.
Which of the following should the technician do?
- A . Purchase the same architecture of RAM.
- B . Configure the laptop’s BIOS settings for the RAM upgrade.
- C . Purchase RAM with the same CAS latency.
- D . Purchase the same brand of RAM.
A
Explanation:
The most important factor to consider when upgrading a laptop’s RAM is the architecture of the RAM, which determines the type, speed, and capacity of the memory modules. The architecture of the RAM must match the architecture of the laptop’s motherboard and processor, otherwise the RAM will not be compatible or function properly. The architecture of the RAM includes the DDR generation (such as DDR3 or DDR4), the form factor (such as SO-DIMM), the pin count (such as 204 or 260), the voltage (such as 1.35V or 1.5V), and the frequency (such as 1600MHz or 2400MHz).
The other options are not as crucial or relevant for the RAM upgrade. The brand of the RAM does not
matter as long as the RAM meets the specifications of the laptop and is of good quality. The CAS
latency of the RAM is a measure of the delay between the memory controller requesting data and
the RAM delivering it, and it affects the performance of the RAM. However, the CAS latency is not a
fixed value and can vary depending on the frequency and voltage of the RAM. Therefore, purchasing
RAM with the same CAS latency is not necessary or sufficient for compatibility. The laptop’s BIOS
settings are usually configured to automatically detect and adjust to the RAM upgrade, and do not
need to be manually changed by the technician.

A user’s laptop will not turn on for a meeting in a conference room. However, the laptop turns on correctly when connected to the external monitor, mouse, and keyboard at the user’s desk.
Which of the following should a technician do to ensure that the laptop functions everywhere in the office?
- A . Reinstall the laptop’s operating system.
- B . Enable a remote desktop account.
- C . Issue a peripheral set for use in the conference room.
- D . Replace the laptop’s battery.
D
Explanation:
A laptop’s battery is the component that provides power to the laptop when it is not connected to an external power source, such as a wall outlet or a docking station. A laptop’s battery can wear out over time, losing its capacity and ability to hold a charge. This can cause the laptop to not turn on or shut down unexpectedly when it is not plugged in.
According to some web search results, some signs and symptoms of a failing laptop battery are:
• The laptop does not turn on or turns off suddenly when it is not connected to an external power source
• The laptop shows a low battery warning or a red X over the battery icon even when it is fully charged
• The laptop takes longer to charge or does not charge at all
• The laptop feels hot or the battery bulges or leaks
To fix this issue, the technician should replace the laptop’s battery with a new one that is compatible with the laptop model and specifications. The technician should also dispose of the old battery properly, following the environmental and safety guidelines.
Reinstalling the laptop’s operating system, enabling a remote desktop account, or issuing a peripheral set for use in the conference room are not effective solutions for this issue, since they do not address the root cause of the problem, which is the faulty battery. Reinstalling the operating system may erase the user’s data and settings, and it may not improve the laptop’s performance or power management. Enabling a remote desktop account may allow the user to access their files and applications from another device, but it does not solve the problem of the laptop not turning on. Issuing a peripheral set for use in the conference room may provide the user with an external monitor, mouse, and keyboard, but it does not guarantee that the laptop will work without an external power source.
A user attempts to connect a laptop to a projector but receives the following message from the projector: Out of Range.
Which of the following needs to be addressed first?
- A . Change the resolution settings.
- B . Check the video cable and replace it if necessary.
- C . Set the computer’s display settings to extend/duplicate.
- D . Verify that the laptop video card driver is the most up-to-date version.
A
Explanation:
The most likely answer is A) Change the resolution settings.
The error “Out of Range” normally means that the resolution being output by the computer is not compatible with the projector. The resolution is the number of pixels that are displayed on the screen. If the resolution is too high for the projector, it may not be able to display the image correctly or at all12.
To resolve this issue, you should try lowering the resolution settings on your laptop to match the native resolution of the projector or a lower one.
You can do this by following these steps1:
• Right-click on an empty area of your desktop and select Display settings.
• Under Scale and layout, click on Display resolution and choose a lower option from the drop-down menu.
• Click Apply and then Keep changes.
• Reconnect your laptop to the projector and check if the image is displayed properly.
If changing the resolution settings does not help, you may need to check other factors, such as the video cable, the display settings, or the video card driver. However, these are less likely to cause the “Out of Range” error than the resolution settings.
The help desk received a ticket regarding Issues with a laser printer. The printer has had repairs previously for scanning Issues. Currently, the printed text is not adhering properly to the paper.
Which of the following should be replaced lo resolve this Issue?
- A . Fuser
- B . Waste container
- C . Roller
- D . Toner
A
Explanation:
If the printed text is not adhering properly to the paper on a laser printer that has had repairs previously for scanning issues, the fuser should be replaced to resolve this issue. The fuser is a component of the printer that uses heat and pressure to fuse the toner onto the paper. If the fuser is not functioning properly, the toner may not adhere properly to the paper.
