Question No. 1

A technician is putting RJ45 connectors on Cat 6 cables. Which of the following tools should the technician use to secure the connectors?

ALoopback plug

BWire cutters

CPunchdown

DCrimping

Show Answer

Correct Answer: D

Question No. 2

A technician receives a S.M.A.R.T. error on a PC. When the technician presses the Esc key, the PC continues to turn on without any further issues. Which of the following should the technician do next?

AReplace the HDD.

BUpdate the PC's BIOS.

CClose the ticket.

DChange the NIC.

SM.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology):

SM.A.R.T. is a monitoring system integrated into modern HDDs and SSDs that detects and reports on various indicators of drive health and reliability.
A S.M.A.R.T. error indicates that the drive is showing signs of impending failure, even if the PC continues to boot and work normally for the time being.
Next Steps:
The appropriate action is to replace the hard drive (HDD) because a S.M.A.R.T. error is an early warning of possible hardware failure. Ignoring the warning could result in data loss if the drive fails completely.
The technician should also back up the user's data immediately to avoid losing critical information.
Incorrect Options:
B . Update the PC's BIOS: While keeping the BIOS updated is a good practice, it does not address the S.M.A.R.T. error, which is specific to the HDD.
C . Close the ticket: Closing the ticket without resolving the issue would be improper, as the S.M.A.R.T. error is a hardware problem that needs to be addressed to prevent future data loss or downtime.
D . Change the NIC: The NIC (Network Interface Card) is unrelated to the storage system and would not resolve a S.M.A.R.T. error.
Key Takeaway:
A S.M.A.R.T. error is a critical indicator of HDD health issues, and the drive should be replaced as soon as possible. Backing up data is also essential.

Question No. 3

Which internet connection type will most likely experience interference from rain?

AFiber

BCable

CSatellite

DDSL

Show Answer

Correct Answer: C

CompTIA A+ identifies satellite internet as the connection type most susceptible to weather-related interference, particularly rain, snow, and heavy cloud cover. This phenomenon is known as rain fade. Satellite connections rely on high-frequency microwave signals transmitted between a dish antenna at the customer site and an orbiting satellite. Moisture in the atmosphere absorbs and scatters these signals, causing latency spikes, reduced bandwidth, or complete signal loss during storms.

Fiber (A) uses light signals through glass fiber and is immune to electromagnetic and weather interference. Cable internet (B) uses shielded coaxial lines buried or run overhead, but rain does not affect signal quality in normal conditions. DSL (D) uses telephone lines, which may degrade with physical line issues, but not directly due to rain in the same way satellite is affected.

Thus, satellite internet is most likely to experience signal degradation during rain conditions.

Question No. 4

Which of the following could a user employ to maximize module bandwidth when selecting memory for a high-end gaming computer?

AError correction

BRAM voltage

CChannel configuration

DPhysical module size

Show Answer

Correct Answer: C

Channel configuration(e.g.,dual-channel,quad-channel) determines how memory modules communicate with the memory controller. Usingmatched pairs in dual- or quad-channel setupscan significantlyincrease memory bandwidth, improving performance especially for gaming and video-intensive tasks.

Option A (Error correction):ECC RAM is used in servers for reliability, not performance or gaming.

Option B (RAM voltage):Affects compatibility and overclocking but not bandwidth.

Option D (Physical size):Refers to module form factor (e.g., DIMM, SO-DIMM) and does not impact bandwidth.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.2: Given a scenario, install RAM types.

Question No. 5

Which of the following wireless frequency ranges involves the use of channels 1, 6, and 11?

A2.4GHz

B5GHz

C6GHz

D60GHz

Show Answer

Correct Answer: A

In Wi-Fi, the 2.4GHz band contains 14 total channels (depending on region), but only channels 1, 6, and 11 are considered non-overlapping in most countries. CompTIA A+ highlights the importance of selecting these channels to minimize interference, especially in environments with multiple wireless networks or access points.

The 2.4GHz band is narrower than 5GHz, causing adjacent channels to overlap significantly. Using channels 1, 6, and 11 prevents overlap and reduces signal interference, improving performance and stability.

5GHz (B) has many non-overlapping channels and does not use the 1/6/11 scheme. The 6GHz band (C) is part of Wi-Fi 6E and uses entirely different channel planning. The 60GHz band (D) supports short-range high-speed connections like WiGig, not traditional Wi-Fi channels.

Therefore, the 2.4GHz band is the correct answer.
