Which of the following connectors will uplink a new ISP cable modem to its wall jack?
- A . F-type
- B . LC
- C . RJ45
- D . Lightning
A
Explanation:
A cable modem connects to an ISP’s wall jack using a coaxial cable, and the standard connector used for coaxial connections is the F-type connector. According to CompTIA Core 1 (220-1201) networking hardware and cabling objectives, F-type connectors are specifically designed for coaxial cabling used in cable television and cable internet (DOCSIS) installations. These connectors screw onto the coaxial wall outlet and the cable modem, ensuring a secure physical connection and proper signal transmission.
An LC connector is a fiber-optic connector commonly used with single-mode or multimode fiber cables and is not associated with cable modems. An RJ45 connector is used for Ethernet networking and is typically used to connect the cable modem to a router or computer, not to the wall jack. Lightning is a proprietary Apple connector used for charging and data transfer on mobile devices and has no role in network uplinks.
CompTIA expects candidates to clearly distinguish between different cable types and connectors based on the service being installed. When the scenario involves a cable modem and ISP wall jack, the correct and standard connector is the F-type.

A technician wants to upgrade a computer to a new Windows version. The Windows Upgrade Advisor states that the computer is not compatible with the new Windows version due to a lack of TPM 2.0 support.
Which of the following should the technician do next?
- A . Enable the module in the UEFI BIOS.
- B . Install an HSM in the computer.
- C . Perform a clean Install of the new Windows version.
- D . Implement BitLocker on the computer.
A
Explanation:
TPM 2.0 (Trusted Platform Module) is often disabled by default in the UEFI BIOS. Enabling it is necessary to meet the requirements for certain Windows installations, including Windows 11.
Why Not B (Install an HSM): A Hardware Security Module (HSM) is a separate device used for cryptographic functions and is not related to TPM on the motherboard.
Why Not C (Perform a clean install): A clean installation will not bypass the TPM 2.0 requirement.
Why Not D (Implement BitLocker): BitLocker requires TPM but does not resolve its absence or lack of activation.

A technician is troubleshooting a desktop PC that is plugged into a UPS. The PC loses the system date/time after every power outage.
Which of the following should the technician do to resolve the issue? (Select two).
- A . Run a BIOS update.
- B . Swap out the RAM.
- C . Disable NTP in the OS.
- D . Repair the backup power source.
- E . Replace the CMOS battery
- F . Install a surge protector.
D,E
Explanation:
The system date/time is maintained by the CMOS battery when the PC is powered off. If this battery fails, time resets will occur. Additionally, since the system is connected to a UPS, ensuring the UPS is functioning correctly (i.e., the backup power source) is essential.

A drive for a RAID 1 array fails. Users are concerned that information could be lost.
Which of the following is the best way to manage the situation?
- A . Repairing and reinstalling the defective disk to recover any files
- B . Discarding the defective disk without further action
- C . Replacing the defective disk and syncing the new one so that all files are retained
- D . Finding the latest backup of the legacy server and restoring it to transfer the files
C
Explanation:
A RAID 1 array uses disk mirroring, meaning all data is written identically to two drives. When one drive fails, the other contains a complete, current copy of the data. CompTIA A+ emphasizes that RAID 1 is designed for fault tolerance, allowing continued operation even after a disk failure.
The correct action is to replace the defective drive and allow the RAID controller to rebuild (sync) the mirror onto the new disk. This restores redundancy and ensures ongoing data protection. The system can typically continue running during the rebuild process.
Option A is incorrect because attempting to repair a failed drive is unreliable and unnecessary―RAID 1 already provides a healthy copy.
Option B ignores the importance of restoring redundancy, leaving the system vulnerable to data loss if the remaining drive fails.
Option D (restore from backup) is unnecessary because RAID 1 already preserves the data.
Therefore, the best solution is to install a new drive and resynchronize the array, preserving all data with minimal disruption.
A user’s laptop keyboard is distorted and is no longer flat.
Which of the following components most likely failed?
- A . Battery
- B . RAM
- C . Keyboard
- D . HDD
A
Explanation:
Comprehensive and Detailed Explanation
CompTIA A+ describes swollen or warped laptop chassis components as a classic symptom of a
failing or swollen lithium-ion battery.
A swollen battery can:
Warp the keyboard
Push the bottom panel outward
Bend or distort the laptop frame
This is a safety hazard and requires immediate replacement.
Why the other answers are incorrect
B. RAM C Cannot cause physical warping.
C. Keyboard C May fail electronically, but does not physically deform itself.
D. HDD C Located away from the keyboard and cannot distort the chassis.
Final Answer A
A technician is putting RJ45 connectors on Cat 6 cables.
Which of the following tools should the technician use to secure the connectors?
- A . Loopback plug
- B . Wire cutters
- C . Punchdown
- D . Crimping
Which of the following cloud models exclusively utilizes a local data center?
- A . Private
- B . Public
- C . Hybrid
- D . Community
A
Explanation:
A Private Cloud is operated solely for a single organization. It is hosted on-premises or in a dedicated off-site data center, giving the company full control over data, security, and compliance often hosted in the organization’s own local data center.
Option B (Public): Hosted by third-party providers and shared by multiple clients.
Option C (Hybrid): Combines private and public cloud resources.
Option D (Community): Shared by several organizations with similar goals.

Which of the following has the best penetration through physical objects, such as walls?
- A . 2.4GHz
- B . 5GHz
- C . 6GHz
- D . NFC
A
Explanation:
A user turns on their laptop. The keyboard lights up, but the screen is black even after the user restarts the laptop.
Which of the following should a technician do next to troubleshoot the issue?
- A . Connect the laptop to an external monitor.
- B . Remove the device bezel.
- C . Plug in a laptop charger.
- D . Replace the laptop.
A
Explanation:
When the keyboard backlight turns on, the laptop is receiving power and at least partially completing its startup hardware initialization. A black internal display can be caused by multiple issues, including a failed LCD/backlight, a loose or damaged display cable, an incorrect display output selection, or a graphics subsystem problem. The best next troubleshooting step is to connect the laptop to an external monitor because it quickly isolates whether the problem is with the internal display assembly or with the system’s ability to generate video at all.
If the external monitor displays video normally, the GPU and motherboard are likely functioning, and the technician should focus on the laptop’s internal screen components such as the LCD panel, backlight, display cable, or connector seating―often accessed by removing the bezel only after confirming this. If the external monitor also shows no video, the issue is more likely related to graphics output, memory, motherboard, or firmware/POST problems, and further internal diagnostics are required. Plugging in a charger is reasonable if the device seems underpowered, but it does not directly test the video path. Replacing the laptop is not an appropriate “next step” in troubleshooting.
Users are complaining that the audio from a presenter is choppy and unintelligible.
Which of the following is causing the issue?
- A . Webcam
- B . Digitizer
- C . inverter
- D . Microphone
D
Explanation:
Choppy or unintelligible audio is typically caused by issues with the microphone, such as poor quality, hardware defects, or misconfiguration.
Why Not A (Webcam): The webcam handles video, not audio.
Why Not B (Digitizer): A digitizer relates to touchscreens, not audio.
Why Not C (Inverter): Inverters manage power for displays, not audio.
