Which of the following is used primarily for archiving data?
- A . PAN
- B . MAN
- C . SAN
- D . LAN
- E . WAN
C

Several users report that a projector routinely turns off in the middle of meetings and does not tum back on immediately. Users have to wait several minutes before the projector will turn back on. When the projector is on, the picture is clear and bright.
Which of the following is the most likely reason the projector is turning off?
- A . The video cable connecting the video source to the projector is failing.
- B . The bulb in the projector is failing.
- C . The projector is overheating and needs to be cleaned.
- D . The outlet that the projector is plugged into is faulty.
C
Explanation:
The projector is overheating and needs to be cleaned. A common cause of projector shutdown is overheating, which can be triggered by dust accumulation, blocked vents, or faulty fans. The projector has a thermal protection circuit that turns it off when the temperature reaches a certain level, and it will not turn back on until it cools down. To prevent this issue, the projector needs to be cleaned regularly and placed in a well-ventilated area. The video cable, the bulb, and the outlet are not likely to cause the projector to turn off intermittently.

A user is unable to connect to network resources. A technician discovers that the user’s device has an invalid static IP v dress.
Which of the following should the technician configure on the user’s device to request an IP address?
- A . SSH
- B . FTP
- C . DHCP
- D . DNS
C
Explanation:
DHCP (Dynamic Host Configuration Protocol) dynamically assigns IP addresses to devices on a network, resolving the issue of an invalid static IP address. Configuring the device to use DHCP allows it to request and receive a valid IP address automatically.
Why Not A (SSH): Secure Shell (SSH) is used for secure remote access, not IP address assignment.
Why Not B (FTP): File Transfer Protocol (FTP) is used for file transfers, not network configuration.
Why Not D (DNS): DNS resolves domain names to IP addresses but doesn’t assign IP addresses.

A user’s laptop has been slow to respond for the past few days. The user has run a virus scan, deleted temporary files, closed unnecessary programs, and rebooted the laptop, but the issue persists.
Which of the following steps should the technician take next?
- A . Perform a RAM upgrade.
- B . Replace the laptop’s hard drive.
- C . Bench test the laptop.
- D . Run a firmware update.
D
Explanation:
Firmware is a type of software that controls the hardware components of a device, such as the motherboard, hard drive, or keyboard. Firmware updates can improve the performance, stability, and compatibility of the device, as well as fix bugs and security issues. Running a firmware update can help to resolve the issue of a slow laptop, especially if the firmware is outdated or corrupted.
A user’s touch-screen tablet is having an issue with the screen orientation.
Which of the following is MOST likely causing this issue?
- A . The screen rotation is locked
- B . The screen protector on the tablet is damaged
- C . The touch-screen digitizer is malfunctioning
- D . The inverter is misconfigured
A
Explanation:
The screen rotation is locked. If a user’s touch-screen tablet is having an issue with screen orientation, it could be due to screen rotation being locked in device settings.
If the screen rotation is locked, the touch-screen tablet will not rotate the screen when the device is turned. This can usually be unlocked in the settings or by pressing a specific key combination. References: https://www.howtogeek.com/254132/how-to-enable-screen-rotation-on-windows-10/
A technician replaces a laptop hard drive with an M.2 SSD. When the technician reboots the laptop, the laptop does not detect the SSD.
Which of the following should the technician configure for the system?
- A . HSM
- B . Boot options
- C . UEFI settings
- D . TPM
C
Explanation:
UEFI stands for Unified Extensible Firmware Interface, and it is a type of firmware that controls the boot process of a computer. UEFI settings allow the technician to configure various aspects of the boot process, such as the boot order, the boot mode, and the security options. If the technician replaces a laptop hard drive with an M.2 SSD, they may need to adjust the UEFI settings to enable the system to detect and boot from the new drive.
A user reports that files are taking hours to transfer from a device to an external USB drive. The technician confirms that the device’s cables are connected and the correct USB port is being used.
Which of the following steps should the technician take next when troubleshooting the issue?
- A . Turn off all Bluetooth devices.
- B . Update the device drivers.
- C . Replace the USB drive.
- D . Replace the device’s USB port.
B
Explanation:
When a device is experiencing slow file transfers to an external USB drive and the physical connections are confirmed to be correct, the next step is to update the device drivers. Outdated or corrupt drivers can cause suboptimal performance and slow transfer speeds. Updating the drivers can resolve these issues and improve the device’s communication with the USB drive, leading to faster file transfers.

A video game developer is requesting a new desktop computer with eight sticks of memory. The developer wants the desktop computer to take advantage of all available memory bandwidth without sacrificing performance.
Which of the following would be the BEST solution?
- A . Triple-channel with DDR5 ECC RAM
- B . Quad-channel with DDR4 RAM
- C . Quad-channel with DDR5 SODIMM
- D . Dual-channel with DDR4 RAM
B
Explanation:
Quad-channel memory architecture allows the CPU to access four memory modules simultaneously, increasing the memory bandwidth and performance. DDR4 RAM is a type of memory that has higher speed and lower power consumption than DDR3. SODIMM is a smaller form factor of memory that is typically used in laptops, not desktops.
ECC RAM is a type of memory that can detect and correct errors, but it is more expensive and slower than non-ECC RAM. Triple-channel memory architecture is less common and less efficient than quad-channel.

A technician is building a budget PC with a dual-core CPU, onboard sound and graphics, and a single SSD.
Which of the following power supply wattage levels is the most appropriate?
- A . 400W
- B . 850W
- C . 1,000W
- D . 2,000W
A
Explanation:
A technician is setting up network printers in a new office building. The company wants all of the printers to be configured the same way for consistency. Some of the printers do not have an RJ45 port to connect to the network.
Which of the following does the technician need to enable so all of the printers can be connected to the network?
- A . Wireless
- B . Authentication
- C . PostScript
- D . USB
A
Explanation:
To connect printers without an RJ45 port to the network, the technician needs to enable wireless connectivity. By configuring the printers to connect to the network wirelessly, the company can achieve the desired consistency in printer configuration across the office. This approach allows printers without built-in wired network capabilities to be part of the network, facilitating shared access and remote printing functionalities.
Reference: CompTIA A+ Core 1 (220-1101) Exam Objectives, Section 2.3 Networking, specifically the information on configuring and troubleshooting wireless connectivity for devices, which includes enabling and securing wireless connections on network printers.
General understanding of network printer configuration options, including the use of wireless connectivity to integrate printers into a network environment, particularly when wired connections are not feasible.
