A company issued smartphones to users who work from home. The devices are enrolled and configured within the company’s MDM, and hardening profiles were deployed to each device for greater security.
Which of the following services best enhances security for remote users accessing company resources? (Select two).
- A . Two-factor authentication
- B . Managed corporate applications
- C . Cloud data synchronization
- D . Automated device setup
- E . GPS location tracking
- F . PIN code enforcement
AF
Explanation:
Two-factor authentication (2FA) significantly enhances security by requiring two forms of verification before granting access to company resources, making it harder for unauthorized users to gain access even if they have one of the credentials. PIN code enforcement adds an additional layer of security by ensuring that devices are protected by a PIN, making physical access to the device more challenging for unauthorized users. While the other options provide various benefits, 2FA and PIN code enforcement directly enhance the security of remote users accessing company resources.

Which of the following should the label on a network jack faceplate refer to?
- A . MAC address
- B . Patch panel port
- C . Switch port in use
- D . VLAN identification
B
Explanation:
A network jack faceplate is a device that covers and protects the network jack or outlet on a wall or a floor. A network jack or outlet is a physical interface that allows a network cable, such as an Ethernet cable, to be plugged into a network device, such as a computer or a printer. A network jack faceplate usually has one or more ports that correspond to different types of network cables, such as RJ-45, RJ-11, or coaxial.
A label on a network jack faceplate should refer to the patch panel port that the network jack or outlet is connected to. A patch panel is a device that connects multiple network cables in an organized and convenient way. A patch panel has a number of ports that correspond to different cables, such as Ethernet, coaxial, or fiber-optic cables. A patch panel can help simplify the wiring and management of a network, as well as provide flexibility and scalability for adding or changing network devices.
By labeling the network jack faceplate with the patch panel port, the network technician can easily identify and trace the cable that is connected to the network jack or outlet. This can help to troubleshoot and resolve network issues, such as connectivity, performance, or configuration problems. It can also help to avoid confusion or errors when installing or modifying network cables.
A user has decided to build a new computer with parts purchased from a popular online vendor The user has referenced online resources to assemble the unit. However, when the user presses the power button, the new computer does not load the operating system’s installer. Instead, the onboard speaker beeps and immediately reports an issue on the screen.
Which of the following is the MOST likely issue with the new build?
- A . The user did not plug in the processor’s fan.
- B . The user did not apply thermal paste to the CPU.
- C . The user did not seat the GPU correctly.
- D . The user did not install the power supply.
A
Explanation:
If a computer is not booting and the onboard speaker emits beeps, it can indicate a hardware issue. One of the most common causes of beep codes is overheating, which can occur if the processor’s fan is not properly installed and running. The processor’s fan is responsible for cooling the processor and preventing damage to the internal components.
A technician is setting up a projector for a videoconferencing system.
When the user attempts to connect a laptop to the system, the system displays the following error message: no source found
The user tries multiple cables and inputs on the projector
Which of the following should the user try next?
- A . Check the bulb the projector and replace it with a new one.
- B . Check the display settings on the computer and set them to extend/duplicate.
- C . Replace the projector another known-good one and try again.
- D . Replace the video card on the machine that is plugged in to tie projector. as it has gone bad.
B
Explanation:
The user should check the display settings on the computer and set them to extend/duplicate. This will allow the computer to send the video signal to both the laptop screen and the projector. If the display settings are set to only show on one screen, then the projector may not detect any source.
According to the CompTIA Core1 objectives, one of the common display issues is no image on screen. A troubleshooting guide for projectors also suggests checking the display settings as a possible solution for no source found error.

Afield technician is responding to a ticket about an animated sign with double images. One image is stationary, and the other image is live.
Which of the following is the cause of the issue?
- A . Bad display cable
- B . Burned out bulbs
- C . Display burn-in
- D . Incorrect color settings
C
Explanation:
Display burn-in occurs when a static image is left on a screen for a long time, causing the pixels to wear out unevenly and retain a ghost image even when new content is displayed. This issue can result in double images, where the "burned-in" stationary image persists alongside new, live content. This problem is more common in older displays or those used for static signage. Replacing the display cable or adjusting color settings would not address the underlying cause of uneven pixel wear, and burned-out bulbs would likely result in a loss of image clarity or brightness, not double images.
Reference: Display burn-in is a well-documented phenomenon in display technology, particularly affecting screens used for signage with static elements.
A Microsoft Windows user is preparing to work in another country and needs to comply with corporate policy for data protection when copying files to portable media.
Which of the following solutions would MOST likely satisfy this requirement?
- A . A USB 3.1 flash drive with BitLocker to Go installed
- B . An SD memory card with NTFS
- C . An xD memory card with ext3
- D . A portable hard drive with FAT32
A
Explanation:
Using a USB 3.1 flash drive with BitLocker to Go installed is the best option for complying with corporate policy for data protection when copying files to portable media. References: CompTIA A+ Certification Exam Guide, Ninth Edition, Chapter 12
Which of the following is the MAXIMUM power PoE+ provides?
- A . 15.4W
- B . 30W
- C . 60W
- D . 95W
B
Explanation:
The earliest PoE switches from a few years ago generated 15 Watts per port (IEEE 802.3af). Today, most use the PoE+ standard (IEEE 802.3at), which generates up to 30 Watts per port. That’s plenty for most devices that people want to connect
A technician is installing the RAM for a graphs workstation.
Which of the following is special purpose memory used by graphic controllers?
- A . SRAM
- B . MicroDlMM
- C . VRAM
- D . Unbuffered DIMM
C
Explanation:
VRAM (Video Random Access Memory) is a special-purpose memory type used by graphics controllers to store image data that is displayed on the screen. VRAM is faster and more expensive than regular RAM, and it allows the graphics controller to access the image data directly without involving the CPU or the system memory. VRAM can improve the performance and quality of graphics-intensive applications, such as video editing, gaming, and 3D rendering.
