NEW QUESTION # 28
A technician upgrades a PC with two DIMMs, for a total of 32GB.
After installing the two DIMMs, the user notices the OS is reporting only 16GB.
Which of the following tasks should the technician perform to resolve the issue in the most rapid, cost-effective way possible?
- A. Update the OS to the latest version.
- B. Replace the faulty motherboard.
- C. Reinstall RAM in different slots.
- D. Roll back recent system updates.
Answer: C
Explanation:
Reinstalling RAM in different slots addresses possible issues with dual-channel configurations.
If not installed correctly, the system might not recognize the full capacity.
This solution is immediate and doesn't incur extra costs, unlike replacing hardware.
It reflects CompTIA A+ Core 1 exam objectives on hardware troubleshooting, specifically RAM installation and configuration.

NEW QUESTION # 30
Users working with large files back up the files to external hard drives. One user's files take longer to back up than other users' files. The user has tried backing up the files to other users' drives with the same results. Which of the following steps should the technician take first to correct this issue?
- A. Defragment the user's external hard drive.
- B. Replace the hard drive's USB cable.
- C. Instruct the user to compress the files.
- D. Update the storage drivers on the user's system.
Answer: A
Explanation:
If a hard drive is heavily fragmented, file read/write operations can take significantly longer, causing slow backup speeds. Defragmenting the drive organizes the data for more efficient access.
Why Not A (Replace the hard drive's USB cable): A faulty cable would typically cause disconnections or errors, not just slower speeds.
Why Not C (Update the storage drivers): This might help if the issue is with system drivers, but the described symptoms point to a fragmentation issue.
Why Not D (Compress the files): Compression reduces file size but does not address the root cause of the slow backups.
CompTIA A+ Exam Reference: Core 2 (220-1102), Section 3.1, storage troubleshooting.

* Option A (CPU): A failing CPU affects overall system performance but not specifically network speed.
* Option C (HDD): A slow hard drive causes application lag, but not poor network performance.
* Option D (RAM): Affects multitasking and speed, not network throughput.
CompTIA A+ Core 1 Exam Objective Reference:
* Objective 3.5: Given a scenario, troubleshoot problems related to wired and wireless networks.

NEW QUESTION # 36
A user installs a GPU and notices the screen resolution and picture quality are much lower than before the installation. Which of the following is most likely the cause of the issue?
- A. Theuser failed to install the appropriate OEM drivers.
- B. Thecomputer does not have enough RAM installed to support the GPU.
- C. TheGPU is not compatible with the user's motherboard.
- D. Thecomputer does not have a supported OS installed.
Answer: A
Explanation:
When a new GPU is installed and results in lower screen resolution and picture quality, it's often because the appropriate OEM (Original Equipment Manufacturer) drivers for the GPU have not been installed. Without these drivers, the operating system may revert to generic drivers that do not fully support the GPU's capabilities, leading to suboptimal performance. Installing the correct OEM drivers should resolve the issue and allow the GPU to function at its intended performance level.

NEW QUESTION # 38
A technician is reviewing the following network settings for a workstation that is having trouble accessing the internet:
Which of the following is causing the issue?
- A. The netmask is wrong.
- B. IPv6 should be used instead of IPv4.
- C. The workstation has the incorrect gateway.
- D. Networking was not configured using DHCP.
Answer: C
Explanation:
The IPv4 address (192.168.10.5) and the gateway address (192.168.1.1) are on different subnets. With a netmask of 255.255.255.0, the network part of the IPv4 address is 192.168.10.x, while the network part of the gateway address is 192.168.1.x. For the workstation to correctly route traffic to the gateway, both must be on the same subnet. The correct gateway address should be within the same subnet as the IPv4 address, such as
192.168.10.1.

NEW QUESTION # 42
A technician has been called into a conference room to help with a video call setup. The user is unable to get the laptop screen to mirror to the in-room television. The technician confirms that the appropriate HDMI cable is plugged into the user's computer and the TV has a blinking logo on the screen Which of the following is most likely causing the issue?
- A. The user's laptop does not support screen mirroring
- B. The wrong input is selected on the television.
- C. The television has a defective A/C adapter cable.
- D. The television does not support screen mirroring
- E. The user does not have Bluetooth enabled on the laptop.
Answer: B
Explanation:
When a laptop screen fails to mirror to a television despite being correctly connected via an HDMI cable, a common issue is that the television is set to the wrong input source. Modern televisions have multiple input options (e.g., HDMI 1, HDMI 2, AV, etc.), and selecting the correct input that corresponds to the port the HDMI cable is connected to is essential for displaying the laptop's screen. The blinking logo on the TV screen typically indicates that the TV is functioning but not receiving a signal from the selected input source.
Changing the TV's input to the correct HDMI port should resolve the issue and allow the laptop screen to mirror onto the TV.
