NEW QUESTION 3
A PC is taking a long time to boot. Which of the following operations would be best to do to resolve the issue at a minimal expense? (Select two).

• A. Installing additional RAM
• B. Removing the applications from startup
• C. Installing a faster SSD
• D. Running the Disk Cleanup utility
• E. Defragmenting the hard drive
• F. Ending the processes in the Task Manager

Answer: BD

Explanation:
Removing the applications from startup can improve the boot time of a PC by reducing the number of programs that load automatically when the PC starts. Some applications may add themselves to the startup list without the user’s knowledge orconsent, which can slow down the PC’s performance. Running the Disk Cleanup utility can also improve the boot time of a PC by deleting unnecessary or temporary files that take up disk space and affect the PC’s speed. Disk Cleanup can also remove old system files that may cause conflicts or errors during booting. Installing additional RAM, installing a faster SSD, defragmenting the hard drive, and ending the processes in the Task Manager are not operations that would be best to do to resolve the issue of slow boot time at a minimal expense, as they may require purchasing new hardware or software, or may have negative impacts on other aspects of the PC’s performance.

NEW QUESTION 4
A technician connects an additional monitor to a PC using a USB port. The original HDMI monitor is mounted to the left of the new monitor. When moving the mouse to the right from the original monitor to the new monitor, the mouse stops at the end of the screen on the original monitor. Which
of the following will allow the mouse to correctly move to the new monitor?

• A. Rearranging the monitor's position in display settings
• B. Swapping the cables for the monitors
• C. Using the Ctrl+AIt+> to correct the display orientation
• D. Updating the display drivers for the video card

Answer: B

Explanation:
The correct answer is B. Swapping the cables for the monitors. When the second monitor is connected with the HDMI port, it is necessary to swap the cables for the monitors so that the mouse can move from the original monitor to the new monitor. This is because the HDMI port is designed to only support one monitor, and the mouse will not be able to move from one to the other without the cables being swapped.
According to CompTIA A+ Core 2 documents, "When connecting multiple displays to a system, the cables used to connect the displays must be swapped between the displays. For example, if a monitor is connected to a system using a VGA cable, the VGA cable must be moved to the next display to allow the mouse to move between the two displays."

In Windows 10, there are privacy settings that control access to certain devices, such as microphones, cameras, and other input devices. If the microphone is not enabled under these privacy settings, the VoIP application may not have access to it, causing a lack of outgoing audio.
The technician can go to the Windows 10 Settings menu, select the Privacy submenu, and under App permissions, select Microphone. The technician should then turn on the toggle switch for the VoIP application to allow it to access the microphone.
Removing the microphone from the USB hub and plugging it directly into a USB port on the PC may or may not solve the issue, as the issue could be related to the privacy settings. Deleting the microphone from Device Manager and scanning for new hardware may also not solve the issue, as the issue could be related to the privacy settings. Replacing the USB microphone with one that uses a traditional 3.5mm plug is not recommended, as it would require purchasing a new microphone and may not solve the issue.

NEW QUESTION 11
A hotel's Wi-Fi was used to steal information on a corporate laptop. A technician notes the following security log:
SRC: 192.168.1.1/secrets.zip Protocol SMB >> DST: 192.168.1.50/capture The technician analyses the following Windows firewall information:

Which of the following protocols most likely allowed the data theft to occur?

• A. 1
• B. 53
• C. 110
• D. 445

Answer: D

Explanation:
The protocol that most likely allowed the data theft to occur is SMB over TCP port 445. SMB is a network file sharing protocol that enables access to files, printers, and other resources on a network. Port 445 is used by SMB to communicate directly over TCP without the need for NetBIOS, which is an older and less secure protocol. The security log shows that the source IP address 192.168.1.1 sent a file named secrets.zip using SMB protocol to the destination IP address 192.168.1.50, which captured the file. The Windows firewall information shows that port 445 is enabled for inbound and outbound traffic, which means that it is not blocked by the firewall. Therefore, port 445 is the most likely port that was exploited by the attacker to steal the data from the corporate laptop.

NEW QUESTION 14
A technician is trying to connect to a user's laptop in order to securely install updates. Given the following information about the laptop:

Which of the following should the technician do to connect via RDP?

• A. Confirm the user can ping the default gateway.
• B. Change the IP address on the user's laptop.
• C. Change the subnet mask on the user's laptop.
• D. Open port 3389 on the Windows firewall.

Answer: D

Explanation:
In order to connect to a user’s laptop via RDP, the technician should open port 3389 on the Windows firewall. This is because RDP uses port 3389 for communication12. The other options are not necessary or relevant for establishing an RDP connection.
✑ Confirming the user can ping the default gateway is not required for RDP, as it
only tests the network connectivity between the user’s laptop and the router. RDP works over the internet, so the technician should be able to ping the user’s laptop directly using its IP address3.
✑ Changing the IP address on the user’s laptop is not needed for RDP, as long as
the IP address is valid and not conflicting with another device on the network. The user’s laptop has a valid IP address of 192.168.0.45, which belongs to the same subnet as the gateway (192.168.0.1) and the subnet mask (255.255.255.0)4.
✑ Changing the subnet mask on the user’s laptop is not required for RDP, as long as
the subnet mask matches the network configuration. The user’s laptop has a correct subnet mask of 255.255.255.0, which defines a network with 254 possible hosts4.

NEW QUESTION 19
A technician installed Windows 10 on a workstation. The workstation only has 3.5GB of usable RAM, even though the technician installed 8GB. Which of the following is the MOST likely reason this system is not utilizing all the
available RAM?

• A. The system is missing updates.
• B. The systems utilizing a 32-bit OS.
• C. The system's memory is failing.
• D. The system requires BIOS updates.

Answer: B

Explanation:
The most likely reason that the system is not utilizing all the available RAM is that it is running a 32-bit OS. A 32-bit OS can only address up to 4GB of RAM, and some of that is reserved for hardware and system use1. Therefore, even if the technician installed 8GB of RAM, the system can only use around 3.5GB of usable RAM. To use the full 8GB of RAM, the technician would need to install a 64-bit OS, which can address much more memory2. The system missing updates, the system’s memory failing, or the system requiring BIOS updates are not likely to cause this issue.
