NEW QUESTION # 619
A client's device was recently used by multiple other users. The client reports their device is now running slower than usual. Which of the following steps should a technician take first? (Select two.)

Answer: B,C

Explanation:
Comprehensive and Detailed In-Depth Explanation:
The two best first steps are:
* Perform a virus scan - Multiple users on a device increase the risk of malware, which can cause performance issues.
* Check the startup programs - Unnecessary programs running at startup can slow down the system.
* C. Back up the data - Important but not the first step for performance troubleshooting.
* D. Disable the guest account - May prevent future unauthorized use but does not immediately fix the current issue.
* E. Update the firmware - Firmware updates improve hardware stability but are unlikely to fix a sudden performance drop.
* F. Reinstall the operating system - A last resort, as it erases data and takes significant time.

NEW QUESTION # 620
A technician is doing a bare-metal installation of the Windows 10 operating system. Which of the following prerequisites must be in place before the technician can start the installation process?

Answer: C

Explanation:
Before starting a bare-metal installation of Windows 10, ensuring that there is sufficient storage space on the system's hard drive or SSD is crucial. This is because the installation files need enough room to be copied and for the operating system to be installed and function properly. Without adequate storage, the installation process can fail or the operating system might not perform optimally. Other prerequisites like internet connection, product key, and specific firmware types might be necessary at different stages of installation or activation, but the fundamental requirement is enough storage space to accommodate the new OS.


NEW QUESTION # 621
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?

Answer: B

Explanation:
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 # 622
A user's new laptop, which was advertised as gaming-ready, is performing slowly when the user is playing a modern game. However, when the user is playing a less resource-demanding game, the user does not see any lag. Which of the following should a technician do to resolve the issue?

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Many modern laptops have both an integrated GPU (built into the CPU) and a dedicated GPU (such as NVIDIA or AMD). The system may default to the integrated GPU to save power, which results in poor gaming performance. The technician should manually set the game to use the dedicated graphics card to resolve the issue.
* A. Overclock the RAM - Incorrect. While overclocking RAM can improve performance slightly, it does not resolve GPU-related gaming lag.
* B. Enable NIC teaming - Incorrect. NIC teaming improves network bandwidth and has no effect on gaming graphics.
* D. Activate CPU hyperthreading - Incorrect. Hyperthreading improves multitasking but does not directly impact gaming graphics performance.

NEW QUESTION # 623
Which of the following is a consequence of end-of-lite operating systems?

Answer: D

Explanation:
Explanation
End-of-life operating systems are those which have reached the end of their life cycle and are no longer supported by the software developer. This means that the operating system will no longer receive updates, security patches, or other new features. This can leave users vulnerable to security threats, as the system will no longer be protected against the latest threats. Additionally, this can make it difficult to migrate data to a newer operating system, as the old system is no longer supported.
