The technician can enter the proxy server address and port number, and specify which websites to bypass the proxy server for. The other tabs are not relevant for configuring the proxy server settings. References: CompTIA A+ Certification Exam Core 2 Objectives, page 9, section 1.7; CompTIA A+ Core 2 (220-1102) Certification Study Guide, page 140, section 1.7.

Installing new software on an organization’s system or device can have various implications, such as compatibility, security, performance, licensing, and compliance issues. Therefore, it is important to follow the best practices for software installation, such as doing research on the software, checking the system requirements, scanning the installation file for malware, and obtaining the proper license345. The technician should not install the software without formal approval from the management team, as this could violate the organization’s policies or regulations. The technician should also not install the software without investigating the software and its impact on the organization, as this could introduce potential risks or problems to the system or device. The technician should indicate to the developer that formal approval is needed, and then work with the IT team to evaluate the software and its suitability for the organization before installing it

The most likely causes of the user’s Windows computer performance degradation and freezing are insufficient RAM and excessive software running in the background. Therefore, the technician should do the following to resolve the issue:

Increase the RAM. RAM is the memory that the computer uses to store and run applications and processes. If the RAM is not enough to handle the workload, the computer will use the hard drive as a virtual memory, which is much slower and can cause performance issues. Increasing the RAM will allow the computer to run more applications and processes smoothly and avoid freezing. The technician should check the system requirements of the applications that the user needs to run, and install additional RAM modules that are compatible with the motherboard and the existing RAM. The technician should also make sure that the system is managing the page file size automatically, or adjust it manually to optimize the virtual memory usage12.

Uninstall unnecessary software. Software that the user does not need or use can take up valuable disk space and system resources, and can interfere with the performance of other applications. Some software may also run in the background or start automatically when the computer boots up, which can slow down the system and cause freezing. The technician should help the user to identify and uninstall unnecessary software from the control panel or the settings app, and disable unnecessary startup programs from the task manager or the system configuration tool. The technician should also check for and remove viruses and malware that may affect the system performance134.

A sandbox is an isolated environment that allows for the testing of critical systems without the risk of them being negatively impacted by changes. A sandbox can be used to simulate real-world scenarios, experiment with new features, debug errors, or evaluate the performance and security of a system. A sandbox can be created using virtualization, emulation, or containerization technologies. A sandbox prevents any changes made in the testing environment from affecting the production environment, which is the actual system that is used by the end users.
