The technician should check the Wi-Fi connection speed first to troubleshoot this issue. Slow web browsing speed on a mobile phone can be caused by a slow Wi-Fi connection. The technician should check the Wi-Fi connection speed to ensure that it is fast enough to support web browsing. If the Wi-Fi connection speed is slow, the technician should troubleshoot the Wi-Fi network to identify and resolve the issue.

To ensure device security on the network while adhering to industry best practices, the technician should:

Automate the patching process: This ensures that all devices receive the latest security updates in a timely manner without manual intervention, reducing the risk of vulnerabilities.

Monitor the firewall configuration: Important for network security but does not directly ensure all devices are patched.

Implement access control lists: Controls access to resources but does not ensure devices are patched.

Document all changes: Important for change management but does not directly impact the patching process.

When troubleshooting an application that is not performing well and occasionally shuts down with no error, the "Performance" tab in Task Manager is the most appropriate tool to use. This tab provides real-time data on CPU, memory, disk, and network usage, which can help identify resource bottlenecks or spikes that could be causing the application to malfunction. Monitoring these metrics while the application is running can offer insights into whether the issue is related to system resources.

A. Users tab shows which users are currently logged into the system and their resource usage but does not provide detailed performance metrics for troubleshooting application issues.

B. Services tab shows the status of background services but does not provide direct information about the application's performance.

D. Startup tab manages which applications start with Windows and their impact on startup time but is not useful for monitoring active application performance.

VNC (Virtual Network Computing) is a remote access tool that allows the technician to access and control various Windows, Linux, and macOS desktops on the company LAN using a graphical user interface. VNC does not require an external internet connection, as it works over a local network or a VPN. VNC uses a client-server model, where the server runs on the remote desktop and the client connects to it from another device. VNC can transmit the keyboard and mouse events from the client to the server, and the screen updates from the server to the client, enabling the technician to interact with the remote desktop as if it were local12.

VNC is a better option than the other choices because:

RMM (Remote Monitoring and Management) (B) is not a single software solution, but a category of software solutions that enable IT professionals to remotely monitor, manage, and troubleshoot multiple devices and networks. RMM software may include remote access tools, but also other features such as patch management, backup and recovery, security, reporting, and automation. RMM software may require an external internet connection, as it often relies on cloud-based services or web-based consoles34.

RDP (Remote Desktop Protocol) © is a remote access tool that allows the technician to access and control Windows desktops on the company LAN using a graphical user interface. However, RDP is not compatible with Linux or macOS desktops, unless they have third-party software installed that can emulate or translate the RDP protocol. RDP also has some security and performance issues, such as encryption vulnerabilities, bandwidth consumption, and latency problems56.

SSH (Secure Shell) (D) is a remote access tool that allows the technician to access and control various Windows, Linux, and macOS desktops on the company LAN using a command-line interface. SSH does not require an external internet connection, as it works over a local network or a VPN. SSH uses encryption and authentication to secure the communication between the client and the server. However, SSH does not provide a graphical user interface, which may limit the functionality and usability of the remote desktop7 .

Time Machine is a backup feature available in macOS that automatically makes hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for all previous months to an external drive or NAS. It allows users to recover the entire system or specific files from any point in time, ensuring access to multiple versions of files. This feature is particularly useful for reverting to earlier versions of a document or recovering a file that has been accidentally deleted or altered. The other options, such as Multiple Desktops, Remote Disc, and FileVault, do not provide versioning capabilities for file access.

The app file type is designed to run under macOS as an application file bundle. macOS uses application bundles to store executable files and related resources, such as libraries, image files, and localized content, in a single directory hierarchy. This approach simplifies application management and execution within the macOS environment​​.
