Comprehensive and Detailed Explanation From Exact Extract:

VPN clients often create virtual network adapters. If the software wasn't uninstalled properly or crashed during install, leftover (often hidden) virtual adapters can prevent reinstallation. The proper solution is to delete hidden network adapters using Device Manager (with ''Show hidden devices'' enabled).

A . OS updates won't fix a leftover driver or adapter issue.

B . Mapping an adapter to the software is not a standard or viable solution.

C . Firmware updates apply to physical adapters, not virtual VPN adapters.

The correct answer is C. In-place upgrades, because this migration method preserves existing user data, applications, and settings while upgrading the operating system to a newer version. Since a large percentage of users store documents locally, maintaining those files during the upgrade is a key requirement.

According to the Quentin Docter -- CompTIA A+ Complete Study Guide, an in-place upgrade replaces the operating system files while keeping user profiles, installed applications, and local data intact. This significantly reduces the risk of data loss and minimizes disruption to users.

The Travis Everett & Andrew Hutz -- CompTIA A+ All-in-One Exam Guide explains that clean installs erase the existing OS and require data backup and restoration, which is time-consuming and risky when users store files locally. Zero-touch deployments are automated but typically rely on standardized images and centralized data storage, which does not align with this scenario.

The Mike Meyers / Mark Soper Lab Manual reinforces that in-place upgrades are ideal when preserving user environments is a priority and when systems already meet the requirements for the newer OS.

Because the goal is to upgrade Windows while retaining locally stored documents, in-place upgrades are the most appropriate solution, making C the correct answer.

The correct answer is A. Perform a factory reset, because the symptoms strongly indicate a serious mobile malware infection, potentially including spyware or a trojan installed from an unofficial app store. Random pop-ups, excessive data usage, blocked access to banking apps, and inability to update the OS are classic indicators that malicious software has gained deep system-level access.

According to the Quentin Docter -- CompTIA A+ Complete Study Guide, mobile malware installed from unofficial sources can embed itself deeply into the operating system, sometimes gaining device administrator privileges. In such cases, standard remediation steps such as clearing cache or uninstalling apps may be ineffective.

The Travis Everett & Andrew Hutz -- All-in-One Exam Guide explains that when a mobile device shows signs of persistent compromise---especially when core OS functions and security-sensitive applications are affected---the recommended first step is to perform a factory reset. This completely wipes user-installed applications and restores the device to a known-good state.

The Mike Meyers / Mark Soper Lab Manual reinforces that changing passwords is important after the device is secured, not before. Contacting support or clearing cache does not remove deeply embedded malware.

Therefore, to immediately address the security threat and regain control of the device, a factory reset is the most appropriate first action, making A the correct answer.

Linux distributions are open-source and generally free of licensing fees, making them suitable for both desktop workstations and servers. Organizations can use the same Linux OS across all their systems without incurring per-seat or per-server costs, unlike proprietary systems such as Windows or macOS.

A very large or complex spreadsheet can consume excessive RAM and CPU cycles, causing the application to hang or become unresponsive. By checking the file's size and monitoring how much memory Excel (or the spreadsheet program) uses when opening it, the technician can confirm whether resource exhaustion is the culprit and take steps - like simplifying the file or adding RAM - to resolve the issue.

In a structured change-management process, the very first step is to propose (or formally request) the change via a Request for Change (RFC). This ensures stakeholders review the need, assess risks, and determine the priority before any approvals, scheduling, or implementation occur.
