Show answer and explanation
Correct answer: A
Explanation
This question tests knowledge of Windows OS components and where to manage optional built-in features. In real support scenarios, business applications may depend on specific Windows components such as .NET Framework 3.5 or 4.x features. A technician should know that these are enabled through the Windows Features interface rather than hardware, startup, scheduling, or firewall tools. Microsoft documents optional feature management through the Windows Features dialog and DISM/PowerShell for advanced administration. For A+ Core 2, candidates should be familiar with common administrative utilities and understand the purpose of each OS component so they can choose the correct troubleshooting path efficiently.
- A. Correct.
Correct. In Windows, optional OS components such as versions of the .NET Framework, Hyper-V, SMB features, and other built-in Windows features are managed through Programs and Features > Turn Windows features on or off (or the equivalent Optional Features interface in newer builds). This is the appropriate place to enable a required Windows feature for application compatibility.
- B. Incorrect.
Incorrect. Device Manager is used to manage hardware devices and drivers, such as network adapters, display adapters, and storage controllers. It does not install or enable optional Windows software components like the .NET Framework.
- C. Incorrect.
Incorrect. System Configuration (msconfig) is primarily used for startup selection, boot options, and enabling or disabling startup services for troubleshooting. It is not the standard tool for adding Windows features such as .NET Framework components.
- D. Incorrect.
Incorrect. Task Scheduler is used to create and manage automated tasks that run on triggers or schedules. It does not manage installation of Windows optional components.
- E. Incorrect.
Incorrect. Windows Defender Firewall with Advanced Security is used to configure inbound and outbound firewall rules and connection security rules. Although application launch issues can sometimes be caused by firewall settings, this tool does not enable missing OS features like .NET Framework.
