Comprehensive and Detailed Explanation From Exact Extract:

NET Framework versions are often required for applications to run. If an older app requires .NET Framework 3.5, it must be explicitly installed as it is not included by default in newer versions of Windows. The best method to do this safely is through the built-in "Turn Windows features on or off" utility, which downloads and installs it via official Microsoft services.

B. Using third-party repositories is unsafe and not recommended.

C. Installing .NET 4 does not include 3.5; versions are not fully backward compatible.

D. The issue is technical, not a security incident for the SOC team.

Device encryptionensures that even if someone bypasses biometrics or has physical access to the phone, they cannot read the stored data without the encryption key.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Encryption is the most effective way to protect data at rest. Even if the device is lost or stolen, encryption ensures the data remains inaccessible without the correct key or passcode.”

Comprehensive and Detailed Explanation From Exact Extract:

Credential managers or password vaults (e.g., Windows Credential Manager, KeePass, or LastPass) store passwords securely. The integrity of such tools heavily depends on the strength of the master password protecting the vault. If compromised, all saved credentials could be exposed. Therefore, setting a secure master password is crucial.

A. Login time restrictions are general user account settings, not specific to credential managers.

C. TPM is used more commonly for full disk encryption, not specifically required for password managers.

D. The lock screen protects general access but does not protect stored credentials alone.

Comprehensive and Detailed Explanation From Exact Extract:

An evil twin is a rogue wireless access point set up to mimic a legitimate Wi-Fi network. Unsuspecting users may connect to it, giving attackers the opportunity to intercept traffic, steal credentials, or install malware. The evil twin often uses the same SSID as the real network to fool users.

A. Stalkerware is spyware installed to track user activity, typically on personal devices.

C. Tailgating is a physical security breach involving unauthorized entry behind someone with access.

D. Shoulder surfing involves observing a person entering confidential data, such as PINs or passwords.

Comprehensive and Detailed Explanation From Exact Extract:

For persistent printing issues due to spooler service, ensure theprint spooler is started and set to Automatic. This maintains print capability across reboots.

FromMike Meyers' Lab Manual:

“If users lose printing capabilities on reboot, the print spooler service must be configured to start automatically and be confirmed as running.”

Comprehensive and Detailed Explanation From Exact Extract:

3G networks generally do not provide the bandwidth required for seamless HD video streaming. With only two signal bars and a 3G connection, the mobile device likely cannot maintain the necessary data throughput, resulting in timeouts or buffering failures. This is a classic symptom of insufficient network speed or signal strength.

A. Lack of Wi-Fi may contribute, but the root cause is the low mobile bandwidth, not the Wi-Fi state.

B. A website subscription lapse would return an account error, not a timeout.

D. Full device storage can affect downloads but not streaming from the internet.

Comprehensive and Detailed Explanation From Exact Extract:

exFATis the only listed file system that supports both read and write access across Windows, macOS, and Linux (with appropriate drivers). It’s optimized for flash storage and external drives.

FromAll-in-One Exam Guide:

“exFAT is a lightweight file system with cross-platform read/write support, ideal for use on removable drives when compatibility is essential.”

Comprehensive and Detailed Explanation From Exact Extract:

RADIUS (Remote Authentication Dial-In User Service)provides centralized Authentication, Authorization, and Accounting (AAA) for users who connect and use a network service.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“RADIUS is a widely used protocol for implementing AAA in network environments, allowing centralized control over user access and accounting.”

Comprehensive and Detailed Explanation From Exact Extract:

Single sign-on (SSO)allows users to authenticate once and gain access to multiple systems without re-entering credentials, which significantly enhances user convenience while maintaining security.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Single sign-on streamlines authentication by allowing users to log in once and access all authorized resources, reducing credential fatigue and improving security.”

Comprehensive and Detailed Explanation From Exact Extract:

The ext4 (Fourth Extended Filesystem) is the most widely used default filesystem in modern Linux distributions. It is designed for high performance, scalability, and reliability, and is supported by all mainstream Linux kernels.

A. exFAT is used for cross-platform external drives, not native Linux systems.

B. APFS is Apple's proprietary filesystem for macOS and iOS.

D. NTFS is the default filesystem for Windows, not Linux.
