If internal resources (such as intranet or internal apps) can't be accessed but external sites work, this often points to aDNS issue, where the system isn't resolving internal domain names correctly.

FromAll-in-One Exam Guide:

“When internet access is functional but internal sites fail to load, the issue usually lies with DNS resolution. Internal resources often require internal DNS servers, which may not be configured correctly.”

Remote wipeis a mobile device management (MDM) feature that allows administrators to erase data remotely if a device is lost or stolen, preventing unauthorized access to corporate or personal information.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Remote wipe features enable a device to be cleared of all sensitive data if it is lost or stolen. This is one of the most effective ways to prevent unauthorized access to corporate resources.”

If the system fails to boot after removing the USB installation media, it often means the BIOS is not pointing to the correct boot device. This typically involves an issue with the BIOS settings—such as UEFI being disabled when the OS was installed in UEFI mode.

FromAll-in-One Exam Guideby Travis Everett:

“One of the most common post-installation issues is failing to configure the boot mode correctly in BIOS. If an OS is installed in UEFI mode, the UEFI boot must be enabled, otherwise the system won’t detect the bootloader.”

Apps like GPS or roaming services often drain battery during travel.Checking app utilizationhelps identify battery drain sources.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“Monitoring app activity can reveal high-power usage apps running in the background, especially when mobile data or GPS is active.”

Comprehensive and Detailed Explanation From Exact Extract:

Multifactor authentication (MFA) is considered one of the most effective security measures for cloud environments. It requires users to verify their identity using two or more factors (e.g., password + phone app code), making it significantly harder for external attackers to gain access, even if the primary password is compromised.

B. Encryption is important for data protection but doesn’t prevent unauthorized logins.

C. Backups protect against data loss but don’t stop breaches.

D. Strong passwords are helpful but can still be phished or cracked — MFA adds a critical extra layer.

An in-place upgrade is the fastest and most efficient way to upgrade from Windows 10 to Windows 11 while keeping all user data, applications, and settings intact. This method is often used when the hardware meets Windows 11 requirements and no system reconfiguration is necessary.

A. gpupdate is used to refresh Group Policy settings — unrelated to OS upgrades.

B. Image deployment typically replaces the current OS and may not retain user data unless specifically customized.

C. A clean install requires formatting the drive and starting fresh, which removes all data.

Comprehensive and Detailed Explanation From Exact Extract:

An Acceptable Use Policy (AUP) outlines the rules and guidelines for employees or users regarding the appropriate use of company systems, resources, and internet access. It defines permitted and prohibited activities, helping to mitigate security risks and establish clear behavioral expectations.

B. MNDA (Mutual Non-Disclosure Agreement) deals with confidentiality, not usage guidelines.

C. DRM (Digital Rights Management) controls access to copyrighted content.

D. EULA (End User License Agreement) pertains to software licensing, not internal policies.

Comprehensive and Detailed Explanation From Exact Extract:

To prevent external access, the technician should avoid exposing the surveillance system’s port to the public internet. Port mapping (also known as port forwarding) is the method used to control which internal devices and ports are accessible from the outside. By not configuring port forwarding for the device, external login attempts are effectively blocked.

B. Subnetting organizes IP addresses but doesn't directly restrict access.

C. A static IP ensures consistent addressing but does not secure access.

D. Content filtering is used to restrict web content, not to block access to a web interface.
