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.

An MSDS providessafety and emergency procedures, such as what to do if a battery leaks or catches fire. It is not a technical or setup guide.
FromTravis Everett - CompTIA A+ All-in-One Exam Guide:
"An MSDS contains safety information, including handling, storage, and emergency procedures related to potentially hazardous components like UPS batteries."

The correct answer is D. Hide extensions, because Windows File Explorer hides known file extensions by default, which can cause confusion when renaming files. When extensions are hidden, a user may unknowingly change only the visible filename and not the actual file extension.
The Quentin Docter - CompTIA A+ Complete Study Guide explains that Windows uses file extensions to determine file type associations. If file extensions are hidden, renaming a file from Document.txt to Document.
xml may actually result in Document.xml.txt, even though only Document.xml is displayed.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide states that to properly change a file's extension, users must enable "File name extensions" in File Explorer. This allows the user to see and modify the true extension, ensuring the operating system recognizes the correct file type.
The Mike Meyers / Mark Soper Lab Manual reinforces that options such as indexing, personalization, or formatting do not affect how Windows interprets file types. Only visibility of file extensions allows accurate renaming.
Therefore, disabling the "Hide extensions for known file types" setting is required to correctly change the file type, making D the correct answer.

Standard Operating Procedures (SOPs) define the mandatory steps and expectations technicians must follow during support calls. This includes documentation standards such as logging user info, asset details, and issue descriptions in the ticketing system. Implementing SOPs ensures consistency and accountability.
A). SLAs define response/resolution times but not documentation practices.
B). Call categories organize types of issues but don ' t guide technician actions.
D). Knowledge base articles provide solutions to known problems but don ' t ensure proper ticket documentation.

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."
