CompTIA A+ Practice Test (220-1102)

Asking "What specific issues are you experiencing with the application?" is an open-ended question that invites the user to describe symptoms in their own words, providing richer detail for troubleshooting. The other options are closed-ended (yes/no) or lead the user toward a particular issue, which can limit the information gathered.

Unwanted desktop alerts are a classic sign of adware or other malware installed on the system. Performing a full antivirus or anti-malware scan is the most effective first step because it identifies and removes malicious programs that generate the notifications. Simply disabling applications or turning off notifications may hide the symptom but leaves the malware in place. Rebooting or installing Windows updates is good practice but rarely removes adware that is already resident on the computer.

A privacy screen is a thin piece of plastic that goes over a device's screen. The privacy screen is transparent for users sitting directly in front of the devices screen, but for anyone looking at the screen from an angle the screen is blocked, blurred or heavily darkened. This protects against confidential data on a screen from being easily visible to others in the area.

Degaussing is the process of erasing data from magnetic storage devices by using a powerful magnetic field. This process makes the data on the storage medium unrecoverable, meeting high security standards. Standard formatting and erasing do not completely eliminate data, and low-level formatting (while effective) is more complex and less practical compared to degaussing.

Scanning and removing malware in safe mode is the best approach because it starts Windows in a minimal state, loading only essential drivers and services. This prevents most malware from running, making it easier for the anti-malware software to detect and remove the threat. Scanning in normal mode may allow the malware to continue running and interfering with the removal process. While a preinstallation environment can be useful for severe infections, it's not typically necessary for most malware removal scenarios. Reformatting the drive should be considered a last resort, as it will erase all data on the drive.

Disabling the SSID broadcast may make the network less obvious to the casual user, but it does not make it completely undetectable. Wireless network analysis tools can still find networks with a disabled SSID broadcast and detect the network. Therefore, while slightly more hidden, it does not provide impenetrable security against detecting the network.

The first action should disable the user account so that the issue can be further investigated safely. You should not change or delete anything else, like deleting the account or disabling the servers yet as the login attempts are not succeeding. Only disabling the user account's ability to login would not prevent any existing authenticated sessions from accessing resources and is a less safe option given the possibility of a security breach in progress.

The correct lifting technique involves bending at the hips and knees to squat down, keeping the back straight, and using the powerful leg muscles to lift the load. Bending at the waist uses weaker back muscles, which significantly increases the risk of injury. Twisting the body while lifting or carrying a heavy object also puts dangerous strain on the spine. Objects should be held close to the body to maintain control and minimize strain on the back.

ping verifies IP-level connectivity to another TCP/IP computer by sending Internet Control Message Protocol (ICMP) echo Request messages. The receipt of the corresponding echo Reply messages is displayed, along with round-trip times. ping is the primary TCP/IP command used to troubleshoot connectivity, reachability, and name resolution. Used without parameters, this command displays Help content.

The correct answer is to recycle the toner cartridges through the manufacturer's recycling program. Many printer manufacturers offer free recycling programs for their toner cartridges. This is the most environmentally responsible option, as it allows for the proper handling of potentially harmful materials and the reuse of recyclable components.

Throwing toner cartridges in the regular trash is incorrect and potentially harmful to the environment, as toner contains materials that can be toxic if not disposed of properly. Burning the cartridges is extremely dangerous and illegal in most jurisdictions due to the release of toxic fumes. Storing them indefinitely is not a solution and wastes valuable office space while potentially creating a safety hazard.

Configuring the workstation to activate the screensaver and lock the screen automatically after a short duration of inactivity ensures that the workstation is secured if a user steps away. Manual locking and password policies are important but rely on the user's proactive actions or apply broadly.

A clean installation will completely delete existing data and partitions on the chosen disk. It can be used to re-install the previous OS with a clean state, upgrade an OS or switch operating system types (e.g. from Windows to Linux). If data needs to be kept it should be backed up to a different drive or cloud provider first.

A rollback plan is a documented plan that states what steps will be taken in the event an approved change fails. This plan usually includes a way to revert back to the state before the change.

An automated voice call that delivers a one-time verification code to a preregistered telephone number demonstrates possession of that phone line, so it meets the "something you have" factor in MFA. A strong password and a security question are both "something you know" factors, while a CAPTCHA only proves that the user is likely human and is not an authentication factor at all.

.sh scripts are used to automate tasks specifically on Unix-like operating systems, including Linux. These scripts contain commands that are executed by the shell interpreter. Other script types such as .bat, .ps1, and .vbs are more commonly associated with Windows operating systems.
