CompTIA A+ Practice Test (220-1102)

The Administrator account has full control over the system, allowing for complete access to all files, settings, and system management tools. Standard user accounts are limited and cannot make changes affecting other users or the security of the system. Guest accounts are even more restricted and are typically used for temporary access with limited privileges.

The correct answer is the Enterprise edition, which provides the most comprehensive set of features for business environments, including domain access and BitLocker for data protection and Device Guard.

The Pro edition also allows binding to a domain and includes BitLocker, making it a suitable option for smaller businesses or professional use but it does not support Device Guard. The Home edition lacks these capabilities, while the Pro for Workstations is designed for high-performance tasks but does not offer any additional enterprise features beyond what Pro provides.

An organizational unit (OU) is the correct choice because OUs are containers within a domain that can hold users, groups, and computers. They are the smallest scope to which Group Policy Objects (GPOs) can be linked and are used to delegate administrative authority. A security group is used to assign permissions to resources, not to link GPOs. A home folder is a user-specific storage location. A domain represents a much broader security boundary and is not the appropriate level for delegating departmental control.

A primary tactic of many malware variants is to disable system security features, including the firewall and anti-malware software, to prevent detection and removal. While a conflicting third-party security application could legitimately disable the Windows firewall, or a failed OS update could cause system instability, unsolicited and repeated notifications of this nature are a classic and high-priority symptom of a malware infection. A corrupted user profile is less likely to cause this specific behavior.

The most logical next step is to verify that the cellular network setting is enabled on the device. Even with an active data plan, the phone cannot connect to the internet if the mobile data option is turned off. Toggling Airplane mode and restarting the phone are also valid troubleshooting steps, but checking the primary setting first is a more direct and faster approach. Checking for a service outage is also a valid step, but it's more efficient to rule out device-specific settings before investigating external, area-wide problems.

Disabling the Service Set Identifier (SSID) broadcast is a security measure that makes the network less visible to devices trying to discover available wireless networks. It does not provide strong security but can add a layer of obscurity.

Before performing an in-place system upgrade, it is essential to back up all important files and user preferences. This is a precautionary step to prevent data loss in case of complications during the upgrade process. An upgrade could fail or cause unexpected issues, leading to the possibility of data corruption or loss. Having a backup allows users to restore their information if the upgrade does not go as planned.

The Users tab in Task Manager will show you the logged in users. The "who" command is for Linux, not Windows. MSINFO32 provides system information, Local Users and Groups shows user accounts on the system - not ones in use.

The best practice for disposing of used printer toner cartridges is to participate in a recycling program offered by the manufacturer or a certified recycling facility. This ensures that the materials are handled and processed properly, reducing environmental impact. Simply discarding them or giving them away might not guarantee proper handling.

The correct answer is that the Windows Update service is not running. The Windows Update service is a background process responsible for downloading and installing updates. If this service is stopped or disabled, updates will fail to install, even if the system has internet access and sufficient disk space. Restarting the laptop will not resolve the issue if the service is set to 'Disabled'. Lack of internet connectivity and insufficient disk space were ruled out in the scenario. While administrative privileges can be a factor in some software installations, standard users are typically able to initiate and install Windows updates, making a service failure the more probable cause in this situation.

64-bit Windows is capable of utilizing in excess of 4 GB of RAM. While most modern processors can utilize 32-bit or 64-bit Windows, that has not always been the case.

A request form is used to formally record a desired change, providing structured information for analysis and approval purposes. It ensures that changes are not made spontaneously and without oversight, which could lead to system disruptions or other issues. Instead, the process requires proper planning and documentation which is facilitated by a request form.

Microsoft Remote Assistance allows for the sharing and controlling of a Windows computer through a remote connection. During the connection, the user of the connected computer can actively see what is happening on the screen which is best suited for end-user support scenarios. RDP is a similar option, but would not allow both the local user and remote user to view the screen at the same time. Using RDP you could solve the user's issue remotely, but not able to show them how you did it so they can do it on their own which is a requirement of the question.

The option to check available storage on the device is the most effective step because insufficient storage is a common reason for failed updates. If the device does not have enough space to accommodate the update files, the installation will fail.

Other choices might address the issue, but are not as directly related to the immediate need to resolve the update failure. For example, restarting the device can help, but if there is insufficient storage, the update will still fail. Similarly, verifying network connectivity is relevant, but storage issues are often the more common cause.

The correct answer is to document which devices have Developer mode enabled and gather information on any unusual apps or modifications. This step is crucial as it helps in creating a record of the situation and determines if further actions, such as disabling Developer mode or performing security checks, are necessary. Checking for system updates, although important, doesn't immediately address the risks posed by having Developer mode enabled. Running a security audit is a broader action which might follow documentation but is not the first step. Optimizing battery settings is unrelated to the security risk posed by Developer mode.
