CompTIA A+ Practice Test (220-1102)

End-user acceptance is the phase in the change management process where the end-user tests the system after the change is completed and ensures that it doesn’t hinder everyday operations.

A hard token is a hardware security device that is used to prove a user's identity by generating a unique security code used during login procedures, confirming the user possesses the device. Soft tokens or mobile applications can generate codes but are software-based and distinguished from physical tokens. Static passwords or codes stored on a hard device or any irremovable media has NO dynamic generating capability hence not making them hard tokens, but rather just ineffective storage mechanisms for sensitive data (except where protected by additional security measures).

An Acceptable Use Policy (AUP) is the correct document to create and distribute in this scenario. An AUP outlines the rules and guidelines for using company computer systems and networks. It typically includes information on appropriate internet usage, email etiquette, data protection, and consequences for policy violations. This document helps protect the company's assets, maintain security, and ensure that all employees understand their responsibilities when using company resources.

While a network topology diagram is important for IT staff, it doesn't address user behavior. Standard operating procedures are more focused on specific tasks rather than overall usage policies. Incident reports are created after an event occurs, not as a preventive measure.

Ensuring the antivirus definitions are up to date is critical because new malware variants are constantly being created, and up-to-date definitions are required to identify and remove them. Running a scan without updated definitions might not catch the latest threats. Restoring to a known good backup does not prevent future infections and might reintroduce the same malware if the backup is compromised. Disabling the antivirus might be performed during troubleshooting but is not a preventive measure. Completely reinstalling the operating system would eliminate current malware but does not prevent future infections and is an extreme measure that should only be taken if all other options fail.

The windows command line utility, pathping combines the functions of the commands tracert and ping.

A rollback plan is a critical document in change management that outlines the exact steps needed to revert a system to its last known stable state. This plan is essential for quickly recovering from a failed change, thereby minimizing operational disruption and downtime. A network topology diagram illustrates the network's layout, an Acceptable Use Policy (AUP) sets rules for users, and an incident report is created to document an issue after it has occurred; none of these are used to revert a failed update.

Before running any script, especially one downloaded or received from external sources, it is important to review the script's code to verify its safety and it doesn't contain any harmful elements. This precaution avoids unintentional actions like altering system settings, affecting system performance, or introducing malware. Executing foreign scripts without inspection can pose significant risks to system integrity and data security.

The 3-2-1 backup rule is the most appropriate backup rotation scheme for this scenario. This rule states that you should keep at least three copies of your data, store two backup copies on different storage media, and keep one copy off-site for disaster recovery. This strategy provides robust protection against various data loss scenarios, including hardware failures, accidental deletions, and natural disasters. It combines the benefits of on-site backups for quick recovery with off-site storage for protection against site-wide disasters. The Grandfather-Father-Son (GFS) scheme, while useful for long-term retention, doesn't specifically address the on-site and off-site requirements mentioned in the question. Full, incremental, and differential backups are types of backups rather than rotation schemes, and don't address the storage location requirements.

On a disk using the Master Boot Record (MBR) scheme, a maximum of four primary partitions are allowed. To create more than four volumes, one of the four available partition slots must be used to create an extended partition. This extended partition then acts as a container within which multiple logical partitions (volumes) can be created. Since the technician has already used three primary partition slots and needs two more volumes, the next step must be to create an extended partition in the last available slot. After that, the two required logical partitions can be created inside the extended partition. Creating another primary partition would use the last slot, allowing for only one more volume in total. A logical partition cannot be created directly; it must reside within an extended partition. Converting to GPT is a different partitioning scheme entirely and not what the scenario requires.

The correct command-line tool for this scenario is pathping, this is because it combines features of both ping and tracert. It not only shows the path to the server but also measures latency and packet loss at each hop along the route. This information is crucial for diagnosing where the connectivity issues may lie.

While traceroute can identify the route packets take, it does not provide the packet loss data that pathping does. Similarly, ping checks connectivity but does not analyze the path or detailed metrics.

Root access or jailbreaking a device allows the installation of unauthorized applications, often leading to increased security risks and performance issues. This practice can result in unauthorized changes to the system settings, increased exposure to malicious software, and can also interfere with the device's normal operations, explaining the unexpected application behaviors and sluggish performance. The other options, while possible, are less directly related to the presence of unauthorized apps and the specific symptoms described.

Updating the 'Asset tags and IDs' information is crucial because each asset tag or ID is unique to the individual piece of hardware. By keeping these records up-to-date, the database reflects the most current status of all assets, allowing for effective tracking and management. Updating serial numbers, though important, doesn't directly reflect asset tracking for management and procurement processes. The technicians involved in upgrades and the location of ESD equipment are not as critical in asset management databases as the assets' unique identifiers.

The shutdown command-line tool can be used to shut down or restart a local or remote machine. The various switches provided with the command can be used to specify options like remote shutdown, the delay in shutdown, and the message to be displayed to the users. netstat is used to display networking statistics and does not have the capability to shut down a machine. gpupdate is used to manually update group policy settings on a particular machine. net use is utilized to connect, remove, and configure connections to shared resources, like mapped drives and network printers. poweroff is a similar command for Linux, not Windows. powershell is the name of a cross-platform command-line shell and scripting language created by Microsoft.

Investigate installed browser extensions for any that appear suspicious or unnecessary - This is correct. Malicious or unnecessary browser extensions are a common cause of frequent pop-ups and redirects. Identifying and removing suspicious extensions can directly address the root cause of the issue.

Clear the browser's cache and cookies to eliminate stored data - Clearing the cache and cookies can resolve some browsing issues, but it is unlikely to stop pop-ups and redirects caused by malicious extensions or malware.

Disable JavaScript in the browser settings to reduce pop-ups - Disabling JavaScript can reduce some pop-ups, but it may also break the functionality of many legitimate websites. This is not a practical or targeted solution for troubleshooting this issue.

Update the browser to the latest version to ensure security patches are applied - Updating the browser is good practice for overall security but is unlikely to resolve the specific issue of pop-ups and redirects caused by malicious extensions or adware.

To resolve the browser crashes and system performance issues, the technician should modify the script to prevent multiple instances of the backup process from running simultaneously. This action ensures that the script consumes only the necessary amount of system resources, avoiding the overutilization that leads to system crashes and performance degradation. Running the script at a time when workstations are least used and ensuring only one instance runs at a time prevents overconsumption of resources. Limiting browser functions, reinstalling the browsers, or instructing users to close their browsers do not address the underlying problem of multiple backup processes running concurrently.
