BitLocker is a Windows security feature that provides encryption for entire volumes, addressing the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned devices1. BitLocker helps mitigate unauthorized data access by enhancing file and system protections, rendering data inaccessible when BitLocker-protected devices are decommissioned or recycled1. Network share, Group Policy, and Static IP are not features that can prevent unauthorized data access if a computer is lost or stolen.

Rebooting the smartphone is the first and simplest step to resolve the issue of frequent crashes and unresponsiveness. Rebooting clears the memory, closes the background apps, and refreshes the system. It can also fix minor glitches and bugs that may cause the calendar app or the smartphone to malfunction12. The other options are either too drastic or unnecessary. Reinstalling the application may not solve the problem if the issue is with the smartphone itself. Updating the smartphone’s OS may not be possible or helpful if the device is unresponsive or incompatible. Resetting the smartphone to factory settings will erase all the data and settings on the device, which should be the last resort.

Windows is widely used in industrial and business environments due to its major market presence, extensive support from the industry, and a broad selection of operating system options. It supports a wide variety of software, making it suitable for running complex systems like an inventory management system in a factory. Other options such as Chrome OS, Android, and iOS are either more consumer-oriented or designed for specific types of devices, making them less likely choices for an industrial application like inventory management.References: Professor Messer’s CompTIA 220-1102 A+ Course Notes​​.

Isolating the machine from the network is the best way to identify the source of the attack, because it prevents the malicious traffic from spreading to other devices or reaching the attacker. Isolating the machine can also help preserve the evidence of the attack, such as the malware files, the network connections, the registry entries, or the system logs. By isolating the machine, a technician can safely analyze the machine and determine the source of the attack, such as a phishing email, a compromised website, a removable media, or a network vulnerability.

An acceptable use policy (AUP) is a document that defines the rules and expectations for the users of a system, network, or service. It typically covers topics such as the purpose, scope, responsibilities, and restrictions of using the system, network, or service1. An AUP is a suitable place to publish the guidelines for the incorporation of generative AI solutions, as it can inform the users of the benefits, risks, and ethical implications of using such tools. It can also specify the conditions and limitations for using generative AI solutions, such as the types of data, content, and applications that are allowed or prohibited, the security and privacy requirements, the legal and regulatory compliance, and the accountability and reporting mechanisms23.

The SSID (Service Set Identifier) is the name of a wireless network that is broadcasted by the router or the Wi-Fi base station. The SSID helps nearby devices to identify and connect to the available networks. However, broadcasting the SSID also exposes the network to potential connection attempts from unauthorized or malicious users. Therefore, disabling the SSID can mitigate connection attempts by making the network invisible or hidden to the devices that are not already connected to it. To connect to a hidden network, the user would need to know the exact SSID and enter it manually.

The other options are not related to mitigating connection attempts to the corporate Wi-Fi. DHCP (Dynamic Host Configuration Protocol) is a protocol that assigns IP addresses to the devices on a network. Firewall is a software or hardware device that filters the incoming and outgoing network traffic based on predefined rules. SSD (Solid State Drive) is a type of storage device that uses flash memory to store data. Disabling any of these options would not prevent connection attempts to the Wi-Fi network, and may cause other problems or issues for the network functionality and performance.

Full backup is the best option to ensure that the restore process is as simple as possible. A full backup is a backup type that copies all the data from the source to the destination, regardless of whether the data has changed or not. A full backup provides the most complete and consistent backup of the data, and it allows the user to restore the data from a single backup set without relying on any previous or subsequent backups. Incremental, differential, and synthetic backups are not as simple as full backups for restoring data. An incremental backup is a backup type that copies only the data that has changed since the last backup, whether it was full or incremental. An incremental backup requires less time and space than a full backup, but it also requires multiple backup sets to restore the data completely. A differential backup is a backup type that copies only the data that has changed since the last full backup. A differential backup requires more time and space than an incremental backup, but it also requires fewer backup sets to restore the data than an incremental backup. A synthetic backup is a backup type that combines a full backup with one or more incremental or differential backups to create a consolidated backup set. A synthetic backup requires less time and bandwidth than a full backup, but it also requires more processing power and storage space than an incremental or differential backup. References:

The best way to deal with an angry customer who is yelling at a technician is to wait until the customer is done speaking and offer assistance. This shows respect, empathy, and professionalism, and allows the technician to understand the customer’s problem and find a solution. According to the CompTIA A+ Core 2 (220-1102) Certification Study Guide1, some of the steps to handle angry customers are:

Stay calm and do not take it personally.

Listen actively and acknowledge the customer’s feelings.

Apologize sincerely and offer to help.

Restate the customer’s issue and ask for clarification if needed.

Explain the possible causes and solutions for the problem.

Provide clear and realistic expectations for the resolution.

Follow up with the customer until the issue is resolved.

The other options are not appropriate ways to deal with angry customers, as they may worsen the situation or damage the customer relationship. Placing the customer on hold may make them feel ignored or dismissed. Disconnecting the call may make them feel disrespected or abandoned. Escalating the issue to a supervisor may make them feel frustrated or powerless, unless the technician cannot resolve the issue or the customer requests to speak to a supervisor.

The hostname command-line tool is used to display the name of the local machine. This information can be crucial for identifying the device within a network, especially when setting up remote access or sharing resources like folders and printers. Unlike other command-line tools that provide more detailed network diagnostics or configuration details, hostname straightforwardly offers the device's network identification, making it suitable for the scenario described.References: Official CompTIA A+ Core 1 and Core 2 Student Guide​​.

The most likely cause of the intermittent crashes is that the proprietary software is incompatible, outdated, or corrupted. Reinstalling and updating the software can fix these issues and ensure the software runs smoothly. Reimaging the computer or replacing the system RAM are too drastic and unnecessary steps. Decreasing the page file size can worsen the low memory problem and affect the performance of other applications.

A technician should handle personal communication while on site in a professional and respectful manner. According to the CompTIA A+ Core 2 (220-1102) exam objectives, one of the best practices for communication skills is to “avoid distractions and interruptions” when working with customers1. This means that the technician should not respond to calls and text messages that are not related to the work or the customer, unless there is an emergency situation that requires a response. Responding to personal communication while on site can be seen as rude, unprofessional, and disrespectful to the customer and their time. It can also affect the quality and efficiency of the technician’s work and cause errors or delays. Therefore, the technician should only respond to calls and text messages when an emergency situation requires a response, and inform the customer about the situation and apologize for the interruption.

The other options are not appropriate for handling personal communication while on site. Responding to calls and text messages while on site but not when working directly with personnel (A) is still distracting and unprofessional, as it can interfere with the technician’s focus and productivity. Responding to calls and text messages only from family (B) is not a valid criterion, as the technician may receive calls and text messages from other sources that are not related to the work or the customer. Responding to calls and text messages discreetly while on site (D) is not a good practice, as it can still be noticed by the customer or other personnel and create a negative impression.

A VPN (Virtual Private Network) is a service that allows remote employees to access the company’s network resources securely over the internet as if they were on premises. A VPN encrypts the data traffic between the employee’s device and the VPN server, and assigns the employee a virtual IP address that belongs to the company’s network. This way, the employee can access the local servers, files, printers, and other resources without exposing them to the public internet. A VPN also protects the employee’s privacy and identity by masking their real IP address and location.

MFA stands for multi-factor authentication, which is an electronic authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN1. MFA provides security enhancement by making it harder for attackers to compromise the user’s identity or credentials, as they would need to obtain more than just the username and password. MFA can also prevent unauthorized access to sensitive data or resources, as well as reduce the risk of identity theft or fraud2. 

The scope of the change is one of the elements that should be documented to ensure that the change management plan is followed. The scope of the change defines the boundaries and limitations of the change, such as what is included and excluded, what are the deliverables and outcomes, what are the assumptions and constraints, and what are the dependencies and risks. The scope of the change helps to clarify the expectations and objectives of the change, as well as to prevent scope creep or deviation from the original plan. The scope of the change also helps to measure the progress and success of the change, as well as to communicate the change to the stakeholders and the team

The Network and Sharing Center is a Control Panel utility that allows users to view and modify network settings, such as IP address, subnet mask, default gateway, DNS servers, and network profiles. To change the IP and gateway settings of a Windows workstation, the technician can follow these steps:

Open the Network and Sharing Center by clicking on the network icon in the system tray or by searching for it in the Start menu.

Click on Change adapter settings on the left sidebar.

Right-click on the network adapter that is connected to the network and select Properties.

Double-click on Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) depending on the network protocol used.

Select Use the following IP address and enter the desired IP address, subnet mask, and default gateway for the workstation. Alternatively, select Obtain an IP address automatically if the network uses DHCP to assign IP addresses dynamically.

Click OK to save the changes and close the dialog boxes.
