The best option for the technician to demonstrate proper communication techniques and professionalism is to contact the customer if the technician is arriving late. This shows respect for the customer’s time and expectations, and allows the customer to adjust their schedule accordingly. It also helps to maintain a positive relationship and trust between the technician and the customer. The technician should apologize for the delay and provide a realistic estimate of their arrival time. The technician should also thank the customer for their patience and understanding.

The other options are not appropriate or professional. Do not notify the customer if arriving before the customer is not a good practice, as it may cause confusion or frustration for the customer. The customer may have made other plans or arrangements based on the technician’s original schedule, and may not be available or prepared for the service. Dismiss the customer and proceed with the after-hours work is rude and disrespectful, as it ignores the customer’s needs and preferences. The customer may have questions or concerns about the service, or may want to supervise or verify the work. The technician should always communicate with the customer before, during, and after the service. Disclose the experience via social media is unethical and unprofessional, as it may violate the customer’s privacy and the company’s policies. The technician should not share any confidential or sensitive information about the customer or the service on social media, or make any negative or inappropriate comments about the customer or the situation.

EOL (end-of-life) is a term that indicates a vendor no longer supports a product. It means that the product will no longer be sold, updated or patched by the vendor, and that the users should migrate to a newer version or alternative product. AUP (acceptable use policy), EULA (end-user license agreement) and UAC (user account control) are not terms that indicate a vendor no longer supports a product.

A PIN code is a numeric password that protects a mobile device against unwanted access when it is left unattended. It requires the user to enter the correct code before unlocking the device. OS updates, antivirus software and BYOD policy are other security measures for mobile devices, but they do not prevent unauthorized access when the device is left unattended.

Preserving chain of custody is a concept that refers to the documentation and tracking of who handled, accessed, modified, or transferred a piece of evidence, when, where, why, and how. Preserving chain of custody can help establish the authenticity, integrity, and reliability of the evidence, as well as prevent tampering, alteration, or loss of the evidence. An administrator who documented the movement of the evidence demonstrated the concept of preserving chain of custody. Implementing data protection policies, informing law enforcement, and creating a summary of the incident are not concepts that describe the action of documenting the movement of the evidence.

ACL (access control list) is a security control that describes what permissions a user or group has on a shared network folder using NTFS (New Technology File System) security settings. It can be used to grant or deny read, write, modify, delete or execute access to files and folders. SMS (short message service), MFA (multifactor authentication), MDM (mobile device management) are not security controls that apply to shared network folders.

Shredding is a data destruction method that physically destroys the hard drive by cutting it into small pieces using a machine. Shredding ensures that data is completely removed from the hard drive and cannot be recovered by any means. Shredding is suitable for hard drives that contain PII (personally identifiable information), which is any information that can be used to identify, contact, or locate an individual. Degaussing, low-level formatting, and recycling are not data destruction methods that can guarantee complete data removal from a hard drive.

RDP stands for Remote Desktop Protocol and it is a protocol that allows a user to remotely access and control another computer over a network. A technician can use RDP to assist a user who is in a different building but on the same network by connecting to the user’s computer and viewing their screen, keyboard, and mouse. AAA, SSH, and VPN are not protocols that can be used to assist a user with a program feature.

DNS (domain name system) is a protocol that translates domain names to IP addresses. If the computer has an incorrect DNS address assigned, it will not be able to resolve the domain names of web-based applications and access them. A firewall, a VLAN (virtual local area network) and a browser cache are not the most likely reasons for the issue, since the computer can ping known IP addresses on the internet and receive a response.

yum (Yellowdog Updater Modified) is a package management utility for PCs that are running the Linux operating system. It can be used to install, update and remove software packages from repositories. chmod (change mode) is a command that changes the permissions of files and directories in Linux. man (manual) is a command that displays the documentation of other commands in Linux. grep (global regular expression print) is a command that searches for patterns in text files in Linux.

 Task Manager is the best tool to use to disable applications on startup in Windows 10. Task Manager is a built-in utility that shows the current processes, performance, and users on a system. It also has a Startup tab that lists the applications that run on boot and their impact on the system. The technician can use Task Manager to disable or enable any application on startup by right-clicking on it and selecting the appropriate option. System Configuration, Performance Monitor, and Group Policy Editor are other tools that can be used to manage system settings, but they are not as simple or convenient as Task Manager for this task. References:

A user account that belongs to the local administrator’s group has the permission to install software on a Windows machine. If a user receives a UAC (user account control) prompt when trying to install software, it means the user does not have enough privileges and needs to enter an administrator’s password or switch to an administrator’s account. Adding the user account to the local administrator’s group can resolve this issue. Configuring Windows Defender Firewall, creating a Microsoft account and disabling the guest account are not related to this issue.

The correct answer is B. Printer Properties/Sharing tab. This is the location where the technician can enable printer sharing and assign a share name for the USB printer. This will allow other computers on the network to access the printer by using the share name or the IP address of the computer that has the printer attached1.

1: CompTIA A+ Certification Exam: Core 2 Objectives, page 15, section 1.9.

The correct answer is B. Power Options. The Power Options utility in the Control Panel allows you to configure various settings related to how your computer uses and saves power, such as the power plan, the sleep mode, the screen brightness, and the battery status. To access the Power Options utility, you can follow these steps:

Go to Control Panel > Hardware and Sound > Power Options.

Click on Change plan settings for the power plan you are using.

Click on Change advanced power settings.

Expand the USB settings category and then the USB selective suspend setting subcategory.

Set the option to Disabled for both On battery and Plugged in.

Click on OK and then on Save changes.

This will prevent the operating system from suspending the USB devices to save power .

System, Devices and Printers, and Ease of Access are not the utilities that should be used to configure the setting. System is a utility that provides information about your computer’s hardware and software, such as the processor, memory, operating system, device manager, and system protection. Devices and Printers is a utility that allows you to view and manage the devices and printers connected to your computer, such as adding or removing devices, changing device settings, or troubleshooting problems. Ease of Access is a utility that allows you to customize your computer’s accessibility options, such as the narrator, magnifier, high contrast, keyboard, mouse, and speech recognition. None of these utilities have any option to configure the USB selective suspend setting.
