The issue described in the question is most likely due to an incorrect configuration of the printer's duplex settings. To enable automatic duplex printing, the technician needs to read the printer's installation manual to understand how to configure the printer's duplex settings correctly. Once the settings are configured, the printer should be able to print on both sides of the paper automatically.

To fix the issue of a newly installed printer capable of automatically printing on both sides of the paper but only printing on both sides manually, the technician should read the installation manual and configure duplex settings. Duplex printing settings can be configured in the printer driver software, which can be accessed through the printer settings in the Control Panel. Installing the most recent firmware upgrade available for the printer, contacting the vendor for a hardware replacement, or reinstalling the printer software and drivers and restarting the printer will not resolve the issue.

Switches only send data to the specific computer, while hubs send data to all computers inside the network. References: CompTIA A+ Certification Exam Guide, Exam 220-1001, Page 323

Configuring scanning to a Secure Message Block (SMB) share specifically designated for executive access ensures that the scanned confidential documents are stored securely on a network drive with restricted access. SMB is a network file sharing protocol that allows applications on a computer to read and write to files and request services from server programs in a computer network. By setting up an SMB share with executive access, the data is centralized, making it easier to manage permissions and security settings. This method also utilizes the existing network infrastructure, allowing for scalability and integration with other security measures like encryption and authentication protocols.

Before creating a virtual machine (VM) on a computer, it's crucial to ensure that the CPU supports virtualization and that this feature is enabled in the BIOS (or UEFI) settings. While sufficient RAM and hard drive space are also important for running VMs effectively, and compatibility with the graphics card might be a consideration for VMs with intensive graphical requirements, the foundational step is to verify that the CPU supports virtualization and that this feature is activated in the BIOS settings. This is because virtualization technology, often referred to as VT-x (on Intel CPUs) or AMD-V (on AMD CPUs), is a prerequisite for running most virtualization software efficiently.

If a laptop does not charge when connected to a USB 3.1 docking station despite the AC adapter being plugged in, the most likely reason is that the dock is not designed to provide power passthrough. This means that the dock's primary function is connectivity for peripherals rather than power delivery to the laptop. The other options are possible but less likely if the sole issue is the absence of charging functionality when the dock and its power supply are properly connected.

The first step a technician should take before upgrading the Wi-Fi card on a laptop, or performing any internal hardware modifications, is to remove the power cable to ensure the device is not powered on. This is a crucial safety measure to prevent any electrical damage to the laptop or the technician. It also helps in avoiding any unintended changes or data loss that might occur if the device is powered on during the upgrade process.

To clean sticking keys on a laptop keyboard, using compressed air is the most effective and safest method. Compressed air can dislodge and remove crumbs, dust, and other debris from under the keys without risking damage to the keyboard's electronic components or the keys themselves. This approach is non-invasive and widely recommended for keyboard maintenance.

A network tap (Test Access Point) is a device used for monitoring network traffic. It allows the technician to passively observe the traffic between two network nodes in real-time without introducing latency or affecting the network's performance. By using a network tap, the technician can analyze the data packets flowing through the network to identify if packet loss is occurring, which could be contributing to the slow network traffic in the branch office.

References: Network taps are widely recognized in the field of network troubleshooting and monitoring for their ability to provide a mirror of the traffic that can be analyzed for issues such as packet loss.

Routers are designed to connect multiple networks and direct packets to their intended destinations across network segments. This makes them essential for directing packets to networks outside of the LAN, such as the internet or other remote networks.

RAID 10 (also known as RAID 1+0) combines the features of RAID 1 (mirroring) and RAID 0 (striping) to provide both redundancy and performance enhancements. This configuration requires a minimum of four drives and offers fast data access through striping while ensuring data redundancy through mirroring. RAID 10 is ideal for environments where both data integrity and performance are critical, such as financial databases.

Liquid cooling is an effective solution for managing the high heat output that can result from overclocking a GPU. It's more efficient than air cooling methods (like larger heat sinks or fan upgrades) and can better maintain lower temperatures under load, reducing the risk of overheating.

When a new drive is not recognized by Windows 10, and it's known that the drive was formatted before going offline, checking the file system format is crucial. Windows does not natively recognize the ext4 file system, commonly used in Linux environments. If the drive was inadvertently formatted to ext4, Windows would not display or allow access to it. The solution involves reformatting the drive to a file system that Windows recognizes, such as NTFS or FAT32, ensuring the drive becomes visible and accessible within Windows 10.

Vertical lines on a laser printer printout are most commonly associated with issues in the drum unit. The drum is a crucial component in the laser printing process, where it receives an electrostatic image of the document to be printed and transfers toner to the paper. If there are defects or damage to the drum's surface, it can result in vertical lines appearing on the printed output as the drum fails to evenly distribute toner across the page.

Two-factor authentication (2FA) significantly enhances security by requiring two forms of verification before granting access to company resources, making it harder for unauthorized users to gain access even if they have one of the credentials. PIN code enforcement adds an additional layer of security by ensuring that devices are protected by a PIN, making physical access to the device more challenging for unauthorized users. While the other options provide various benefits, 2FA and PIN code enforcement directly enhance the security of remote users accessing company resources.

Secure print is the best option to address the concern of printing confidential documents on a shared enterprise multifunction printer (MFP). Secure print requires users to enter a PIN or use an ID card at the printer to release their print jobs. This ensures that documents are only printed when the user is physically present to collect them, preventing sensitive information from being left unattended or viewed by unauthorized individuals.

While a central printer server, audit logs, and Wi-Fi direct printing have their own benefits, they do not provide the same level of immediate security for confidential documents as secure print does. A central printer server centralizes management but does not prevent unauthorized viewing. Audit logs provide a record of activity but do not prevent the initial security breach. Wi-Fi direct printing allows for a direct connection to the printer but does not secure the document during printing.
