Port 20 is used for FTP data transfer (along with port 21 for control), so enabling this port is required. Ports 23, 53, and 68 are unrelated to FTP functionality, as they correspond to Telnet, DNS, and DHCP respectively.

The CMOS (complementary metal-oxide-semiconductor) is a small chip on the motherboard that stores the BIOS settings, including the date and time. The CMOS battery is a coin cell battery that provides power to the CMOS chip when the computer is turned off, so that the BIOS settings are not lost. If the CMOS battery is discharged, the CMOS chip will lose its data, and the date and time will be reset to the default values. This will cause a message to display indicating that the date and time are incorrect when the computer is turned on. The other computers on the network do not display this message because they have functional CMOS batteries. The most likely cause of this issue is the CMOS battery is discharged, and it needs to be replaced with a new one.

Explanation
By requiring a code or badge before releasing a print job, it ensures that only authorized personnel can collect the printouts. This method is effective in preventing waste and in keeping sensitive documents confidential.
Sending reminders, enabling duplex printing, and billing departments are useful strategies for reducing paper utilization but may not necessarily prevent waste caused by uncollected printouts.
Requiring a code or badge before releasing a print job is the best solution to prevent the waste of printed materials, as it ensures that only the user who initiated the print job is able to pick up the printed materials.
This can be achieved by implementing print release software or requiring users to enter a PIN code at the printer. References: CompTIA A+ Certification Exam Objectives 1001, 2.10

A virtual Trusted Platform Module (vTPM) is a technology that can be used to harden guest virtual machines by providing them with a secure cryptographic device. A vTPM can store encryption keys, certificates, and passwords, and can perform integrity checks on the guest operating system and applications. A vTPM can also enable features such as BitLocker and Credential Guard in Windows 10 virtual machines.

When a device is experiencing slow file transfers to an external USB drive and the physical connections are confirmed to be correct, the next step is to update the device drivers. Outdated or corrupt drivers can cause suboptimal performance and slow transfer speeds. Updating the drivers can resolve these issues and improve the device's communication with the USB drive, leading to faster file transfers.
