Automatic Private IP Addressing (APIPA) allows a Windows PC to automatically assign itself an IP address in the range of 169.254.0.1 to 169.254.255.254 when it's unable to obtain an IP address from a DHCP server. This feature is particularly useful in situations where the PC cannot connect to the network or when DHCP services are unavailable. While APIPA addresses are not routable and thus not suited for large networks, they enable basic networking functionality for small ad-hoc or local networks.

The appropriate power supply specification for the described workstation setup is 12V, 500W output. This specification ensures that the power supply can handle the combined power requirements of an ATX motherboard, multi-core processor, dedicated graphics solution, SATA hard drive, and DDR4 memory. The 12V rail is crucial for components such as the CPU and graphics card, while a 500W output provides sufficient power overhead to support the system under load, as well as potential future upgrades or additional components.

Badging is a form of authentication that requires employees to use a badge or ID card to release print jobs. This solution reduces unnecessary printing by ensuring only authorized users print.

Why Not A (Access control list): While ACLs manage permissions, they are not used for physical authentication at printers.

Why Not B (Audit logging): Audit logs track actions but do not restrict printer access.

Why Not D (Print server): A print server manages print jobs but doesn’t enforce authentication.
