Which of the following is the EASIEST way to centrally deploy software?

A network share allows administrators to place software installation packages on a central server, making them accessible to multiple client machines over the network for manual or scripted installation. This approach simplifies distribution compared to physical media or complex deployment systems.

PXE (Preboot Execution Environment) is primarily used for network-based operating system deployment, which is a more complex setup than simply making software available on a share.

USB drives are a manual, physical method that requires direct interaction with each machine, which is not a central deployment method for many devices.

Optical media (CD/DVD) is a manual, physical method requiring individual disc insertion for each machine, which is neither central nor easy for large-scale deployments.
