With the login credentials out of the way, John was able to access the RHEL 7.3 download page. He selected the correct architecture (x86_64) and package type (DVD ISO), and then clicked the "Download" button. The ISO file began to download, and John felt a sense of satisfaction wash over him. He had successfully tracked down the elusive RHEL 7.3 ISO.
Absolutely not. Beyond legality, you cannot trust the integrity. It would be negligence to run such an image in any professional environment.
Use the version dropdown menu to locate 7.3 . You will typically find options for the "Binary DVD" (for a full offline install) and the "Boot ISO" (for network-based installs).
