InfoComm / AVIXA CTS-I Practice Test 2026 – Complete Exam Prep Guide

The correct answer outlines the primary steps involved in HDCP (High-bandwidth Digital Content Protection) authentication, which ensures that digital content is securely transmitted from a source device to a display. The process begins with a locality check, where the devices involved verify that they are authorized to communicate with one another. Next is the key exchange, during which the source device and the display share cryptographic keys necessary for content protection. Finally, the session exchange occurs, establishing a secure communication channel that allows for the transmission of protected content.

This sequence is crucial because it ensures that only authorized devices can access HDCP encrypted streams, thus maintaining the integrity and security of digital content across HDMI and other interfaces. Understanding this process is particularly important for professionals in the AV industry, as it directly impacts how devices are connected and how secure content delivery is managed in various installations.
