Which of the following is NOT a valid license type? (Select Two)

In the context of Aruba's licensing structure, "Application Security" does not represent a valid license type within their typical offerings. Aruba's licensing model primarily includes categories that are focused on delivering core functionalities associated with the Aruba Operating System (AOS) and its associated features, which are essential for effective network management and security.

On the other hand, "Base AOS" is a recognized entry-level license necessary for activating the standard features of the Aruba Operating System. "Standard AOS" generally includes a broader set of capabilities and functionalities than the base license, targeting more extensive operational needs. "Security Trust" is also a valid category that aligns with Aruba's emphasis on secure networking solutions, but it may be less commonly referenced than the AOS-related licenses.

Thus, identifying "Application Security" as a non-valid license type aligns with the overall understanding of how Aruba structures its licensing framework, focusing on AOS and its associated components instead.
