In a Campus AP deployment with a third-party firewall, which traffic must be allowed for the AP to boot successfully? (Select Two)

In a Campus Access Point (AP) deployment, certain types of traffic are essential for the AP to boot successfully and operate correctly. Among the options provided, PAPI (Platform API) is critical because it facilitates communication between the AP and the controller. This protocol is responsible for important functions such as configuration and management of the AP, and without it, the AP would not be able to establish a secure connection to the controller on the network after booting up.

In addition to PAPI, GRE (Generic Routing Encapsulation) traffic is also necessary in this context. GRE is used for encapsulating a wide variety of network layer protocols within virtual point-to-point links and is commonly employed for tunneling traffic in the Aruba architecture, especially for transporting control and data traffic between the APs and the controller. The proper flow of GRE traffic is essential for the AP to establish communication with the network infrastructure following successful boot-up.

While FTP and HTTP traffic can be used for other purposes such as software updates and configuration management, they are not essential for the initial boot process of an AP in a Campus deployment scenario. Hence, PAPI and GRE are the correct options, as they are directly related to the AP's ability to boot and communicate with the controller.
