MPSK Local is a feature that can reduce the IT administration overhead associated with deploying devices that do not support 802.1X authentication while maintaining a secure environment. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require manual intervention by the installers or the MPSK gateway, or they do not provide unique pre-shared keys for devices.

Explanation
The correct answer is C. sysops.
The sysops user role is a predefined role that allows users to view switch configuration information and have access to the PUT and POST methods for REST API. The sysops user role can also use the PATCH and DELETE methods for REST API, but not for all resources. The sysops user role is suitable for users who need to perform system operations on the switch, such as backup, restore, upgrade, or reboot.
According to the AOS-CX REST API Reference basics1, one of the predefined user roles is:
* sysops: Users with this role can view switch configuration information and have access to the PUT and POST methods for REST API. They can also use the PATCH and DELETE methods for REST API, but not for all resources. Users with this role can perform system operations on the switch, such as backup, restore, upgrade, or reboot.
The other options are incorrect because:
* A. administrators: Users with this role have full access to all switch configuration information and all REST API methods. This role is more than what the customer requires.
* B. auditors: Users with this role can only view switch configuration information and have access to the GET method for REST API. They cannot use the PUT and POST methods for REST API.
* D. helpdesk: Users with this role can view switch configuration information and have access to the GET method for REST API. They can also use the PATCH method for REST API, but only for a limited set of resources. They cannot use the PUT and POST methods for REST API.

802.11mc, also known as Wi-Fi RTT (Round Trip Time), is a standard that allows wireless access points and clients to measure precise distance by calculating the round-trip time of packets between them. This enables accurate indoor location tracking - typically within 1 to 3 meters - without requiring GPS.
Some HPE Aruba Networking APs support 802.11mc, allowing retailers, healthcare, and enterprise environments to build location-aware applications for navigation, asset tracking, and analytics.

The calculated Equivalent Isotropic Radiated Power (EIRP) for AP1 is 30 dBm. EIRP is the product of the transmitter power (in dBm) and the antenna gain (in dBi) minus the cable loss (in dB). For AP1, EIRP = 10 dBm + 9 dBi -2 dB = 17 dBm. For AP2, EIRP = 11 dBm + 12 dBi -3 dB =
20 dBm.
