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.

BSS coloring is a mechanism that allows Wi-Fi 6 devices to mark each frame with a color code that identifies the BSS (Basic Service Set) it belongs to. This helps differentiate between frames from different BSSs that share the same channel and avoid unnecessary collisions and backoffs.
BSS coloring also introduces an adaptive threshold for interference, which means that Wi-Fi 6 devices can adjust the signal strength value that determines whether a channel is busy or not based on the current network environment. This allows for more efficient use of spectrum and higher throughput in dense scenarios.

These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively.
WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work.

The correct configuration for OSPF adjacency over SVI 10 with LAG 1 to a neighboring device is shown in Option C.
The configuration includes the following steps:
* Create a VLAN 10 and assign it a name and an IP address.
* Create a LAG 1 and assign it a name and a mode of dynamic or static.
* Add member ports to LAG 1 and enable the LAG interface.
* Assign VLAN 10 as the untagged VLAN for LAG 1.
* Enable OSPF on the switch and assign it a router ID.
* Create an OSPF area 0 and add SVI 10 as an interface in that area.
Option A is incorrect because it does not enable OSPF on the switch or create an OSPF area.
Option B is incorrect because it assigns VLAN 10 as the tagged VLAN for LAG 1, which is not compatible with SVI 10.
Option D is incorrect because it does not add member ports to LAG 1 or enable the LAG interface.

The capability that enables plug-and-play provisioning of access points in an HPE Aruba network is the UCC Service. The UCC Service is a cloud-based service that allows the access points to automatically discover and connect to the Aruba Central management platform without any manual intervention. The UCC Service also provides zero-touch configuration, firmware updates, and monitoring for the access points.
