According to the web search results, TCP/443 is the port that must be allowed on your company's firewall for AP access to the Mist cloud.TCP/443 is the port that is used for HTTPS, which is a secure version of HTTP that encrypts the data sent between the client and the server1.Mist APs use HTTPS to communicate with the Mist cloud and receive their configuration, firmware, and policies2.TCP/443 is also the port that is used for ep-terminator, which is a service that provides encrypted tunneling between Mist APs and the Mist cloud3. Therefore, TCP/443 is the port that must be allowed on your company's firewall for AP access to the Mist cloud.

According to theMist Access Pointspage, the BT11 is a dedicated device for location-based services (LBS) in the Mist Access Point portfolio1.The BT11 is a battery-powered Bluetooth Low Energy (BLE) beacon that can be used to enhance the accuracy and reliability of indoor location services1.The BT11 can be placed in areas where Mist APs are not available or where additional BLE coverage is needed1.The BT11 can be managed by the Mist cloud and integrated with the Mist AI platform for analytics and automation1.

The protocol that the REST API uses isHTTP. HTTP stands for Hypertext Transfer Protocol and is a standard protocol for exchanging information between different applications or services over the internet. HTTP defines a set of methods, such as GET, POST, PUT, and DELETE, that specify the type of action to be performed on a resource. HTTP also defines a set of status codes, such as 200 OK, 404 Not Found, and 500 Internal Server Error, that indicate the outcome of the request.

The REST API is an application programming interface that conforms to the design principles of the REST, or representational state transfer, architectural style. REST APIs provide a flexible, lightweight way to integrate applications and to connect components in microservices architectures. REST APIs rely on HTTP to transfer a representation of the state of the resource to the requester or endpoint. The representation can be in various formats, such as JSON, XML, HTML, or plain text.

The correct answer is D. the Mist location SDK.vBLE engagement is a feature that uses virtual Bluetooth LE (vBLE) technology and cloud-based machine learning to send personalized notifications and offers to users based on their location and preferences1.vBLE engagement works on transmit mode, which means that the Juniper Mist APs transmit vBLE signals to the users' devices, and the devices use the Mist location SDK to calculate their own location and receive the notifications1.The Mist location SDK is a software development kit that allows developers to integrate the vBLE engagement feature into their own mobile applications1.The Mist location SDK can achieve 1 m to 3 m accuracy using the vBLE signals from the APs1.

According to the web search results, Mist detects rogue APs by using the AP's third dedicated radio, which is used for scanning the wireless spectrum and detecting unauthorized APs on both 2.4 GHz and 5 GHz radio bands1.A rogue AP is an unauthorized access point that is installed on a network without the knowledge or consent of the network administrator1.A rogue AP can pose a serious security threat to a network, as it can allow attackers to bypass the network's security policies and gain access to sensitive data or launch other attacks1.A rogue AP can also interfere with the performance of the legitimate APs and cause network congestion or degradation1.

Mist APs have three radios: one for 2.4 GHz, one for 5 GHz, and one for scanning1.The scanning radio is used for detecting rogue, neighbor, and honeypot APs on both 2.4 GHz and 5 GHz radio bands1.This means that regardless of which radios you have enabled on your AP (2.4 GHz or 5 GHz), it will still be able to detect unauthorized APs at any frequency using the scanning radio1.The scanning radio can also provide other benefits, such as monitoring the network performance, optimizing the channel selection, and enhancing the location services1.

Therefore, based on the web search results, Mist detects rogue APs by using the AP's third dedicated radio, which is used for scanning the wireless spectrum and detecting unauthorized APs on both 2.4 GHz and 5 GHz radio bands.
