Reference:
According to the official Mist documentation1, wireless packet captures are helpful when trying to dissect and dig down into the root cause of any wireless issue between a client and AP. You can determine if packets being sent are actually reaching their destination as well as identify if packets are corrupted. With the enhanced packet capture flow, Mist also introduced the ability to capture packets on the wired side of your network as well. This data is captured from the Eth0 port of your AP, and will examine the packets between the AP and the rest of your wired network. This includes any RADIUS, DHCP, or DNS servers you have set up.
The Mist UI does not support BLE packet capture or packet capture on cloud uplink.

Which protocol does the REST API use?
- A. SSL
- B. syslog
- C. HTTP
- D. SNMP
正解：C
解説：
Reference:
The protocol that the REST API uses is HTTP. 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.
