正解:A
The telemetry information consists of three types of data:
+ Flow information: This information contains details about endpoints, protocols, ports, when the flow started, how long the flow was active, etc.
+ Interpacket variation: This information captures any interpacket variations within the flow. Examples include variation in Time To Live (TTL), IP and TCP flags, payload length, etc
+ Context details: Context information is derived outside the packet header. It includes details about variation in buffer utilization, packet drops within a flow, association with tunnel endpoints, etc.
