Explanation

Telemetry (A) is correct because it is the technology designed to stream operational data from network devices to a management system in real time, and it specifically uses HTTP/2 + Protobuf (gRPC-based transport) as its data collection protocol - making it ideal for high-frequency, minute-level fault detection and experience visualization in platforms like CampusInsight.

• B (HTTPS) is a general-purpose secure transport protocol, not a network monitoring technology - it has no built-in mechanism for structured device metric collection or fault correlation.
• C (KPI) refers to Key Performance Indicators, which are metrics derived from collected data, not a data collection technology itself.
• D (SNMP) (Simple Network Management Protocol) is an older polling-based protocol that collects data periodically and uses UDP, not HTTP/2 + Protobuf - it lacks the real-time streaming capability needed for minute-level fault identification.

Memory tip: Think Telemetry = Time-series Transport - it pushes streaming data using modern protocols (HTTP/2 + Protobuf), whereas SNMP pulls data on a schedule. If the question mentions real-time streaming or gRPC-style protocols, the answer is Telemetry.
