iMaster NCE-FabricInsight uses telemetry for performance metric collection, offering advanced monitoring in Huawei's CloudFabric Solution. Let's evaluate each option:
A . Efficient transmission: This is true. Telemetry uses streaming data (e.g., gRPC) to reduce overhead compared to traditional polling, enabling efficient transmission of metrics. TRUE.
B . Quasi-real-time data collection: This is true. Telemetry provides near-real-time data (e.g., sub-second updates), improving responsiveness over periodic SNMP polling. TRUE.
C . Intelligent data analysis and automated troubleshooting: This is false. While FabricInsight performs intelligent analysis, automated troubleshooting is a feature of the broader iMaster NCE platform, not specifically a telemetry advantage. Telemetry enables data collection, not the automation itself. FALSE.
D . One-off subscription and continuous data push: This is true. Telemetry operates on a subscription model where a one-time setup leads to continuous data push from devices, reducing manual intervention. TRUE.
Thus, A, B, and D are advantages of telemetry-based performance metric collection.
