   A network engineer is troubleshooting why telemetry data is not being received. They have verified the sensor, export profile, and destination are correct. They also confirmed the collector is listening on the expected port. What should they check next?

   • AWhether the device's firewall is blocking the telemetry traffic
   • BWhether the device has enough memory
   • CWhether the collector is using the correct protocol
   • DWhether the sensor is using the correct path

   What is the role of gNMI in Juniper's streaming telemetry?

   • AIt is a data encoding format used to serialize telemetry data.
   • BIt defines a standard protocol for managing and streaming telemetry data from network devices.
   • CIt provides a graphical interface for configuring telemetry sensors.
   • DIt is a proprietary Juniper protocol for telemetry data collection.

   A large data center is experiencing network issues that are difficult to diagnose with traditional polling. They need to capture high-frequency data for short periods to troubleshoot, but they are concerned about the storage and bandwidth impact of continuous telemetry. They also need to ensure the data is secure. Which approach best balances these requirements?

   • AUse a hybrid approach: periodic telemetry with a 100-millisecond interval during troubleshooting windows, and event-driven telemetry otherwise, with gRPC and TLS
   • BUse event-driven telemetry to capture data only when anomalies are detected, and use gRPC with TLS for secure transport
   • CEnable periodic telemetry with a 1-second interval for all interfaces, and store data in a time-series database
   • DEnable on-change telemetry for all interfaces, and use gRPC with TLS for secure transport

   What is the role of the Management daemon (mgd) in Juniper's telemetry architecture?

   • AIt stores telemetry data in a local database for historical analysis.
   • BIt processes and exports telemetry data to external collectors.
   • CIt provides a CLI for monitoring telemetry data in real-time.
   • DIt handles the configuration of telemetry sensors and export profiles.
