A network team is configuring Telegraf to collect gNMI telemetry from devices and store it in InfluxDB. They have a large number of devices and want to ensure that the data is collected efficiently. They are considering using multiple Telegraf instances. Which approach would best distribute the load while maintaining a single InfluxDB database?

Use multiple InfluxDB databases, one per Telegraf instance

Run a single Telegraf instance with all devices configured

Run multiple Telegraf instances, each configured with a subset of devices, all writing to the same InfluxDB

Use gNMIc to collect data and write directly to InfluxDB, bypassing Telegraf

A network engineer is using gNMIc to subscribe to telemetry data and wants to output the data in JSON format to a file for later analysis. Which gNMIc output configuration should be used?

stdout output with format protobuf

influxdb output with format json

Telemetry Tools (gNMIc, TIG Stack) JN0-423 Practice Questions (Page 2)

Part of the gRPC domain, which makes up ~29% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~10–17 in this domain), expect 2–3 from this objective — we provide 35 practice questions to prepare you well beyond it.
