   A data center team wants to use Grafana to monitor telemetry data from multiple Junos devices. They need to create a dashboard that shows a summary of all devices and allows them to click on a device to see detailed metrics. What is the best way to achieve this in Grafana?

   • AUse Grafana's templating feature to create a variable for device selection
   • BUse Grafana's annotation feature to mark device events
   • CCreate a separate dashboard for each device
   • DUse Grafana's alerting feature to notify on device issues

   When using Grafana to visualize telemetry data, what is typically required as a data source?

   • AA time-series database that stores the telemetry data.
   • BA web server that hosts the telemetry data as static files.
   • CA direct connection to the Junos device's CLI.
   • DA syslog server that receives telemetry logs.

   For monitoring interface traffic utilization to detect potential congestion trends, which telemetry data type is most appropriate?

   • APeriodic telemetry, because it provides regular, predictable updates of traffic counters.
   • BAny of the above, because all telemetry types provide the same data.
   • COn-change telemetry, because it sends data only when the utilization changes.
   • DEvent-driven telemetry, because it sends data only when congestion is detected.

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

   • AIt defines the data model for telemetry data, such as YANG modules.
   • BIt encrypts telemetry data to ensure security during transmission.
   • CIt provides a web-based interface for visualizing telemetry data.
   • DIt provides a transport mechanism for streaming telemetry data between the device and collector.

   What is a primary benefit of streaming telemetry compared to traditional polling-based network monitoring?

   • AIt eliminates the need for a dedicated collector because data is stored directly on the network device.
   • BIt requires less network bandwidth because data is compressed before transmission.
   • CIt provides real-time, push-based data delivery that scales more efficiently for large numbers of devices and high-frequency data.
   • DIt uses SNMP traps exclusively to notify the network management system of critical events.
