The correct answer is D. telemetry model-driven. To implement gRPC dial-out for real-time network monitoring on an ASR router, the engineer must enable model-driven telemetry, which is the underlying technology for this push-based data streaming.
Question
A service provider requires continuous real-time network monitoring to provide reliable SLAs to its customers. To satisfy this requirement, a network administrator is implementing gRPC dial out on an ASR with TLS. Receiver 192.168.10.2 will be assigned one of the subscriptions, and it will manage the ASR. Which configuration must the engineer apply to the router as part of the configuration process?
Options
- Asnmp-server community public
- Btelemetry model-driven
- Csnmp-server community public
- Dtelemetry model-driven

Why each option
To implement gRPC dial-out for real-time network monitoring on an ASR router, the engineer must enable model-driven telemetry, which is the underlying technology for this push-based data streaming.
The command `snmp-server community public` configures SNMP, which is a legacy, pull-based monitoring protocol and is not related to the modern push-based gRPC dial-out (model-driven telemetry) specified.
This choice is syntactically identical to choice D, which is the correct answer. The exact distinction in the original question cannot be determined from the provided text.
The command `snmp-server community public` configures SNMP, which is a legacy, pull-based monitoring protocol and is not related to the modern push-based gRPC dial-out (model-driven telemetry) specified.
The question specifies implementing 'gRPC dial out' on an ASR for continuous real-time monitoring, which is a key feature of model-driven telemetry (MDT). The command `telemetry model-driven` is fundamental to enabling MDT on Cisco IOS XR devices like ASRs. This command activates the necessary services and infrastructure for streaming operational data using protocols like gRPC dial-out, allowing the receiver (192.168.10.2) to subscribe and manage the ASR with real-time data feeds.
