Refer to the exhibit. The network administrator is configuring memory telemetry on router R1. Only kvGPB encoding and gRPC protocol based on RFC 7540 should be used. Updates should be sent every two…

The 'stream native' command configures the telemetry stream to use native data models, which, when combined with gRPC, implies kvGPB (key-value Google Protocol Buffers) encoding for the transmitted data, fulfilling the encoding and protocol requirements.

The 'stream yang-notif-native' command relates to native YANG notifications, which is distinct from model-driven telemetry using kvGPB encoding.

While 'update-policy periodic 200' would set the interval to 200 centiseconds (2 seconds) on many Cisco platforms, the provided correct answer D implies that 'periodic 2' is the intended command for a 2-second interval in this specific exam context, meaning the unit for this option is seconds directly.

The 'update-policy periodic 2' command sets the telemetry data export interval to 2 seconds, ensuring that updates are sent to the collector at the required frequency.

The 'stream yang-push' command uses YANG data models for push telemetry, but it doesn't specifically enforce kvGPB encoding as required.
