300-435 Question 96
Select 3You are tasked with configuring model-driven telemetry on an IOS XE device using NETCONF. The requirement is to stream interface statistics to a collector at 10-second intervals using gRPC. Which of the following steps are required to achieve this configuration?
- A
Define a telemetry subscription specifying the sensor path and streaming frequency.
- B
Enable NETCONF-YANG on the IOS XE device.
- C
Configure a gRPC dial-out destination for the collector.
- D
Use RESTCONF to validate the telemetry subscription.
- E
Install a custom YANG model specific to interface statistics.
Show answer and explanation
Correct answers: A, B, C
Explanation
To configure model-driven telemetry on an IOS XE device using NETCONF, you need to define a telemetry subscription to specify the data and frequency, enable NETCONF-YANG for device communication, and configure a gRPC destination to send the data. RESTCONF and custom YANG models are not required for this scenario.
- A. Correct.
Defining a telemetry subscription with the sensor path and frequency is mandatory to specify what data to stream and how often.
- B. Correct.
Enabling NETCONF-YANG is necessary for the device to support NETCONF-based operations, including telemetry configuration.
- C. Correct.
A gRPC dial-out destination must be configured to send the telemetry data to the collector.
- D. Incorrect.
RESTCONF is not required for validating telemetry subscriptions when using NETCONF. NETCONF itself can be used for validation.
- E. Incorrect.
Installing a custom YANG model is not necessary for telemetry, as IOS XE already provides built-in YANG models for interface statistics.
