300-435 Question 98
Select 3You are tasked with configuring model-driven telemetry (MDT) on an IOS XE device to monitor interface statistics and stream the data to a collector using NETCONF. Which of the following steps should you perform to correctly configure the telemetry subscription?
- A
Define the sensor path for interface statistics.
- B
Configure the subscription using the CLI and specify YANG push as the encoding format.
- C
Use the NETCONF
operation to dynamically create the telemetry subscription. - D
Specify the data collector's IP address and port in the subscription configuration.
- E
Enable SNMP traps on the device to support model-driven telemetry.
Show answer and explanation
Correct answers: A, C, D
Explanation
To configure a model-driven telemetry subscription on an IOS XE device, you must define a sensor path, specify the destination collector's details (IP and port), and create the subscription using either CLI or NETCONF. For NETCONF-based dynamic subscriptions, the
- A. Correct.
Correct: Defining the sensor path is necessary to specify which data the telemetry subscription will monitor (e.g., interface statistics). This is a fundamental step in configuring MDT.
- B. Incorrect.
Incorrect: Subscriptions configured via CLI do not use YANG push encoding. YANG push is used in NETCONF for dynamic subscriptions, not CLI-based subscriptions.
- C. Correct.
Correct: The NETCONF
operation allows dynamic creation of telemetry subscriptions, which is a valid method for configuring MDT using NETCONF. - D. Correct.
Correct: The subscription must include the IP address and port of the telemetry data collector to ensure the data is streamed to the correct destination.
- E. Incorrect.
Incorrect: SNMP traps are not required for model-driven telemetry. MDT operates independently of SNMP and uses streaming protocols such as gRPC or NETCONF.
