300-420 Question 299
Select 3An enterprise network administrator is evaluating the adoption of model-driven telemetry (MDT) to enhance network monitoring and performance analysis. Which of the following are impacts of implementing model-driven telemetry on the network?
- A
It provides real-time data streaming for better operational insights.
- B
It increases CPU and memory usage on network devices due to continuous data processing.
- C
It eliminates the need for traditional SNMP-based monitoring tools.
- D
It requires the network devices to support YANG models for data export.
- E
It reduces the overall network traffic by only sending data on-demand.
Show answer and explanation
Correct answers: A, B, D
Explanation
Model-driven telemetry (MDT) introduces real-time data streaming, enabling faster and more detailed operational insights. However, it increases the resource usage on devices and requires support for YANG models to define the exported data. While it enhances monitoring capabilities, it does not completely replace traditional tools like SNMP, and it can increase network traffic due to continuous data streams.
- A. Correct.
Correct: Model-driven telemetry enables real-time data streaming, allowing administrators to gain deeper and faster insights into network operations compared to traditional polling methods.
- B. Correct.
Correct: Continuous data processing and streaming can increase the CPU and memory usage on network devices, especially if telemetry is extensively configured.
- C. Incorrect.
Incorrect: While MDT can complement or reduce reliance on SNMP, it does not completely eliminate the need for traditional monitoring tools in many environments.
- D. Correct.
Correct: YANG models are essential for defining the structure and semantics of data used in model-driven telemetry. Devices must support these models to export telemetry data.
- E. Incorrect.
Incorrect: Model-driven telemetry generates continuous streams of data, which can increase network traffic compared to traditional on-demand methods like SNMP polling.
