300-420 Question 300
Select 3An enterprise network is experiencing challenges with effectively monitoring the performance of its devices and applications. The network team is considering implementing model-driven telemetry (MDT) to address these issues. Which benefit(s) of MDT would have the most positive impact in this scenario?
- A
Real-time streaming of data from network devices to collectors
- B
Reduction in polling overhead compared to traditional SNMP methods
- C
Ability to modify device configurations directly from the telemetry stream
- D
Standardized data models for consistent and structured data collection
- E
Improved network security by encrypting telemetry data at rest
Show answer and explanation
Correct answers: A, B, D
Explanation
Model-driven telemetry (MDT) addresses performance monitoring challenges by providing real-time, structured data streaming from network devices, reducing the overhead of traditional polling mechanisms, and using standardized data models for efficient analysis. These features collectively improve visibility into network performance and simplify troubleshooting.
- A. Correct.
Real-time streaming allows the network team to monitor performance issues as they occur, offering proactive insights into the network state. This is a key advantage of MDT.
- B. Correct.
Model-driven telemetry reduces the load on network devices by replacing traditional polling methods like SNMP with a more efficient push model, which enhances performance monitoring.
- C. Incorrect.
Telemetry streams are read-only and are designed for monitoring purposes. They do not provide the capability to modify device configurations directly.
- D. Correct.
Standardized data models, such as YANG, ensure consistent and structured data collection across devices, making it easier to parse and analyze telemetry data.
- E. Incorrect.
While encryption of telemetry data is important for security, it is not a direct benefit of MDT in addressing performance monitoring challenges.
