300-445 Question 83
Select 2An enterprise network team is tasked with implementing a data collection strategy to monitor application performance and network health. The team decides to use streaming telemetry for real-time data collection. Which two considerations are critical to ensuring the success of the implementation?
- A
Ensure that network devices support telemetry protocols such as gRPC or NETCONF.
- B
Use SNMP polling at regular intervals to collect real-time data.
- C
Deploy a centralized data collector capable of processing high volumes of streaming telemetry data.
- D
Enable only critical telemetry sensors to minimize the performance impact on network devices.
- E
Configure the telemetry system to store data on each network device for long-term analysis.
Show answer and explanation
Correct answers: A, C
Explanation
Streaming telemetry is a modern approach to data collection that provides real-time, high-volume data for network monitoring and application performance. To implement this effectively, network devices must support telemetry protocols like gRPC or NETCONF to enable data streaming. Additionally, a centralized data collector is critical to handle and process the large volumes of telemetry data, ensuring the system is functional and scalable. Other options, such as relying on SNMP or local storage, are not aligned with the principles of streaming telemetry.
- A. Correct.
Network devices must support telemetry protocols such as gRPC or NETCONF to enable real-time streaming telemetry. Without this, the implementation cannot function.
- B. Incorrect.
SNMP polling is not designed for real-time data collection. It operates on a request-response model and is typically slower and less efficient compared to telemetry.
- C. Correct.
A centralized data collector is essential for processing high volumes of telemetry data and ensuring scalability and performance.
- D. Incorrect.
While minimizing performance impact is important, disabling too many sensors may lead to insufficient data for effective monitoring.
- E. Incorrect.
Telemetry systems are designed to send data to collectors for processing and analysis, not to store data locally on network devices for long-term analysis.
