300-445 Question 88
Select 2Your organization is designing a network assurance solution to monitor performance and detect anomalies. As part of the implementation, you need to ensure comprehensive data collection from network devices. Which of the following methods should you implement to collect telemetry data in real-time while minimizing resource consumption on network devices?
- A
Implement SNMP polling at regular intervals.
- B
Enable streaming telemetry using gRPC.
- C
Configure NetFlow for flow-based traffic analysis.
- D
Deploy syslog for event logging.
- E
Activate IP SLA for synthetic traffic monitoring.
Show answer and explanation
Correct answers: B, C
Explanation
Streaming telemetry and NetFlow are both efficient methods for collecting network data in real-time while minimizing resource overhead on devices. Streaming telemetry provides granular insights by pushing data actively, whereas NetFlow captures flow-based traffic statistics for analysis. These methods complement each other in achieving comprehensive network assurance.
- A. Incorrect.
SNMP polling is a traditional method for data collection and can be resource-intensive on network devices. It is not optimized for real-time telemetry.
- B. Correct.
Streaming telemetry using gRPC provides real-time data collection with lower resource consumption compared to legacy methods like SNMP.
- C. Correct.
NetFlow is suitable for flow-based traffic analysis and helps collect detailed telemetry data without significant overhead on the network devices.
- D. Incorrect.
Syslog is primarily used for event logging and is not a method for collecting real-time telemetry data.
- E. Incorrect.
IP SLA is used for generating synthetic traffic to measure performance metrics like latency and jitter, but it is not a telemetry data collection method.
