300-445 Question 84
Select 3You are designing a network assurance solution for an enterprise that wants to collect network telemetry data for performance analysis and troubleshooting. The enterprise network includes devices from multiple vendors, and the solution must support real-time data collection and integration into a centralized monitoring platform. Which of the following options should you consider for implementing data collection?
- A
Use SNMP polling to gather device metrics at regular intervals
- B
Implement gRPC-based streaming telemetry for real-time data collection
- C
Rely on syslog messages for detailed performance data
- D
Leverage NetFlow or IPFIX for traffic flow analysis
- E
Utilize CLI screen scraping to extract data from devices
Show answer and explanation
Correct answers: A, B, D
Explanation
To implement an effective data collection strategy for network assurance, it is essential to utilize methods that are scalable, real-time, and capable of supporting multi-vendor environments. SNMP is useful for periodic polling, gRPC streaming telemetry is ideal for real-time data collection, and NetFlow/IPFIX provides critical insights into traffic patterns. Syslog and CLI screen scraping are less suitable for the required use case.
- A. Correct.
SNMP polling is a widely used method for collecting device metrics, but it may not provide real-time updates. However, it is still relevant for periodic data collection.
- B. Correct.
gRPC-based streaming telemetry is designed for real-time data collection and is vendor-agnostic, making it an ideal choice for modern network assurance solutions.
- C. Incorrect.
Syslog messages are primarily used for logging events and alerts, not for detailed performance or telemetry data collection.
- D. Correct.
NetFlow or IPFIX is specifically designed for traffic flow analysis, which provides valuable insights into network performance and anomalies.
- E. Incorrect.
CLI screen scraping is an outdated and unreliable method for data collection, especially in networks with devices from multiple vendors.
