300-445 Question 85
Select 2An enterprise network has multiple branch locations. The IT team wants to implement a data collection solution to monitor network health, application performance, and device status. The solution must scale efficiently, collect telemetry data in near real-time, and provide centralized visibility. Which of the following methods should the team implement?
- A
SNMP polling for frequent device status checks
- B
Streaming telemetry using gRPC with model-driven data
- C
Syslog collection for all device logs
- D
NetFlow or IPFIX data export for traffic analysis
- E
Periodic CLI-based data collection using scripts
Show answer and explanation
Correct answers: B, D
Explanation
To achieve near real-time data collection, scalability, and centralized visibility, streaming telemetry using gRPC and NetFlow/IPFIX data export are the most appropriate solutions. Streaming telemetry provides live updates on device health and performance metrics, while NetFlow/IPFIX enables traffic analysis at scale. SNMP, syslog, and CLI-based methods are less efficient or not designed for the required level of performance.
- A. Incorrect.
SNMP polling is not suitable for near real-time monitoring due to its limited scalability and polling interval delays.
- B. Correct.
Streaming telemetry using gRPC with model-driven data is highly efficient, scalable, and provides near real-time telemetry data, meeting the requirements of the scenario.
- C. Incorrect.
Syslog collection is useful for event logging but is not designed for continuous performance monitoring or near real-time telemetry.
- D. Correct.
NetFlow or IPFIX data export is a scalable method for analyzing traffic patterns and can complement telemetry solutions for centralized visibility.
- E. Incorrect.
Periodic CLI-based data collection using scripts is not efficient for large-scale, near real-time monitoring as it is manual and lacks scalability.
