300-445 Question 86
Select 4An enterprise network team is tasked with implementing a network assurance solution to monitor and analyze data from multiple network devices in real-time. The solution needs to collect telemetry data, including flow data, device metrics, and logs, to ensure comprehensive coverage. Which of the following methods should be implemented to meet the requirements?
- A
Enable model-driven telemetry (MDT) on supported devices to stream telemetry data to a collector
- B
Configure SNMP polling to periodically retrieve device metrics
- C
Implement Syslog to collect event logs from network devices
- D
Use NetFlow or IPFIX protocols to gather flow data from network devices
- E
Deploy FTP servers for devices to upload configuration snapshots regularly
Show answer and explanation
Correct answers: A, B, C, D
Explanation
Comprehensive network assurance requires collecting various types of telemetry data, including device metrics, logs, and flow information. Model-driven telemetry (MDT), SNMP, Syslog, and NetFlow/IPFIX are essential methods for achieving this. FTP servers, however, are not designed for real-time data collection and are irrelevant in this context.
- A. Correct.
Model-driven telemetry (MDT) is a modern and efficient approach to streaming telemetry data directly from devices in real-time. It is highly suitable for collecting device metrics and telemetry data.
- B. Correct.
SNMP polling is a traditional method for collecting device metrics and operational data. While it may not be as efficient as MDT, it can still be used to monitor network devices.
- C. Correct.
Syslog is widely used to collect and centralize event logs from network devices for troubleshooting and monitoring purposes, making it a key part of network assurance.
- D. Correct.
NetFlow and IPFIX are industry-standard protocols for collecting and analyzing flow data, which is critical for understanding traffic patterns and network behavior.
- E. Incorrect.
FTP servers are not suitable for real-time telemetry data collection or network assurance. They are typically used for file transfers, such as configuration backups, rather than monitoring or analytics.
