300-420 Question 264
Single answerAn enterprise network is deploying a new monitoring solution to improve visibility and manageability of its infrastructure. The network team wants to ensure efficient collection of telemetry data while reducing the overhead on network devices. Which network management technique is the most suitable for this scenario?
- A
Using SNMP polling to collect device information regularly
- B
Implementing telemetry streaming with model-driven telemetry (MDT)
- C
Relying on syslog messages for all device status updates
- D
Manually configuring devices to export logs and statistics as needed
Show answer and explanation
Correct answer: B
Explanation
Telemetry streaming using model-driven telemetry (MDT) is the best choice for this scenario because it enables efficient data collection by pushing updates directly from devices to a collector. This minimizes the overhead on network devices and ensures real-time visibility, unlike traditional methods like SNMP polling, syslog, or manual configurations, which are less scalable and efficient.
- A. Incorrect.
SNMP polling is resource-intensive and generates significant overhead, especially in large networks, making it less efficient for real-time telemetry collection.
- B. Correct.
Telemetry streaming with model-driven telemetry (MDT) allows devices to push real-time data to a collector, reducing polling overhead and improving efficiency.
- C. Incorrect.
Syslog messages are useful for logging events but are not designed for continuous telemetry data collection, limiting their scope for this scenario.
- D. Incorrect.
Manually configuring devices to export logs and statistics is inefficient and does not scale well for modern enterprise networks.
