300-420 Question 305
Single answerAn enterprise network design team is implementing a network monitoring solution using a telemetry model. They want to ensure that time-sensitive data, such as interface statistics and CPU utilization, is sent periodically from network devices to a central collector. Which key design consideration should the team focus on to ensure proper delivery and performance of periodic publications?
- A
Configuring the appropriate sampling interval for telemetry data updates
- B
Using SNMP polling for data collection instead of telemetry
- C
Enabling periodic syslog messages for real-time updates
- D
Implementing Quality of Service (QoS) to prioritize telemetry traffic
Show answer and explanation
Correct answer: A
Explanation
In telemetry-based network monitoring, periodic publication involves sending updates at regular intervals. Configuring an appropriate sampling interval is critical to achieve this, as it determines how often data is sent to the collector. This ensures that the data remains current while minimizing unnecessary network overhead. Although QoS and other factors can improve telemetry performance, the sampling interval is the key design factor for periodic publications.
- A. Correct.
Configuring the appropriate sampling interval ensures that telemetry data is sent at regular intervals, which is critical for periodic publication and maintaining the balance between network performance and data freshness.
- B. Incorrect.
Using SNMP polling is not as efficient for periodic publication because it relies on request-response communication, which can introduce delays and increase overhead compared to telemetry.
- C. Incorrect.
Syslog messages are event-driven, not periodic, and are not suitable for time-sensitive updates like telemetry data.
- D. Incorrect.
While QoS can help prioritize telemetry traffic, it is not the primary consideration for ensuring proper periodic publications. The sampling interval is more fundamental to meeting periodic publication requirements.
