300-435 Question 122
Select 3A network engineer is troubleshooting intermittent packet loss in a Cisco enterprise network. The engineer decides to use streaming telemetry data to assist in identifying the issue. What are the key benefits of using telemetry data in this scenario?
- A
Telemetry data provides real-time insights into network performance and device status.
- B
Telemetry data eliminates the need for traditional SNMP polling entirely.
- C
Telemetry data allows for proactive identification of issues before they impact users.
- D
Telemetry data provides historical logs but lacks support for real-time analysis.
- E
Telemetry data can reduce the overhead associated with traditional network monitoring methods.
Show answer and explanation
Correct answers: A, C, E
Explanation
Telemetry data is a powerful tool for troubleshooting because it provides real-time updates, enables proactive monitoring, and reduces the resource overhead of traditional methods like SNMP polling. By leveraging telemetry, network engineers can quickly analyze network behavior, identify patterns, and resolve issues before they escalate.
- A. Correct.
Telemetry data provides real-time insights by streaming information from devices to a collector, enabling faster detection and troubleshooting of issues.
- B. Incorrect.
While telemetry reduces reliance on SNMP polling, it does not entirely eliminate the need for SNMP in all scenarios, especially legacy systems.
- C. Correct.
Telemetry enables proactive issue identification by continuously monitoring key network metrics and alerting administrators to anomalies.
- D. Incorrect.
This is incorrect because telemetry is specifically designed to support both real-time and historical analysis, enhancing network troubleshooting capabilities.
- E. Correct.
Telemetry reduces monitoring overhead by streaming only the necessary data efficiently, compared to the more resource-intensive traditional polling methods.
