300-445 Question 29
Select 2An enterprise network administrator is tasked with implementing monitoring techniques to ensure optimal network performance and troubleshoot issues. The administrator needs to decide between active and passive monitoring based on the organization's requirements. Which of the following statements is true regarding active and passive monitoring as described in RFC 7276 and RFC 7799?
- A
Active monitoring generates synthetic traffic to measure network performance metrics like latency and packet loss.
- B
Passive monitoring measures network performance by injecting additional traffic into the network and analyzing its behavior.
- C
Active monitoring cannot provide real-time insights into application behavior or end-user experience.
- D
Passive monitoring relies on analyzing existing network traffic without introducing additional load to the network.
Show answer and explanation
Correct answers: A, D
Explanation
Active and passive monitoring are two distinct techniques for network performance assurance. Active monitoring generates synthetic traffic to measure specific metrics, such as latency and packet loss. In contrast, passive monitoring analyzes existing traffic, providing insights without adding network load. Both methods have unique use cases, with active monitoring being more intrusive and passive monitoring being less disruptive.
- A. Correct.
Active monitoring involves generating synthetic traffic to test and measure specific network performance metrics, as defined in RFC 7276 and RFC 7799. This is a correct description of active monitoring.
- B. Incorrect.
This statement inaccurately describes passive monitoring. Passive monitoring does not involve injecting additional traffic; it analyzes existing traffic to gather insights.
- C. Incorrect.
This statement is incorrect. Active monitoring can provide real-time insights into network behavior but at the cost of additional traffic, as it generates synthetic probes.
- D. Correct.
Passive monitoring, as defined in RFC 7276 and RFC 7799, analyzes existing network traffic without creating additional load, making this statement accurate.
