A logistics hub design review asks the team to label active measurement and passive measurement correctly before the monitoring design is approved. Which statement is accurate?
Select an answer to reveal the explanation.
Short Explanation
Active measurement is a scout you send down the road, and passive measurement is you counting the trucks already rolling past the gate. You send probes in the active case, and you watch real traffic in the passive case. A backup file or a scripted login is not either of those two labels.
Full Explanation
Active measurement injects probes and observes how those probes fare, while passive measurement observes traffic that users and applications are already sending. A design review that asks for both labels needs that pairing: probes on the active side, real traffic on the passive side. Swapping the labels treats observation of live flows as active and probe injection as passive, which reverses the two methods and will send the design down the wrong path. A saved device configuration and its backup file record how a device is set, and neither one is a measurement method that sends probes or watches live traffic. A synthetic login to the hub portal is a scripted transaction with its own session, and offering it as a stand-in does not name active or passive measurement. Exam caveat: RFC 7799 is the document that defines these active and passive metric methods, and a design review still has to use the words the same way. Operational check: in the approved design, mark each job as probe-generating or as a copy of live traffic, and confirm the labels match what the job actually does.
