What is the default number of sensors active per subnet?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

Two sensors active per subnet by default. This setup provides redundancy and helps balance the monitoring load across the subnet. With two active sensors, if one encounters an issue, the other can continue collecting data without interruption, while still handling traffic without overloading a single sensor. Having only one sensor would create a single point of failure, and having three or four active sensors goes beyond the default configuration and isn’t necessary unless your environment needs additional capacity or fault tolerance.
