Why each option

Industry research consistently shows that organizations take an average of roughly 50 days to detect a breach, highlighting the need for continuous monitoring and threat intelligence.

A70

70 days overstates the specific average referenced in Cisco certification materials for this metric.

B50Correct

Cisco and partner research (including Cisco Annual Security Reports) has cited approximately 50 days as the average dwell time before a breach is discovered, underscoring how attackers can operate undetected for weeks inside a network.

C10

10 days dramatically understates the real-world dwell time; most organizations lack the detection capabilities to identify breaches that quickly.

D30

30 days is below the cited average and does not match the statistic used in Cisco security awareness training.
