SNCF — Securing Networks with Firepower — Question 87

Which interface type allows packets to be dropped?

Answer options

• A. passive
• B. inline
• C. ERSPAN
• D. TAP

Correct answer: B

Explanation

The correct answer is B, inline, as it allows for active monitoring and can drop packets as part of its operation. The other options, such as passive and TAP, do not have the capability to drop packets since they only monitor traffic without interfering. ERSPAN is primarily used for encapsulating and transporting packets for analysis, not for dropping them.
