Palo Alto Networks Certified Network Security Administrator (PCNSA) — Question 21

Which action results in the firewall blocking network traffic without notifying the sender?

Answer options

• A. Drop
• B. Deny
• C. Reset Server
• D. Reset Client

Correct answer: A

Explanation

The correct answer is 'Drop' because this action silently discards the packets without sending any notification to the sender. 'Deny' usually indicates a response back to the sender, while 'Reset Server' and 'Reset Client' involve sending reset packets, which do notify the sender that the connection has been terminated.
