JNCIA-SEC: Juniper Networks Certified Associate – Security (2021) — Question 33

An application firewall processes the first packet in a session for which the application has not yet been identified.

In this scenario, which action does the application firewall take on the packet?

Answer options

• A. It allows the first packet.
• B. It denies the first packet and sends an error message to the user.
• C. It denies the first packet.
• D. It holds the first packet until the application is identified.

Correct answer: A

Explanation

The correct answer is A, as an application firewall typically allows the first packet while it attempts to identify the application. Options B and C are incorrect because the firewall does not deny the packet without first identifying the application. Option D is also incorrect since the firewall does not hold the packet; it processes it to allow or deny based on application identification.
