Palo Alto Networks (PANW) Certified Network Security Administrator (PCNSA) Practice Exam

What does the term "decoder action" refer to in the context of a Palo Alto firewall?

1. The method by which files are scanned for threats

2. The action taken when a virus is detected in a file

3. The procedure for allowing file downloads

4. The level of inspection performed on network traffic

The correct answer is: The action taken when a virus is detected in a file

In the context of a Palo Alto firewall, the term "decoder action" specifically relates to the action taken when a file is detected to contain a virus or malicious content. When a Palo Alto firewall inspects files, it uses decoders to identify and analyze file data, looking for signatures or behaviors consistent with known threats. If a virus is detected during this analysis, the decoder action dictates how the firewall will respond, such as blocking the file or quarantining it for further inspection. This understanding is crucial for maintaining security within a network, as it directly impacts how threats are managed in real time. Effective decoder actions help ensure that malicious files do not compromise network integrity or security, allowing organizations to respond swiftly to outbreaks or security incidents. Thus, the focus on the specific action that occurs when a virus is found directly aligns with the concept of "decoder action."
