Correct answer is A, only AV, URL filtering, Wilfire & Anti spyware can block C2. Data filtering is DLP (data lost prevention) so wrong answer.

I think the correct answer is absent the correct answer "Spyware profile applied to outbound security policies" Not AV or sure Data Filtering . But AV profile may be near to the right

Wrong Use Data Filtering Profiles to prevent sensitive, confidential, and proprietary information from leaving your network. Predefined patterns, built-in settings, and customizable options make it easy for you to protect files that contain certain file properties (such as a document title or author), credit card numbers, regulated information from different countries (like social security numbers), and third-party data loss prevention (DLP) labels.

The best answer is C. Data filtering can be used for blocking uploads that match file and data pattern upload. It is explaind in PCNSA Study Guide at page 27.

Best answer is C, read PCNSA Study Guide at page 27. Because Antivirus Profile can prevent downloading spyware from internet (inboud traffic). In this question, user has been infected. Now malware establish a connection with C2 Server and leak client's data to outsite (Outbound). You can use Data Filter to prevent exfiltration. Also use Anti-spam profile but that's not listed in this question.

Selected Answer: A
Palo Alto Networks Certified Network Security Administrator Study Guide page 61 Antivirus: Includes new and updated antivirus signatures, including WildFire signatures and automatically generated command-and-control (C2) signatures. WildFire signatures detect malware seen first by firewalls from around the world. You must have a Threat Prevention subscription to get these updates. New antivirus signatures are published daily.

A. C is technically possible, but it's talking about updating signature databases, the answer is clearly hinting at the AV profile.

but you can block outbound C2 communications with traffic that matches file and data patterns with a Data filtering profile. Study Guide (July 2021 page 37) Actions on the Objective.

while this is true, the question is only asking which one will inherently prevent C2. You have to manually configure a solution in the case of answer C. Answer A will protect against this communication as the signature is updated.
