Question 1

A change request at Coho Winery states that the team must analyze suspicious files that are not known good or known malicious. What is the best response?

• Use DNS Security logs and related endpoint or traffic evidence to identify the requesting host and contain the activity
• Use Advanced WildFire so unknown files can be analyzed and verdicts can inform protection
• Use risk-aware URL category policy and monitor outcomes before making broad exceptions
• Use the WildFire verdict and related indicators to block or prevent subsequent delivery and investigate affected hosts
• Maintain required content, software compatibility, licensing, and service connectivity and review service health

Correct answer: B

Explanation

1. DNS detections can reveal compromised hosts or command-and-control attempts and should be correlated with the source endpoint. This can be valid in another context, but it does not directly satisfy the stated requirement(s): analyze suspicious files that are not known good or known malicious.
2. WildFire provides cloud-delivered malware analysis and verdicts that complement local signature-based controls. This directly satisfies one of the stated requirement(s).
3. Category-based control allows precise handling of risky web destinations while preserving normal business browsing. This can be valid in another context, but it does not directly satisfy the stated requirement(s): analyze suspicious files that are not known good or known malicious.
4. Cloud analysis should feed prevention and investigation so the same malicious artifact is not repeatedly allowed. This can be valid in another context, but it does not directly satisfy the stated requirement(s): analyze suspicious files that are not known good or known malicious.
5. Cloud-delivered security depends on current content and working connectivity to the relevant Palo Alto Networks services. This can be valid in another context, but it does not directly satisfy the stated requirement(s): analyze suspicious files that are not known good or known malicious.

Question 20

A security review at Trey Research identifies a gap. The team wants to layer prevention for an allowed web application. Which action should it take?

• Use DNS Security logs and related endpoint or traffic evidence to identify the requesting host and contain the activity
• Use Advanced Threat Prevention or the applicable threat-prevention profiles on allowed sessions
• Use Advanced WildFire so unknown files can be analyzed and verdicts can inform protection
• Maintain required content, software compatibility, licensing, and service connectivity and review service health
• Combine application policy with URL filtering, threat prevention, WildFire, DNS security, and logging as applicable to the flow

Correct answer: E

Explanation

1. DNS detections can reveal compromised hosts or command-and-control attempts and should be correlated with the source endpoint. This can be valid in another context, but it does not directly satisfy the stated requirement(s): layer prevention for an allowed web application.
2. Threat Prevention analyzes traffic for vulnerability exploits and other malicious patterns and can take configured prevention actions. This can be valid in another context, but it does not directly satisfy the stated requirement(s): layer prevention for an allowed web application.
3. WildFire provides cloud-delivered malware analysis and verdicts that complement local signature-based controls. This can be valid in another context, but it does not directly satisfy the stated requirement(s): layer prevention for an allowed web application.
4. Cloud-delivered security depends on current content and working connectivity to the relevant Palo Alto Networks services. This can be valid in another context, but it does not directly satisfy the stated requirement(s): layer prevention for an allowed web application.
