This scenario highlights common challenges with decrypting encrypted traffic for application layer inspection. Option A is correct because decryption policies must apply to the correct zones and traffic flows; misconfiguration can cause traffic to bypass decryption. Option B is incorrect; App-ID identifies the application regardless of whether it's decrypted or not, although granular enforcement after identification often requires decryption for full Content-ID, Threat Prevention, etc. Option C is correct; the firewall/Prisma Access has limitations on supported SSL/TLS versions, cipher suites, and key exchange methods. If an application uses unsupported parameters, decryption will fail, and depending on the decryption profile's action for 'decryption errors', the session might be allowed without inspection. Option D is correct; applications using mechanisms like certificate pinning or client authentication can break when a decryption proxy intercepts and re-signs the certificate. Exclusions for such applications are often necessary. Option E is incorrect; Security policy rule evaluation happens after App-ID identification and typically after decryption policy evaluation (if decryption is enabled for the matched rule's traffic). Rule order primarily affects which policy is applied to the identified application, not whether decryption happens or fails beforehand.
