Palo Alto Networks PCNSE Exam Practice Questions (P. 2)

GPT-4o - Answer

The correct approach to scheduling an Applications and Threats dynamic update while introducing a delay in the installation is by setting up a threshold that dictates how long the system should wait before proceeding with the installation after the update has been downloaded. This allows an administrator to configure an automatic delay, ensuring that updates are not immediately applied, providing a window to address any potential compatibility or security concerns. This setup can be crucial for maintaining stability and security in sensitive or high-stakes environments.

GPT-4o - Answer

The correct answer is indeed A. Initially, traffic to https://www.microsoft.com is identified as SSL due to its encrypted nature on port 443. Once decrypted by the firewall's SSL decryption feature, the application is recognized as web-browsing while still using port 443. This phenomenon is referred to as application shift, where post-decryption, the true nature of the application is revealed without altering the service port. Thus, decrypted packets from the website appear as "web-browsing" and continue to use port 443 in the Traffic log. This detailed explanation aligns perfectly with how Palo Alto Networks products handle encrypted traffic.

To properly control access to sensitive internal applications, configuring an Authentication policy on PAN-OS is essential. This policy mandates users to authenticate themselves whenever they try to access specified services or applications. By setting up rules within this policy, administrators can specify the required authentication method, such as passwords, biometric verification, or multi-factor authentication, effectively safeguarding sensitive data by ensuring that only authorized users gain access.
