Explanation: Decryption can be resource-intensive, and in scenarios where the firewall is nearing its resource limits, optimizing decryption practices is crucial. One way to do this is by choosing more efficient encryption algorithms that require less computational power.
C. Use ECDSA instead of RSA for traffic that isn't sensitive or high-priority:
Elliptic Curve Digital Signature Algorithm (ECDSA) is known for requiring smaller key sizes compared to RSA for a comparable level of security. This translates to less computational overhead during the encryption and decryption processes.
By using ECDSA for traffic that isn't sensitive or high-priority, the administrator can reduce the processing load associated with decryption on the firewall. This is particularly beneficial in scenarios where resource optimization is necessary.
It's important to note that this approach does not compromise the security of encrypted traffic. Instead, it offers a more resource-efficient way to manage decryption, thus helping to maintain firewall performance even when system resources are under significant demand.
By judiciously applying this strategy, administrators can manage the decryption workload on the firewall, ensuring continued protection and inspection of encrypted traffic without overburdening the firewall's resources.

Explanation: The correct packet-flow sequence is C. PBF > Static route > Security policy enforcement. This sequence describes the order of operations that the firewall performs when processing a packet. PBF stands for Policy-Based Forwarding, which is a feature that allows the firewall to override the routing table and forward traffic based on the source and destination addresses, application, user, or service. PBF is evaluated before the static route lookup, which is the default method of forwarding traffic based on the destination address and the longest prefix match. Security policy enforcement is the stage where the firewall applies the security policy rules to allow or block traffic based on various criteria, such as zone, address, port, user, application, etc.

Explanation: >Threat logs, create a log forwarding profile to define how you want the firewall or Panorama to handle logs. >Configure an HTTP server profile to forward logs to a remote User-ID agent. > Select the log forwarding profile you created then select this server profile as the HTTP server profile https://docs.paloaltonetworks.com/pan-os/11- 0/pan-os-admin/policy/use-auto-tagging-to-automate-security-actions

Explanation: https://live.paloaltonetworks.com/t5/panorama-discussions/panorama-force-template-valueoption/ td-p/496620 "- Force Template Value will as the name suggest remove any local configuratio and apply the value define the panorama template. But this is valid only for overlapping configuration" "You need to be careful, what is actually defined in the template. For example - if you decide to enable HA in the template, but after that you decide to not push it with template and just disable it again (remove the check from the "Enable HA" checkbox). This still will be part of the template, because now your template is explicitely defining HA disabled. If you made a change in the template, and later decide that you don't want to control this setting with template, you need to revert the config by clicking the green bar next to the changed value"

Explanation: The CLI command "show system state filter-pretty sys.sl.p8.phy" is used to display detailed physical layer information, which would include the physical media connected to a specific interface such as ethernet1/8. This command is designed to filter the output to show relevant physical layer information for the specified interface. For more information on Palo Alto Networks CLI commands and their outputs, refer to the "PAN-OS® CLI Reference Guide".

Explanation: SSL/TLS profile is only the TLS versions, not ciphers. Decryption Profile is for SSL Inbound and Forward Proxy applications, not mgmt of the PANW Firewall. There's also KB articles to strengthen SSH, but I couldn't find any for HTTPS, on the mgmt interface:
