What command is used to display the expectations of a session helper?

The command used to display the expectations of a session helper is indeed "diagnose sys session list expectation." This command allows administrators to see detailed information about the session helper's configured expectations, including how specific types of traffic are managed within the firewall's session handling mechanism.

When executed, it provides a clear overview of the expectations set for various session types and protocols, which is crucial for troubleshooting and optimizing firewall performance. This visibility into session expectations aids in understanding how the firewall is interpreting and managing different network sessions and can help in fine-tuning security policies based on the observed session behaviors.

Other choices do not represent valid commands for retrieving session helper expectations or do not exist in the command structure of the firewall. Being familiar with command structures and their specific syntaxes is essential for effective firewall management, making this command particularly useful for any network security professional.
