On a Palo Alto Networks firewall, changes made to an interface management profile take effect in the running configuration only after a commit operation is performed.

### Why this is right The lab's final interface-management step explicitly instructs students to commit the changes. A commit applies the candidate configuration to the firewall's active configuration. ### The concept Configuration entered in the management interface does not necessarily take effect immediately. The lab places the commit before host ping tests so that the configured interface permissions are active when students test them. ### Terms - **Commit**: Applying pending firewall configuration changes so they become active. ### Remember After changing the firewall configuration, commit before testing its effect.
