Which command allows you to check the syntax of your configuration without activating it?

The command that allows you to check the syntax of your configuration without activating it is "commit check." This command is useful for verifying the configuration changes you have made in the Junos OS before applying them to the active configuration. When you run "commit check," the system assesses the configuration for any syntax errors or issues, allowing you to identify problems without impacting the live network configuration.

Once the command is executed, if there are no errors, you can be confident that the syntax is valid, and you can then proceed to commit the changes without any risk of causing issues due to mistakes in your configuration. This capability is particularly important for network administrators who want to ensure their changes are correct and avoid downtime or operational issues caused by misconfigurations.

Other options, while related to the configuration process, serve different purposes. For instance, "commit confirmed" is used to commit changes with a temporary validation period, which requires a second commit within a specified timeframe to make those changes permanent. "commit validate" allows for checking the validity of configuration changes but differs in usage from "commit check." "show configuration," on the other hand, is used to display the existing configuration but does not validate syntax.
