Which command enables you to verify the changes made to candidate configuration before committing the configuration?

The choice that enables you to verify the changes made to the candidate configuration before committing it is indeed the command that shows the current state of the candidate and compares it against the running configuration. This command helps users understand what specific changes have been made, which is critical to ensure that the intended modifications will not negatively impact the network's operations.

When using this command, you can see an output that clearly indicates what has been added, modified, or deleted in the candidate configuration compared to the current running configuration. This capability is particularly useful in complex environments where multiple changes might be in progress, allowing administrators to review their planned alterations comprehensively.

In contrast, the other commands either do not provide a comparison view or focus on different aspects of configuration management. For instance, a command like "show candidate" might display the candidate configuration but does not compare it to running config, thus not fulfilling the verification goal needed prior to committing changes. Similarly, "verify configuration" is not a standard command in Junos for this purpose, and "compare running" typically provides insights into the running configuration without the context of candidate changes. Hence, the choice that facilitates the precise comparison necessary for validation before applying the candidate configuration stands out as the most appropriate selection.
