Why each option
The `show | compare rollback 1` command displays the differences between the current candidate configuration and the configuration that was active immediately before the last commit.
The command `show | compare rollback 1` does not compare two candidate configurations; it compares the current candidate with a previously committed configuration.
The command `show | compare` (without `rollback`) compares the current active configuration with the current candidate configuration, not `show | compare rollback 1`.
The command compares the current *candidate* configuration with a previous active configuration, not the current active configuration with a previous active configuration.
The `show | compare rollback <number>` command is used to compare the current uncommitted candidate configuration with a previously committed configuration. `rollback 1` specifically refers to the configuration that was active one commit ago, which is effectively a stored or 'archived' version of a past configuration.
