CompTIA A+ 220-1102 (V14) Practice Question

The most likely reason for a service set to "Automatic" failing to start is that another service it depends on has also failed to start. Windows enforces these dependencies, so if a prerequisite service does not launch, the dependent service will also be prevented from starting. While an 'Automatic (Delayed Start)' service also starts automatically, it does so after a short delay post-boot, which would not be a failure. Most services start with the system regardless of user login status. A disabled Windows Event Log service would hinder troubleshooting by not recording the error, but it would not typically be the root cause of another service's failure unless it is a specific dependency.
