In the case where a static route is not added, what could be the reason related to interface status?

In network configuration, a static route relies on the availability and status of interfaces. When an interface is disabled, it cannot forward any traffic or establish routes, which directly affects the ability to add or utilize static routes. An interface may be disabled for various reasons, such as administrative actions, configuration errors, or physical issues. In this case, if the interface is disabled, it does not participate in routing decisions, meaning that static routes would not be operational or recognized, leading to connectivity issues.

Other factors might influence the ability to add a static route, such as an interface being busy or undergoing maintenance, but these do not necessarily prevent the configuration of static routes like a disabled interface does. If an interface is busy, it may still be functional and could theoretically allow for routing modifications, while maintenance might involve temporary service interruptions without rendering the interface completely inoperable. The notion that the interface is configured correctly would imply that it is operational, which does not align with the question regarding the lack of a static route being added.
