In what context is a Global Exception relevant?

• A. Within a single screen
• B. Only during user login
• C. When a handler is absent and searching outer contexts
• D. While initiating the application

Answer: (C)

A Global Exception is relevant in the context where it can provide a fallback solution when a specific error handling mechanism is not in place within a localized or limited scope. When an exception occurs, the system will first look for exception handlers defined in the immediate context, such as a specific screen or module. However, if no handlers are present to manage that exception adequately, the Global Exception handler serves as a broader safety net, handling errors that are not explicitly dealt with elsewhere in the application. This makes option C the most accurate answer, as it captures the essence of the Global Exception's role in searching outer contexts when a more specific handler is absent. It demonstrates how Global Exception helps maintain application stability by capturing unhandled errors at a higher level, preventing crashes and offering a streamlined way to manage unexpected scenarios throughout the application lifecycle. The other contexts, such as a single screen, user login, or application initiation, are too narrow or specific and do not represent the broader purpose of a Global Exception in handling errors not addressed by local exception handling mechanisms.
