Tab entry failure during initialization occurs during which phase?

Tab entry failure during initialization occurs during which phase?

• A. Initialization
• B. Operation
• C. Testing
• D. Maintenance

Answer: (A)

Tab entry issues tied to startup are a setup-time problem. During initialization, the system reads and validates all configuration data, builds necessary tables, and establishes the initial state. If a tab entry is missing, corrupted, or inaccessible, the initialization process cannot complete, so the failure surfaces right at startup. In later phases, the system is already up and running, so you’d see different symptoms, or errors would be tied to runtime use rather than the initial setup. That’s why this kind of failure is associated with the initialization phase.
