Global Variable files are used to share data between jobs. Which statement best describes their purpose?

• A. Global Variable files are temporary and limited to a single job.
• B. Global Variable files are available to all jobs so data stored from one job can be used by another.
• C. Global Variable files are automatically deleted after each run.
• D. Global Variable files are only accessible by system administrators.

Answer: (B)

Global Variable files provide a shared, persistent data store that all jobs can access. They’re not limited to a single job; once a value is written, any other job with the right permissions can read it, enabling data produced by one job to be used by another. They aren’t automatically deleted after a run, and they aren’t restricted to system administrators. This makes them ideal for inter-job communication and coordination, such as storing a computed setting or a status flag that a later job needs to read to proceed. If you want data to stay private to one job, keep it in local variables or pass it directly.
