Which statement best describes verification checks?

• A. They look at data to see if it makes sense and is consistent with other data.
• B. They monitor system performance during data entry.
• C. They ensure the data matches a fixed width.
• D. They verify data against an external standard.

Answer: (A)

Verification checks focus on the internal integrity of data. They examine new entries to see if they are sensible and if they align with related information already stored, catching inconsistencies like mismatched dates, impossible combinations, or values that don’t fit with other fields. This internal cross-checks help ensure the data as a whole stays coherent. The other descriptions deal with things outside this internal consistency: monitoring system performance during data entry is about how fast or reliably the system runs, not about the data’s content; ensuring a fixed width is about formatting constraints; and verifying against an external standard is about comparing data to something outside the dataset, which is a different kind of check.
