ITPEC IP October 2022 Question 19
ITPEC IP October 2022 — Question 19 of 100
Keeping an original copy and comparing it with the modified file identifies exactly which contents changed. A record-by-record or byte-level comparison can show additions, deletions, and altered fields, whereas metadata alone cannot reveal the actual modifications.
Answer (b)
Why not others:
- file size and modification date show that a change may have occurred, not what changed
- record count misses edits that do not add or remove records
- sorting by key changes order but does not preserve a before-state for comparison
Key rule: To identify content differences, retain a baseline or version and compare it with the later version.
