ITPEC IP April 2026 Question 17
ITPEC IP April 2026 — Question 17 of 100
Keep a copy and compare it with the modified file — identifying the modified contents requires both the before and after data.
A byte-by-byte or record-by-record comparison between the saved original and the current file reveals exactly which fields or records changed. Metadata can indicate that some change occurred, but it cannot reconstruct the changed content.
Answer (b)
Why not others:
- (a) file size and modification date may show that a file changed, but not what content changed; an edit can even preserve the same size
- (c) the record count detects additions or deletions only, not modifications within an existing record
- (d) sorting by a key changes organization and helps searching, but provides no original value for comparison
Key rule: To identify content differences, retain a baseline version and compare the baseline with the current version.
