Question 1 of 3 · BTL1 · Phishing and security operations
Answer and explanation
Best answer: Integrity is unverified and the mismatch needs investigation
The mismatch means this copy has not passed integrity verification. Preserve the acquisition record and investigate the transfer or obtain a verified copy before relying on it.
Why the other choices fit less well
Names and sizes can remain unchanged when bytes differ. Silently replacing the acquisition hash conceals the discrepancy and undermines the evidence record.
