Full Answer

B.1: Blockchain, 2: DDoS attack, 3: Substantive testing / Audit trail, 4: Anti-Money Laundering (AML) KYC control✓ Correct
Task 1: Blockchain is a distributed, immutable ledger. Task 2: A Distributed Denial of Service (DDoS) attack overwhelms servers with traffic. Task 3: Following a transaction through the system verifies the Audit Trail (substantive testing). Task 4: Requiring ID is a Know Your Customer (KYC) control, a key part of Anti-Money Laundering (AML) regulations.

Common mistakes

Confusing DDoS with Ransomware. Confusing Substantive testing with Compliance testing.
