CompTIA Cloud Essentials+ (CLO-002) — Question 57

Which of the following stores transactions in a distributed ledger of which all users have a copy?

Answer options

• A. Big Data
• B. Blockchain
• C. Machine learning
• D. Artificial intelligence

Correct answer: B

Explanation

Blockchain is the correct answer as it is specifically designed to store and share transaction data across a distributed network where every participant has a copy. In contrast, Big Data refers to large volumes of data, Machine learning involves algorithms that learn from data, and Artificial intelligence focuses on simulating human intelligence, none of which inherently involve a distributed ledger system.
