AWS Certified Solutions Architect – Professional — Question 275

DynamoDB uses only as a transport protocol, not as a storage format.

Answer options

• A. WDDX
• B. XML
• C. SGML
• D. JSON

Correct answer: D

Explanation

DynamoDB uses JSON as a serialization and transport protocol to send and receive data via its API, but it does not store the data in JSON format on disk. Instead, it uses an optimized internal binary format for storage. Other markup languages like XML, SGML, and WDDX are not used by DynamoDB for this purpose.
