In Kubernetes, the data inside a Secret is typically stored in what form?

• A. Base64-encoded
• B. Encrypted with AES-256
• C. Plain text
• D. Compressed with gzip

Answer: (A)

Base64-encoded data. Kubernetes stores Secret values as base64-encoded strings in etcd. The Secret’s data field is a map where each value is encoded, and you can provide plaintext with stringData—the API server encodes it to base64 when persisting. Remember, base64 is encoding, not encryption, so if you need secrecy you must enable encryption at rest or use a KMS provider.
