Selected Answer: D
Kubernetes Secrets store sensitive information such as passwords, OAuth tokens, and SSH keys. The data stored in Secrets is base64 encoded by default. However, it's important to note that base64 encoding is not encryption—it's a reversible encoding scheme. While base64 encoding provides a basic level of obfuscation, it does not provide strong security against unauthorized access.

In Kubernetes, Secrets are stored as base64-encoded strings within etcd, the key-value store used by Kubernetes. Base64 encoding is a method of encoding binary data into ASCII characters, but it is not a form of encryption. Therefore, while base64 encoding obfuscates the data, it does not provide encryption or protection against unauthorized access. It's essential to use additional measures like RBAC (Role-Based Access Control) or encryption mechanisms like encryption at rest to enhance the security of Secrets in Kubernetes.
