Why does the defaultbase64 encodingthat Kubernetes applies to the contents of Secret resources provide inadequate protection?

Base64 encoding is vulnerable to brute-force attacks.

Base64 encoding relies on a shared key which can be easily compromised.

Base64 encoding does not encrypt the contents of the Secret, only obfuscates it.

Base64 encoding is not supported by all Secret Stores.

Which of the following statements about kubelet security is correct?

Kubelet runs as a privileged container by default.

Kubelet does not have any built-in security features.

Kubelet supports TLS authentication and encryption for secure communication with the API server.

Kubelet requires root access to interact with the host system.

NEW QUESTION 51

Denial of Service

Data exfiltration

Increased attack surface

Unauthorized access to external resources

NEW QUESTION 52
