Sample Questions

Question 1

A team needs to encrypt 10 TB of data uploaded to S3. The most efficient approach is:

A. Encrypt the entire 10 TB with a single asymmetric RSA-4096 key for maximum security across the workload

B. Encrypt byte twice with two different symmetric keys for defense-in-depth across the data set

C. Use envelope encryption: generate per-object data keys (DEKs) encrypted by a KMS master key (KEK)

D. Encrypt each chunk with a unique RSA-2048 key and store the keys in a separate text file alongside the data

✓ Correct Answer: C

Envelope encryption is the standard pattern at scale: per-object DEKs (symmetric, fast) wrapped by a KMS KEK. A is impractical (RSA is too slow for bulk). B is wasteful. D leaks key material adjacent to data.

Question 2

A TLS handshake fails because the client says the server certificate is "not trusted". The most likely cause is:

A. The server certificate was signed by a CA that is not in the client's trust store, or the cert is self-signed

B. The server uses TLS 1.3 and the client has TLS 1.3 disabled by an enterprise policy on the endpoint

C. The server certificate expired more than 5 years ago and most modern browsers refuse expired certs entirely

D. The server hostname appears in the certificate's Subject Alternative Name but the client also requires CN match

✓ Correct Answer: A

The most common cause is an untrusted CA (private CA without the cert installed, or self-signed). Other causes (expired, hostname mismatch) usually produce more specific error messages. A is the broadest most-likely cause. B, C, and D are more specific scenarios.
