CV0-004 Practice Question: A cloud administrator is tasked with ensuring…
A cloud administrator is tasked with ensuring that only encrypted connections are used to transfer files to a cloud storage bucket. Which of the following should the administrator enforce?
⚠ Common exam trap
Many exam-takers confuse SFTP (which is encrypted) with FTP (which is not), and incorrectly assume that enabling SFTP is the correct answer, but the question specifically targets the standard encrypted protocol for cloud storage bucket uploads, which is HTTPS.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Require HTTPS for all uploads.
HTTPS (HTTP over TLS) encrypts data in transit using TLS, ensuring that files uploaded to a cloud storage bucket are protected from eavesdropping and tampering. By requiring HTTPS for all uploads, the administrator enforces encrypted connections as mandated by the security policy, which is a standard practice for cloud storage services like AWS S3 or Azure Blob Storage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use HTTP with a custom header.
Why it's wrong here
A custom HTTP header adds metadata to an unencrypted HTTP request; the payload and credentials still travel in plaintext, so the encrypted-connection requirement is unmet. Custom headers suit routing, caching or authentication signalling, not transport confidentiality, which needs TLS or SSH.
- ✗
Allow FTP but restrict to specific IPs.
Why it's wrong here
FTP transmits credentials and data in plaintext regardless of source-IP filtering; restricting IPs narrows who connects but does not encrypt the connection. IP allowlisting is the correct control when limiting access to trusted networks, not when mandating encryption of file transfers.
- ✓
Require HTTPS for all uploads.
Why this is correct
HTTPS wraps uploads in TLS, encrypting data in transit between the client and the storage endpoint. Enforcing it on the bucket rejects plain HTTP PUT requests, satisfying the requirement that only encrypted connections transfer files.
- ✗
Enable SFTP access to the bucket.
Why it's wrong here
SFTP encrypts transport via SSH, but enabling it does not prevent bucket access over unencrypted FTP or HTTP; the requirement is that only encrypted connections are used, so plaintext paths must be blocked. SFTP would be the right enforcement when the bucket accepts solely SSH-based file transfer.
