200-201 Is developing a new cloud-based application Practice Question
An organization is developing a new cloud-based application. The security policy requires that all data be encrypted in transit and at rest. Which combination of controls meets this requirement?
⚠ Common exam trap
200-201 often tests the misconception that a single control (VPN, HTTPS, or TDE) satisfies both in-transit and at-rest requirements — candidates must recognize that two distinct controls are needed.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use HTTPS and encrypt the database with TDE
The requirement is encryption both in transit and at rest. HTTPS (TLS) encrypts data in transit between clients and the application, while Transparent Data Encryption (TDE) encrypts the database files at rest. Using both together satisfies the dual requirement, making option D the only complete answer.
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 a VPN for all connections
Why it's wrong here
VPN encrypts data in transit but not at rest.
- ✗
Encrypt the database using Transparent Data Encryption (TDE)
Why it's wrong here
TDE encrypts database files at rest but does nothing for data moving across the network. TDE is the right control when the requirement is limited to protecting stored database contents, not the in-transit half of this policy.
- ✗
Use HTTPS for all communication
Why it's wrong here
HTTPS encrypts data in transit only; it provides no encryption for data stored at rest in databases, buckets or volumes. HTTPS is the correct control when the requirement covers only transport security, not the at-rest half of this policy.
- ✓
Use HTTPS and encrypt the database with TDE
Why this is correct
HTTPS enforces TLS between client and server, covering data in transit. Transparent Data Encryption encrypts database files and backups at rest without application changes. Together they satisfy both halves of the policy's encryption mandate across the application's communication and storage layers.
