DP-300 Plan and implement data platform resources Practice Question
A healthcare company is required to encrypt all patient data at rest and in transit. They are deploying Azure SQL Database. Which combination of features should they implement to meet this requirement?
⚠ Common exam trap
Many candidates confuse Always Encrypted with a complete encryption solution for both at rest and in transit, but it only encrypts specific columns and does not encrypt the entire transport channel, leaving the connection vulnerable without TLS.
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
✓
Transparent data encryption (TDE) and TLS 1.2
Transparent Data Encryption (TDE) encrypts data at rest by performing real-time I/O encryption and decryption of the database, data files, and transaction logs, while TLS 1.2 encrypts data in transit between the client and Azure SQL Database. Together, they satisfy the requirement to encrypt all patient data both at rest and in transit.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Transparent data encryption (TDE) and TLS 1.2
Why this is correct
TDE encrypts data at rest, TLS encrypts data in transit.
- ✗
Dynamic data masking and row-level security
Why it's wrong here
Neither provides encryption.
- ✗
Azure Active Directory authentication and firewall rules
Why it's wrong here
Authentication and firewall do not encrypt data.
- ✗
Always Encrypted and transparent data encryption (TDE)
Why it's wrong here
Always Encrypted is for specific columns, not all data at rest.
