A company needs to ensure that data stored in Amazon RDS is encrypted at rest. Which action should the data engineer take?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a new RDS instance with encryption enabled using AWS KMS.
Option D is correct because encryption at rest for RDS is enabled at instance creation time by enabling encryption with KMS. Option A is wrong because encryption is not automatic; it must be enabled. Option B is wrong because encrypting the EBS volumes is not sufficient for RDS; the database must be encrypted. Option C is wrong because encryption in transit is different from at rest.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable encryption at rest by modifying the existing RDS instance.
Why it's wrong here
Encryption at rest cannot be enabled on an existing RDS instance; it must be enabled at creation.
✗
Encrypt the underlying EBS volumes using AWS KMS.
Why it's wrong here
RDS manages the underlying storage; encrypting EBS volumes is not supported for RDS.
✓
Create a new RDS instance with encryption enabled using AWS KMS.
Why this is correct
Encryption at rest must be enabled at launch time for RDS.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
