DBS-C01 Deployment and Migration Practice Question
A company is deploying a new RDS for MySQL database and needs to ensure that connections are encrypted using TLS. Which parameter should be configured?
⚠ Common exam trap
Test-takers frequently confuse the MySQL native `require_secure_transport` parameter (which is not available in RDS) with the RDS-specific `rds.force_ssl` parameter, or they mistakenly think that setting a TLS version alone enforces encryption.
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
✓
Set the rds.force_ssl parameter to 1 in the DB parameter group.
In Amazon RDS for MySQL, the `rds.force_ssl` parameter must be set to 1 in the DB parameter group to enforce TLS/SSL for all connections. This parameter, when enabled, requires clients to use SSL/TLS encryption when connecting to the database instance, ensuring data in transit is encrypted.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set the ssl_ca parameter to the RDS CA certificate.
Why it's wrong here
ssl_ca specifies the CA, but does not enforce encryption.
- ✗
Set the require_secure_transport parameter to ON.
Why it's wrong here
This parameter is not available in RDS MySQL parameter groups.
- ✗
Set the tls_version parameter to TLSv1.2.
Why it's wrong here
tls_version sets the allowed TLS version, but does not enforce encryption.
- ✓
Set the rds.force_ssl parameter to 1 in the DB parameter group.
Why this is correct
rds.force_ssl=1 enforces that all connections use SSL/TLS.
