DBS-C01 Database Security Practice Question

This DBS-C01 practice question tests your understanding of database security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A company is using Amazon RDS for PostgreSQL and wants to implement encryption in transit for all client connections. The security team has identified that some connections are not using SSL. Which TWO actions should the company take to enforce SSL for all connections?

A
Set the 'rds.force_ssl' parameter to '1' in the DB parameter group.
This parameter forces the PostgreSQL server to reject non-SSL connections.
B
Install the RDS CA certificate on all client machines.
Why wrong: This enables trust but does not enforce SSL; the client could still connect without SSL.
C
Create a new SSL certificate and associate it with the RDS instance.
Why wrong: RDS uses a default SSL certificate; creating a new one is not required.
D
Configure the application connection string to use 'sslmode=require'.
Why wrong: This is a client-side setting; it does not enforce server-side.
E
Modify the pg_hba.conf file to require SSL for all users by setting 'hostssl' entries.
pg_hba.conf controls authentication; requiring SSL for all hosts 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.

The correct actions to enforce SSL for all connections are A and E. Option A: Setting 'rds.force_ssl' to '1' in the DB parameter group forces the RDS PostgreSQL instance to require SSL for all incoming connections at the server level. Option E: Modifying the 'pg_hba.conf' file to require SSL for all users via 'hostssl' entries ensures that only SSL connections are allowed, complementing the server-side enforcement. Option C is incorrect because associating a custom SSL certificate is not required for enforcing SSL; AWS RDS provides a valid certificate. Option B is a client-side configuration that does not enforce server-side SSL. Option D is client-side and not a server-side enforcement action. Options A and E together provide robust server-side enforcement.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

What to study next
