SOA-C02 Deployment, Provisioning, and Automation Practice Question

This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. 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 uses AWS Elastic Beanstalk to deploy a web application. The application uses an Amazon RDS database. The company wants to ensure that database credentials are not hard-coded in the application code. Which approach should be used?

A
Pass the credentials via EC2 user data when the instance launches.
Why wrong: User data is not encrypted and can be viewed by anyone with access to the instance metadata.
B
Store the credentials in a configuration file in the application source code.
Why wrong: Storing credentials in source code is insecure.
C
Use Elastic Beanstalk environment properties to pass the credentials, referencing them from AWS Secrets Manager.
Secrets Manager securely stores and rotates credentials; environment properties can reference them.
D
Store the credentials in an S3 bucket and retrieve them at runtime.
Why wrong: While possible, it's not the recommended approach; S3 bucket access must be managed.

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 Elastic Beanstalk environment properties to pass the credentials, referencing them from AWS Secrets Manager.

The correct answer is C. Elastic Beanstalk environment properties can reference values from AWS Secrets Manager, allowing the application to retrieve database credentials securely without hard-coding them. Option A is wrong because EC2 user data is not encrypted and can be viewed in the console. Option B is wrong because storing credentials in a configuration file within the source code exposes them in version control and is insecure. Option D is wrong because while S3 can store credentials, it requires additional access management and is not the recommended approach for Elastic Beanstalk; Secrets Manager or Systems Manager Parameter Store is preferred.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Quick reference

AWS S3 Storage Class Comparison

Storage Class	Min Duration	Retrieval	Use Case
S3 Standard	None	Immediate	Frequently accessed data
S3 Standard-IA	30 days	Immediate	Infrequent access, rapid retrieval
S3 One Zone-IA	30 days	Immediate	Non-critical infrequent data
S3 Intelligent-Tiering	None	Immediate–hours	Unknown or changing access patterns
S3 Glacier Instant	90 days	Milliseconds	Archive with instant retrieval
S3 Glacier Flexible	90 days	Minutes–hours	Archive, flexible retrieval
S3 Glacier Deep Archive	180 days	Hours	Long-term compliance archive
