DVA-C02 Deployment Practice Question

This DVA-C02 practice question tests your understanding of deployment. 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 developer is deploying a web application on AWS Elastic Beanstalk. The application uses a relational database and requires a custom environment variable for the database connection string. The developer has created an Elastic Beanstalk environment and wants to set the environment variable securely without exposing it in the source code or configuration files. The developer also wants to ensure that the environment variable is available to the application instances at deployment time. What is the BEST way to achieve this?

Clue words in this question

Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.

A
Set the environment variable using the Elastic Beanstalk console or CLI by configuring environment properties.
Elastic Beanstalk environment properties are secure and automatically available to instances.
B
Store the connection string in AWS Systems Manager Parameter Store and retrieve it from the application code at runtime.
Why wrong: While secure, this adds unnecessary complexity for a simple environment variable; Elastic Beanstalk environment properties are more straightforward.
C
Hardcode the connection string in the application code and commit it to the source repository.
Why wrong: Hardcoding secrets is insecure.
D
Store the connection string in a file named 'env.txt' in the application source bundle and read it at application startup.
Why wrong: Storing secrets in source code or bundles is insecure.

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 environment variable using the Elastic Beanstalk console or CLI by configuring environment properties.

Option B is correct because Elastic Beanstalk allows setting environment properties in the environment configuration, which are securely passed to the instances. Option A is incorrect because storing the connection string in a plain text file is insecure. Option C is incorrect because hardcoding the value in the application code is not secure and not a best practice. Option D is incorrect because although AWS Systems Manager Parameter Store can store the value, the application would need to retrieve it at runtime, adding complexity; Elastic Beanstalk environment properties are simpler and automatically injected.

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 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.
