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 company uses AWS OpsWorks to manage a stack of EC2 instances. After a deployment, the application becomes unresponsive. The engineer suspects that a configuration file was not updated correctly. What is the best way to verify the deployed configuration?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

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
Use AWS Systems Manager Run Command to execute a script that outputs the configuration.
Why wrong: While possible, it is indirect; the direct method is to inspect the OpsWorks configuration files.
B
Check the OpsWorks stack's logs for any JSON syntax errors in the custom JSON.
Why wrong: Syntax errors would cause the deployment to fail, not result in an unresponsive application.
C
SSH into an instance and inspect the configuration files in /var/lib/aws/opsworks.
This location contains the applied configuration, allowing verification of what was actually deployed.
D
Review the application logs in Amazon CloudWatch Logs for configuration errors.
Why wrong: Application logs may show errors but do not directly show the configuration that was deployed.

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

✓

SSH into an instance and inspect the configuration files in /var/lib/aws/opsworks.

Option C is correct because OpsWorks stores its configuration data, including the applied custom JSON and stack settings, in /var/lib/aws/opsworks on each EC2 instance. By SSHing into the instance and inspecting these files, the engineer can directly verify whether the configuration file was updated correctly after deployment, bypassing any application-level logging or abstraction.

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

The trap here is that candidates assume CloudWatch Logs or Systems Manager Run Command are the best tools for configuration verification, overlooking the fact that OpsWorks stores its deployed configuration locally on the instance in a specific directory that can only be inspected directly via SSH.

Trap categories for this question

Command / output trap
Application logs may show errors but do not directly show the configuration that was deployed.

Detailed technical explanation

How to think about this question

Under the hood, OpsWorks uses Chef to apply configuration to instances, and the applied configuration is stored in /var/lib/aws/opsworks, which includes the stack's custom JSON, cookbook attributes, and run list. This directory is the authoritative source for what was actually deployed, as it reflects the final state after Chef runs. In a real-world scenario, if a deployment fails silently due to a Chef error or a misapplied attribute, the configuration in this directory will differ from what was intended, making direct inspection the most reliable verification method.

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.

TExam Day Tips

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.
