DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. 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.
Which TWO AWS services can be used to automate the configuration of EC2 instances at launch? (Choose two.)
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
✓
EC2 user data
EC2 user data allows you to specify scripts or cloud-init directives that run automatically during the first boot cycle of an EC2 instance. This enables automated software installation, configuration, and post-launch tasks without manual intervention, making it a core tool for instance configuration at launch.
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 often confuse AWS Config (which audits existing configurations) or CloudWatch (which monitors) with services that can actively configure instances at launch, when in fact only user data and infrastructure-as-code tools like CloudFormation can perform that initial automation.
Detailed technical explanation
How to think about this question
EC2 user data is passed to the instance via the instance metadata service at http://169.254.169.254/latest/user-data and is executed by cloud-init, which runs during the first boot. Cloud-init supports multiple formats including shell scripts, cloud-config YAML, and include files, and it can be used to install packages, write files, or run commands. In a real-world scenario, you might combine user data with a base AMI to bootstrap a web server, install agents, or join an Active Directory domain without needing a separate configuration management server.
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.
