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.
A company uses AWS Systems Manager to manage patching of EC2 instances. They want to ensure that instances in a specific Auto Scaling group are patched before being allowed to serve traffic. Which THREE steps should be part of the solution?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a new launch configuration with the patched AMI.
Options A, B, and E are correct. Option A ensures instances are patched before use. Option B creates new instances. Option E updates the Auto Scaling group to use the new launch configuration. Option C (CodeDeploy) is not needed for patching. Option D (CloudWatch Events) is optional and not required.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Create a new launch configuration with the patched AMI.
Why this is correct
After patching, create a new AMI and launch configuration.
Related concept
Static NAT maps one inside address to one outside address.
✓
Update the Auto Scaling group to use the new launch configuration.
Why this is correct
New instances will then use the patched AMI.
Related concept
Static NAT maps one inside address to one outside address.
✗
Deploy the patched version using AWS CodeDeploy.
Why it's wrong here
CodeDeploy is for application updates, not OS patching.
✗
Configure Amazon CloudWatch Events to trigger a Lambda function after patching.
Why it's wrong here
This is optional, not a required step.
✓
Use an AWS Systems Manager Maintenance Window to apply patches to instances.
Why this is correct
Maintenance Windows can run patching on a schedule.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DOP-C02 NAT questions on configuration and troubleshooting.
