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 its EC2 instances at scale. The DevOps team wants to ensure that all instances are patched with the latest security updates. Which Systems Manager capability should they use to automate patching?
Run Command
Why wrong: Run Command is for ad-hoc commands.
Patch Manager
Patch Manager is designed for automated patching.
Automation
Why wrong: Automation can be used for patching but Patch Manager is the dedicated capability.
State Manager
Why wrong: State Manager is for configuration management, not patching.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Patch Manager
Option C is correct because Systems Manager Patch Manager automates the process of patching managed nodes with both security-related and other types of updates. Option A is wrong because State Manager is used to define and maintain consistent configuration, not specifically patching. Option B is wrong because Automation is used for common maintenance and deployment tasks but not specifically for patching. Option D is wrong because Run Command is used to execute scripts or commands remotely, not for automated patching.
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
For each option: why learners choose it and why it is or isn't the right answer here.
Run Command
Why it's wrong here
Run Command is for ad-hoc commands.
Patch Manager
Why this is correct
Patch Manager is designed for automated patching.
Related concept
Static NAT maps one inside address to one outside address.
Automation
Why it's wrong here
Automation can be used for patching but Patch Manager is the dedicated capability.
State Manager
Why it's wrong here
State Manager is for configuration management, not patching.
Common exam traps
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.
Trap categories for this question
Command / output trap
Run Command is for ad-hoc commands.
Detailed technical explanation
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.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
What to study next
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.
