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 for configuration management. They want to migrate to AWS Systems Manager for patching and automation. They have a fleet of EC2 instances running Amazon Linux 2. Which Systems Manager capability should they use to automate patching?
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 A is correct: Systems Manager Patch Manager is designed for patching. Option B (Run Command) can run scripts but not schedule patching natively. Option C (State Manager) can enforce state but not specifically patching. Option D (Maintenance Windows) is a scheduling mechanism, but used with Patch Manager.
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.
✓
Patch Manager
Why this is correct
Patch Manager automates the process of patching managed instances with security updates.
Related concept
Static NAT maps one inside address to one outside address.
✗
State Manager
Why it's wrong here
State Manager enforces a desired state configuration; patching can be one component but not primary.
✗
Run Command
Why it's wrong here
Run Command can be used to run scripts for patching but is not a dedicated patching solution.
✗
Maintenance Windows
Why it's wrong here
Maintenance Windows schedule the execution of actions, but the actual patching is done by Patch Manager.
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.
Trap categories for this question
Command / output trap
Run Command can be used to run scripts for patching but is not a dedicated patching solution.
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 DVA-C02 NAT questions on configuration and troubleshooting.
