SOA-C02 Deployment, Provisioning, and Automation Practice Question
This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. 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 automate patching of EC2 instances. The instances are in an Auto Scaling group. The company wants to ensure that patching does not affect application availability. Which feature should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Maintenance Windows
Option A is correct because Systems Manager Maintenance Windows allow scheduling patching during specific time windows, and can be configured to work with Auto Scaling to maintain availability. Option B is wrong because Run Command is for ad-hoc commands. Option C is wrong because Patch Manager is the service, but Maintenance Windows schedule it. Option D is wrong because State Manager is for configuration, not 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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
State Manager
Why it's wrong here
State Manager is for maintaining configuration, not specifically for patching scheduling.
✓
Maintenance Windows
Why this is correct
Maintenance Windows allow scheduling patching during predefined time windows, minimizing impact.
Related concept
Static NAT maps one inside address to one outside address.
✗
Patch Manager
Why it's wrong here
Patch Manager is the patching service, but it needs to be scheduled with Maintenance Windows.
✗
Run Command
Why it's wrong here
Run Command is for executing commands on demand, not scheduled.
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 is for executing commands on demand, not scheduled.
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
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
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 SOA-C02 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Maintenance Windows — Option A is correct because Systems Manager Maintenance Windows allow scheduling patching during specific time windows, and can be configured to work with Auto Scaling to maintain availability. Option B is wrong because Run Command is for ad-hoc commands. Option C is wrong because Patch Manager is the service, but Maintenance Windows schedule it. Option D is wrong because State Manager is for configuration, not patching.

What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
