The answer is to use AWS Systems Manager Patch Manager to scan and generate a compliance report. This is the most efficient method because Patch Manager is purpose-built to automate the process of scanning managed instances for missing patches and producing a detailed compliance report against a defined patch baseline, directly addressing the security team’s requirement. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your ability to distinguish between Systems Manager capabilities: while State Manager and Inventory collect system data, they do not natively report patch compliance, and AWS Config requires custom rules to achieve the same result. A common trap is confusing Inventory’s general data collection with Patch Manager’s specific scanning functionality. Remember the memory tip: “Patch Manager patches and reports; Inventory just inventories.”
SOA-C02 Deployment, Provisioning, and Automation Practice Question
This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 a fleet of EC2 instances. The Security Team requires that all instances have a specific security patch installed. A SysOps administrator needs to verify compliance across all instances. What is the MOST efficient way to accomplish this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Systems Manager Patch Manager to scan and generate a compliance report.
AWS Systems Manager Patch Manager can scan instances for missing patches and report compliance. State Manager and Inventory collect data but do not specifically report patch compliance. OpsCenter is for operational issues. Config rules can check compliance but require custom rules.
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.
✗
Use AWS Config rules to check for the patch.
Why it's wrong here
Config rules can be used but require custom development; Patch Manager is more efficient.
✗
Use AWS Systems Manager State Manager to enforce the patch.
Why it's wrong here
State Manager enforces configurations but does not provide a compliance report by default.
✗
Use AWS Systems Manager Inventory to collect software inventory.
Why it's wrong here
Inventory collects installed software but does not specifically report patch compliance against a required patch.
✓
Use AWS Systems Manager Patch Manager to scan and generate a compliance report.
Why this is correct
Patch Manager can scan instances and report patch compliance status.
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 SOA-C02 NAT questions on configuration and troubleshooting.
