SOA-C02 Reliability and Business Continuity Practice Question

This SOA-C02 practice question tests your understanding of reliability and business continuity. 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 wants to ensure that its EC2 instances receive patches automatically to maintain security compliance. Which AWS service can be used to automate patch management?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

AWS Systems Manager

AWS Systems Manager Patch Manager automates the process of patching managed EC2 instances and on-premises servers. It uses patch baselines to define approved patches and can schedule patching across maintenance windows, ensuring security compliance without manual intervention.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse AWS Config's compliance evaluation with actual remediation actions, but Config only detects drift and can trigger automation via Systems Manager Automation documents—it does not directly patch instances.

Detailed technical explanation

How to think about this question

Patch Manager integrates with SSM Agent on EC2 instances to execute patching commands via the Run Command capability. It supports both Windows Server Update Services (WSUS) and Linux package managers (e.g., yum, apt) and can generate compliance reports showing patch status per instance. A real-world scenario is using Patch Manager with a maintenance window to apply critical security patches to a fleet of hundreds of instances during a predefined weekly downtime window.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
