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 Patch Manager to automate patching of Amazon EC2 instances. The SysOps administrator needs to configure a maintenance window that will patch instances on the second Tuesday of every month at 2:00 AM. The administrator wants to ensure that patches are automatically applied but reboots are only performed if required. Which combination of configurations should the administrator use?

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

✓

Create a maintenance window with a cron schedule of cron(0 2 ? * TUE#2 *) and use an AWS-RunPatchBaseline document with operation 'Install' and reboot option 'RebootIfNeeded'.

Option A is correct because it uses the cron expression `cron(0 2 ? * TUE#2 *)` to schedule the maintenance window for the second Tuesday of every month at 2:00 AM, and the `AWS-RunPatchBaseline` document with operation `Install` and reboot option `RebootIfNeeded` ensures patches are applied automatically and reboots only occur when required by the patch installation.

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

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    Create a maintenance window with a cron schedule of cron(0 2 ? * TUE#2 *) and use an AWS-RunPatchBaseline document with operation 'Install' and reboot option 'RebootIfNeeded'.

    Why this is correct

    This schedule correctly specifies the second Tuesday of each month at 2 AM. The document and operation apply patches, and RebootIfNeeded only reboots if necessary.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Create a maintenance window with a rate schedule of 30 days and use an AWS-ApplyPatchBaseline document with operation 'Scan' and reboot option 'RebootIfNeeded'.

    Why it's wrong here

    A rate schedule cannot specify a particular day of the week. The operation 'Scan' only checks for missing patches without installing them.

  • ✗

    Create a maintenance window with a cron schedule of cron(0 2 14 * ? *) and use an AWS-RunPatchBaseline document with operation 'Install' and reboot option 'RebootIfNeeded'.

    Why it's wrong here

    This cron schedule triggers on the 14th day of every month, not the second Tuesday.

  • ✗

    Create a maintenance window with a cron schedule of cron(0 2 2 * 2 *) and use an AWS-InstallPatchBaseline document with operation 'Install' and reboot option 'NoReboot'.

    Why it's wrong here

    The cron expression is invalid; the correct format uses ? for day-of-week and * for month. Also, AWS-InstallPatchBaseline is not a valid SSM document.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse the cron syntax for 'second Tuesday' with simpler day-of-month or day-of-week expressions, or mistakenly use invalid SSM document names like `AWS-ApplyPatchBaseline` or `AWS-InstallPatchBaseline`, which do not exist in AWS Systems Manager.

Detailed technical explanation

How to think about this question

The `AWS-RunPatchBaseline` document uses the `Install` operation to apply patches from the configured patch baseline, and the `RebootIfNeeded` option checks the patch installation exit code to determine if a reboot is required, automatically rebooting only when necessary. The cron expression `TUE#2` is a special syntax in AWS Maintenance Windows that specifically targets the second occurrence of Tuesday in a month, which is distinct from standard Unix cron and is validated by the AWS scheduler. In real-world scenarios, using `RebootIfNeeded` is critical for critical workloads where unnecessary reboots cause downtime, but the patch baseline must be configured with the appropriate approval rules to avoid missing required patches.

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.
