220-1202 Documentation and Change Management Practice Question
This 220-1202 practice question tests your understanding of documentation and change management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
During a major software rollout, a technician discovers that the deployment script modifies a registry key that is also used by a legacy application. The change was not included in the original change request. What should the technician do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Stop the deployment and submit a new change request for the registry modification.
Option C is correct because any unapproved change to a system, even if necessary, must follow the change management process. The technician discovered that the deployment script modifies a registry key shared with a legacy application, which was not included in the original change request. Stopping the deployment and submitting a new change request ensures proper review, risk assessment, and approval before altering a shared resource that could impact the legacy application.
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.
✗
Proceed with the deployment since the registry change is necessary for the new software.
Why it's wrong here
Proceeding without approval violates change management and could break the legacy application.
✗
Modify the script to skip the registry change and continue.
Why it's wrong here
Modifying the script without authorization is also a change that needs approval.
✓
Stop the deployment and submit a new change request for the registry modification.
Why this is correct
Stopping and submitting a new request ensures the change is properly reviewed and documented, preventing unintended consequences.
Related concept
Read the scenario before looking for a memorised answer.
✗
Document the registry change after the deployment is complete.
Why it's wrong here
Post-deployment documentation does not mitigate the risk of breaking the legacy application during the rollout.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think a necessary change can be made immediately without approval, confusing 'necessary' with 'authorized,' but CompTIA emphasizes that all changes must follow the change management process regardless of urgency.
Detailed technical explanation
How to think about this question
In Windows environments, registry keys like HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run or application-specific keys under HKLM\Software\YourApp can be shared by multiple applications. A deployment script that modifies such a key without a change request can cause race conditions, configuration conflicts, or application crashes. The change management process (e.g., ITIL) requires a formal Request for Change (RFC) to assess impact, obtain approval, and schedule the change to minimize disruption.
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 practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
