220-1202 Practice Question: A technician is preparing to deploy a security…
A technician is preparing to deploy a security patch to 50 workstations. The change request has been approved, and the patch has been tested on a pilot group. During the deployment, five workstations fail to install the patch. What should the technician do next according to change management best practices?
⚠ Common exam trap
CompTIA often tests the misconception that troubleshooting can be deferred or that a new change request is required for each failure, when in fact the approved change request already covers rollback procedures for failed deployments.

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
✓
Halt the deployment and execute the rollback plan for the failed workstations
According to change management best practices, when a deployment encounters failures, the immediate priority is to halt the deployment to prevent further issues and then execute the rollback plan to restore the failed workstations to their previous known-good state. This ensures stability and minimizes disruption, as the rollback plan was already defined and approved as part of the change request. Continuing or forcing the patch could lead to system instability or security vulnerabilities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Continue deploying to the remaining workstations and troubleshoot the failures later
Why it's wrong here
Continuing deployment despite initial failures is a critical error in change management and incident response. This approach risks propagating a faulty patch across the entire environment, potentially causing widespread system instability, data corruption, or introducing new security vulnerabilities that are far more difficult and costly to remediate. It disregards early warning signs and violates the principle of minimizing the blast radius of a problem.
- ✓
Halt the deployment and execute the rollback plan for the failed workstations
Why this is correct
Halting the deployment and executing the pre-defined rollback plan for affected workstations is the correct and most responsible course of action. This immediately mitigates further risk by preventing additional systems from being compromised and restores failed systems to a known stable state. It adheres to established change management protocols, allowing for proper investigation of the failure cause without compounding the problem.
- ✗
Force the patch to install using administrative tools
Why it's wrong here
Forcing a patch installation using administrative tools is highly ill-advised and bypasses crucial testing and validation processes designed to ensure compatibility and stability. This action can lead to unpredictable system behavior, render operating systems unbootable, or introduce severe security vulnerabilities by overriding dependency checks or compatibility safeguards. It demonstrates a disregard for proper change control and problem-solving methodologies, potentially exacerbating the initial issue.
- ✗
Submit a new change request for the failed workstations
Why it's wrong here
Submitting a new change request solely for the failed workstations is an inefficient and unnecessary bureaucratic step that delays immediate resolution. A well-designed change management plan should already include contingency procedures, such as a rollback, to address deployment failures without requiring a completely new approval cycle. This approach fails to leverage existing incident response and recovery protocols, prolonging system downtime and risk.
