220-1102 Practice Question: A change advisory board (CAB) approves a network…
A change advisory board (CAB) approves a network switch replacement, but the technician discovers during implementation that the new switch requires a different firmware version than documented. The change plan does not include a rollback for this scenario. What is the best course of action?
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
✓
Stop the implementation and contact the CAB for a revised change plan.
When an undocumented deviation occurs during a change, the technician should halt the implementation and contact the CAB for guidance. Proceeding without approval risks network instability, and the CAB can provide a revised plan or approve the firmware change.
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 firmware update and document the change afterward.
Why it's wrong here
Proceeding with an unapproved firmware update directly violates established change management policies, bypassing the critical review and risk assessment functions of the Change Advisory Board (CAB). This action introduces significant risk, potentially leading to system instability, security vulnerabilities, or unexpected downtime, all without proper documentation or a tested rollback plan.
- ✓
Stop the implementation and contact the CAB for a revised change plan.
Why this is correct
Halting the implementation and immediately contacting the Change Advisory Board (CAB) is the correct procedure when a deviation from the approved change plan is identified. This ensures that the proposed firmware update undergoes proper review, risk assessment, and formal approval, allowing the CAB to revise the change plan to include the new firmware, testing protocols, and a comprehensive rollback strategy.
- ✗
Use the old switch firmware on the new switch to match the documentation.
Why it's wrong here
Using outdated or potentially incompatible firmware on a new network switch, simply to match existing documentation, introduces significant technical risks. This approach can lead to critical performance issues, system instability, security vulnerabilities due to unpatched exploits, or even hardware damage, while also failing to address the underlying discrepancy in the approved change plan.
- ✗
Implement the switch and create a separate change request for the firmware.
Why it's wrong here
Implementing the network switch with an unapproved firmware version and then creating a separate change request afterward is a risky practice that undermines the entire change management process. This 'implement first, ask for forgiveness later' approach bypasses the essential pre-implementation review and approval by the CAB, potentially deploying an untested or problematic configuration into a live environment without proper authorization or risk mitigation.
