PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
A project manager is working on a project to upgrade the company's email system from an on-premises Exchange server to Microsoft 365. The project has completed the planning phase and is now in execution. During a weekly status meeting, the lead engineer reports that the initial migration batch of 100 users experienced significant delays due to unexpected compatibility issues with custom email add-ins used by the finance department. Additionally, the migration tool failed to synchronize some mailbox items, causing data loss for three users. The project timeline is tight, and the sponsor is concerned about meeting the go-live date in four weeks. There are still 900 users to migrate. The project manager needs to take action. Which of the following is the BEST course of action?
⚠ Common exam trap
A common mix-up: candidates choose Option D (buy a new tool) because it sounds proactive, but the PMBOK framework requires first analyzing the risk and engaging stakeholders before committing additional budget, making Option C the correct process-driven answer.

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
✓
Convene a meeting with the finance department to understand the criticality of the add-ins, and update the risk register with the new findings, then adjust the project schedule accordingly.
The best course of action because it directly addresses the root cause—the custom email add-ins—by engaging the finance department to assess criticality, then formally updating the risk register and adjusting the schedule. This aligns with the PMBOK risk management process and allows the project to proceed with informed decisions rather than ignoring the issue or overreacting. The technical context is that custom Outlook add-ins often rely on on-premises Exchange Web Services (EWS) or MAPI over HTTP, which may not be fully compatible with Microsoft 365's REST-based APIs, causing migration failures.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Instruct the team to proceed with the migration of the remaining users using the same tool to avoid further delays.
Why it's wrong here
Repeating the same process with the same tool reproduces the add-in compatibility failures and mailbox synchronisation data loss across the remaining 900 users. Proceeding unchanged is appropriate only when issues are resolved and metrics confirm readiness. The project manager must first correct the defects and re-test a pilot batch.
- ✗
Immediately escalate the issue to the sponsor and recommend rolling back the migration to the on-premises server to eliminate the risk.
Why it's wrong here
Rolling back discards completed migration work and does not address the add-in compatibility or synchronisation defects, so the remaining 900 users would still fail. Escalation suits unresolved risks exceeding the project manager's authority. Here the project manager should first analyse root causes and adjust the migration approach.
- ✓
Convene a meeting with the finance department to understand the criticality of the add-ins, and update the risk register with the new findings, then adjust the project schedule accordingly.
Why this is correct
Convening the finance department clarifies add-in criticality, and updating the risk register captures the compatibility and data-loss findings as formal risks. Adjusting the schedule then reflects the remaining 900 users realistically, satisfying the sponsor's go-live constraint through informed replanning rather than optimistic assumptions.
- ✗
Request additional budget to purchase a third-party migration tool that supports the add-ins and has better synchronization capabilities.
Why it's wrong here
Purchasing a new tool addresses synchronisation capability but not the custom add-in compatibility, which is an application-level issue the migration tool cannot fix. Procurement is correct when a validated capability gap exists. The project manager should first assess the defects and remediate add-ins before committing budget.
