- A
Instruct the team to proceed with the migration of the remaining users using the same tool to avoid further delays.
Why wrong: Incorrect: Continuing with the same flawed process will likely repeat the issues, causing more delays and data loss.
- B
Immediately escalate the issue to the sponsor and recommend rolling back the migration to the on-premises server to eliminate the risk.
Why wrong: Incorrect: Rolling back abandons the project objectives and may not be necessary; escalation is appropriate but should be accompanied by a plan, not a recommendation to cancel.
- C
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.
Correct: This approach identifies the root cause, updates documentation, and replans, which is a proper project management response.
- D
Request additional budget to purchase a third-party migration tool that supports the add-ins and has better synchronization capabilities.
Why wrong: Incorrect: This may help, but it's premature; the project manager should first investigate the add-in requirements and assess if the existing tool can be configured or if the add-ins can be modified.
PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
This PK0-005 practice question tests your understanding of basics of it infrastructure and it project management. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.

"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
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.
Option C is 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may 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.
Detailed technical explanation
How to think about this question
Custom email add-ins for on-premises Exchange often use legacy protocols like MAPI over RPC or EWS, which are not fully supported in Microsoft 365's modern authentication and Graph API environment. The migration tool's failure to synchronize mailbox items may stem from unsupported item types (e.g., custom forms, permissions, or folder-level properties) that are not mapped correctly during the cutover. In real-world scenarios, a phased migration with a pilot batch is critical to uncover such compatibility issues before scaling, and the risk register should be updated with the specific add-in dependencies and a contingency plan, such as using the Microsoft 365 Deployment Advisor or third-party tools like BitTitan MigrationWiz.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
