Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Inadequate security controls in the new system
Why it's wrong here
Security is important but data migration risks are more specific to the implementation phase.
- ✗
Insufficient training of end users on the new system
Why it's wrong here
While training is important, data migration poses a more direct risk to data integrity and system functionality.
- ✓
Incomplete or inaccurate data conversion from legacy systems
Why this is correct
Data conversion errors can corrupt the new system's data, leading to financial and operational issues.
- ✗
Lack of integration testing between modules
Why it's wrong here
Integration testing is important but data migration risks are often more fundamental and harder to rectify post-implementation.
