PCDE Migrate data solutions Practice Question

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
✓
The SCTS tool did not fully convert the Teradata-specific date functions to BigQuery equivalents.
SCTS converts syntax but may not perfectly translate all functions; manual review is often needed for specific date functions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The BigQuery Data Transfer Service is required for date conversion.
Why it's wrong here
Data Transfer Service is for data loading, not schema conversion.
- ✗
The Teradata source has a different date format that is incompatible with BigQuery.
Why it's wrong here
Format differences can be handled in conversion, but the issue is function conversion.
- ✓
The SCTS tool did not fully convert the Teradata-specific date functions to BigQuery equivalents.
Why this is correct
Some Teradata date functions have no direct BigQuery equivalent and require manual adjustment.
- ✗
BigQuery does not support date arithmetic.
Why it's wrong here
BigQuery supports date arithmetic via DATE_ADD, DATE_DIFF, etc.
