PCDOE Migrate Database Solutions Practice Question
This PCDOE practice question tests your understanding of migrate database solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
An organization is migrating from Teradata to BigQuery. They have 20 TB of data, complex BTEQ scripts, and require near-zero downtime. Which THREE components should be part of their migration plan? (Choose THREE.)
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
✓
Schema Conversion Tool (SCTS)
Schema Conversion Tool (SCTS) is correct because it automates the conversion of Teradata-specific DDL, BTEQ scripts, and stored procedures into BigQuery-compatible SQL. This is critical for migrating 20 TB of data and complex BTEQ scripts without manual rewriting, reducing errors and accelerating the migration timeline.
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
Cisco often tests the distinction between migration tools for homogeneous vs. heterogeneous migrations, and the trap here is that candidates confuse Database Migration Service (DMS) as a general-purpose tool when it only supports specific source/target pairs like MySQL to Cloud SQL, not Teradata to BigQuery.
Detailed technical explanation
How to think about this question
BTEQ scripts often use Teradata-specific SQL extensions like QUALIFY, MACROs, and SET/VOLATILE tables, which SCTS parses and translates into BigQuery equivalents (e.g., QUALIFY becomes a window function filter). For near-zero downtime, cutover planning with rollback (Option C) must include a dual-run phase where both systems process live traffic, with rollback procedures using change data capture (CDC) or timestamp-based replication to revert if issues arise. BigQuery Data Transfer Service (Option D) automates bulk historical data loads from Teradata via scheduled exports (e.g., using Teradata Parallel Transporter or Avro files) and can handle 20 TB incrementally, but it does not handle schema or script conversion.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
