- A
The migration job will switch to one-time migration mode.
Why wrong: DMS does not automatically switch modes.
- B
The migration job will resume automatically from where it stopped.
The logical replication slot maintains the LSN position; after restart, DMS continues from that point.
- C
The migration job will fail and require a new full dump.
Why wrong: Replication slots persist across restarts; no full dump is needed.
- D
The migration job will continue but with increased latency until all WAL is replayed.
Why wrong: Latency may increase temporarily but not due to restart; DMS picks up from the slot.

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 performing a DMS continuous migration from PostgreSQL to Cloud SQL. The migration job is in the CDC phase. During a planned maintenance window, the source database is restarted. After restart, the DMS job continues to replicate but reports a lag. What is the impact of the restart on the migration?
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 migration job will resume automatically from where it stopped.
Once the replication slot is established, a restart does not require a full re-sync. The slot retains the position, and DMS will resume from the last committed transaction. Autovacuum may affect performance but does not stop replication.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 migration job will switch to one-time migration mode.
Why it's wrong here
DMS does not automatically switch modes.
- ✓
The migration job will resume automatically from where it stopped.
Why this is correct
The logical replication slot maintains the LSN position; after restart, DMS continues from that point.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
