DBS-C01 Deployment and Migration Practice Question
This DBS-C01 practice question tests your understanding of deployment and migration. 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.
A company is migrating a 2 TB MongoDB database to Amazon DocumentDB. Which TWO factors should be considered when planning 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
✓
Source MongoDB version compatibility with DocumentDB.
Option D is correct because Amazon DocumentDB is wire-protocol-compatible with MongoDB 3.6 and 4.0, but not with all MongoDB versions. If the source MongoDB version is older or newer than these supported versions, you may need to upgrade or downgrade the source before migration. Compatibility also affects features like indexes, aggregation pipelines, and data types, which can cause migration failures if not addressed. Option E is correct because network bandwidth and latency directly impact the time required to transfer a 2 TB dataset. Insufficient bandwidth can lead to prolonged migration windows or failures. Additionally, high latency can degrade performance of replication-based tools. Therefore, assessing network capacity and optimizing the transfer path is a critical planning factor.
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 often focus on operational features of DocumentDB (like automated backups or authentication) as migration planning factors, when the actual critical considerations are source version compatibility and network constraints that directly affect the feasibility and duration of the migration.
Detailed technical explanation
How to think about this question
During migration, network bandwidth and latency (Option E) directly impact the time required for the initial sync and ongoing change data capture. For a 2 TB database, even with compression, transferring over a low-bandwidth link can take days or weeks, and high latency can cause replication lag or timeouts in tools like mongodump/mongorestore or AWS Database Migration Service (DMS). DocumentDB's wire protocol compatibility is not 100% identical to MongoDB; for example, it does not support MongoDB's eval command or certain index types like TTL indexes on capped collections, which must be refactored before migration.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
