DBS-C01 Deployment and Migration Practice Question

This DBS-C01 practice question tests your understanding of deployment and migration. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 wants to migrate a self-hosted MongoDB database to Amazon DocumentDB. They need to convert the schema. Which AWS service should they use?

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

✓

AWS Schema Conversion Tool (SCT)

AWS Schema Conversion Tool (SCT) is the correct choice because it is specifically designed to convert database schemas from one engine to another, including from MongoDB to Amazon DocumentDB. SCT analyzes the source schema, identifies incompatible objects, and generates a target schema that is compatible with DocumentDB, handling data type mappings, index conversions, and other structural differences.

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.

  • ✗

    AWS Glue

    Why it's wrong here

    Glue is for ETL, not specifically for schema conversion.

  • ✗

    AWS Database Migration Service (DMS)

    Why it's wrong here

    DMS handles data migration but not schema conversion.

  • ✓

    AWS Schema Conversion Tool (SCT)

    Why this is correct

    SCT can convert MongoDB schemas to DocumentDB-compatible format.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Amazon Athena

    Why it's wrong here

    Athena is for querying data, not schema conversion.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse AWS DMS as a full migration solution for heterogeneous databases, not realizing that DMS only handles data movement and relies on SCT for schema conversion when the source and target engines differ.

Detailed technical explanation

How to think about this question

SCT works by connecting to the source MongoDB instance, extracting the schema (collections, indexes, document structures), and then generating a DocumentDB-compatible schema that may involve flattening nested documents or converting BSON data types to DocumentDB equivalents. In real-world migrations, SCT also provides an assessment report that highlights conversion complexity and any manual remediation steps needed, such as handling unsupported MongoDB features like $lookup aggregation or geospatial indexes that require adjustment for DocumentDB.

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.
