DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 running an Amazon RDS for SQL Server DB instance. The company needs to capture changes to a specific table and replicate them to an Amazon S3 bucket in near real time. Which AWS service should be used to achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Database Migration Service (AWS DMS) with ongoing replication
AWS DMS with ongoing replication (change data capture) can capture changes and replicate them to S3. Option B (AWS Glue) is for ETL jobs, not real-time CDC. Option C (Amazon Kinesis Data Streams) could ingest data but requires additional configuration. Option D (Amazon RDS for SQL Server replication) does not directly write to S3.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 batch ETL, not real-time change data capture.
✓
AWS Database Migration Service (AWS DMS) with ongoing replication
Why this is correct
DMS supports change data capture to replicate changes to S3 nearly in real time.
Related concept
Static NAT maps one inside address to one outside address.
✗
Amazon RDS for SQL Server native replication
Why it's wrong here
Native replication does not directly write to S3.
✗
Amazon Kinesis Data Streams
Why it's wrong here
Kinesis can ingest data but requires additional setup to capture database changes.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DBS-C01 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: AWS Database Migration Service (AWS DMS) with ongoing replication — AWS DMS with ongoing replication (change data capture) can capture changes and replicate them to S3. Option B (AWS Glue) is for ETL jobs, not real-time CDC. Option C (Amazon Kinesis Data Streams) could ingest data but requires additional configuration. Option D (Amazon RDS for SQL Server replication) does not directly write to S3.
What should I do if I get this DBS-C01 question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DBS-C01 NAT questions on configuration and troubleshooting.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
