The answer is to enable Amazon CloudWatch Contributor Insights for DynamoDB. This service analyzes table access logs to automatically surface the most frequently accessed partition keys, directly revealing which specific keys are creating hot partitions and causing throttling. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your ability to distinguish between monitoring tools: Contributor Insights is purpose-built for identifying top talkers and hot keys in DynamoDB, whereas options like CloudWatch Logs Insights, X-Ray, or DynamoDB Streams lack partition-level granularity. A common trap is reaching for CloudWatch Logs Insights, but that requires enabling VPC Flow Logs and manual querying, making it far less efficient than Contributor Insights, which provides automatic, real-time analysis. Memory tip: think of Contributor Insights as a “hot key spotlight” — it shines directly on the partition keys causing the heat, while other tools only show the smoke.
DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. 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 has a production Amazon DynamoDB table with on-demand capacity. The table experiences occasional throttling due to hot partitions. The operations team wants to implement a solution to identify the specific partition keys causing the throttling. What is the MOST efficient approach?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Amazon CloudWatch Contributor Insights for DynamoDB.
Option D is correct because Amazon CloudWatch Contributor Insights can analyze DynamoDB logs and identify the most accessed partition keys, helping to pinpoint hot partitions. Option A is incorrect because CloudWatch Logs Insights requires enabling VPC Flow Logs, which is not specific to DynamoDB. Option B is incorrect because AWS X-Ray traces requests but does not provide partition-level metrics. Option C is incorrect because DynamoDB Streams capture changes, not access patterns.
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.
✗
Enable AWS X-Ray tracing on the application and analyze traces.
Why it's wrong here
X-Ray traces requests but does not reveal specific partition keys causing throttling.
✗
Enable VPC Flow Logs and use CloudWatch Logs Insights to query the logs.
Why it's wrong here
VPC Flow Logs capture network traffic, not DynamoDB partition access.
✓
Enable Amazon CloudWatch Contributor Insights for DynamoDB.
Why this is correct
Contributor Insights analyzes access patterns and identifies top partition keys.
Related concept
Static NAT maps one inside address to one outside address.
✗
Enable DynamoDB Streams and process the stream records to identify hot keys.
Why it's wrong here
Streams capture item changes, not read/write access patterns.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
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: Enable Amazon CloudWatch Contributor Insights for DynamoDB. — Option D is correct because Amazon CloudWatch Contributor Insights can analyze DynamoDB logs and identify the most accessed partition keys, helping to pinpoint hot partitions. Option A is incorrect because CloudWatch Logs Insights requires enabling VPC Flow Logs, which is not specific to DynamoDB. Option B is incorrect because AWS X-Ray traces requests but does not provide partition-level metrics. Option C is incorrect because DynamoDB Streams capture changes, not access patterns.

Variation 1. A company is running an Amazon DynamoDB table with on-demand capacity mode. The table experiences occasional throttling during peak hours. The application team wants to understand the read/write patterns to optimize the table design. Which approach should the database specialist take to analyze the throttling events?
hard
A.Enable DynamoDB Accelerator (DAX) to cache reads and reduce throttling.
B.Use AWS CloudTrail to log all DynamoDB API calls and analyze the logs.
C.Switch to provisioned capacity mode with auto scaling to handle the spikes.
✓ D.Enable CloudWatch Contributor Insights for DynamoDB to identify throttled requests.
Why D: CloudWatch Contributor Insights analyzes high-cardinality attributes and provides detailed information about throttling requests, such as which items or partitions are causing throttling.
