The answer is to increase the write capacity units for the table, examine CloudWatch metrics, and implement exponential backoff. These three actions directly address DynamoDB throttling exceptions by either increasing the available throughput or managing the request rate to stay within provisioned limits. CloudWatch metrics like ConsumedWriteCapacityUnits and ThrottledWriteEvents reveal patterns of capacity exhaustion, while exponential backoff ensures retries don’t compound the issue. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your ability to distinguish between reactive fixes (scaling capacity) and proactive client-side strategies (backoff), with a common trap being to confuse DynamoDB Streams or read consistency models as solutions—neither affects write throttling. Remember the mnemonic “C-B-I”: CloudWatch, Backoff, Increase capacity.
DBS-C01 Monitoring and Troubleshooting Practice Question
This DBS-C01 practice question tests your understanding of monitoring and troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Which THREE actions should be taken to troubleshoot a high number of ThrottlingExceptions from Amazon DynamoDB? (Choose 3.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Examine the ConsumedWriteCapacity and ThrottledWriteCount metrics in CloudWatch
A, C, D are correct. Examining CloudWatch metrics helps identify throttling patterns. Implementing exponential backoff is a best practice. Increasing provisioned capacity resolves throttling. B is wrong because enabling DynamoDB Streams does not affect throttling. E is wrong because changing consistency model does not affect write throttling.
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.
✓
Examine the ConsumedWriteCapacity and ThrottledWriteCount metrics in CloudWatch
Why this is correct
Helps identify if capacity is exceeded.
Related concept
Static NAT maps one inside address to one outside address.
✗
Enable DynamoDB Streams to offload writes
Why it's wrong here
Streams do not reduce throttling.
✓
Implement exponential backoff in the application
Why this is correct
Retries with backoff handle throttling gracefully.
Related concept
Static NAT maps one inside address to one outside address.
✓
Increase the write capacity units for the table
Why this is correct
More capacity reduces throttling.
Related concept
Static NAT maps one inside address to one outside address.
✗
Change the read consistency to eventual
Why it's wrong here
Consistency does not affect write throttling.
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 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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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.
