The correct answer is to increase the provisioned throughput (RU/s) for the container. This is because the Normalized RU Consumption metric measures the percentage of your allocated request units currently in use; a sustained value above 90% signals that your container is operating at the edge of its capacity, making it highly susceptible to throttling (HTTP 429 errors) during any sudden traffic burst. On the DP-203 exam, this scenario tests your understanding of how to interpret Azure Monitor metrics to proactively scale Cosmos DB resources. A common trap is to assume you should optimize queries or add indexing first, but when normalized RU consumption is consistently high, the immediate solution is to raise the provisioned throughput—not to redesign the data model. Remember the memory tip: "90% is the red line—throttling is just a spike away, so raise the RU/s to stay in the safe zone."
DP-203 Practice Question: Monitor and optimize data storage and processing
This DP-203 practice question tests your understanding of monitor and optimize data storage and processing. 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.
You are monitoring an Azure Cosmos DB account using Azure Monitor. The 'Normalized RU Consumption' metric for a container is consistently above 90%. You need to ensure that the container can handle the load without throttling. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the provisioned throughput (RU/s) for the container.
The 'Normalized RU Consumption' metric indicates the percentage of provisioned throughput (RU/s) being used. Consistently above 90% means the container is operating near its capacity limit, risking throttling (HTTP 429 errors) during traffic spikes. Increasing the provisioned throughput (RU/s) directly raises the capacity, allowing the container to handle the load without throttling.
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.
✗
Change the partition key to a different property.
Why it's wrong here
Partition key affects data distribution but does not change total provisioned throughput.
✓
Increase the provisioned throughput (RU/s) for the container.
Why this is correct
Increasing RU/s provides more capacity, lowering the normalized RU consumption percentage for the same workload.

✗
Switch the account to serverless mode.
Why it's wrong here
Serverless mode has its own scaling limits and may still throttle if consumption exceeds max RU/s.
✗
Modify the indexing policy to exclude unused paths.
Why it's wrong here
Reducing indexing cost per operation may help but the normalized RU consumption is about capacity utilization, not per-operation cost.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse optimizing RU consumption (e.g., indexing or partition key changes) with the need to increase capacity when the metric already shows the system is at its limit, leading them to choose options that reduce per-request cost rather than addressing the throughput ceiling.
Detailed technical explanation
How to think about this question
Normalized RU Consumption is the maximum RU consumption across all physical partitions, so a value above 90% indicates that at least one partition is near its throughput limit. Increasing RU/s scales throughput uniformly across all partitions, but if a hot partition exists, you may also need to review partition key design to avoid uneven load. In practice, you should first check the 'PartitionKeyRUConsumption' metric to identify if a single partition is the bottleneck.

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 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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
