DP-700 Monitor and Optimize an Analytics Solution Practice Question
Exhibit
{
"query": "SELECT * FROM sales WHERE region = 'North'",
"status": "429",
"error": "Too Many Requests",
"workload": "Power BI",
"timestamp": "2023-10-27T10:00:00Z"
}Refer to the exhibit. You are reviewing the monitoring logs for your Fabric capacity. What is the most likely cause of the error shown in the exhibit?
⚠ Common exam trap
Candidates often mistake a 429 status code for a missing permission or invalid connection string, ignoring the capacity unit and request rate limits inherent to Fabric workloads.
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
✓
The Fabric capacity is experiencing throttling.
The '429 Too Many Requests' error indicates that the Fabric capacity has reached its limits for concurrent requests or resource consumption. This occurs when the workload exceeds the allocated capacity units (CU) or the throughput limits set for that specific capacity type. To resolve this, you must analyze if the workload needs more resources, requires optimization, or needs to be distributed across different capacities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The underlying data source is offline.
Why it's wrong here
If the data source were offline, you would receive a connection timeout or a network error, not a '429 Too Many Requests' status. A 429 error is strictly related to capacity throttling, meaning the service is rejecting incoming requests because they exceed the resource limits.
- ✓
The Fabric capacity is experiencing throttling.
Why this is correct
A 429 status code explicitly signals that the capacity is being throttled due to excessive usage or concurrency limitations. When the aggregate demand of all operations exceeds the burstable or sustained limits of the purchased capacity, Fabric pauses requests to maintain stability for all users.
- ✗
The user does not have read permissions.
Why it's wrong here
Lack of permissions results in a '403 Forbidden' or '401 Unauthorized' error code. The 429 error is specifically reserved for rate limiting and service throttling, which indicates the request is authenticated correctly but is blocked due to excessive resource utilization on the capacity.
- ✗
The query contains a syntax error.
Why it's wrong here
Syntax errors result in '400 Bad Request' or specific SQL engine errors during the compilation phase. A 429 error is generated by the load balancer or the service management layer, not by the SQL engine itself, regardless of the query content or its validity.
