The answer is to check the streaming API ingestion logs for errors or throttling. This is correct because when real-time streaming data from the online store shows a 24-hour delay, the issue lies in the ingestion pipeline itself—likely API rate limits, connectivity failures, or processing bottlenecks that prevent the data from flowing immediately into Customer Insights. On the MB-910 exam, this scenario tests your understanding of how streaming ingestion differs from batch ingestion and where to look first when data freshness breaks. A common trap is to assume the problem is with the ERP batch files or the loyalty weekly update, but the key clue is that only the real-time stream is delayed. Memory tip: think “stream = speed” — if streaming data is slow, always start with the API logs, not the source system.
MB-910 Describe Dynamics 365 Customer Insights Practice Question
This MB-910 practice question tests your understanding of describe dynamics 365 customer insights. 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.
You are the Dynamics 365 administrator for a multinational retail chain. The company uses Dynamics 365 Customer Insights to create a 360-degree view of customers. They have data from three systems: an on-premises ERP system containing customer purchases, an online store database with browsing behavior, and a loyalty program database. The ERP data is updated daily via batch files, the online store data is streamed in real-time, and the loyalty data is updated weekly. The marketing team wants to create a segment of customers who have made a purchase in the last 30 days and have browsed at least three product pages in the last week. However, they notice that some customers who meet these criteria are not appearing in the segment. Upon investigation, you find that the purchase data from the ERP is being ingested correctly, but the browsing data from the online store seems to have a delay of up to 24 hours. Which action should you take to resolve the issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the streaming API ingestion logs for errors or throttling.
The browsing data from the online store is streamed in real-time, but the investigation reveals a delay of up to 24 hours. This indicates that the streaming API may be experiencing errors or throttling, which prevents the data from being ingested promptly. Checking the streaming API ingestion logs will identify the root cause, such as rate limits or connectivity issues, allowing you to resolve the delay and ensure the segment includes all qualifying customers.
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.
✗
Adjust the data unification rules to match records more aggressively.
Why it's wrong here
Unification is not causing the delay.
✗
Change the ERP data import schedule to run more frequently.
Why it's wrong here
ERP data is not the issue.
✗
Reconfigure the online store data source to use a batch import instead of streaming.
Why it's wrong here
Streaming is appropriate; batch would increase delay.
✓
Check the streaming API ingestion logs for errors or throttling.
Why this is correct
Identifies and resolves streaming delays.
Clue confirmation
The clue word "least" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume the streaming data is inherently real-time and ignore the possibility of ingestion failures, leading them to incorrectly modify the data source type or unrelated unification rules instead of investigating the streaming pipeline for errors or throttling.
Detailed technical explanation
How to think about this question
Dynamics 365 Customer Insights uses a streaming ingestion API (typically via Azure Event Hubs or HTTP endpoints) to process real-time data. Throttling can occur if the data volume exceeds the provisioned throughput units, causing delays or dropped events. Checking the ingestion logs (e.g., via the Data sources > Streaming section or Azure Monitor) reveals error codes like 429 (Too Many Requests) or 503 (Service Unavailable), which indicate throttling or transient failures that need to be addressed by adjusting throughput or retry policies.

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.
