Exhibit
Refer to the exhibit. The following is a snippet from a Customer Insights configuration:
{
"matchRule": {
"conditions": [
{
"attribute": "Email",
"operator": "ExactMatch",
"label": "Email"
}
]
}
}
You are configuring a match rule for data unification. What does this rule specify?
Refer to the exhibit. The following is a snippet from a Customer Insights configuration:
{
"matchRule": {
"conditions": [
{
"attribute": "Email",
"operator": "ExactMatch",
"label": "Email"
}
]
}
}
A
Records with the exact same email address are considered a match
Correct: ExactMatch means identical values.
B
Records with the same CustomerId are considered a match
Why wrong: Wrong: The attribute is Email, not CustomerId.
C
Records with the same name are considered a match
Why wrong: Wrong: The attribute is Email, not Name.
D
Records with similar email addresses are considered a match
Why wrong: Wrong: The operator is ExactMatch, not fuzzy.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Records with the exact same email address are considered a match
Option A is correct because in Dynamics 365 Customer Insights, a match rule defines the conditions under which two or more records are considered to represent the same entity (e.g., a customer). Specifying that records with the exact same email address are considered a match is a common and valid rule, as email addresses are typically unique identifiers. The rule uses exact matching logic, not fuzzy or similarity-based matching, to determine duplicates during data unification.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse match rules (which require exact matching) with deduplication or fuzzy matching rules, leading them to choose Option D which implies similarity-based matching, but the MB-910 exam specifically tests that match rules for data unification use exact criteria like email or phone.
Detailed technical explanation
How to think about this question
Under the hood, Dynamics 365 Customer Insights uses a two-step data unification process: map and match. The match rule defines the exact conditions (e.g., email equals email) to identify duplicate records across ingested data sources. This is critical when merging data from CRM, ERP, and marketing systems where each source may have its own CustomerId; the match rule allows the system to unify records without relying on a common identifier. A real-world scenario is unifying customer records from a legacy on-premises database and a cloud-based e-commerce platform, where only email addresses are consistently populated and reliable.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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.
