Quick Answer
The answer is routing rule set. This feature is correct because routing rule sets in Dynamics 365 Customer Service allow you to define conditions based on specific fields, such as the subject line, to automatically categorize and route incoming cases. By configuring keywords in the subject line as conditions, the system can assign cases to the appropriate queue or support tier without manual intervention, directly fulfilling the requirement for automatic categorization based on subject line keywords. On the Microsoft Dynamics 365 Fundamentals CRM MB-910 exam, this topic tests your understanding of case management automation, often appearing as a scenario where you must distinguish routing rule sets from other features like queues or automatic record creation rules. A common trap is confusing routing rule sets with service-level agreements (SLAs), but remember that routing rule sets handle categorization and assignment, not timelines. Memory tip: think of a “route” as a road sign—keywords in the subject line act as the signposts that direct each case to its correct destination.

Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
An organization wants to automatically categorize incoming cases based on keywords in the subject line. Which feature should be used?
Copilot for Service
Why wrong: Copilot can suggest categories but does not automatically set them.
Routing rule set
Correct: Routing rules can update fields like case category based on conditions.
SLA
Why wrong: SLA does not categorize cases.
Queue
Why wrong: Queues route cases but do not automatically set categories.

Correct answer & explanation
Routing rule set
Routing rule sets in Dynamics 365 Customer Service allow you to define conditions based on fields like the subject line to automatically categorize and route incoming cases. By specifying keywords in the subject line as conditions, the system can assign cases to the appropriate queue or support tier without manual intervention. This directly meets the requirement for automatic categorization based on subject line keywords.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Copilot for Service
Why it's wrong here
Copilot can suggest categories but does not automatically set them.
Routing rule set
Why this is correct
Correct: Routing rules can update fields like case category based on conditions.

SLA
Why it's wrong here
SLA does not categorize cases.
Queue
Why it's wrong here
Queues route cases but do not automatically set categories.
Common exam traps
The trap here is that candidates often confuse the purpose of Queues (storage and assignment) with the routing logic that actually categorizes cases, leading them to select Queue instead of Routing rule set.
Detailed technical explanation
Routing rule sets work by evaluating case attributes (e.g., 'subject' field) against defined conditions using the Dynamics 365 workflow engine. When a case is created or updated, the system runs the rule set in order of priority; the first matching rule triggers an action such as assigning the case to a specific queue or user. This allows for granular, rule-based automation without custom code, and supports complex conditions using operators like 'contains', 'begins with', or 'equals' for keyword matching.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A customer service manager wants to automatically assign cases to the appropriate queue based on the customer's support tier (Gold, Silver, Bronze). Which Dynamics 365 Customer Service feature should be configured?
mediumWhy B: Option C is correct because Routing Rules allow automatic case assignment to queues based on conditions like customer tier. Option A is wrong because Queues are where cases are stored, not dynamically assigned based on conditions. Option B is wrong because Service Level Agreements (SLAs) define response times, not routing. Option D is wrong because Unified Routing is a newer feature but requires additional licensing and setup; traditional Routing Rules are simpler for this scenario.
Variation 2. Refer to the exhibit. { "routes": [ { "name": "Priority Routing", "conditions": [ {"attribute": "prioritycode", "operator": "eq", "value": 2}, {"attribute": "new_region", "operator": "eq", "value": "EMEA"} ], "queueId": "queue-emea-high" } ] } A case with prioritycode = 2 and new_region = 'EMEA' is created. To which queue will it be routed?
easyWhy B: Option B is correct because the conditions match both criteria, and the queueId is 'queue-emea-high'. Other options are not referenced in the exhibit.
Variation 3. A company wants to automatically prioritize cases based on customer tier and issue severity. Which feature should they configure in Dynamics 365 Customer Service?
mediumWhy C: Option D is correct because routing rules can be set to prioritize cases based on criteria. Option A is wrong because SLA defines response times, not prioritization. Option B is wrong because Copilot is for AI assistance. Option C is wrong because entitlements define support coverage, not priority.
