How to Automatically Categorize Cases with Routing Rule Sets

An organization wants to automatically categorize incoming cases based on keywords in the subject line. Which feature should be used?

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.

⚠ Common exam trap

Many exam-takers 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.

Same concept, more angles

3 more ways this is tested on MB-910

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?

medium

A.Configure Service Level Agreements (SLAs)
✓ B.Set up Routing Rule Sets
C.Create separate queues for each tier
D.Enable Unified Routing

Why B: Routing Rule Sets allow automatic assignment of cases to queues based on conditions such as the customer's support tier (Gold, Silver, Bronze). This feature enables the manager to define rules that evaluate case attributes and route them to the appropriate queue without manual intervention. Option A is incorrect because Service Level Agreements (SLAs) define response and resolution time targets, not routing logic. Option C is incorrect because simply creating separate queues does not provide automatic routing; rules are needed to direct cases into those queues. Option D is incorrect because Unified Routing is a more advanced feature that may involve additional licensing and complexity, while Routing Rule Sets are the standard, straightforward solution 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?

easy

A.queue-priority-high
✓ B.queue-emea-high
C.queue-default
D.queue-emea

Why B: 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?

medium

A.Service Level Agreement (SLA)
B.Entitlements
✓ C.Routing rules
D.Dynamics 365 Copilot

Why C: (Routing rules) is correct because routing rules can be configured to automatically prioritize cases based on criteria such as customer tier and issue severity. Option A (SLA) is incorrect because SLAs define response and resolution time commitments, not prioritization logic. Option B (Entitlements) is incorrect because entitlements specify the support coverage (e.g., number of incidents or hours) for a customer, not how to prioritize cases. Option D (Dynamics 365 Copilot) is incorrect because Copilot is an AI-powered assistant that helps with tasks like drafting responses, not for case prioritization.
