The correct approach is to create a retention policy in Dynamics 365 that automatically deletes cases after 7 years, integrated with Microsoft Purview for centralized compliance management. This works because Dynamics 365 retention policies allow administrators to define automatic deletion timelines for records, while Microsoft Purview provides a unified governance layer to audit access and enforce data retention and deletion policies across the Microsoft ecosystem. On the MB-910 exam, this scenario tests your understanding that retention policies handle automated lifecycle management, not manual deletion or field-level security, which are common distractors. A key trap is confusing compliance requirements with security controls—deletion is a data governance function, not a permission setting. Memory tip: think “Retention = Time + Auto-Delete,” and remember that Purview is the central command center for all compliance policies.
MB-910 Practice Question: Explore the core capabilities of customer engagement apps in Dynamics 365
This MB-910 practice question tests your understanding of explore the core capabilities of customer engagement apps in dynamics 365. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Contoso Pharmaceuticals uses Dynamics 365 Customer Service to handle sensitive patient data. They have strict compliance requirements: only authorized users can view case details, and all access must be audited. The compliance officer wants to ensure that when a case is resolved, the case remains accessible for read-only for 7 years, after which it should be automatically deleted. Additionally, the IT administrator needs to set up a policy that automatically purges cases older than 7 years. The company also uses Microsoft Purview for data governance. Which approach should the administrator take?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a retention policy in Dynamics 365 that automatically deletes cases after 7 years, and integrate with Microsoft Purview for compliance.
Option D is correct because retention policies in Dynamics 365 can automatically delete records after a specified period, and integration with Microsoft Purview allows centralized management. Option A is incorrect because manual deletion is prone to error and not automatic. Option B is incorrect because field-level security does not handle deletion. Option C is incorrect because deletion is not related to compliance.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Create a retention policy in Dynamics 365 that automatically deletes cases after 7 years, and integrate with Microsoft Purview for compliance.
Why this is correct
Retention policies automate deletion and meet compliance requirements.
Related concept
Static NAT maps one inside address to one outside address.
✗
Create a manual process to delete cases older than 7 years every month.
Why it's wrong here
Manual deletion is not automated and may miss deadlines.
✗
Disable case records after 7 years using a business rule.
Why it's wrong here
Business rules cannot delete records; they only enforce logic.
✗
Use field-level security to hide case data after 7 years.
Why it's wrong here
Field-level security does not delete data; it only restricts visibility.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related MB-910 NAT questions on configuration and troubleshooting.
