Question 101.

A company wants to identify whether a proposed customization is justified. What should the solution architect evaluate first?

1. Whether the customization addresses a validated business requirement
   2. Whether the developer prefers custom code
   3. Whether the legacy system used the same design
   4. Whether the customization can be completed quickly

Correct Answer: 1. Whether the customization addresses a validated business requirement

Explanation:

A customization should be driven by a confirmed business need rather than personal preference or familiarity with a legacy process. The architect should determine whether standard Dynamics 365 functionality, configuration, process changes, or a supported ISV solution can satisfy the requirement first. If a genuine gap remains, customization can then be assessed for value, cost, security, performance, maintainability, and upgrade impact. This approach helps reduce unnecessary technical debt and keeps the solution easier to support. The objective is not to avoid all custom development, but to ensure that each customization provides clear business value and fits the overall architecture.

Question 102.

A customer needs to exchange small amounts of data with an external system in near real time. What should the architect evaluate?

1. Only nightly batch processing
   2. Appropriate API or event-driven integration options
   3. Manual spreadsheet transfers
   4. Direct production database updates

Correct Answer: 2. Appropriate API or event-driven integration options

Explanation:

Near-real-time integration usually requires a pattern that can exchange data quickly without waiting for a scheduled batch process. The architect should evaluate supported APIs, business events, messaging, or other event-driven mechanisms based on the specific requirement. Important considerations include latency, transaction volume, availability, security, throttling, retries, and error handling. A synchronous API may be suitable when an immediate response is required, while event-driven processing can provide better decoupling. The selected approach should meet business timing needs without creating unnecessary load or tight dependencies between Dynamics 365 and the external application.

Question 103.

A global company is planning a standardized Dynamics 365 security model. What should the architect do when local regulations require different access restrictions in certain countries?

1. Ignore local requirements
   2. Grant all users identical permissions
   3. Apply a global security framework with controlled local variations
   4. Create unrelated security models with no governance

Correct Answer: 3. Apply a global security framework with controlled local variations

Explanation:

A global security framework can provide consistency while still allowing necessary local differences. The architect should define common principles such as least privilege, role-based access, and segregation of duties, then document and govern exceptions required by local law or business conditions. This approach reduces duplication and makes the security model easier to maintain. Completely independent local designs can become inconsistent and difficult to audit, while ignoring regulatory requirements may create compliance risks. Controlled variations allow the organization to balance enterprise standards with legitimate country-specific access requirements.

Question 104.

A nightly integration must process millions of records within a limited window. Which architectural factor is most important?

1. User interface layout
   2. Office internet browsing policy
   3. The number of training sessions
   4. Throughput, batching, scalability, and processing-window requirements**

Correct Answer: 4. Throughput, batching, scalability, and processing-window requirements

Explanation:

High-volume integrations must be designed around measurable workload characteristics. The architect should understand how many records must be processed, the available time window, expected throughput, concurrency, batching options, and platform limitations. The design should also address retries, error handling, monitoring, and reconciliation. Performance testing with representative volumes is essential to confirm that the process can complete reliably within the required window. User-interface design or training schedules do not determine integration scalability. Focusing on throughput and processing behavior helps prevent production bottlenecks and ensures the solution can handle peak workloads effectively.

Question 105.

A company wants to make sure that developers cannot accidentally overwrite each other’s work. What should the architect recommend?

1. Source control with an agreed branching strategy
   2. Development directly in production
   3. Manual copying of code files
   4. One shared developer account

Correct Answer: 1. Source control with an agreed branching strategy

Explanation:

Source control provides a reliable way to manage code changes, track history, and support collaboration among multiple developers. An agreed branching strategy helps teams work on different features or fixes without unnecessarily interfering with each other. It also supports code reviews, controlled merging, and release management. Source control should be integrated into the wider application lifecycle management process with builds, automated tests, and deployment controls. Manual file copying increases the risk of lost changes and makes auditing difficult. Shared accounts also reduce accountability. Structured development practices improve quality and make the solution easier to maintain over time.

Question 106.

A business process must continue even if an external system is temporarily unavailable. What should the solution architect consider?

1. A direct dependency with no retry capability
   2. An asynchronous design with queueing and recovery
   3. Manual entry for every transaction
   4. Disabling integration monitoring

Correct Answer: 2. An asynchronous design with queueing and recovery

Explanation:

Asynchronous processing can help decouple systems so that temporary outages do not immediately stop the business process. Transactions can be placed in a durable queue and processed when the dependent system becomes available again. The architect should include retry behavior, monitoring, logging, duplicate protection, and recovery procedures. The acceptable delay should still align with business requirements. Synchronous integration may be necessary when an immediate response is required, but it creates a stronger runtime dependency. When delay is acceptable, asynchronous architecture generally provides better resilience and operational flexibility.

Question 107.

A company wants to identify potential conflicts in user permissions before go-live. What should the project team review?

1. Printer permissions
   2. Office seating assignments
   3. Segregation of duties and security-role combinations
   4. Personal user preferences

Correct Answer: 3. Segregation of duties and security-role combinations

Explanation:

Security-role combinations should be reviewed to identify conflicts that could allow a user to perform incompatible responsibilities. Segregation of duties is particularly important for financial and approval processes where combining certain permissions could create fraud or compliance risk. The project team should test representative user roles, validate organizational access, and document any approved exceptions. Least privilege should also be applied so users receive only the permissions needed for their responsibilities. Performing this review before production helps reduce the risk of discovering security problems after users begin processing real transactions.

Question 108.

A project team wants to reduce risk when deploying a new release. What should the architect recommend?

1. Skip testing to shorten the schedule
   2. Allow developers to deploy at any time
   3. Remove the rollback plan
   4. Use controlled testing, approvals, deployment, and recovery procedures**

Correct Answer: 4. Use controlled testing, approvals, deployment, and recovery procedures

Explanation:

A controlled release process helps ensure that changes are validated before they affect production users. The process should include appropriate functional, integration, regression, security, and performance testing based on the scope of the release. Deployment steps should be documented, responsibilities assigned, and approvals obtained. The team should also understand how to recover or mitigate the change if a serious issue occurs. Uncontrolled deployments increase the chance of production disruption and make troubleshooting more difficult. A structured release approach provides traceability and allows stakeholders to make informed decisions about production readiness.

Question 109.

A company is migrating customer data from several legacy applications. What should be established before the first trial migration?

1. Data ownership, mapping, transformation, and validation rules
   2. Final production passwords
   3. User vacation schedules
   4. A plan to delete all source systems immediately

Correct Answer: 1. Data ownership, mapping, transformation, and validation rules

Explanation:

A successful migration depends on understanding where data comes from, who owns it, how it maps into Dynamics 365, and what transformations are required. Validation rules should define what makes a record acceptable and how duplicates, missing values, and invalid formats are handled. These decisions should be documented before trial migrations begin so results can be evaluated consistently. Rehearsals then help refine the process and expose issues before production cutover. Without clear ownership and mapping rules, teams may load inconsistent or incomplete information and spend significant time correcting problems later.

Question 110.

A customer wants to make business-critical reports consistent across multiple departments. What should the architect prioritize?

1. Separate calculations for every department
   2. Shared data definitions and governed metrics
   3. Manual reconciliation after every report run
   4. Removing data ownership responsibilities

Correct Answer: 2. Shared data definitions and governed metrics

Explanation:

Consistent reporting depends on agreement about what key business measures mean and how they are calculated. The architect should support common definitions for entities and metrics such as revenue, inventory, customers, and margin. Data ownership and authoritative sources should also be clear. If each department uses independent calculations, users may receive conflicting results even when they are looking at similar data. Governance helps ensure that reporting tools use consistent logic and appropriate sources. This improves trust in analytics and reduces time spent reconciling different versions of the same business information.

Question 111.

A company plans to use a third-party ISV solution with Dynamics 365. Which factor should the architect assess first?

1. Functional fit with the business requirement
   2. The vendor’s website design
   3. The size of the vendor’s office
   4. The product logo

Correct Answer: 1. Functional fit with the business requirement

Explanation:

The first question is whether the ISV solution actually addresses the business requirement effectively. Once functional fit is established, the architect should also evaluate integration patterns, security, scalability, licensing, support, release compatibility, vendor stability, and lifecycle impact. A product that looks attractive but does not satisfy the required capability should not proceed further. The solution should also fit the broader Dynamics 365 architecture and follow supported extension practices. A structured assessment helps prevent the organization from introducing unnecessary complexity or long-term dependency on a product that does not deliver sufficient business value.

Question 112.

A customer wants users to access only the legal entities relevant to their jobs. What should the security design include?

1. One unrestricted shared account
   2. Full access to all legal entities
   3. Organization-based access aligned with security roles
   4. Anonymous access for convenience

Correct Answer: 3. Organization-based access aligned with security roles

Explanation:

Security should reflect both what users are allowed to do and where they are allowed to do it. Organization-based access can restrict users to the legal entities or organizational units relevant to their responsibilities. Combined with appropriate security roles, this supports least privilege and helps prevent accidental or unauthorized access to data in other companies. The design should also consider reporting access and segregation-of-duties conflicts. Shared unrestricted accounts remove accountability and create unnecessary risk. Testing representative user personas before go-live helps confirm that organizational access is working as intended.

Question 113.

A custom batch process is taking longer as transaction volumes increase. What should the architect recommend first?

1. Remove monitoring
   2. Ignore the issue until production fails
   3. Add more manual steps
   4. Perform performance analysis and review the batch design**

Correct Answer: 4. Perform performance analysis and review the batch design

Explanation:

Increasing processing times can indicate that a batch design is not scaling with transaction growth. The architect should review workload characteristics, queries, batching logic, concurrency, dependencies, and scheduling. Performance measurements should identify where time is being spent before changes are proposed. The solution may benefit from improved batching, parallelism, indexing-related design considerations, or moving work to a more appropriate processing window. Monitoring should be retained so improvements can be validated. Making assumptions without analysis can lead to ineffective changes. A data-driven performance review helps identify the true bottleneck and appropriate remediation.

Question 114.

A company wants to ensure that integration failures are detected quickly. What should the solution architect include?

1. Monitoring, alerts, and meaningful error logging
   2. No logs to reduce storage
   3. Manual checks once per month
   4. Error deletion without investigation

Correct Answer: 1. Monitoring, alerts, and meaningful error logging

Explanation:

Operational teams need visibility into integration health so they can respond before failures significantly affect business processes. Monitoring should track important conditions such as failed transactions, unusual delays, unavailable endpoints, or growing queues. Alerts should notify the appropriate support team when intervention is required. Logs should contain enough information to diagnose the issue without exposing sensitive data unnecessarily. The design should also include ownership and recovery procedures. Without monitoring, failures may remain hidden until business users notice missing information, increasing downtime and making recovery more difficult.

Question 115.

A business wants to preserve ten years of records for compliance but does not need all of them in active transactional processing. What should the architect evaluate?

1. Deleting all old records
   2. Archival and retention strategies
   3. Keeping all data in personal spreadsheets
   4. Moving all records into custom forms

Correct Answer: 2. Archival and retention strategies

Explanation:

Historical records should be retained according to business, legal, and compliance requirements, but they do not always need to remain in the active transactional workload. The architect should evaluate archival options that preserve required data while reducing unnecessary operational volume. The design should consider retrieval needs, reporting, security, retention periods, storage cost, and deletion policies. Archived data should remain accessible to authorized users when audits or investigations require it. A deliberate retention strategy can improve system manageability while still satisfying compliance obligations. Simply deleting records or storing them in uncontrolled spreadsheets introduces significant risk.

Question 116.

A new feature requires data from three external systems. What should the architect do before approving the design?

1. Review only the user interface
   2. Assume all systems are always available
   3. Perform dependency and integration impact analysis
   4. Ignore error-handling requirements

Correct Answer: 3. Perform dependency and integration impact analysis

Explanation:

A feature that depends on multiple external systems can create complex runtime and operational dependencies. The architect should understand which systems provide data, how frequently it changes, what happens if one source is unavailable, and whether the business process can continue with delayed information. Integration volume, security, latency, retries, monitoring, and ownership should also be reviewed. An impact analysis can reveal whether the design is too tightly coupled or whether asynchronous patterns would improve resilience. Understanding dependencies before implementation reduces unexpected failures and helps the team design appropriate recovery and support procedures.

Question 117.

A company wants to improve maintainability by reducing duplicate custom code. What should the architect encourage?

1. Reusable components and common design patterns
   2. Separate implementations for every team
   3. Copying code into multiple projects
   4. Avoiding architecture standards

Correct Answer: 1. Reusable components and common design patterns

Explanation:

Reusable components reduce duplication and provide a consistent way to implement common functionality. The architect should define standards that encourage teams to reuse approved services, libraries, integration patterns, and other shared components where appropriate. This can reduce development effort, testing scope, and long-term maintenance. Shared components should have clear ownership, documentation, versioning, and regression testing because changes may affect multiple consumers. Copying similar code into separate solutions makes defects harder to fix consistently and increases technical debt. Reuse should be purposeful and balanced so shared components do not become unnecessarily complex.

Question 118.

A company plans a major update to Dynamics 365. What should be done with critical custom extensions before production deployment?

1. Ignore them because Microsoft updates do not affect customizations
   2. Test them in an appropriate non-production environment
   3. Delete them before every update
   4. Validate them only after production deployment

Correct Answer: 2. Test them in an appropriate non-production environment

Explanation:

Critical extensions should be validated against platform updates before those updates reach production. Testing can identify compatibility issues, regression defects, integration failures, or changed behavior while the team still has time to correct them. The scope should include business processes that rely on the extensions, not only the custom code itself. Automated regression testing can make repeated validation more efficient. Using supported extension patterns reduces risk, but it does not eliminate the need for testing. A controlled update process protects production stability and helps the organization adopt platform improvements with greater confidence.

Question 119.

A company is preparing for go-live and wants to reduce confusion during the cutover weekend. What should the project team have in place?

1. A detailed cutover plan with owners, timing, dependencies, and checkpoints
   2. Only an informal chat message
   3. No assigned responsibilities
   4. A decision to improvise activities during cutover

Correct Answer: 1. A detailed cutover plan with owners, timing, dependencies, and checkpoints

Explanation:

A detailed cutover plan coordinates the many activities required to transition into production. It should identify tasks, responsible owners, start and completion times, dependencies, validation points, and decision criteria. Data migration, integrations, security, batch schedules, communications, business validation, and support readiness should all be included. Contingency or recovery procedures should also be documented for critical activities. Rehearsing the plan can reveal missing dependencies and unrealistic timing assumptions. Clear ownership and checkpoints reduce uncertainty and help project leaders understand progress during a time-sensitive production transition.

Question 120.

A Dynamics 365 project has several unresolved low-risk issues before go-live. What should the solution architect recommend?

1. Hide the issues from stakeholders
   2. Cancel the project automatically
   3. Delete the issues from the tracking system
   4. Document the risks, owners, mitigation, and acceptance decisions**

Correct Answer: 4. Document the risks, owners, mitigation, and acceptance decisions

Explanation:

Not every unresolved issue necessarily prevents go-live, especially when its impact is low and a practical workaround exists. However, the remaining risks should be transparent and formally governed. Each issue should have an owner, an assessment of business and technical impact, a mitigation or remediation plan, and an expected resolution timeline where appropriate. Relevant stakeholders should understand and accept the residual risk. Issues affecting security, compliance, data integrity, or critical operations may require stronger action. Formal documentation ensures that the go-live decision is based on known facts rather than incomplete information.
