Sample question 1 · Plan the architecture and solution design

A production environment has become slow. Which LCS capability shows SQL query statistics and environment health history?

1. A. Asset library
2. B. Environment monitoring
3. C. Business process modeler
4. D. Issue search

Show answer and explanation

Answer: B

Environment monitoring in LCS reports health metrics, running activity and SQL insights over time. The asset library stores packages, the business process modeler documents processes, and issue search finds known issues.

Sample question 2 · Apply developer tools

In Finance and Operations, what is the unit that gets compiled and deployed, and can contain one or more models?

1. A. Project
2. B. Solution
3. C. Package
4. D. Layer

Show answer and explanation

Answer: C

A package is the deployment and compilation unit and can hold several models. A project (Visual Studio) is only a container for working on elements.

Sample question 3 · Design and develop AOT elements

You need a status field with fixed values that partners may extend later. What do you create?

1. A. A string EDT with a lookup list
2. B. A base enum with IsExtensible set to Yes
3. C. A table with a status code and no relations
4. D. A container field

Show answer and explanation

Answer: B

Base enums model fixed value sets. With IsExtensible = Yes, other models can add values through enum extensions. A table would work but is heavier and is not what the pattern calls for.

Sample question 4 · Develop and test code

What must a Chain of Command wrapper method contain so the original logic still runs?

1. A. A call to super()
2. B. A call to next followed by the method name and its parameters
3. C. A call to the base class by name
4. D. An override of the method signature in the AOT

Show answer and explanation

Answer: B

A CoC method calls next methodName(args) to invoke the next wrapper or the original. Without it, the original logic is skipped, which is only allowed for methods marked Replaceable.

Sample question 5 · Implement reporting

Which base class does a report data provider (RDP) class extend for an SSRS report?

1. A. SrsReportDataProviderBase
2. B. SysOperationServiceBase
3. C. RunBaseReport
4. D. SrsReportRunController

Show answer and explanation

Answer: A

RDP classes extend SrsReportDataProviderBase and fill a temporary table that the report uses as a dataset. The controller starts the report.
