What is Chain of Command (CoC)? - Quiz

Q: Which of the following are examples of a privilege? (Select all that apply)

A. Being a system administrator and Processing deposits
B. Canceling a payment
C. Managing system security
D. Both B & C

Correct Option: D
Remarks:

Explanation:

Justification:

A system administrator is a role. Therefore, being a system administrator does not represent a privilege.
Canceling a payment represents permission to perform a specific task in the system. This is a privilege.
Managing system security represents a duty. It encompasses many permissions or tasks.
Processing deposits also represents a specific task. Permission to perform this task is defined by a privilege.

Q:
You are developing a Dynamics 365 application. You need to extend a base class method but the method is marked as final.

You need to override the restriction and wrap the final method in an extension class.

What attribute should you use?

A. Hookable(false)
B. Hookable(true)
C. Wrappable(true)
D. Wrappable(false)

Correct Option: C
Remarks:

Explanation:

Public and protected methods that are marked as final can't be wrapped in extension classes. You can override this restriction by using the Wrappable attribute and setting the attribute parameter to true ([Wrappable(true)]). Similarly, to override the default capability for (non-final) public or protected methods, you can mark those methods as non-wrappable ([Wrappable(false)]).

The Wrappable(true) attribute can be used to override the restriction and allow final methods to be wrapped in extension classes. Hookable(true) does not influence chain of command wrapping. Wrappable(false) marks methods as non-wrappable. Hookable(false) makes the method unable to be wrapped in an extension class.

class AnyClass2 
{
    [Wrappable(false)]
    public void doSomething(str message) {...}

    [Wrappable(true)]
    final public void doSomethingElse(str message) {...}
}

Q:
You are a Dynamics 365 Finance developer.
You need to create an extension class.
Which action should you perform?

A. Mark the class as final.
B. Add the class buffer as the first parameter.
C. Mark the class as protected.
D. Mark the class as public.

Correct Option: A
Remarks:

Explanation:

Extension classes are final classes that are adorned with the ExtensionOf attribute and that also have a name that has the _Extension suffix.
Because the classes are instantiated by the runtime system, it's not meaningful to derive from the extension class. Therefore, the extension class must be marked as final.

Q:
DRAG DROP -
You are a Dynamics 365 Finance developer.
Users must be able to view a filtered customer list from within a workspace.
You need to add the customer form to a workspace.
Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them on the correct order.
Select and Place:

A. 3, 2, 1, 4
B. 4, 2, 1, 3
C. 1, 2, 3, 4

Correct Option: A
Remarks:

Explanation:

Step 1:Open the customer form and apply filters to the grid.

To add a list to a workspace, first sort or filter the list on the page so that it shows the information as you want it to appear in the workspace.

Step2:Select the Options actions pane tab and then select Add to workspace

step3: Select Workspace and Presentation options

Step 4: Select Configure -

After you select Configure, a dialog box appears, where you can select the columns that should appear in the list in the workspace.

Q:
You are a Dynamics 365 Finance developer. You have two tables as shown in the following exhibit:

You need to configure Table1 to ensure that records cannot be deleted from Table1 if Table2 contains related records.
Which value should you use for the OnDelete property?

A. None
B. Cascade
C. Cascade + Restricted
D. Restricted

Correct Option: D
Remarks:

Explanation:

Example of Restricted -
Suppose we have two tables (Customer & Order) and the relation is of One-To-Many i.e Customer can have many orders.
So on a parent table i.e.(Customer) if I set a delete action property to RESTRICTED for Order table. Then If I go and delete the record from a Customer table. It will first check the record in the child table and if exist that warning prompt saying that first we need to delete a record from child table.
Incorrect Answers:
B: Example of Cascade:
Suppose we have two tables (Customer & Order) and the relation is of One-To-Many i.e. Customer can have many orders.
So on a parent table i.e.(Customer) if I set a delete action property to CASCADE for Order table. Then If I go and delete the record from a Customer table. It will also delete all the related records in Order table automatically.
C: Example of Cascade + Restricted
Suppose we have three tables (Person ,Customer & Order) Now Person is a parent of Customer table, and Customer is a parent of Order table having (One-To-

Many) relations -
If I set a Delete action property on Person table to CASCADE for customer table and If I set a Delete Action property on a CUSTOMER table for Order table to
CASCADE +RESTRICTED.
So if I delete a record from Customer table then It will first check the record in the child table(order table) and if exist that warning prompt saying that first we need to delete a record from child table.
But if I delete a record from Person table it will automatically delete a record in Customer table and all records related to customer table in Order table would also be deleted.

Q:
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You create a new form in a project.
You need to display tabs in a vertical alignment.
Solution: Apply the Simple List pattern.
Does the solution meet the goal?

A. Yes
B. No

Correct Option: B
Remarks:

Explanation:

No". The Simple List pattern doesn't have a slot for adding a tab, and trying to add a tab control will cause the form to no longer be compliant with the Simple List pattern, even though it still compiles.

Pattern have vertical tabs.

Q:
DRAG DROP -

Q:
A company has a cloud-based installation of Dynamics 365 Finance.
A user reports slow response times in the application when accessing the production environment.
You need to diagnose the performance issue by using the Environment monitoring tool.
Which two features of the Environment monitoring tool should you use? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

A. Health metrics
B. SQL insights
C. System diagnostics
D. Option A and B Only

Correct Option: D
Remarks:

Explanation:

AB: Environment monitoring is a simple way to access current activity on environments in your Finance and Operations apps implementation. By using the
Environment Monitoring and SQL Insights that come in a user-friendly dashboard, you can see measurements and diagnostics of your environment's health.
Within the Health metrics dashboard, some issues are reported directly to the Microsoft Service Engineering Team and some are mitigated immediately. If there are any concerns regarding performance, this is a good way to gain insight into potential issues.
All SQL performance tools in LCS are available under the SQL Insights tab on the Environment Monitoring page for a specific environment.
