2 / 22

  1. Why is it a best practice to create a specialization of the FileDocument and Image entities?: It allows for better security and property configuration based on purpose.
  2. What is the default value of the attribute DeleteAfterDownload?: false
  3. Where are the file(s) or image(s) stored by default?: On the file server located on the application server
  4. When it is better to place Indexes?: If there are more Read than Write actions.

4 / 22

  • Model the conversion
  • Extend domain model
  1. Why is it a best practice to redeploy your app after cleaning up the model?: You might be confronted with unexpected and/or complex sync behavior during a next deployment.
  2. What does the function reverse() do?: It changes the direction in which the association is queried.
  3. What is the best naming for a self-reference where the buddy is referenced by an apprentice?: Apprentice_Buddy
  4. What is the correct XPath to retrieve the goals of the buddy of an appren- tice?: [SoccerSquad.Goal_Player/SoccerSquad.Player/SoccerSquad.Apprentice_Buddy [reversed()] = '[%CurrentO- bject%]']
  5. When localize is set to No, the date displayed in the client is based on the:: UTC value
  6. Localizing a DateTime attribute has an effect on:: Client representation
  7. If both the App and User time zones are set, the value of

5 / 22 the localized DateTime attribute displayed in the client depends on:: The Client time zone

  1. Jane in the Amsterdam time zone [UTC +2] selects 07/11/2020 in a date picker for a non-localized attribute. What will be the value stored in the database?: - 07/11/2020 12:00 AM
  2. Nick in the Amsterdam time zone [UTC +2] selects 07/11/2020 in a date picker for a non-localized attribute. What will be the date value if Nick converts it to a string in a microflow using formatDateTime?: 07/11/2020 02:00 AM
  3. The Mendix Client is:: Built on a combination of HTML, CSS, and JavaScript and runs in your browser.
  4. Static resources in Mendix:: Include stylesheets transmitted in CSS format to the client.
  5. The Communication between the Mendix Runtime and Database Server:: In- cludes communication between the supported database servers using JDBC.
  6. What is NOT an advantage of using the database source option versus the XPath option?: The database source option can be used to specify constraints that span entities.

7 / 22

  1. Which of the following is NOT a benefit that XPath provides to the Mendix Platform?: XPath can be used to automatically generate pages and widgets to show data on.
  2. What does the following XPath query return? //Product [Order- Management.OrderLine_Product/OrderManagement.OrderLine /OrderMan- agement.OrderLine_Order != $Order]: All the products that are ordered at least once, but not on the attected order.
  3. This XPath query can be optimized as follows: [OrderManagement.Order- Line_Product /OrderManagement.Product/MinimalStock > 50] [OrderManage- ment.OrderLine_Product /OrderManagement.Product/Status = 'Active']]: [Order- Management.OrderLine_Product/OrderManagement.Product [MinimalStock > 50 and Status = 'Active'] ]
  4. The request as result of this XPath can be optimized as follows: [Order- Management.Stock_Product /OrderManagement.Product/Status = 'Deactivat- ed' or OrderManagement.Stock_Supplier /OrderManagement.Supplier/Active = false()]: The request can be optimized by splitting it into ditterent requests and joining the results.

8 / 22

  1. Which of the following statements is NOT an XPath best practice with regards to optimal performance?: Do not use XPath when you can use SQL instead.
  2. Consider a situation in which there is an entity called Request with an attribute status that has three values: Draft, Submitted, and Approved. There are three user roles: Administrator, Customer, and Employee. The Customer user role is granted the Customer module role. The only access rule configured is read/write access for the Customer with the XPath [Status = Draft] applied. What would a user with the Customer user role see on a page with a data grid without any additional XPath constraints?: All the requests in the Draft status.
  3. Consider the exact same situation as above. What would Admin users see?- : No results would be returned.
  4. Consider the same situation again. What would happen if you granted Admin users access to a page with the Request entity in Studio Pro?: Studio Pro would detect an error and prevent a deployment.
  5. How does the platform use entity access XPaths to enforce

10 / 22 Administrators are granted the ability to manage all user roles, and Teachers can manage users with the Student role. Which of the following statements is false?: Administrators and teachers can create teacher accounts.

  1. Let's say you want Teachers to be able to manage accounts for Students, but only the Students who are in their class. So, you grant Teachers the ability to manage users with the Student role in the app security menu. Will this be sufficient?: No, because teachers will have the ability to edit the accounts of any Student, not just their own.
  2. What is a benefit of assigning only one user role to each user?: Simplicity
  3. Which operation can be used to select a specific set of rows in a table?: Selection
  4. The Set Union operation combines two lists into one that contains:: one version of the objects from both lists
  5. What operation combines the data from two different entities into one table?: Cartesian product
  6. What does the Projection operation do?: It allows you to select attributes for all objects. Re-take Knowledge CheckNext

11 / 22

  1. What can you use a constrain function for?: To filter on strings and dates in XPath queries.
  2. Which of the queries below can be used to filter on dates two weekso in the past?: [%BeginOfCurrentDay%] - 2 * [%WeekLength%]
  3. One of your XPath queries that use the contains() function is not performing very well. What is the most likely root cause?: You are using the function on a string that is set to 'unlimited'.
  4. When using the 'and' operator:: The 'and' operator will give a ditterent result based on how you write the XPath query.
  5. The not() function:: Generates a slow query.
  6. Which statement best describes how you would retrieve all related objects in the most optimal way?: When comparing to a related entity, it is enough to stop at the association to get the most optimal query.
  7. When should you apply an index?: You should apply indexes on attributes that are used in searches when the performance of your app is not up to par.
  8. What is normalization?: The removal of duplicate data from your domain model.
  9. Why would you want to do normalization?: To remove duplicate data from your app so you can avoid insertion, update, and deletion anomalies.
  10. What is denormalization?: The duplication of information in several entities to

13 / 22

  1. : In the console
  2. What is the difference between log messages in Studio Pro and log messages in the Developer portal?: The log messages in the Developer Portal have a Source field.

  2. You want to add a log event to an error flow on your REST Call to indicate a weather API call failed in your Holiday Request application. Which level of logging should you use?: Warning, you can still continue but someone should look into why the REST call is failing and whether further action is needed.
  3. Which of the following is a valid Mendix token?: CurrentUser
  4. You are creating a microflow where you have a Change Object activity. The change is dependent on a lot of checks and decisions (but, whichever choice, the change always happens). What is the best way to model this microflow?: Use Decisions, but place them in a sub-microflow to determine what the new value should be, and then use the return value of that sub-microflow in the Change Object activity.
  5. You need to determine what day of the week it is. What is the easiest way to do this?: Use the formatDateTime function to achieve this.
  6. What is the best approach to retrieve an object over association, while also checking whether the association exists?: Use a decision

16 / 22 retrieve activities in the sub-microflow for data you already have available in the main microflow, check whether it can be passed along as an input parameter instead.

  • You make sure that there are no commits in the sub-microflow, since it is not good for your application to commit inside of a loop.
  • If the sub-microflow uses a return value, you check whether it is really needed.
  1. Your application contains a microflow that calls three sub- microflows. Each of these sub-microflows does a retrieve from the database on the same entity. Should you change this?: Yes, you should do the retrieve in the main microflow and then pass it along to the three sub-microflows as an input parameter.
  2. Which statement about rules is true?: A rule can only be called from within a decision.
  3. What is a good reason to use a sub microflow?: - To use it as a 'get or create' microflow.
  • To reuse the same bit of logic in multiple microflows.
