Nickname__c is a custom text field on a contact record that is utilized to override the contact's name appearing on an email template. This field is not required and is not always filled in.
Which formula should an app builder use to select the contact's preferred name for email communications?

  1. IF(NOT(ISBLANK(Nickname__c)), Nickname_c,FirstName)
  2. IF(TEXT(Nfckname__c), Nickname_c,FirstName)
  3. IF (ISNUUL(Nteknarne _..c),Nicknamec,Firstftame)
  4. IF(NOT(BLANKVALUE(Nickname__c)), Nickname__c, FirstName)

Answer(s): D

Explanation:

The formula that should be used to select the contact's preferred name for email communications is IF(NOT(BLANKVALUE(Nickname__c)),Nickname__c, FirstName). This formula checks if the Nickname__c field is blank or null, and if not, it returns the value of the Nickname__c field. Otherwise, it returns the value of the FirstName field.



Universal containers (uc) want to delete data in several fields for 5000 lead records. UC export the selected record IDs and fields that need to have data deleted in a csv file.
Which two steps should an app builder suggest to meet these requirements? Choose 2 answers

  1. Select the correct record type
  2. Use import Wizard to update leads using the CSV file
  3. Select insert null values in settings.
  4. Use Data Loader to update leads using the CSV file

Answer(s): C,D

Explanation:

The two steps that should be suggested to meet these requirements are to select insert null values in settings and to use Data Loader to update leads using the CSV file. Selecting insert null values in settings will allow Data Loader to overwrite existing values with null values. Data Loader is a tool that can import, export, update, or delete large amounts of data.



Universal Containers (UC) has a custom Invoice object and a custom Invoice Line Item object. TTie

Invoice Line-Item object has a lookup relationship to the Invoice. UC would like to convert the lookup relationship to a master-detail relationship but is unable to do so.
Which two reasons could be preventing this relationship conversion? Choose 2 answers

  1. Custom objects are unable to be on the detail side of a master-detail relationship.
  2. There are already two master-detail relationships on the Invoice Line Item.
  3. Invoice Line-Item records exist without having the Invoice lookup field populated.
  4. There is a roll-up summary field on the Invoice object.

Answer(s): B,C

Explanation:

The two reasons that could be preventing this relationship conversion are that there are already two master-detail relationships on the Invoice Line Item and that Invoice Line Item records exist without having the Invoice lookup field populated. A custom object can have up to two master-detail relationships, so adding another one would exceed the limit. Also, a master-detail relationship requires that the detail records have a value in the master lookup field, so any records with a blank Invoice lookup field would prevent the conversion.



What are two reason to create an unmanaged package? Choose 2 answers

  1. Distributing open-source projects on the AppExchange.
  2. Publishing an application for sale on the AppExchange
  3. Deploying from a Developer Edition environment
  4. Distributing upgradeable components to another Salesforce org

Answer(s): A,C

Explanation:

The two reasons to create an unmanaged package are to distribute open-source projects on the

AppExchange and to deploy from a Developer Edition environment. An unmanaged package is a collection of components that can be installed in any Salesforce org but cannot be upgraded or controlled by the developer. An unmanaged package can be used to share open-source projects or to deploy components from a Developer Edition environment to another org.



Universal Containers is adding drone delivery to service offerings, and the developer has written and tested code prior to deployment to production, and the change set is ready to go. The deployment window will occur when the developer is on vacation.
What can the app builder do to ensure a smooth deployment to production?

  1. Remove Apex classes from Abound change set.
  2. Validate the inbound change set.
  3. Use a metadata package set.
  4. Validate the outbound change set.

Answer(s): B

Explanation:

The app builder should validate the inbound change set to ensure a smooth deployment to production. Validating an inbound change set allows the app builder to test whether the change set can be deployed without errors in the target org. Validating an inbound change set does not affect any data or metadata in the target org.
