Cloud Kicks (CK) keeps track of its shoe inventory in Salesforce.
When an order's status is changed to Activated, the inventory for the ordered shoe is reduced. At that point, a SOAP web service on the CK website must be called so that the website is updated to display the correct inventory amount for the shoe.
What should an app builder use to communicate to the CK web service when a shoe's inventory has changed?

  1. After-Save Record-Triggered flow
  2. Before-Save Record-Triggered flow
  3. Process Builder
  4. Workflow rule

Answer(s): A

Explanation:

To communicate to the CK web service when a shoe's inventory has changed, an app builder should use an after-save record-triggered flow. An after-save record-triggered flow is a type of flow that runs after a record is saved and can perform actions such as updating related records, sending emails, calling external services, etc. An after-save record-triggered flow can use an Apex action to invoke a SOAP web service using a WSDL file.

Cloud Kicks asked the app builder to insert a list of 25,000 records using deduplication for the Race_Track__c customobject.
Which tool should be used?

  1. Import Wizard
  2. Lightning Object Creator
  3. Data Loader
  4. Schema Builder

Answer(s): C

Explanation:

Cloud Kicks needs to insert 25,000 records with deduplication for the Race_Track__c custom object.
Here's the reasoning for choosing Data Loader:
Data Loader: This is the appropriate tool for importing large volumes of data (up to 5 million records) into Salesforce. It also provides deduplication options through Salesforce's native matching rules or by implementing external checks. Data Loader is highly scalable, and for 25,000 records, it is well- suited because it can handle more than the Import Wizard's record limits.

Option A (Import Wizard): The Import Wizard is not a good choice here because it supports up to 50,000 records, which may seem acceptable. However, it is generally recommended for smaller data imports, and deduplication options are limited compared to what Data Loader offers. Additionally, for bulk operations like 25,000 records, Data Loader is more efficient and robust.


Reference:

Import Wizard Limitations
Option B (Lightning Object Creator): This tool is used to create custom objects from spreadsheets and is not designed for bulk data loading or deduplication. It's not appropriate for large data imports. Option D (Schema Builder): Schema Builder is a tool used to view and modify the structure of objects and fields in Salesforce, not for data import or deduplication purposes. In summary, Data Loader is the most appropriate tool for importing a large number of records with deduplication needs.

Ursa Major Solar is ramping up the sales team to meet increased demand. As part of the short ramp up for these new reps, the manager wants to provide a help guide to enable reps to easily get help where needed during the different sales processes.
Which solution should an app builder recommend?

  1. Flow
  2. Journey Builder
  3. Chatter Publisher
  4. Path

Answer(s): D

Users can see where they are in the process, update the stage and fields, and access resources such as tips and links. [Source]



Cloud Kicks works on an annual subscription model.
When a sale rep marks an opportunity as closed won, a new opportunity should automatically be created for the renewal. The contracts team works outside of salesforce but also needs to be notified about closed deals in order to initial the contract process with the customer.
Which automation solution would meet these requirements?

  1. Approval Process
  2. Outbound Message
  3. Validation Rule
  4. Record-triggered flow

Answer(s): D

Explanation:

A record-triggered flow can be used to automate actions when a record is created or updated. In this case, a record-triggered flow can be configured to create a new opportunity and send an email to the contracts team when an opportunity is marked as closed won.



An app builder has modified a Lightning record page for a case and has added an email button item to the page layout; however, users are unable to see the new item on the layout.
What are two potential reasons why users are unable to view the item on the Case Lightning record page?
Choose 2 answers

  1. The page layout includes the case feed component.
  2. The email button contains JavaScript.
  3. The case page layout also contains custom buttons.
  4. The page layout excludes the case feed component.

Answer(s): A,B

Explanation:

The email button item will not be visible on the Lightning record page if the page layout includes the case feed component or if the email button contains JavaScript. The case feed component replaces the standard buttons on the page layout with actions in the feed. The email button item will not work if it contains JavaScript because JavaScript buttons are not supported in Lightning Experience.
