NEW QUESTION # 121
A credit card company needs to implement the functionality for a service agent to process damaged or stolen credit cards. When the customers call in, the service agent must gather many pieces of information. A developer is tasked to implement this functionality.
What should the developer use to satisfy this requirement in the most efficient manner?

  • A. Apex trigger
  • B. Screen-based flow
  • C. Lightning Component
  • D. Approval process

Answer: B

Explanation:
The requirement is for service agents to gather many pieces of information when processing damaged or stolen credit cards.
Option A: Screen-based Flow
Correct Answer.
A Screen Flow allows developers to build guided, interactive forms that collect information from users.
Flows can have multiple screens, validation rules, and branching logic.
They can be created declaratively without code, making them efficient to implement.
Benefits:
Efficient Development: No need for code.
User-Friendly: Provides a step-by-step interface.
Maintainable: Easy to update as requirements change.
Building a custom Lightning Component requires development effort.
For simple data collection, a Flow is more efficient.
Option C: Approval Process
Incorrect.
Approval Processes are used for routing records for approval, not for gathering information from users.
Option D: Apex Trigger
Incorrect.
Triggers run in the background and are not used for interactive user interfaces.
Conclusion:
The most efficient way to satisfy the requirement is to use a Screen-based Flow, which is Option A.
Reference:
Build a Flow
Screen Flows
Incorrect Options:
Option B: Lightning Component
*Possible but Less Efficient.


NEW QUESTION # 122
A developer wants to import 500 Opportunity records into a sandbox. Why should the developer choose to use data Loader instead of Data Import Wizard?

  • A. Data Loader automatically relates Opportunities to Accounts.
  • B. Data Import Wizard does not support Opportunities.
  • C. Data Loader runs from the developer's browser.
  • D. Data Import Wizard cannot import all 500 records.

Answer: D

Explanation:
The developer should choose to use Data Loader instead of Data Import Wizard because Data Import Wizard cannot import more than 250 records at a time. Data Loader is a client application that can import up to five million records at a time, using either the user interface or the command line. Data Loader can also perform more complex operations, such as upsert, delete, and export. Data Import Wizard is a web-based tool that can import up to 50,000 records per file, but only 250 records per batch. Data Import Wizard can also perform insert, update, and upsert operations, but not delete or export. Data Loader does not run from the developer's browser, but rather from the developer's machine. Data Import Wizard does support Opportunities, as well as other standard and custom objects. Data Loader does not automatically relate Opportunities to Accounts, but rather requires the developer to map the fields accordingly. References:
