Salesforce Updated PDI Exam Questions and Answers by teodora

Why Controller?

A custom controller allows:

Complex validation involving multiple objects.

Redirection to another Visualforce page upon success.

Controllers can implement custom save logic and redirect using PageReference.

Why Not Other Options?

A. Apex: Apex is the underlying programming language, but a controller specifically handles the Visualforce logic.

B. Trigger: Triggers execute on DML events, not on button clicks in Visualforce.

D. Extension: Extensions enhance standard controllers but are not necessary here since a custom controller is being built.

References:

SOSL:

Designed for full-text searches, making it faster for unstructured or broad text searches across multiple objects.

Ideal for searching multiple fields simultaneously.

SOQL:

Optimized for structured queries where you need more control over filtering and relationships.

Can return up to 50,000 records in a single query, while SOSL returns only 2,000.

C and D are incorrect because SOSL is faster for text searches, not SOQL.

Why Not Other Options?References:

Scratch orgs are temporary, source-driven Salesforce environments used for development and testing. They allow developers to:

Work on independent features without interfering with each other's configurations.

Utilize a source-driven development model for CI/CD pipelines.

Salesforce CLI allows developers to automate deployments and run unit tests as part of a continuous integration (CI) pipeline. It is the most efficient tool for scripting these processes.
