Explanation:

Declarative development uses point-and-click tools, while programmatic uses code. Key differences include setup, limits, and testing.

Correct Answers:

C. Declarative development can be done using the setup menu.
→ Configured via clicks (no code) in Salesforce Setup (e.g., Flows, Validation Rules).

D. Declarative development does not require Apex test classes.
→ Unlike Apex, no test coverage needed for deployment.

Why Others Are Wrong?

A: Declarative logic still requires maintenance (e.g., updates when fields change).
B: Declarative tools often have lower limits (e.g., Flow transaction limits).

Explanation:

When working with Apex triggers, developers must understand that a trigger can execute multiple times during a single transaction. This happens due to various factors such as recursive execution caused by workflow field updates, flows, and additional DML operations occurring within the same transaction.

In this scenario:

Workflow field updates can modify record values, which may re-trigger validation rules and other workflows.

Flows can cause additional updates that might also trigger the same Apex code again.

Triggers execute at different points in the transaction lifecycle, meaning multiple executions can occur based on record modifications.

This recursive behavior is essential for developers to anticipate while writing and testing trigger logic. To prevent infinite loops, developers often use techniques such as:

Static variables to track execution status.

Trigger context variables (e.g., Trigger.isUpdate, Trigger.isInsert) to control execution flow.

Explanation:

Since the Lightning component uses a wired property, the Apex method must:

✅ Be cacheable → cacheable=true ensures improved performance by allowing the Lightning framework to store and reuse data without unnecessary Apex calls.
✅ Be static → Wired properties expect static methods that do not rely on instance-specific data.
✅ Return a List of Opportunities → Since searchResults stores a list of Opportunity records, the method must return List rather than a generic List.

Explanation:

Let’s break down the code execution step-by-step:

Initialization:

Integer x = 0; // x starts at 0

First Loop Iteration:

x = 1: Assigns x the value 1.

x++: Increments x to 2.

while (x < 1): Checks if 2 < 1 → false → loop exits.

Final Value:

System.debug(x); // Outputs: 2

Explanation:

1️⃣ SOSL is faster for text searches (C)

SOSL searches across multiple objects and fields in a single query, making it more efficient for text-based searches.
It scans indexed fields quickly, making it ideal for searching Name, Description, and Comments fields in large datasets.
Best for keyword searches, such as finding records containing a specific phrase.

2️⃣ SOQL is able to return more records (D)

SOQL retrieves a larger result set, allowing up to 50,000 records per query, while SOSL returns only the first 200 records per object.
SOQL is best when searching structured data with filtering, such as retrieving Accounts based on specific criteria.
Ideal for querying specific fields from a single object, rather than searching text across multiple objects.
