D: Developer and Developer Pro sandboxes have different storage limits. Developer Pro has a larger storage limit compared to a Developer sandbox.

Why not other options?

A: Bulk API does not bypass storage limits.

B: The Data Import Wizard is a web-based tool, not an application installed on your computer.

Why Lightning Pages?

The Lightning Component framework is designed for building responsive Lightning Pages.

Allows for dynamic and modular development.

Why Not Other Options?

A: Salesforce Classic does not support Lightning Components.

C: JavaScript buttons are replaced by Quick Actions in Lightning Experience.

D: While integrations are possible, the framework is not primarily used for integrations.

To create and manage scratch orgs in Salesforce DX, the Dev Hub must be enabled in your Salesforce production or Developer Edition org. Dev Hub acts as the central hub for managing scratch orgs.

Why Lookup on Account to Global Address?

An Account can reference a single default Global Address via a lookup field, allowing multiple Accounts to share the same address.

This is more efficient than the reverse (lookup on Global Address to Account), as Global Address is the parent in this relationship.

Avoiding Master-Detail:

Lookup relationships provide flexibility in this use case since Accounts and Global Addresses have independent lifecycles.

Example:Create a custom lookup field on Account referencing the Global Address object.

Comprehensive and Detailed Explanation From Exact Extract:

The lightning-input-field component automatically respects field-level security and permissions. When used within a lightning-record-edit-form, it ensures that the field is displayed as a currency input and follows user permissions (viewable/editable) for the Salary__c field.

Trigger.old in a before insert trigger:

TheTrigger.oldcontext variable contains the old version of the records being processed in the trigger.

In abefore inserttrigger, the records being processed are new and have no prior state in the database, soTrigger.oldisnull.

This behavior is specific to insert triggers because there is no "old" record to reference before the record is created.

Why is it null?

The Trigger.old variable is only populated for triggers that handle updates or deletions (e.g., before update, after update, before delete, after delete). For insert operations, no previous state of the record exists.

Why not the other options?

A. An empty list of sObjects:

This is incorrect because Trigger.old is not initialized as an empty list for insert triggers—it is simply null.

B. Undefined:

Trigger.old is defined in the trigger context, but it is null for insert operations. Undefined is not a valid Apex state.

D. A list of newly created sObjects without IDs:

This describes Trigger.new in abefore inserttrigger, not Trigger.old. Trigger.new contains the new records being inserted.

Tooling API:

The Tooling API provides programmatic access to manage tests and other metadata in the org.

It can execute test classes or methods remotely.

Developer Console:

The Developer Console is a built-in Salesforce tool to execute Apex tests, debug logs, and more.

Allows developers to execute tests interactively.

B. Metadata API: Used for managing metadata, not for running tests.

C. Bulk API: Used for data operations, not related to testing.

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.

CandDare incorrect because SOSL is faster for text searches, not SOQL.
