Custom Settings are custom data sets that store org-wide, profile-specific, or user-specific data. Hierarchy custom settings allow different values by profile/user. List custom settings store static data accessible via SOQL or cached methods. Custom settings provide faster access than custom objects for configuration data. They're useful for application configuration and constants.

Question 6 Easy Mcq

✓ Correct ✗ Incorrect

What is created when an object does not have a master-detail relationship to another object?

An element rule.

A relationship rule.

A system rule.

A sharing rule.

Explanation:

When an object does not have a master-detail relationship to another object, a standard ID field is created automatically. This is a unique 15 or 18-character alphanumeric identifier that serves as the record's primary key. The ID is auto-generated upon record creation and remains constant throughout the record's lifecycle. Unlike master-detail relationships where the child record depends on the parent, standalone objects manage their own IDs independently.

Question 7 Easy Mcq

It changes the password to the specified value.

It sets the password to the initially assigned password.

None of the above

Explanation:

Bulkification means designing Apex to handle multiple records efficiently in single execution, avoiding per-record processing. Bulkified code uses collections, minimizes SOQL queries and DML operations, and processes records in batches. Non-bulkified code fails with governor limits when processing bulk data. Bulkification is essential for triggers, batch jobs, and any code processing multiple records.

queryMore() returns the records count of more than 500 while queryAll() also returns the records that have been deleted because of a merge or delete.

queryAll() returns the records when the Ids are not known while queryMore() returns the records with known Ids.

queryMore() returns the records when the Ids are not known while queryAll() returns the records with known Ids.

Explanation:

Apex Limits (Governor Limits) restrict resources consumed by Apex code. Limits include SOQL queries (100 synchronous), DML statements (150), CPU time (10 seconds), heap size (6MB), and more. Limits prevent resource monopolization in multi-tenant environment. Efficient code design respects limits. Exceeding limits throws exceptions.
