SALESFORCE-PD1 Developer Fundamentals Practice Test 6 — 15 Questions

Question 1

Which TWO statements about SOSL (Salesforce Object Search Language) are true? Choose 2 options.

Accepted Answer

SOSL can query text across multiple standard and custom objects in a single query.. SOSL searches across multiple objects and returns lists of sObjects grouped by object type.

Answer

SOSL can only query a single object per statement.

Answer

SOSL queries support complex arithmetic calculations and grouping clauses.

Answer

SOSL queries are executed using the SELECT keyword.

Question 2

Which TWO methods are available on the Database class for performing DML operations with partial success capability? Choose 2 options.

Accepted Answer

Database.update(). Database.insert() and Database.update() accept an allOrNone boolean parameter allowing partial success.

Answer

Database.save()

Answer

Database.commit()

Answer

Database.persist()

Question 3

Which THREE tools or contexts can be used to execute Anonymous Apex code? Choose 3 options.

Accepted Answer

Salesforce CLI (sf apex run). Salesforce CLI (option A) can execute Anonymous Apex via the `sf apex run` command (or the older `sfdx force:apex:execute`), which sends the Apex source to the Tooling API's executeAnonymous endpoint and returns the debug log and compile/run results. The Developer Console (option C) includes an Execute Anonymous window (Debug > Open Execute Anonymous Window) that compiles and runs arbitrary Apex in the current org and shows the resulting log. Salesforce Extensions for Visual Studio Code (option D) provide an "SFDX: Execute Anonymous Apex with Editor Contents" command that runs the active Apex file against an authorized org through the same executeAnonymous mechanism. The Standard Page Layout Editor (option B) only arranges fields, buttons, and related lists on record pages and cannot run code, and Lightning App Builder (option E) is a declarative drag-and-drop tool for composing Lightning pages and components, not for executing Apex.

Answer

Standard Page Layout Editor

Answer

Lightning App Builder

Question 4

Which TWO collection interfaces or classes are provided in Apex? Choose 2 options.

Accepted Answer

Map. List and Map are core collection types in Apex.

Answer

Vector

Answer

Dictionary

Answer

Hashtable

Question 5

Which TWO statements about SOQL relationship queries are true? Choose 2 options.

Accepted Answer

Child-to-parent queries use dot notation (e.g., Account.Name).. Parent-to-child queries use subqueries in parentheses, and child-to-parent queries use dot notation.

Answer

SOQL supports traversing up to 10 levels of parent relationships.

Answer

Parent-to-child queries use dot notation on the parent object.

Answer

Child-to-parent queries require subqueries.

Question 6

Which THREE operations can cause an automatic roll back of an entire Apex transaction? Choose 3 options.

Accepted Answer

Exceeding a governor limit such as SOQL query count.. Option C is correct because exceeding a governor limit (such as the SOQL query count) throws a runtime exception that cannot be caught, and the platform rolls back the entire Apex transaction. Option D is correct because standard DML statements (and Database methods with allOrNone set to true) throw a DmlException on failure, and if that exception is unhandled it aborts and rolls back the whole transaction. Option E is correct because any unhandled exception propagating up the execution stack terminates the transaction and triggers an automatic rollback of all DML performed in it. Option A is not correct because catching a DmlException in a try-catch block lets execution continue, so the transaction is not automatically rolled back. Option B is not correct because Database.insert(records, false) uses allOrNone=false, allowing partial success without rolling back the entire transaction.

Answer

Catching a DmlException inside a try-catch block.

Answer

Executing Database.insert(records, false) with partial failure.

Question 7

Which TWO methods are used to inspect sObject field metadata dynamically in Apex? Choose 2 options.

Accepted Answer

Schema.getGlobalDescribe(). SObjectType.getDescribe() and Schema.getGlobalDescribe() are used for inspecting schema metadata.

Answer

System.describeFields()

Answer

Object.inspect()

Answer

Database.getMetadata()

Question 8

Which THREE design patterns or tools help ensure secure coding practices regarding CRUD and FLS in Apex? Choose 3 options.

Accepted Answer

Using Security.stripInaccessible() before upserting data.. Option A is correct because Security.stripInaccessible() programmatically removes fields the running user cannot create or update (based on CRUD/FLS) from sObjects before a DML operation such as upsert, preventing unauthorized field writes. Option B is correct because adding WITH SECURITY_ENFORCED to a SOQL query enforces field- and object-level security at query time, throwing an exception if the user lacks access to any referenced field or object. Option C is correct because explicit Schema describe checks like Schema.sObjectType.Account.fields.Name.isAccessible() (and isCreateable()/isUpdateable()) let developers enforce FLS/CRUD manually before reading or writing data. Option D is incorrect because declaring classes 'without sharing' bypasses record-level sharing and does nothing to enforce CRUD or FLS, weakening security. Option E is incorrect because LWC HTML rendering tags only affect client-side display and cannot enforce server-side CRUD/FLS in Apex.

Answer

Declaring every class with 'without sharing'.

Answer

Relying solely on Lightning Web Component HTML rendering tags.

Question 9

A developer needs to store a collection of Account IDs where duplicates are automatically prevented and lookups are extremely fast. Which collection type should the developer use?

Accepted Answer

Set<Id>. Sets in Apex store unique elements and provide very fast lookups by value using methods like contains().

Answer

Map<Id, Id>

Answer

Queue<Id>

Answer

List<Id>

Question 10

An Apex trigger needs to check whether the current user has read access to the 'AnnualRevenue' field on the Account object before performing a calculation. Which method should the developer use?

Accepted Answer

Schema.sObjectType.Account.fields.AnnualRevenue.getDescribe().isAccessible(). Schema.sObjectType.Account.fields.AnnualRevenue.getDescribe().isAccessible() checks field-level security for the current user in Apex.

Answer

User.hasReadAccess('Account', 'AnnualRevenue')

Answer

Account.AnnualRevenue.getDescribe().isAccessible()

Answer

System.checkFieldAccess(Account.class, 'AnnualRevenue', 'Read')

Question 11

A developer writes an Apex method that executes a SOQL query inside a for-loop over a list of 200 Account records. Which governor limit is most likely to be immediately breached?

Accepted Answer

Total number of SOQL queries issued. The synchronous limit for SOQL queries is 100 per transaction. Querying inside a loop over 200 records will exceed this limit.

Answer

Total heap size allocation

Answer

Maximum CPU time on Salesforce servers

Answer

Total number of records retrieved by SOQL queries

Question 12

An application uses a SOSL search to find records across multiple objects. Which return type must be used to capture the results in Apex?

Accepted Answer

List>. SOSL search queries return a List of Lists of SObjects (List>), because a single search can return results across multiple different sObject types.

Answer

Map<String, List<SObject>>

Answer

SearchResult[]

Answer

List<SObject>

Question 13

What is the primary purpose of the Model-View-Controller (MVC) design pattern implementation in Lightning Web Components (LWC)?

Accepted Answer

To separate data, user interface, and application logic into distinct components. MVC separates application data (Model), user interface (View), and business logic/event handling (Controller) to promote modularity and maintainability.

Answer

To convert Apex triggers into asynchronous jobs

Answer

To bypass Salesforce governor limits automatically

Answer

To enforce field-level security without writing code

Question 14

Which primitive data type in Apex can represent a specific point in time, including both date and time values?

Accepted Answer

Datetime. The Datetime data type represents both a date and a time in Apex.

Answer

Date

Answer

Time

Answer

Timestamp

Question 15

A developer is writing a trigger on the Contact object that needs to reference old field values during an update operation. In which trigger context variable are these previous values stored?

Accepted Answer

Trigger.old. Trigger.old contains a list of sObject records prior to the update or delete operation.

Answer

Trigger.new

Answer

Trigger.previousValues

Answer

Trigger.newMap
