QUESTION 1
A company's engineering department is conducting a month-long test on the
scalability of an inhousedeveloped
software that requires a cluster of 100 or more servers. Which of the following
models is the best to use?
A. PaaS
B. SaaS
C. BaaS
D. laaS
Answer: D
Explanation:
Infrastructure as a Service (IaaS)is the best model for the scenario described
because it provides ondemand
access to compute, storage, and networking resources that are ideal for a
scalable server
cluster. IaaS allows the engineering team to rent infrastructure resources
without having to invest in
physical hardware, making it perfect for temporary or fluctuating workloads,
such as scalability testing.
Key Characteristics of IaaS:
Full control over the operating systems and applications running on the servers.
Flexible resource allocation to support high scalability.
Ideal for custom software testing where specific server configurations may be
needed.
Why not the other options?
PaaS (Platform as a Service):While PaaS is excellent for application development
and deployment, it
abstracts the infrastructure layer, which would limit the engineering team's
control over the cluster's configuration.
SaaS (Software as a Service):SaaS delivers fully managed applications, not
infrastructure or testing
environments. Its irrelevant for this use case.
BaaS (Backend as a Service):BaaS is tailored to mobile or web application
backend development,
providing APIs and pre-built services, not infrastructure for a server cluster.
Platform Developer Reference:
While this question is broader than Salesforce-specific concepts,
understandingIaaS vs. PaaSis
relevant when working with Salesforce development. For example:
Salesforce operates as aPaaS(e.g., Force.com platform), allowing developers to
build and deploy
applications without managing underlying servers.
Testing scalability and performance at an infrastructure level (as in the
question) would fall
underIaaSconcepts, which Salesforce developers might encounter when integrating
external services
or infrastructure like AWS, Azure, or Google Cloud.
This foundational knowledge complements your understanding of cloud services in
the Salesforce ecosystem.
QUESTION 2
What are three characteristics of change set deployments?
Choose 3 answers Sending a change set between two orgs requires a deployment
connection.
A. Change sets can deploy custom settings data.
B. Change sets can only be used between related organizations.
C. Deployment is done in a one-way, single transaction.
D. Sending a change set between two orgs requires a deployment connection.
E. Change sets can be used to transfer records.
Answer: B,C,D
Explanation:
Change sets can only be used between related organizations:
Change sets require a relationship between the source and target Salesforce
orgs, such as a
production org and its sandboxes. You cannot use change sets between unrelated
Salesforce orgs.
Reference:Salesforce Change Set Overview
Deployment is done in a one-way, single transaction:
When a change set is deployed, it is applied to the target org as a single
transaction. If there are any
errors in the deployment, the entire transaction is rolled back.
Reference:Apex Development Guide
Sending a change set between two orgs requires a deployment connection:
Before sending or deploying a change set, a deployment connection must be
established between
the source and target orgs. This connection is configured in the setup menu
under "Deployment Connections."
Reference:Trailhead: Deployment Connections
Incorrect Options:
A . Change sets can deploy custom settings data:
Change sets cannot deploy data, including custom settings data. They only move
metadata.
E . Change sets can be used to transfer records:
Records (data) are not supported by change sets; they only facilitate metadata
migration.
QUESTION 3
Universal Containers wants to ensure that all new leads created in the system
have a valid email
address. They have already created a validation rule to enforce this
requirement, but want to add an
additional layer of validation using automation.
What would be the best solution for this requirement?
A. Submit a REST API Callout with a JSON payload and validate the fields on a
third party system
B. Use a before-save Apex trigger on the Lead object to validate the email
address and display an error message if it is invalid
C. Use a custom Lightning Web component to make a callout to validate the fields
on a third party system.
D. Use an Approval Process to enforce the completion of a valid email address
using an outbound message action.
Answer: B
Explanation:
Before-save Apex Trigger:
This is the best solution because abefore-save triggerruns before the record is
saved to the database,
providing an opportunity to validate or modify the data.
In this case, the Apex trigger can validate the email address using a regular
expression or a thirdparty
API call to ensure the email address is valid. If the email is invalid, an error
message can be
displayed using addError().
Why not the other options?
A . Submit a REST API Callout with a JSON payload:
REST callouts are more complex and generally not recommended for simple
validation tasks like
email format validation. Additionally, callouts cannot be performed directly in
a before-save trigger.
C . Use a custom Lightning Web Component (LWC):
LWCs are primarily for UI interactions and should not be used to enforce data
validations that are server-side requirements.
D . Use an Approval Process:
Approval Processes are for managing the approval flow of records, not for
real-time validations. They cannot enforce email validation directly.

QUESTION 4
Which statement should be used to allow some of the records in a list of records
to be inserted if others fail to be inserted?
A. Database. insert (records, true)
B. insert records
C. insert (records, false)
D. Database. insert (records, false)
Answer: D
Explanation:
Database.insert(records, false):
The Database.insert() method with the allOrNone parameter set to false allows
for partial success.
If some records in the list fail due to validation rules, triggers, or other
errors, the method will still
attempt to insert the remaining valid records.
The false parameter ensures that records that fail will not roll back the
transaction for the others.
Why not the other options?
A . Database.insert(records, true):
The true parameter makes the operation transactional (all or none). If any
record fails, all records will roll back.
B . insert records:
The insert DML statement behaves like Database.insert(records, true) by default
and rolls back all
records if any error occurs.
C . insert(records, false):
This syntax is invalid in Apex.

QUESTION 5
A developer identifies the following triggers on the Expense _c object:
The triggers process before delete, before insert, and before update events
respectively.
Which two techniques should the developer implement to ensure trigger best
practices are followed?
Choose 2 answers
A. Unity all three triggers In a single trigger on the Expense__c object that
Includes all events.
B. Unify the before insert and before update triggers and use Flow for the
delete action.
C. Create helper classes to execute the appropriate logic when a record is
saved.
D. Maintain all three triggers on the Expense __c object, but move the Apex
logic out of the trigger definition.
Answer: A,C
Explanation:
A . Unify all three triggers in a single trigger on the Expense__c object that
includes all events:
Salesforce best practices recommend having only one trigger per object to avoid
redundancy and conflicts.
By combining all the events (before delete, before insert, and before update)
into a single trigger, the
developer can manage the logic in an organized and maintainable manner.
This also simplifies debugging and ensures that the trigger logic executes in a
predictable order.
C . Create helper classes to execute the appropriate logic when a record is
saved:
Using helper classes allows for a clean separation of concerns. The trigger
becomes a dispatcher that
delegates logic to dedicated classes.
For example, you can create methods like applyDefaultsToExpense(),
validateExpenseUpdate(), and
deleteExpense() in a helper class and invoke them from the trigger.
This improves reusability, readability, and testability of the code.
