Salesforce PDI Exam Dumps

The@RestResourceannotation exposes an Apex class as a RESTful web service. TheurlMappingparameter defines the endpoint's URL.

Incorrect Options:

A:@RemoteActionis used for JavaScript remoting.

C:@HttpInvocableis used for invocable methods, not REST services.

D:@AuraEnabledis for enabling methods in Aura components or LWC, not REST services.

Public Method (A):The parent component can call a public method defined in the child component to pass data directly.

Public Property (B):The parent component can bind data to a public property in the child component using the attribute syntax.

Incorrect Options:

C:Apex controllers are not used for direct communication between parent and child components.

D:Custom events are used for communication from child to parent, not parent to child.

To meet the requirements:

For mobile devices, the content should display inthree rows.

For desktops and tablets, the content should display ina single row.

Explanation of Correct Option (B):The code useslightning:layoutItemwith appropriate sizing formediumDeviceSize='4', which ensures:

Mobile devices: Each layout item will occupy the full width (size='12'), resulting in three rows.

Tablets and desktops: Each layout item will occupy one-third of the row (mediumDeviceSize='4'), displaying in a single row.

Example Code from Option B:

<lightning:layoutmultipleRows='true'>

<lightning:layoutItemsize='12'mediumDeviceSize='4'>{!v.account.Name}</lightning:layoutItem>

<lightning:layoutItemsize='12'mediumDeviceSize='4'>{!v.account.AccountNumber}</lightning:layoutItem>

<lightning:layoutItemsize='12'mediumDeviceSize='4'>{!v.account.Industry}</lightning:layoutItem>

</lightning:layout>

Option A:Does not account for mediumDeviceSize and will not adjust for tablets/desktops.

Option C:Uses incorrect sizing formediumDeviceSize, which may not display correctly for tablets/desktops.

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.

Why External ID?

The Order Number is used to identify records uniquely, both in Salesforce and in external systems.

Marking it as anExternal IDensures it can be matched or referenced during data imports and integrations.

Why Unique?

Setting the field as Unique ensures that duplicate values are not allowed for the Order Number.

Why Not Other Options?

A . Indirect Lookup: Used for external object relationships, which is not applicable here.

B . Direct Lookup: Not relevant for unique field identification.

D . Lookup: Used for creating relationships, not for identifying unique fields.
