Cosmic Lux is a company that uses Salesforce as the primary system to manage accounts. An ERP system is currently used to manage contact records of customers in Europe. The sales director of the company would like to store only the accounts associated with these contacts in Salesforce. To make the related contacts visible in Salesforce, Salesforce Connect should be used. The contacts in the ERP system have not been configured to store the Salesforce ID of the parent account record. A developer has been asked to show all the related contacts from the external system on the account detail page in Salesforce. Once Salesforce Connect has been configured, which relationship field should the developer define on the external object for this requirement?
Choose 1 answer.
A. Indirect Lookup
B. Internal Lookup
C. External Lookup
D. Lookup
Choose 1 answer.
✔️A. Indirect Lookup
B. Internal Lookup
C. External Lookup
D. Lookup
An indirect lookup relationship field can be used to link a child external object to a parent standard or custom object in Salesforce, such as the Account object. A custom unique, external ID field on the parent Account object can be selected to match against the child’s indirect lookup relationship field, whose values are determined by the specified External Column Name. Since the external system does not contain unique record identifiers for the account records from Salesforce, a custom External ID field needs to be used. That is why using an indirect lookup relationship is the only way of meeting this requirement.
A lookup relationship can only be used for this use case if the external object includes a column that identifies related Salesforce records by their 18-character IDs. An external lookup relationship links a child standard, custom, or external object to a parent external object. In this case, it is necessary to link a child external object to a parent standard object, so an external lookup relationship cannot be used. There is no relationship field called ‘Internal Lookup.

A. The Lightning Component Framework allows only Aura components to be added to Lightning tabs.
✔️B. My Domain needs to be deployed in order to add the components to Lightning pages and tabs.
C. Each Lightning web compoñent bundle must contain at least a controller and a CSS file.
D. Each Lightning web component must be wrapped in an Aura component before it can be added.
The Lightning Component Framework allows both Aura components and Lightning web components to be added to Lightning pages and tabs. However, My Domain needs to be deployed first before the components can be added to Lightning tabs, Lightning pages, as standalone apps, as actions and action overrides, as custom Lightning page templates, or elsewhere in the org.
Each Lightning web component that renders Ul consists of an HTML file, a JavaScript file (controller), and a metadata configuration file. A Lightning web component does not need to be contained in an Aura component for it to be added to a page or as a tab.

C. MapeId, Schema. RecordTypeInfo> mapRecTypes result.getRecordTypes();
B.Map<Id, Schema. RecordTypeInfo> mapRecTypes result.getRecordTypeInfosById();
To return a map of the record ids and details of their associated record types, the getRecordTypeInfosById() method of the Schema DescribeSObjectResult class can be used. The data type used to store the results of this method is a map collection in which the key is an id and the value is the Schema. Record TypeInfo class.
A The ‘getRecord TypeInfos’ method returns a list of the record types, but since line 6 contains code that uses the get() method, a method that returns a map should be used. There are no methods called getRecord Types’ and ‘getRecordTypelds

A. All customizations are specified as metadata, allowing for easy upgrades
B. All customers share the same code base, but have their own database
C. Metadata includes configuration but not code
D. Automatic upgrades are applied during the year according to the Salesforce release schedule to all customers
Choose 2 answers.
✔️A. All customizations are specified as metadata, allowing for easy upgrades
✔️D. Automatic upgrades are applied during the year according to the Salesforce release schedule to all customers
All standard and custom configurations, functionality, and code in an org are metadata. These customizations are separated in a special metadata layer, so upgrades can easily be performed. These uprcades are released automatically three times a year for all customers.
In Salesforce’s multitenant environment, users share the same code base and database. Hence, governor limits are strictly imposed.

Cosmic Solutions has a custom object called Weekly Employee Summary, which stores a summary of employee data that is tracked in Salesforce, such as hours worked and wage totals. An autolaunched flow has been built to calculate this information and create a new Weekly Employee Summary record for each employee every time it is run. Currently, a Salesforce Administrator needs to run this flow manually once a week. They would like this type of operation to be run automatically in the future. Which solutions would meet this requirement?
Choose 2 answers
A. Invoke the flow from a schedule-triggered flow.
B. Invoke the flow from an Apex job that runs weekly.
C. Configure the flow on the ‘Scheduled Jobs’ page in Setup.
D. Use an existing Process Builder process to run the flow weekly.
✔️A. Invoke the flow from a schedule-triggered flow.
✔️B. Invoke the flow from an Apex job that runs weekly.
A declarative solution is to invoke the autolaunched flow from a schedule-triggered flow using the Subflow element in Flow Builder. Schedule-triggered flows can be configured to start on a specified date and time, with several frequency options. The scheduling configuration is available on the flow’s Start element. The Subflow element is added that references the autolaunched flow to invoke.
A programmatic solution is to invoke the flow from an Apex class that implements the Schedulable interface, which enables the Apex class to run on a scheduled basis. To invoke a flow from Apex, the Flow.Interview class is used.
Process Builder cannot be used to invoke autolaunched flows in scheduled intervals or timings. An auto-launched flow cannot be configured on the ‘Scheduled Jobs’ page in Setup.

A developer is required to ensure that a reason is entered if an opportunity stage is updated to ‘Closed Lost. What is the best way to meet this requirement?
Choose 1 answer.
A. Required field
B. Apex trigger
C. Validation rule
D. Formula field
C. Validation rule
A validation rule can be used to check both the stage and reason fields of an opportunity during the update. If the stage is set to ‘Closed Lost’ and the reason field is empty, then the validation rule can display the wror message.
The requirement can be met using a declarative tool, so there is no need to use an Apex trigger. A formula field is used for displaying values, for example, based on data from the current record or related records. Setting the field to ‘Required’ will require that field to be always populated regardless of the opportunity stage.

What is true regarding accessing sharing programmatically?
Choose 3 answers.
A. Objects on the detail side of a master-detail relationship do not have a sharing object
B. Programmatic sharing can only give record access to one individual user at a time
C. CustomObject_Share is the sharing object for a custom object
D. Account__Share is the sharing object for the Account object
E. AccountShare is the sharing object for the Account object
✔️A. Objects on the detail side of a master-detail relationship do not have a sharing object
✔️C. CustomObject_Share is the sharing object for a custom object
✔️E. AccountShare is the sharing object for the Account object
To access sharing programmatically, the sharing object associated with the standard or custom object should be used.
To determine the name of the share object associated with a standard object, the suffix “Share” is added to its name. For example, the share objects for the Account, Case, and Contact objects are AccountShare, CaseShare, and ContactShare respectively. As for custom objects, the Share” suffix is used instead. For example, the sharing object for MyCustomObject (or MyCustomObject_c) is MyCustomObject_Share.
Objects on the detail side of a master-detail relationship do not have an associated sharing object, and access to the detail records is determined by the master object sharing object and the sharing setting of the relationship.
Record access can be granted to users or groups with programmatic sharing.

There is a requirement to rate all accounts daily based on the values of the opportunities closed in the current year, the number of open opportunities, and the opportunity close rates. The account with the highest aggregated result should be rated number 1, and so on until the account with the lowest rating is updated. How could this requirement be achieved?
Choose 1 answer.
A. Use an Apex trigger on the Account object and schedule it to run each night.
B. Use a Batch Apex job and schedule it to run each night.
C. Use a platform event-triggered flow to run scheduled nightly updates.
D. Use Process Builder and schedule an action to run each night to sort and rate accounts.
✔️B. Use a Batch Apex job and schedule it to run each night.
Processes or triggers cannot be configured to run periodically at fixed timings or intervals. A scheduled Apex job would be suitable for this requirement since it can be scheduled to run at regular intervals and is very capable of performing the required logic. Platform event-triggered flows cannot be scheduled. A scheduled flow may also be used in the above scenario, but if the logic is too complex, Apex should be used. Furthermore, batch Apex has much higher governor limits compared to scheduled flows.
A batch Apex job can be used to process all the account records daily. An Apex class that implements the ‘Database.Batchable’ interface can be created for the batch Apex job. Another Apex class
that implements the ‘Schedulable’ interface can be created to execute the batch Apex job at regular intervals.
The ‘Schedule Apex’ page in the Salesforce user interface or the ‘System.schedule’ method can be used to specify the schedule. The Apex class defined for the batch Apex job must use the following syntax:
