Salesforce Authenticator is an app that adds an extra layer of security for logging into Salesforce by requiring users to verify their identity using their mobile device after entering their username and password on Salesforce login page. To see how many users have successfully used Salesforce Authenticator since it was rolled out, an administrator can use two methods:
A) Create a new view In Identity Verification History, specifying Method.
Identity Verification History is a tool that shows information about each identity verification event for users in your org, such as the date and time, the verification method used, the IP address, and the status of the verification. By creating a new view in Identity Verification History and specifying the method as Salesforce Authenticator, an administrator can see how many users have used the app to verify their identity when logging in.

Login History is a tool that shows information about each login attempt for users in your org, such as the date and time, the username, the source IP address, the login type, and the status of the login. By exporting Login History as a CSV file and filtering based on the Authentication Method Reference column, an administrator can see how many users have used Salesforce Authenticator as their authentication method when logging in.

A junction object is a custom object that has two master-detail relationships with two other objects. A junction object allows administrators to create many-to-many relationships between objects, such as relating multiple accounts to multiple regions.
To create a junction object called Account Region to link the standard Account object with a custom object called Region, an administrator needs to do the following steps:
A) Make a master-detail relationship field on the junction object to the Region object.
A master-detail relationship field is a field that links a child record to a parent record. The child record inherits the sharing and security settings of the parent record. By making a master-detail relationship field on the junction object to the Region object, an administrator can link each Account Region record to one Region record and make Region the first master of the junction object. Reference: https://help.salesforce.com/s/articleView?id=sf.relationships_considerations.htm&type=5 D) Configure a master-detail relationship field on the junction object to the Account object.
By configuring a master-detail relationship field on the junction object to the Account object, an administrator can link each Account Region record to one Account record and make Account the second master of the junction object. This allows administrators to relate multiple accounts to multiple regions through the junction object.

As explained in question 4, record types allow administrators to offer different business processes, picklist values, and page layouts to different users based on their profiles. By using separate record types for rental and real estate opportunities, DreamHouse Realty can capture different client information on their opportunities using custom page layouts for each record type. The record types can also determine which sales processes and paths are available for each opportunity type.

To automate the renewal process for service plans, AW Computing should configure a flow that will create the renewal based on the closed-won date and opportunity line items. A flow is a tool that can automate complex business processes by executing logic, interacting with Salesforce database, calling Apex classes, and guiding users through screens. A flow can be triggered by various events, such as when an opportunity is closed won. Reference: https://help.salesforce.com/s/articleView?id=sf.flow_overview.htm&type=

To make sure that the changes are in production, you need to add the components to an outbound change set and deploy it to production. A change set is a tool that allows you to send customizations from one Salesforce org to another. A change set can contain components such as objects, fields, profiles, permission sets, workflows, and more. You can use change sets to migrate changes from a sandbox org to a production org or between two sandbox orgs that are affiliated with the same production org. In this case, you need to add the master-detail field and all the affected profiles to an outbound change set in your sandbox org and then deploy it to your production org.
