A <dfn>custom controller</dfn> is an Apex class that implements all of the logic for a page without leveraging a standard controller. Use custom controllers when you want your Visualforce page to run entirely in system mode, which does not enforce the permissions and field-level security of the current user.

We should manually enforce the FLS and CRUD in the Apex Controller, or we should try to use Lightning Data service wherever possible because it takes care of FLS and CRUD for us.

Capture phase—The framework executes the capture phase from the application root to the source component until all components are traversed.
Bubble phase—The framework executes the bubble phase from the source component to the application root until all components are traversed or stopPropagation() is called.

[Deepak]

The handlers specified on each component are fired in this order i.e. from source to the owner. This phase where the event is handled from innermost to the outermost component is called the bubble phase.

Autolaunched Flow makes before-save updates to the new or changed record that launches the flow. Only these elements are supported: Assignment, Decision, Get Records, and Loop. A record-triggered flow runs only when a record is created or updated.

There are two ways for choosing the test distribution for A/B Test as follows:

1. How much is percentage of subscribers?
2. How many subscribers?

[Deepak]

The system randomly selects which subscribers receive test and remainder, allowing you to use the same set of subscribers for A/B tests in the future Send the winning version to the remainder of your subscribers automatically when the winner is determined or to come back and manually perform the send.

1. Create an outbound changeset.
2. Add the record types.
3. Click "Add/View" dependencies.
4. Add the required processes.

[Deepak]

Process Instance record is created every time for particular object record which is submitted for approval. It's also read-only object.

[Deepak]

We can not modify the record created in ProcessDefinition Object. But we can describe, query, search and retrieve the approval processes information.

[Deepak]

Yes, you can call batch apex from a apex trigger.

If a variable is designated as actionable, the model uses prescriptive analytics to suggest actions (improvements) the user can take to improve the predicted outcome.Einstein Discovery calculates model performance by comparing how closely predicted outcomes come to actual outcomes.

I think you can have 4 groupings in a Compare Table in Salesforce.

To export the ListViews, you can use Dataloader.IO[https://dataloader.io] and then select the Export Task and run this SOQL Query:
SELECT Id, Name, DeveloperName, NamespacePrefix, SobjectType, IsSoqlCompatible, CreatedDate, CreatedBy.Name, LastModifiedDate, LastModifiedBy.Name, LastViewedDate, LastReferencedDate,sharedTo FROM ListView
