1. Can two users have the same profile? Can two profiles be assigned to an equivalent user?

Profiles determine the extent of access a user can have during a Salesforce org.

As far as the first part of the question is concerned, Yes. One profile can be assigned to any number of users. Take the instance of a Sales or Service team during a company. The entire team are going to be assigned an equivalent profile. The admin can create one profile: Sales Profile, which can have access to the Leads, Opportunities, Campaigns, Contacts and other objects deemed necessary by the corporate .

In this way, many users are often assigned an equivalent profile. In case the team lead or manager need access to additional records/ objects then it are often done by assigning permission sets just for those users.

To make sure no single client monopolizes the shared resources, Salesforce introduced the concept of Governor Limits which is strictly enforced by the Apex run-time engine.

Governor Limits are a Salesforce developer’s biggest challenge. That is because if the Apex code ever exceeds the limit, the expected governor issues a run-time exception that can't be handled. Hence as a Salesforce developer, you've got to be very careful while developing your application.

Different Governor Limits in Salesforce are:

Per-Transaction Apex Limits

Force.com Platform Apex Limits

Static Apex Limits

Size-Specific Apex Limits

Miscellaneous Apex Limits

Email Limits

Push Notification Limits

3. What is a sandbox org? What are the various sorts of sandboxes in Salesforce?

A sandbox may be a copy of the assembly environment/ org, used for testing and development purposes. It’s useful because it allows development on Apex programming without disturbing the assembly environment.

When can you use it?

You can use it once you want to check a newly developed Force.com application or Visualforce page. You can develop and test it within the Sandbox org rather than doing it directly in production.

This way, you'll develop the appliance with none hassle then migrate the metadata and data (if applicable) to the assembly environment. Doing this during a non-production environment allows developers to freely test and experiment applications end to finish .

Types of Sandboxes are:

Developer

Developer Pro

Partial Copy

Full

4. are you able to edit an apex trigger/ apex class in production environment? Can you edit a Visualforce page in production environment?

No, it's impossible to edit apex classes and triggers directly in production environment.

It must be done first in Developer edition or testing org or in Sandbox org. Then, to deploy it in production, a user with Author Apex permission must deploy the triggers and classes using deployment tools.

However, Visualforce pages are often created and edited in both sandbox and in production.

Only if the page has got to do something unique (different values), it might need to be developed via Sandbox.

5. What are the various data types that a typical field record name can have?

A standard field record name can have data sort of either auto number or text field with a limit of 80 chars.

For generating auto numbers, the format must be specified while defining the sector and then for each record that's added, the amount will get auto generated. For example:-

Sr No-{1}

Sr No-{2}

Sr No-{3}

6. Why are Visualforce pages served from a special domain?
