Salesforce Telephonic Interview Questions with Answers

1. What is Apex?

Ans: It is the in-house technology of salesforce.com which is similar to Java programming with object oriented concepts and to write our own custom logic.

2. What is S-Control ?

Ans: S-Controls are the predominant salesforce.com widgets which are completely based on JavaScript. These are hosted by Salesforce but executed at client side. S-Controls are superseded by Visualforce now.

3. What is a Visual force Page?

Ans: Visual force is the new markup language from Salesforce, by using which, we can render the standard styles of Salesforce. We can still use HTML here in Visual force. Each visualforce tag always begins with “apex” namespace. All the design part can be accomplished by using Visualforce Markup Language and the business logic can be written in custom controllers associated with the Page.

4. Will Visual force still supports the merge fields usage like S-control ?

Ans: Yes. Just like S-Controls, Visualforce Pages support embedded merge fields, like the {!$User.FirstName} used in the example.

5. Where to write Visualforce code?

Ans: You can write the code basically in 3 ways.

setup->App Setup->Develop->Pages and create new Visulaforce page.

Setup -> My Personal Information -> Personal Information -> Edit check the checkbox development mode. When you run the page like this, https://ap1.salesforce.com/apex/MyTestPage. you will find the Page editor at the bottom of the page. You can write you page as well as the controller class associated with it, there it self.

Using EclipseIDE you can create the Visulaforce page and write the code.

6. What are Apex Governor Limits?

Governor limits are runtime limits enforced by the Apex runtime engine. Because Apex runs in a shared, multitenant environment, the Apex runtime engine strictly enforces a number of limits to ensure that code does not monopolize shared resources. Types of limits that Apex enforces are resources like memory, database resources, number of script statements to avoid infinite loops, and number of records being processed. If code exceeds a limit, the associated governor issues a runtime exception.

7. Difference between Sandbox and Development environment?

environment for salesforce.com is crucial to change control. Salesforce.com provides the tools needed to test anything in a test environment before you implement it in your live instance. You can either test in a Sandbox environment or in a Developer environment. What is the difference? I will share what I know…

Sandbox

The salesforce.com Sandbox environment is an exact copy of your salesforce.com instance. You can copy your live instance to a sandbox environment (but you have to perform manually from sandbox to developer edition) where you can test any changes, implementations, AppExchange apps or updates. It can also be your hands-on training environment without risking your live data.

You can either copy your configuration and data into a sandbox environment or just the configuration. It acts exactly like your live instance, but be careful if you have workflow rules or automations because they will work in the sandbox as well.

I know that this sounds wonderful and if you don’t have it, you are dying to know how to get it. The problem is the cost. If you are on Unlimited Edition, then cost is not a problem because it comes included. But for Enterprise, Professional or Group Editions, you have to pay… and the price is hefty; anywhere between 25k-50k per year. For a lot of companies, that is more than they are paying for their live salesforce.com instance. So how do you test salesforce.com without Sandbox?  It is always suggested to develop application in sandbox instance then go for LIVE.

Developer Edition

Developer Edition was an edition created for development of integrations and apps, specifically for the AppExchange. It is also a great tool for testing/training in salesforce.com. What makes this a great tool is the fact that it is free. Anyone can get a Developer Edition of salesforce.com. It is a standard Enterprise Edition with very limited storage space. You cannot copy your configuration or data onto the Developer Edition, but you can customize it to match your instance’s look and feel. Once it is customized, you can use it for training, testing or anything else you want. It takes a little bit of work, but you can make it act and feel just like your live instance. The work is well worth it for the free price.

To get a copy of Developer Edition for yourself or your company go here. Play around with it. Get apps from the AppExchange. Do anything and everything that you have been scared to do your live system. If you come up with a clever way of using the system, post it on AppExchange and share your knowledge.

8. How to schedule export or take the backup of salesforce?

Salesforce allows you to obtain a copy of all your data using the data export feature.  You can generate backup files manually once every six days or schedule them to generate automatically at weekly or monthly intervals.  The backup file will come to you in the form a zip file that contains all of your organization’s data in a set of CSV (comma-separated values) files.  If you do not see the data export feature, contact salesforce.com to have the Data Export Service activated.

Step by Step Instruction:

Click Setup >Data Management > Data Export > Schedule Export.

Select the desired encoding for your export file. Leaving the default is fine.

Check the Include in export checkbox if you want to include attachments in the export (optional)

Leave the default Replace carriage returns with spaces if you want your export files to have spaces instead of carriage returns.

Select Weekly as the the frequency for the exports.

Choose start and end dates. Set the end date to sometime in the distant future such as 20 years from the begin date.

Set the time of day for your scheduled export. The export is put in a job queue and the exact time of the export will depend on the amount of activity in the queue.

You can select the types of data to include in your export. It is best to include all data in your export file. This will make sure all your organizations data is exported.

Click Save.

Points to Remember:

Formula and roll-up summary fields are never included in exports.

Articles are not included from exports.

The export notification email is sent to the email address on file for the user who created the scheduled export. There is no way to indicate another email address. If as an Administrator you want the email to go to another person, have them grant you login access, login as them and schedule the data export.

Important:

Scheduled backup exports of your data is limited to weekly exports.

You have 48 hours from the time you are notifiedthe backup is available to download the backup file.

The email notification for backups goes to the email address in Salesforce of the person logged in who schedules the backup

10. Do governor limits apply to sandbox instances?

Ans : Governor limits do apply to all Salesforce instances (trial, developer, production or sandbox environments). However code coverage and successful execution of test classes is only enforced when deploying to a production environment.
