Frequently Asked Informatica Cloud Interview Questions and Answers

1. What is one of the biggest problems that Informatica cloud is solving?

One of the biggest problems solved by the Informatica cloud is the “data integration” problem. This problem generally occurs when you try to move your data from the legacy architecture to the cloud-based architecture.

2. What is data integration?

Data integration is a general industry term used to combine the data from various business systems into one unified view. This unified view is stored in a data warehouse.


Let us take the example of CourseDrill that provides online IT training and education, where different students can opt for various courses. CourseDrill uses a lot of tools to execute its operations & some of them are:

  • Google ads and Facebook ads to promote and get new customers.
  • Google Analytics to track its website performance.
  • Database to store all the user information.
  • Email marketing to send marketing emails to nourish leads.

Each of these tools has a piece of information regarding CourseDrill operations. But to get a complete view of the business, we need to combine the data into one place. This process of combining all the data in one place is called data integration.

The Informatica cloud is a lightweight program that is installed & configured on top of a server. This helps in establishing connectivity between on-premises and the cloud and supports data exchange between these two. The secure agent provides a secure environment to process data locally. The Informatica cloud eliminates the manual interaction by automatically updating and restarting the secure agent software. This helps organizations in focusing on developing applications without worrying about administration.

The secure agent majorly executes the following services on the server:

  • Data integration service
  • Process integration services
  • Executes batch commands or shell scripts in a command flow.

5. How to start a secure agent in the Informatica cloud?

We can do it in five simple steps that are mentioned below:

Open the service panel by navigating:

  1. To your start menu(you can find the start menu in the bottom left of your computer screen).

  3. Open administrative tools.
  4. Open services menu.
  5. Once you open the services menu, right-click to start, stop and Restart the service.

6. List any three different types of transformations in the cloud designer?

Three different transformations in the cloud designer are:

  1. Expression Transformation: The row-level calculations are done by the expression transformation.
  2. Filter Transformation: Filter transformation can filter out the data in the flow itself.
  3. Joiner Transformation: As the name suggests, the joins can be created by the joiner transformation.

7. What is mapping in the Informatica cloud?

Mapping is nothing but a group of objects that are linked together by a group of transformations. These transformations contain protocols that define data flow and how the data is loaded within the targets.

8. List the basic components of Mapping?

The basic components of Mapping are:

  1. Mapping variables and parameters
  2. Source tables
  3. Mapping transformations
  4. Target objects 

9. What do you know about the Runtime environment?

Run time environment is an execution platform used to run the application integration tasks and data integration tasks. Every organization must consist of at least one Run time environment so that users can run their tasks.

10. List the different mapping areas of cloud designers?

There are five different mapping areas of cloud designer they are:

  1. Mapping Canvas
  2. Transformation Palette
  3. Properties Panel
  4. Toolbar
  5. Status Area

11. What is the use or Replication task?

By using the Replication task, we can create the exact duplicate of data within a database table and send it to the desired target.

There are three different types of operations you can choose when you are performing the replication task they are:

  1. Incremental load after initial full load.
  2. Incremental load after initial partial load.
  3. Full load each run.

12. Differentiate between synchronization task and replication task?

There are three main differences between the synchronization task and the replication task.

Synchronization Task

Replication Task

In the synchronization task, we must contain a target to integrate the data.

The replication task itself creates a target.

It is not possible to replicate the complete schema and the tables in it at a time.

It is possible to replicate the entire schema and the tables in it.

The user needs to manage the incremental data processing in the synchronization task. 

A Replication task arrives with a built-in incremental processing mechanism.

13. List the different Use Cases in the Informatica cloud?

There are five different use cases in the Informatica cloud they are:

  1. Data synchronization
