All these Informatica IICS interview questions and their Answers are presented here after thorough research. To simplify your preparation, this blog post will help you explore concept-wise questions and also be divided into the following three levels:

  • Basic IICS Informatica Interview Questions
  • Advanced Informatica Cloud Interview Questions
  • Informatica Cloud Scenario-Based Interview Questions

Let's explore basic interview questions and then gradually move to the advanced level.

Basic Informatica Cloud Interview Questions:

1) What is data integration?

Data integration is one of the essential tasks involved in data engineering. It is a process to connect diversified data sources, combine data, and provide a unified view for users. 

2) What are the everyday tasks involved in data integration?

Data integration consists of the following three steps:

  • Cleansing, 
  • ETL mapping, 
  • Transformation

3) Can you explain how the data integration process works?

The data integration process starts with the client's request. When a client requests a master server for data, it sources requested data from internal and external sources. After extraction, the master server consolidates data into a single set and sends it to the client. 

4) What is Informatica Intelligent Cloud Services (IICS)?

Informatica Intelligent Cloud (IICS) is a next-generation iPaaS data integration solution offered by Informatica. It offers advanced features to integrate business data, application integration, API management, etc.

5) What are the core components of the Informatica cloud?

Following are the core components of Informatica cloud:

  • Runtime environments
  • Informatica Cloud Secure Agent
  • Informatica Cloud organization
  • Connections

6) Explain the Informatica cloud Runtime Environment.

It is a runtime environment that facilitates interfaces to run IICS tasks & task flows. Using this runtime environment, users can access and execute tasks. Each runtime environment consists of at least one secure agent that runs tasks and facilitates secure communication between the organization & Informatica cloud services.

7) What are the different ways available to set up runtime environments?

It is possible to set the runtime environment in the following ways:

Cloud Hosted Agent.
Secure Agent

8) Define Informatica Cloud Secure Agent.

Cloud secure agent is a program that helps to run tasks and facilitates secure communication between organizations & Informatica cloud services. When a user executes a task, the Secure Agent securely accesses Informatica cloud hosting to retrieve task information. It acts as a link between sources and targets to transfer data.

9) Explain the Informatica Cloud organization

An Informatica organization is a component in the IICS repository that stores all user accounts, licenses, tasks, mappings, jobs, security, and more. A user can access one or more organizations, and based on the license type, one can create organizations and sub-organizations.

10) Define Connections in Informatica Cloud.

Using connections in the Informatica cloud, we can connect to data in the cloud, on-premises, databases, platforms, flat files, etc.

Advanced IICS Informatica Interview Questions:

11) Name a Few Connection Types supported by Informatica Cloud.

Following are the connection types available to work with data:

  • Relational database connection
  • HDFS connection
  • File transfer connections
  • Teradata connection

12) What is the Synchronization task?

The synchronization task automates the data synchronization process between the source and the target. Data Synchronization helps maintain the same data between different systems and enables accuracy.

13) Name the types of assets that you can create in an Informatica cloud.

Following are the types of assets that you can create are:

  • Process Object
  • Service Connectors
  • App Connection
  • Process
  • Guides

14) Explain discovery IQ.

Discovery IQ gives you a complete overview of the number of processes and jobs in your organization. Using Discovery IQ, you can even get to know more about KPIs such as data volumes, successful & failed jobs, etc. You can also perform log analysis by directly downloading from Discovery IQ.

15) Why do we use data replication tasks?

Data replication tasks enable users to replicate data from databases or selected sources to a desired destination. The replication task has a built-in incremental processing mechanism, which you can use to replicate rows and columns that have changed since the last runtime.

16) Define Mapping?

Mapping is an advanced mechanism used for complex logic implementations not executable by data replication and synchronization methods.  Mapping allows you to perform various tasks, such as joining different source systems, defining data flow logic, preparing data for offline reports, and implementing the warehouse system.

Informatica Cloud (IICS) Scenario Based Interview Questions:

17) What is data Assessment?

The Data Assessment task in IICS streamlines the process of assessing data quality. It also lets you check file completeness, record duplication, field conformances, address validity, and more. You can configure filters on data to get the data that meets requirements.

18) What is data masking?

The data masking mechanism enables you to stop exposing sensitive data to non-production environments. Using data masking rules, you can define the logic to mask or replace selected columns with duplicate values. 

19)What are the mapping components?

Mapping components are:

  • Source tables
  • Variables & Parameters
  • Target objects
  • Mapping Transformations

20) Name a few operations performed using IICS Rest API.

Using REST APIs, we can access data from the Informatica cloud. You can also perform the below tasks:

  • Create and update connections
  • Start & Monitor Jobs,
  • Delete Jobs


Informatica Cloud has gained massive popularity with its modern features and supporting data engineering processes with continuous innovativeness. Very soon, we will add this blog with more Informatica IICS interview questions and answers.
