If you are about to give your data engineering interview and IICS is one of the skills that you included in your resume then this blog is for you! Informatica Cloud is a leading cloud integration and data management platform. This IICS interview questions and answers blog acts as a simple guide and helps you with the required knowledge to clear your next interview.
All these 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:
Let's explore basic interview questions first and then gradually move to the advanced level.
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.
Data integration consists of the following three steps:
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 data set and sends it to the client.
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.
Following are the core components of Informatica cloud:

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.
It is possible to a setup the runtime environment in the following ways:
Cloud Hosted Agent.
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.
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 have access to one or more organizations and based on the license type one can create organizations and sub-organizations.
Using connections in the Informatica cloud we can connect to data in the cloud, on-premises, databases, platforms, flat files, etc.
Following are the connection types available to work with data:
The synchronization task automates the data synchronization process between the source and the target. Data Synchronization helps in maintaining the same data between different systems and enables accuracy.
Following are the types of assets that you can create are:
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.
Data replication task enables the users to replicate data from databases or selected sources to a desired destination. The replication task comes with a built-in incremental processing mechanism using which you can choose to replicate rows and columns that have changed since the last runtime.
Mapping is an advanced mechanism used for complex logic implementations that are not executable by data replication and data synchronization methods. Mapping allows you to perform various tasks such as joining different source systems, defining data flow logic, data preparation for offline reports, and implementing the warehouse system.
The Data Assessment task in IICS streamlines the process to assess data quality. It also enables you to check things like file completeness, record duplication, field conformances, address validity, and more. You can configure filters on data to get the data that meets requirements.
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.
Mapping components are:
Using REST APIs we can access data from the Informatica cloud. You can also perform the below tasks:
Summary:
Informatica cloud has got huge popularity with its modern features and supporting data engineering process with continuous innovativeness. Very soon we are going to add this blog with more IICS interview questions and answers.
