Understanding the Basics

Before we dive into the intricacies of Informatica Cloud, let’s lay the foundation by addressing some fundamental questions:

1. What is data integration?
   Data integration is the process of combining data from various sources into a unified and consistent view, enabling organizations to gain valuable insights and make informed decisions.

2. What are the everyday tasks involved in data integration?
   The three primary tasks involved in data integration are:

   • Cleansing: Ensuring data quality by identifying and resolving issues such as duplicates, inconsistencies, and missing values.
   • ETL (Extract, Transform, Load) mapping: Extracting data from sources, transforming it according to business rules, and loading it into target systems.
   • Transformation: Applying complex logic and calculations to reshape and enrich data to meet specific requirements.

3. Can you explain how the data integration process works?
   The data integration process typically involves the following steps:

   • A client requests data from a master server.
   • The master server sources the requested data from internal and external sources.
   • The data is extracted, consolidated into a single set, and sent to the client.

4. What is Informatica Intelligent Cloud Services (IICS)?
   Informatica Intelligent Cloud Services (IICS) is a next-generation iPaaS (Integration Platform as a Service) data integration solution offered by Informatica. It provides advanced features for integrating business data, application integration, API management, and more.

5. What are the core components of the Informatica Cloud?
   The core components of the Informatica Cloud are:

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

Diving Deeper: Advanced Informatica Cloud Concepts

As you progress in your Informatica Cloud journey, you’ll encounter more intricate concepts and terminologies. Here are some advanced Informatica Cloud interview questions to prepare for:

1. Explain the Informatica Cloud Runtime Environment.
   The Informatica Cloud Runtime Environment is an execution platform that facilitates running IICS tasks and task flows. It consists of at least one Secure Agent that runs tasks and enables secure communication between the organization and Informatica Cloud Services.

2. What are the different ways to set up Runtime Environments?
   Runtime Environments can be set up in the following ways:

   • Cloud Hosted Agent
   • Secure Agent

3. Define Informatica Cloud Secure Agent.
   The Informatica Cloud Secure Agent is a lightweight program installed on a server within an organization’s network. It helps run tasks and facilitates secure communication between the organization and Informatica Cloud Services. When a task is executed, the Secure Agent securely accesses Informatica Cloud hosting to retrieve task information and acts as a link between sources and targets for data transfer.

4. Explain the Informatica Cloud organization.
   An Informatica Cloud organization is a component in the IICS repository that stores user accounts, licenses, tasks, mappings, jobs, security settings, and more. Users can access one or more organizations, and based on their license type, they can create organizations and sub-organizations.

5. Define Connections in Informatica Cloud.
   Connections in the Informatica Cloud enable users to connect to data sources in the cloud, on-premises databases, platforms, flat files, and other data storage systems.

6. Name a few Connection Types supported by Informatica Cloud.
   Informatica Cloud supports the following connection types:

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

7. What is a Synchronization task?
   A Synchronization task automates the data synchronization process between a source and a target. It helps maintain consistent data across different systems, enabling accuracy and ensuring data integrity.

8. Name the types of assets that you can create in the Informatica Cloud.
   The types of assets that can be created in the Informatica Cloud include:

   • Process Objects
   • Service Connectors
   • App Connections
   • Processes
   • Guides

9. Explain Discovery IQ.
   Discovery IQ provides a comprehensive overview of the processes and jobs in an Informatica Cloud organization. It allows users to monitor Key Performance Indicators (KPIs) such as data volumes, successful and failed jobs, and perform log analysis by directly downloading logs from Discovery IQ.

10. Why do we use Data Replication tasks?
    Data Replication tasks enable users to replicate data from databases or selected sources to a desired target destination. These tasks have a built-in incremental processing mechanism, which allows users to replicate only the rows and columns that have changed since the last runtime.

11. Define Mapping.
    Mapping is an advanced mechanism used for implementing complex logic that cannot be executed by Data Replication and Synchronization tasks. Mapping allows users to perform various tasks, such as joining data from different source systems, defining data flow logic, preparing data for offline reports, and implementing data warehouse systems.

Real-World Scenarios: Putting Your Knowledge to the Test

To truly assess your Informatica Cloud expertise, interviewers often present real-world scenarios and case studies. These types of questions test your ability to apply your knowledge in practical situations and demonstrate problem-solving skills. Here are a few examples:

1. What is Data Assessment?
   The Data Assessment task in IICS streamlines the process of assessing data quality. It allows users to check file completeness, record duplication, field conformance, address validity, and more. Users can configure filters to retrieve data that meets specific requirements.

2. What is Data Masking?
   Data Masking is a mechanism that prevents sensitive data from being exposed in non-production environments. By defining data masking rules, users can specify the logic to mask or replace selected columns with dummy values, ensuring data privacy and compliance.

3. What are the components of a Mapping?
   The components of a Mapping include:

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

4. Name a few operations that can be performed using the IICS REST API.
   Using the IICS REST API, users can access data from the Informatica Cloud and perform the following tasks:

   • Create and update connections
   • Start and monitor jobs
   • Delete jobs

Throughout the interview process, be prepared to discuss real-world examples and scenarios that demonstrate your practical experience and problem-solving abilities.
