Question 1

What is the purpose of Informatica Cloud's 'Cloud Mass Ingestion' service?

Accepted Answer

To bulk-ingest large volumes of data from databases, files, or streaming sources into cloud storage or data warehouses

Answer

Cloud Mass Ingestion automates the high-volume, high-speed movement of data from on-premises or cloud sources into cloud targets such as data lakes and data warehouses.

Question 2

Which cloud storage class is most cost-effective for data that is accessed less than once per year?

Accepted Answer

Archive/Glacier storage

Answer

Archive-tier storage (e.g., AWS Glacier, Azure Archive) has the lowest storage cost but highest retrieval latency and cost, making it ideal for rarely accessed data.

Question 3

In IICS, what does the 'pushdown optimization' feature do?

Accepted Answer

Pushes mapping logic execution down to the source or target database engine

Answer

Pushdown optimization translates mapping logic into native SQL and executes it on the source or target database, reducing data movement and improving performance.

Question 4

Which NIST cloud characteristic allows users to provision computing resources unilaterally without requiring human interaction with the service provider?

Accepted Answer

On-demand self-service

Answer

On-demand self-service means consumers can automatically provision capabilities such as server time and storage as needed without service-provider interaction.

Question 5

What is the role of an API gateway in a cloud microservices architecture?

Accepted Answer

Acts as a single entry point that routes, authenticates, and rate-limits client requests to backend services

Answer

An API gateway sits in front of microservices to handle cross-cutting concerns like authentication, SSL termination, rate limiting, and request routing.
