Which statement best describes serverless computing?

The developer must manage the operating system and runtime patches.

The application runs on a fixed set of servers that are always on.

The developer must provision and manage virtual machines to run code.

The cloud provider manages the infrastructure, and the developer writes and deploys functions that run on demand.

What is the main purpose of a layered (n-tier) architecture?

To allow each layer to directly access the database without restrictions.

To separate concerns by dividing the application into distinct layers with specific responsibilities.

To eliminate the need for any communication between components.

To ensure that all components are deployed as a single unit.

Which practice is a core component of DevOps?

A single, monolithic release at the end of the project

Separate environments for development and operations with no shared tools

Manual code reviews and handoffs between teams

Continuous integration (CI) and continuous delivery (CD)

A company is migrating from a monolithic application to microservices. They have a critical business process that requires a transaction to either fully complete or fully roll back across multiple services. The team is considering an event-driven approach with a message broker. Which strategy best handles this distributed transaction requirement?

Use a two-phase commit protocol across all services.

Use synchronous REST calls with a global lock to ensure consistency.

Use a shared database so that all services can participate in a single ACID transaction.

Use the saga pattern, where each service performs its local transaction and publishes events to trigger the next step, with compensating actions for rollback.

How does automation in a CI/CD pipeline support rapid and reliable software delivery?

By automatically building, testing, and deploying code changes with minimal manual intervention.

By eliminating the need for version control.

By requiring manual approval at every stage to ensure quality.

By deploying all changes directly to production without testing.
