Which design pattern would be more efficient for processing large amounts of data in parallel, and why?
Fan-out/fan-in, because it allows multiple functions to run simultaneously and aggregate results.
Fan-out/fan-in, because it allows multiple functions to run simultaneously and aggregate results.
Fan-out/fan-in, because it maintains data and state across functions.
Function chain, because it ensures each function completes before the next one starts.

You are designing a microservices-based application where Microservice-A needs to communicate with Microservice-B. Both microservices are dynamically created and destroyed based on workload demands.
Which approach should you take to ensure Microservice-A can reliably find Microservice-B?
Increase the number of instances of Microservice-B to ensure availability.
Increase the number of instances of Microservice-B to ensure availability.
Use a service registry where Microservice-B registers itself and Microservice-A queries it.
Hard-code the IP address of Microservice-B in Microservice-A.

What is the primary characteristic of serverless architectures?
They eliminate the need for servers entirely.
They abstract hardware, operating system, and service maintenance away from developers.
They are only used for large-scale monolithic programs.
They require developers to manage server functionality.

Explanation​

Click to expand...
The primary characteristic of serverless architectures is that they abstract hardware, operating system, and service maintenance away from developers. This allows developers to focus on writing code, while the cloud provider handles the infrastructure management, scaling, and server provisioning automatically. Developers don’t need to worry about server management, capacity planning, or maintenance tasks, which are handled by the cloud provider.

What term is used to describe how microservices find each other in a dynamic environment?
Service chaining
Service coupling
Service discovery
Service registry

Explanation​

Click to expand...
The term used to describe how microservices find each other in a dynamic environment is service discovery.
Service discovery helps microservices dynamically locate and communicate with each other in environments where services may start, stop, or change frequently. It often involves a service registry, which is a database of available services and their network locations.

What is a function in the context of serverless architectures?
A complex application handling multiple purposes
A static piece of code that is always running
A single programmatic capability triggered by an event
A long-running process that maintains data and state

Explanation​

Click to expand...
In the context of serverless architectures, a function is a single programmatic capability triggered by an event.

It is a small, independent piece of code that runs in response to specific events, such as HTTP requests, file uploads, or database changes. Once the event is processed, the function terminates, and it does not persist or maintain state between invocations. This is the core idea behind Function-as-a-Service (FaaS) within serverless architectures.
