Your company, Tech Innovators Inc., is planning to migrate its IT infrastructure to the cloud. The company requires a solution that offers high scalability and does not want to invest in managing physical hardware. However, the company also needs to ensure that its cloud resources are isolated from other companies for security reasons.
Which cloud deployment model should Tech Innovators Inc. choose?
Community Cloud
Incorrect answer:
Private Cloud
On-Premises Data Center
Virtual Private Cloud (VPC)

Explanation​

Click to expand...
Tech Innovators Inc. should choose a Virtual Private Cloud (VPC). This model provides high scalability, does not require management of physical hardware, and ensures that resources are logically isolated for security.

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.

Explanation​

Click to expand...
To ensure Microservice-A can reliably find Microservice-B, you should use a service registry where Microservice-B registers itself and Microservice-A queries it.

This approach allows Microservice-A to dynamically discover the current instances of Microservice-B, even as they are created and destroyed based on workload demands. Hard-coding IP addresses is not reliable in dynamic environments, and simply increasing instances does not address the discovery challenge.

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.

Explanation​

Click to expand...
The fan-out/fan-in pattern is more efficient because it allows multiple functions to run in parallel and then aggregate the results, speeding up data processing. In contrast, a function chain processes tasks sequentially, which is less efficient for parallel workloads.

A sysadmin needs to deploy a cloud application that does not rely on a single vendor. The sysadmin requires greater flexibility and disaster mitigation.
Which cloud option best fits this need?
Hybrid
On-Premises
Multi-cloud
Private

Explanation​

Click to expand...
The best cloud option for this need is multi-cloud.
Multi-cloud allows a sysadmin to deploy applications across multiple cloud providers, avoiding reliance on a single vendor. This provides greater flexibility, as it enables the use of different services from different providers. It also enhances disaster mitigation, since if one cloud provider experiences an outage, the services running on other providers can continue to operate.

Which of the following is a use case for hybrid cloud solutions?
Hosting all services in a public cloud environment
Avoiding cloud services entirely
Disaster recovery
Using only on-premises data storage

Explanation​

Click to expand...
The use case for hybrid cloud solutions is disaster recovery.

Hybrid cloud solutions combine both on-premises infrastructure and public or private cloud resources, making them ideal for disaster recovery scenarios. They allow organizations to back up critical data and applications in the cloud, ensuring continuity if the primary infrastructure fails, while still utilizing on-premises systems for day-to-day operations.

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.

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 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.
