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​

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.

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​

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 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​

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.

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​

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.

Given the benefits of microservices, which scenario would most likely benefit from adopting a microservices architecture?
A legacy application with tightly coupled components that rarely change
A monolithic application that performs a single, unchanging function
A new cloud-based application requiring frequent updates and scalability
A small desktop application used by a single user

Explanation​

A new cloud-based application requiring frequent updates and scalability would most likely benefit from adopting a microservices architecture.

What is a key characteristic of a Virtual Private Cloud (VPC)?
It is hosted in a private data center.
It is limited by the available hardware and less scalable.
It shares resources with other companies.
It involves logical isolation within a public cloud provider's infrastructure.

Explanation​

A key characteristic of a Virtual Private Cloud (VPC) is that it involves logical isolation within a public cloud provider's infrastructure.

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​

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.
