Question 1

An organization intends to move a web application that is accessible by outside users to Azure. A cloud deployment option has been requested from Peter in order to reduce the amount of administrative work required to manage the web application.
Which of the following should Peter incorporate into the answer to satisfy the condition?

Accepted Answer

Platform as a Service (PaaS)

Answer

To significantly reduce the amount of administrative work required to manage a web application, Platform as a Service (PaaS) is the ideal cloud deployment option. PaaS provides a complete development and deployment environment in the cloud, abstracting away the need to manage underlying infrastructure like operating systems, servers, and networking. This allows developers to focus solely on their application code.

Question 2

Which of the following options for cloud deployment is recommended for Azure virtual machines?

Accepted Answer

Infrastructure as a Service (IaaS)

Answer

Azure Virtual Machines are a prime example of Infrastructure as a Service (IaaS). With IaaS, the cloud provider manages the underlying physical infrastructure, while the user is responsible for the operating system, applications, data, and runtime. This model provides maximum flexibility and control over the computing environment, making it suitable for migrating existing on-premises servers.

Question 3

100 servers are part of your on-premises network. You must advocate for a solution that gives your users more resources. Costs associated with capital and operating expenditures must be kept to a minimum.
What should the recommendation contain?

Accepted Answer

A hybrid cloud

Answer

A hybrid cloud solution is ideal for extending resources while minimizing capital and operating expenditures. It allows the company to leverage its existing 100 on-premises servers while seamlessly integrating with the public cloud for additional, scalable resources. This approach avoids large upfront capital investments in new hardware and utilizes the public cloud's pay-as-you-go operational expense model for flexibility and cost efficiency.

Question 4

A company intends to move a number of servers from an on-premises network to Azure. 
Which of the following is an advantage of an on-premises network over employing a public cloud 
service for the servers?

Accepted Answer

Public cloud is a shared entity whereby multiple corporations each use a portion of the resources in the cloud

Answer

The statement 'Public cloud is a shared entity whereby multiple corporations each use a portion of the resources in the cloud' accurately describes the multi-tenant nature of a public cloud. An advantage of an on-premises network over this shared model is that all resources are dedicated solely to the owning organization. This provides complete control, enhanced security isolation, and potentially more predictable performance, as resources are not contended with other tenants.

Question 5

On the Hyper-V hosts in a data center, a company has 1,000 virtual machines (VMs) hosted on them. All of the virtual machines will be switched over to a pay-as-you-go Azure subscription. John has been asked to provide a cost-benefit analysis for the proposed Azure solution.
Which of the available expense models ought he to pick in this circumstance?

Accepted Answer

Operational

Answer

Migrating to a pay-as-you-go Azure subscription means the company will pay for cloud resources as they consume them, without significant upfront investments in hardware. This aligns with an operational expenditure (OpEx) model, where costs are treated as ongoing expenses rather than capital investments. John should therefore pick the operational expense model for his cost-benefit analysis.
