Microsoft AZ-900 Exam - Topic 13 Question 15 Discussion

Actual exam question for Microsoft's AZ-900 exam

Question #: 15
Topic #: 13

Your company plans to deploy several custom applications to Azure. The applications will provide invoicing services to the customers of the company. Each application will have several prerequisite applications and services installed.

You need to recommend a cloud deployment solution for all the applications.

What should you recommend?

ASoftware as a Service (SaaS)

BPlatform as a Service (PaaS)

CInfrastructure as a Service (laaS)

Show Suggested Answer

Suggested Answer: C

Infrastructure as a service (IaaS) is an instant computing infrastructure, provisioned and managed over the internet. The IaaS service provider manages the infrastructure, while you purchase, install, configure, and manage your own software

Incorrect Answers:

A: Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring, and office tools. In this scenario, you need to run your own apps, and therefore require an infrastructure.

Platform as a service (PaaS) is a complete development and deployment environment in the cloud. PaaS includes infrastructure---servers, storage, and networking---but also middleware, development tools, business intelligence (BI) services, database management systems, and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing, and updating.

I’m not sure if IaaS is the best choice here.

Wait, can I really run all those prerequisites on PaaS?

I lean towards PaaS as well, but I wonder if there are scenarios where IaaS would be more beneficial for our invoicing services.

I practiced a similar question, and I feel like IaaS could be too low-level for deploying custom applications with all those prerequisites.

I'm not entirely sure, but I remember that SaaS is more about delivering software over the internet, which might not fit our needs here.

I think PaaS might be the best option since it allows for easier management of applications and their dependencies.

Hmm, I'm a bit unsure about this one. I'll have to think it through step-by-step to make sure I get the right answer.

Hmm, I'm a little unsure about this one. I know variable costs change with production, but I'm not totally confident in my understanding of the differences between the options.

This looks like a straightforward question about setting up log exports to a SIEM. I think the key is to create a log sink at the organization level to capture all the relevant logs across projects.

Applying policies to sites and VPNs feels more like a final step; I think we really start with configuring the groups.
