AZ-900 Azure Fundamentals- Quiz 1

Q1.
Your company migrates virtual machines (VMs) from an on-premises data center to Azure. As a part of the migration, all existing physical servers in your data center are decommissioned. The migrated workload runs on Azure VMs.

What are the two possible benefits of this cloud migration? (CHOOSE 2)

Ownership of physical infrastructure

Reduced Service Level Agreement (SLA)

Pay-per-use model

Absence of upfront costs

WHY A IS False?	CONCEPT: Ownership of physical infrastructure	As a cloud customer, you only lease (rent) cloud computing resources. Ownership of underlying physical hardware belongs to the actual cloud service provider.
WHY B IS False?	CONCEPT: Reduced Service Level Agreement (SLA)	As a part of this cloud migration, you are also very likely to get not a lower, but a higher SLA. Most Azure services and resources offer SLA of 99.9% and above, which is much higher uptime than one can achieve at an on-premises data center.
WHY C IS True?	CONCEPT: Pay-per-use model	As a client, you pay for the actual consumption of the selected cloud services and resources using a pay-per-use charging model.
WHY D IS True?	CONCEPT: absence of upfront costs	With cloud infrastructure, there are no upfront costs for cloud customers because the cost of hardware provisioning and ownership is taken care of by the cloud provider.
Short Trick	It's a definition question. For this, you must know the benefits of moving to the cloud. Learn more about this on AZ-900 CHEAT SHEET 2022 (kaustubhsharma.com)

Q2.
Why would someone prefer a Consumption-based pricing model as opposed to a Time-based pricing model?

Pricing model is simpler & easier to understand.

It is always cheaper to pay for consumption than to pay by the hour.

You can easily predict cost of service into future.

You can save a lot of money if you don't use the resource often as opposed to having it available for use 24/7.

WHY A IS False?	CONCEPT: Simplicity	Time based model could be more simple & easier to understand as their is fixed price we need to pay.
WHY B IS False?	CONCEPT: Cheaper	That's not true. The time-based model can be cheaper in some cases. especially If we are using our resources using 24/7.
WHY C IS False?	CONCEPT: Prediction of the cost of service	You can predict the cost of service as in the consumption model, pricing is based on consumption, which varies based on various variable factors like user requests, etc. which we can't predict accurately. However, in the time-based model, we pay for the time for which we are have reserved the resources even if we are not using the resources., so we can easily predict the cost based on the time for which we want to use the resources.
WHY D IS True?	CONCEPT: Saves Money if not using 24/7	In consumption based model, if we only pay for what we are actually paying, which saves us a lot of money if we don't use resources often. In Time-base model, we pay for the time for which we are have reserved the resources even if you are not using the resources.
Short Trick	Cloud service providers operate on a consumption-based(pay-as-you-go) model, which means customers have to "only pay for the resources that they are using".

Q3.
You plan to migrate a web application to Azure. The web application is accessed by external users.
You need to recommend a cloud deployment solution to minimize the amount of administrative effort used to manage the web application.
What should you include in the recommendation?

Software as a Service (SaaS)

Platform as a Service (PaaS)

Infrastructure as a Service (IaaS)

Database as a Service (DaaS)

WHY A IS False?	CONCEPT: Software as a Service (SaaS)	In SaaS, service provider is responsible for managing components. However, in this question, we already have an existing application which awe have to migrate to Azure. We just don't want to manage the admin part of web application, but we still want to manage the application code & other stuff related to application. So, Saas is not a good choice here in this case.

WHY B IS True?	CONCEPT: Platform as a Service (PaaS)	PaaS makes for a flexible development platform where the customer can focus on development rather than being concerned with managing the underlying platform. That's a perfect fit for our requirements. Read more about IaaS, Paas & SaaS at What is IAAS, PAAS & SAAS ?
WHY C IS False?	CONCEPT: Infrastructure as a Service (IaaS)	In IaaS, a cloud service provider will provide you the infrastructure to host the web application. Rest all you have to manage like Runtime Middleware OS, etc, Which we want to reduce as per the question. So, Iaas is not the right fit in our case. Read more about IaaS, Paas & SaaS at What is IAAS, PAAS & SAAS ?
WHY D IS False?	CONCEPT: Database as a Service (DaaS)	Database as a Service is a part of Infrastructure as a Service. So similar reason. Read more about IaaS, Paas & SaaS at What is IAAS, PAAS & SAAS ?
Short Trick	" minimize the amount of administrative effort" will leave you with the option of SaaS & PaaS, as this is an existing application & we just want to minimize the administration part, so PaaS will be the best fit for us. PaaS makes for a flexible development platform where the customer can focus on development rather than being concerned with managing the underlying platform. That's a perfect fit for our requirements. Read more about IaaS, Paas & SaaS at What is IAAS, PAAS & SAAS ?
