Suggested Answer:
Box 1: No -
It is not true that a company must always migrate from a private cloud model to implement a hybrid cloud. You could start with a public cloud and then combine that with an on-premise infrastructure to implement a hybrid cloud.

Box 2: Yes -
A company can extend the capacity of its internal network by using the public cloud. This is very common. When you need more capacity, rather than pay out for new on-premises infrastructure, you can configure a cloud environment and connect your on-premises network to the cloud environment by using a VPN.

Box 3: No -
It is not true that only guest users can access cloud resources. You can give anyone with an account in Azure Active Directory access to the cloud resources.
There are many authentication scenarios but a common one is to replicate your on-premises Active Directory accounts to Azure Active Directory and provide access to the Azure Active Directory accounts. Another commonly used authentication method is 'Federation' where authentication for access to cloud resources is passed to another authentication provider such as an on-premises Active Directory. https://azure.microsoft.com/en-gb/overview/what-is-hybrid-cloud-computing/

Should be No, No, No. Hybrid cloud will extend internal network.

what if they are dealing non-sensitive data? Maybe data that they WANT to post online? Maybe it's an open source project of some kind. Like Firefox browser organization it's open source. Something along these lines.

It would be strange, but you could do the other way around - start with a fully public cloud and extend it back to a new private cloud on premises. A possible example is adoption of legacy tech or a solution with very specific security requirements that aren't supported in public cloud.

I don't get the first question. If you don't migrate from private cloud, how will you achieve hybrid cloud, you better then stay using private cloud.

Extending private cloud to public cloud = Hybrid cloud The second of this question is referring to only left side of the above equation hence yes is correct answer.

"A company can extend the capacity of its internal network by using the public cloud" This is yes. Example: A small company with a dozen PCs all on a Workgroup, no domain, and no on-site servers, all share data via Sharepoint and OneDrive.

I think the key point here is “Migrate” because a hybrid is a combination of private and public resources so migrating is moving from one to another… just saying.. please correct me if you have a different opinion

So I don’t think it’s correct except it’s indicated that “migrating some of its resources”

Second could be NO. Imagine that you have an internal network class C (/24) if the network is almost full even if you go to the public cloud the capacity of the network capacity cannot be expanded. The question is related to the network capacity not to the capacity to grow in compute resources

This is playing with words, but I disagree for the first statement: you must always migrate from private to public cloud to reach the hybrid model ... but obviously not all of the resources

An organization could start with a public cloud, and after that create an on-premises datacenter (private cloud). That would also result in a hybrid cloud.

Do you agree or disagree because you stated you agree but your reasoning suggest you agree. Private > Hybrid isn't the only way. You can also go public > hybrid. A reason for this could be to meet compliance during expansions of services offered across countries or services.

No No No. I disagree. It is not stating it will extend the internal network. It is stating it can extend the CAPACITY of the network. Meaning you can offload resources into the public cloud easier than in your internal network.. i.e Even with VPN, this doesn't qualify as an internal network extension but an extension of the total network.

Weird that the second question would be no. How does VPNing to the public cloud extend the capacity of your internal network? By comparison if I installed an on prem server, I wouldn't say that my network capacity has increased. So connecting to one in the cloud wouldn't either, would it.

What is an internal network? Ask yourself. An internal network means it's like a Private network. When you reach the public cloud, it's not an internal network.
