The president of your company has tasked you with implementing cloud services as the most efficient way of obtaining a robust disaster recovery configuration for your production services.
Which of the cloud deployment models would you MOST likely be exploring?
A hybrid cloud model spans two or more different hosting configurations or cloud providers. This would enable an organization to continue using its current hosting configuration, while adding additional cloud services to enable disaster recovery capabilities. A hybrid model offers the flexibility to integrate on-premises infrastructure with cloud resources, which is ideal for creating a robust disaster recovery solution. This model ensures that critical workloads can be maintained in the event of a disaster by leveraging both private and public cloud environments. Other models like public, private, and community clouds do not provide the same level of flexibility and integration needed for an effective disaster recovery strategy.
Is the company currently operating on prem or in cloud? If it's currently in cloud, which model? The answer incorrectly assumes that we know the information.
I will go public is most efficent way IMO
The question doesn't mention the production environment is a private cloud environment. According to NIST's definition, it cannot be a Hybrid Cloud if it does not involves two of more distinct cloud infrastructures (private, community, or public).
I don't think the question need to specify that the production environment need to be private cloud for the answer to be hybrid. It's hybrid because sensitive and PII data are usually backed up on private cloud, while other data can be backed up on public cloud. So, private+public=hybrid in this case.
In this specific case, nothing says that production would move from onprem to cloud so we should assume only bcp/dr elements may be put to cloud meaning either simply backup and archiving and perhaps also the replication of on-prem resources to their cloud counterparts whenever it is needed. In any case, this is a hybrid setup which may require some degree of interoperability. Public cloud would be more suitable if they specify least cost and least effort without specific security needs, but it's not mentioned.

Public(AWS or Azure) makes more sense to me. Hybrid if needing more shared security responsibility.
pg 25 of the study guide "“Cloud bursting” and disaster recovery can be enhanced by hybrid cloud deployments; “cloud bursting” allows for public cloud resources to be utilized when a private cloud workload has reached maximum capacity." Also, if you are "implementing" cloud services I am going to say Hybrid as you can't just go from on-prem to cloud unless you're only doing IaaS / VMs.
A: is the correct answer. No other one would even closely come to benefit DR as well as hybrid would.
I think its public, question doesnt talk about PII or SPI/PHI, it doesn't say you have a mix of clouds. robust DR is only three in public.
A: Hybrid
Disaster takes place, it would make sense that the area the region that is impact would impact your On-prem. Public cloud would allow you to set-up your DR location in a totally different region giving you the best option. Not to mention Cost savings.
Another tricky question, where you could argue for both A & D, but in my opinion, the way it is written, I would go for A
A is the correct answer, it is Hybrid DR model
The question implies that you DO NOT have a clod solution. DR context implies that your current location is no longer usable for ops so the DR location must be in a different location than your current location, Cloud would allow you to recover faster and with less cost. Hybrid is best cloud solution for this.
A. Hybrid
Public cloud services are often the go-to choice for robust disaster recovery (DR) configurations. They offer: Scalability & Flexibility: Resources can be provisioned on-demand to match your DR needs. Cost Efficiency: You typically pay only for what you use, avoiding significant upfront capital expenditure. Geographical Redundancy: Public cloud providers have data centers in multiple locations, enhancing resiliency and failover capabilities. In contrast, hybrid, private, or community models either involve more complex management or don't inherently offer the broad, on-demand resource availability that public clouds do for DR purposes.
