Exam CCSP topic 1 question 364 discussion

The question is talking about BCDR, if you are unable to move your services/apps to another cloud provider, how can you achieve BCDR !! So the answer is Portability.

Elasticity is the most important cloud concept for Business Continuity and Disaster Recovery (BCDR) because it allows cloud resources to scale up or down automatically in response to demand. This ensures that an organization can quickly recover from disruptions by provisioning additional resources as needed without manual intervention. Why Not the Others? A. Reversibility → Refers to the ability to remove data and applications from a cloud provider, which is important but not critical for immediate BCDR needs. C. Interoperability → Ensures that cloud systems work with other platforms, but does not directly address disaster recovery. D. Portability → Focuses on moving workloads between cloud providers, but BCDR is more about quick recovery and scaling than migration.

In that case it should be reversibility s you have to move data back to on prem once you service resumes. The answer should be elasticity.

B: Elasticity

B. Elasticity. Elasticity is a key concept in cloud computing that refers to the ability of a cloud service to scale up or down in response to changes in demand. This is particularly important for organizations that are considering using cloud services for business continuity and disaster recovery (BCDR) planning and solutions, as it allows them to quickly and easily increase or decrease their use of cloud resources as needed to support their business operations. Elasticity is typically achieved through the use of automation and other technologies that enable cloud services to automatically scale up or down in response to changes in demand. This can help organizations to ensure that they have the right amount of resources available to support their BCDR needs at all times, and can help to reduce costs by avoiding the need to provision more resources than are actually needed.

For people saying Reversilibilty -- you know it wouldn't hurt to read the explanation once in a while, I insist please do read the explanation!

The question did not state what is current company's setup like. They probably already in the cloud and looking for another cloud for DR. So, the question is not clear.

Reversibility sounds good but it is in context when you move out of cloud completely to your dc. In this case, we are not doing this. This leaves Portability as the most viable option. We failover from DC to Cloud and go back to DC.

Disagree with Portability. The question seems to ask if you are using the cloud as the BCDR. not what you would do if your cloud goes down and needs to move to another cloud. That's where portability would play in.

"Reversibility is the ability of a cloud customer to take all their systems and data out of a cloud provider and have assurances from the cloud provider that all the data has been securely and completely removed within an agreed-upon timeline. In most cases this will be done by the cloud customer by first retrieving all their data and processes from the cloud provider, serving notice that all active and available files and systems should be deleted, and then removing all traces from long-term archives or storage at an agreed-upon point in time. Reversibility also encompasses the ability to smoothly transition to a different cloud provider with minimal operational impact." So I still don't know what the answer is.

A. should be the answer. You need the data back, so you got to make sure that reversibility is working otherwise you are gonna lose data regardless of portability
