Exam CAS-004 topic 1 question 154 discussion

Alternative provider BCDR: This involves using a different cloud provider for DR. This can provide a higher level of resilience because an outage in one provider might not affect the other.

Another Source. B. Cloud provider BCDR: This option leverages the cloud provider's built-in disaster recovery and business continuity capabilities. Cloud providers typically offer redundancy, failover services, and rapid scalability, making recovery seamless and efficient. The cloud provider's infrastructure is designed specifically to handle cloud-based services, ensuring compatibility and performance. This approach minimizes downtime and is the most aligned with a cloud environment's operational model. While alternative provider may refer to a completely different third-party provider used as a backup, this may provide additional fault tolerance, it introduces complexity due to differences in infrastructure, protocols, and technologies between the primary and alternative cloud providers. Using alternative providers for disaster recovery often involves higher costs and time delays when switching between environments.

The most appropriate choice for this situation is: B. Cloud provider BCDR (Business Continuity and Disaster Recovery). REASONS: Cloud provider BCDR typically includes features like automatic backups, geographic redundancy, failover, and recovery solutions that are specifically designed to handle cloud-based resources. Cloud providers have the infrastructure and capabilities to ensure high availability, replication, and disaster recovery in case of a failure. It allows for seamless integration and faster recovery times compared to other solutions, especially in cases where the environment is entirely cloud-based. While C. Alternative provider BCDR: Using an alternative provider for disaster recovery introduces additional complexity and costs, and it may not be as tightly integrated with your cloud environment as the cloud provider’s native solution.

C is the best option for disaster recovery

While Cloud provider BCDR (Option B) leverages the built-in disaster recovery features of the primary cloud provider, Alternative provider BCDR (Option C) provides additional safety by ensuring that you have a backup plan in case your primary provider fails.

This refers to using the disaster recovery solutions provided by the same cloud provider where the resources are running. This is typically the best option as it ensures seamless integration, compatibility, and the use of optimized tools and services designed specifically for that cloud environment. Cloud providers often offer robust BCDR solutions with high availability, scalability, and automated failover capabilities.

In this context "remote provider", "alternate provider", "primary provider" mean non cloud providers. So think renting space in a data center to move your workloads and storage to for BCDR. That would almost never make sense. The only option that makes sense is B. You can still choose a different cloud service provider to move your workloads too in that example.

uh.. I'll take the OBVIOUS free correct answer. Need more of these on my exam. Source: Verifying each answer against Chat GPT, my experience, other test banks, a written book, and weighing in the discussion from all users to create a 100% accurate guide for myself before I take the exam. (It isn't easy because of the time needed, but it is doing my diligence)

When resources are running in a cloud environment, the BEST disaster recovery solution is typically the Cloud provider BCDR (Business Continuity and Disaster Recovery) option, which is option B.
