Exam 350-901 topic 1 question 271 discussion

D is the answer. A would be for cross-zone configuration

This is a poorly-written question and open to interpretation. I am interpreting "cross-region cloud" to mean a public cloud provider with multiple regions, and you are deploying your services in multiple regions. Within a region, public cloud providers have multiple availability zones. If you don't have a DR or geographic latency requirement dictating multiple regions, you can operate within a single region and use multiple availability zones. And that's great for most scenarios, as long as there isn't a large-scale outage that impacts all zones in a region (weather event that prevents fuel resupply to generators like a Hurricane Katrina event, war/conflict, meteor strike). However, even then, public cloud providers have been known to have services fail across multiple zones in a region. It's rare, and usually due to a design error that wasn't caught prior, but it happens from time to time. So some public cloud customers want to have DR capability to fail over to a different geographic region.

I feel like it could be A or D, but in my opinion A just feels more correct as the question refers to High Availability but D is talking about Disaster Recovery. While this doesn't make D wrong, it just feels slightly less relevant than A. I think this is another crappy Cisco question intended to confuse :/

according to ChatGPT. D is the correct answer. ^_^ When an application is designed that requires high availability, what is a reason to use a cross-region cloud? A. Account for failure in another zone. B. Minimize costs. C. Protect from a single component failure. D. Provide disaster recovery protection. Answer: D. Provide disaster recovery protection. why isn't A correct? A cross-region cloud can account for failure in another zone, but it is not the primary purpose of using a cross-region cloud. why isn't B correct? Minimizing costs is not the primary purpose of using a cross-region cloud. why isn't C correct? Protecting from a single component failure is not the primary purpose of using a cross-region cloud. how accurate would you rate your answer for this question? I would rate my answer as completely accurate.
