Wait, are we really saying RTO/PRO define business continuity? That's wild!

D makes sense, higher tiers need stricter requirements.

I think C is the false one, not sure about that.

RTO is about recovery time, RPO is about data loss.

I’m a bit confused about B. I thought RPO was about time, not bits. Maybe that one is false?

I practiced a similar question, and I think D is definitely true because Tier 1 data centers usually have stricter requirements.

I’m not sure, but I think RTO and RPO are often confused. I feel like C could be misleading since mirroring might not always guarantee the best RTO/RPO.

I remember RTO is about how quickly we need to recover, while RPO is about how much data we can afford to lose. I think A might be the false one?

Hmm, I'm a bit confused by the fabric failover aspect. I'll need to make sure I understand how that works before I can decide on the right configuration.

Hmm, I'm a bit confused by the different namespace declarations in the options. I'll need to make sure I understand how namespaces work in XML before I can confidently select the right answer.

I'm a bit stumped on this one. The wording is a bit unclear, and I'm not sure I fully understand the context. But I'll give it my best shot and try to reason through the options.

Wait, is this asking about ZHDFS specifically? I'm not familiar with that, so I'll need to do some research before answering.
