Definitely need multiple instances to handle that load!

Wait, can you really achieve 99.999% availability with just one node?

I’m a bit confused about the configurations; I know 'nam3' is a multi-regional option, but I can't recall if it's the best choice for this scenario.

I practiced a similar question where we had to consider latency and availability, and I feel like having multiple instances in different regions might be the right approach.

I think creating a cluster with at least 3 Spanner nodes could help with availability, but I’m not entirely confident if that’s enough for 99.999%.

I remember something about multi-regional configurations being important for high availability, but I'm not sure which one to choose.

Okay, let's see here. I'm a bit unsure about the difference between "multitenant service" and "multiple instances." I'll need to think through those carefully.

Based on my understanding of environmental regulations, I believe the correct answer is A - Publicly available. The EPA would likely want this information to be accessible.

The correct answer is definitely C. The investigator's primary duty is to create a backup of the original evidence without disturbing it. That's the most important step in the investigation process.

This seems straightforward enough. The passage states that the routing algorithm can evenly distribute the data, leading to better performance and load balancing. So the correct answer should be the one that reflects those benefits.
