west1). Data must be written to both regions concurrently with low latency and high
consistency. Which database should be chosen?

Probably A here because changing IPs to avoid overlap is the cleanest fix long term. NAT can get messy and firewalls or route blocking won't solve the core problem of overlapping CIDRs.

Maybe B makes the most sense here since NAT can translate those overlapping IPs without needing a full network redesign or blocking routes, which might cause connectivity issues.

D imo, blocking conflicting IPs at firewall level stops traffic confusion without renumbering.

It’s B because NAT is designed specifically to handle overlapping IP ranges by translating them, which avoids the need to renumber everything or block routes that you might actually need.

B/C? Blocking overlapping IP space with routes or firewalls won’t solve the root issue since traffic would still be confused about where to go. NAT (option B) seems like a practical way to translate those overlapping IPs so they don’t clash, allowing both networks to communicate. Readdressing everything like in A seems like a huge effort and not always feasible after the fact. So, B feels more realistic for integration without massive changes.

This one’s tricky since overlapping IPs are a pain. I’d go with A because it talks about applying new IP addresses to avoid conflicts altogether. Option A.
