I believe option B is also not valid because the primary instance is in a different fault domain than the secondary instances.

Haha, option D is like putting all your eggs in one basket, except the basket is on fire. Not a great idea for a high-availability system.

I agree with Son, C is the way to go. Gotta spread those instances across those availability and fault domains, yo!

I agree with Leana, having all instances in the same fault domain is not a good high-availability setup.

C is the correct answer. Placing all instances in the same availability domain defeats the purpose of having a highly available system.

Option B seems off, having the primary instance and a secondary instance in the same fault domain doesn't sound like a high-availability setup to me.

It's important to distribute instances across different fault domains for better reliability.

Option B is definitely not a valid placement for a high-availability DB system.

I agree, having primary and secondary instances in the same fault domain is risky.
