The correct answer is A. Create two /25 subnets in different regions. HA is guaranteed through the horizontal scaling, allowing different subnets in different regions. With 60 nodes (IP addresses), you can count out the /26 (64 available IPs, when you need 5 IPs in reserve) and /27 (32 available IPs aren’t enough). And finally, it is physically…
Question

Explanation
HA is guaranteed through the horizontal scaling, allowing different subnets in different regions. With 60 nodes (IP addresses), you can count out the /26 (64 available IPs, when you need 5 IPs in reserve) and /27 (32 available IPs aren’t enough). And finally, it is physically impossible to create three /25 subnets due to IPs multiplying/dividing in increments of 2 (i.e., /25 = 128 and /24
