CV0-003 Question #492: Real Exam Question with Answer & Explanation

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 imp

Cloud Architecture and Design

Question

A cloud architect is designing the VPCs for a new hybrid cloud deployment. The business requires the following: - High availability - Horizontal auto-scaling - 60 nodes peak capacity per region - Five reserved network IP addresses per subnet - /24 range Which of the following would BEST meet the above requirements?

Options

  • ACreate two /25 subnets in different regions
  • BCreate three /25 subnets in different regions
  • CCreate two /26 subnets in different regions
  • DCreate three /26 subnets in different regions
  • ECreate two /27 subnets in different regions
  • FCreate three /27 subnets in different regions

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
