CompTIA Cloud+ (CV0-003) — Question 19

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?

Answer options

• A. Create two /25 subnets in different regions.
• B. Create three /25 subnets in different regions.
• C. Create two /26 subnets in different regions.
• D. Create three /26 subnets in different regions.
• E. Create two /27 subnets in different regions.
• F. Create three /27 subnets in different regions.

Correct answer: A

Explanation

The correct answer, A, provides two /25 subnets, which allows for a sufficient number of IP addresses (126 usable) to accommodate the required 60 nodes and five reserved addresses per subnet. Options B, C, D, E, and F do not meet the capacity needs, as they either provide insufficient IP addresses or do not maximize high availability across regions.
