CompTIA Cloud+ (CV0-003) — Question 209

A cloud architect is reviewing the design for a new cloud-based ERP solution. The solution consists of eight servers with a single network interface. The allocated
IP range is 172.16.0.0/28. One of the requirements of the solution is that it must be able to handle the potential addition of 16 new servers to the environment.
Because of the complexity of the firewall and related ACL requirements, these new servers will need to be in the same network range. Which of the following changes would allow for the potential server addition?

Answer options

• A. Change the IP address range to use a 10.0.0.0 address.
• B. Change the server template to add network interfaces.
• C. Change the subnet mask to use a 255.255.255.128 range.
• D. Change the server scaling configuration to increase the maximum limit.

Correct answer: C

Explanation

Changing the subnet mask to 255.255.255.128 allows for a larger range of IP addresses, accommodating the addition of 16 more servers. The original /28 subnet can only support 16 IPs, which is insufficient for the new requirement. The other options do not address the need for additional IP addresses within the existing network range.
