Exam CV0-003 topic 1 question 156 discussion

Actual exam question from CompTIA's CV0-003

Question #: 156
Topic #: 1

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?

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.

Selected Answer: B

The current IP range (172.16.0.0/28) provides only 14 usable IPs (excluding network and broadcast addresses), which is not enough to accommodate an additional 16 servers. A /28 subnet allows for only 16 total addresses (14 usable). To support 24 servers (8 existing + 16 new) while keeping them in the same network, a larger subnet is needed. A /25 subnet (255.255.255.128) provides 128 total addresses, with 126 usable IPs, which is more than enough.

Selected Answer: C

Yes, it's overkill because the next subnet up at /27 would accommodate at 32 IPs (30 usable), but of the choices listed C does indeed work.
