Exam N10-009 Topic 4 Question 136 Discussion

Actual exam question for CompTIA's N10-009 exam
Question #: 136
Topic #: 4
A network administrator needs to connect two routers in a point-to-point configuration and conserve IP space. Which of the following subnets should the administrator use?

Suggested Answer: D Vote an answer

Using a /30 subnet mask is the most efficient way to conserve IP space for a point-to-point connection between two routers. A /30 subnet provides four IP addresses, two of which can be assigned to the router interfaces, one for the network address, and one for the broadcast address. This makes it ideal for point-to-point links where only two usable IP addresses are needed.
Reference: CompTIA Network+ study materials and subnetting principles.
