CompTIA Network+ (N10-009) — Question 461

A network technician needs to configure IP addressing in a Class С network with eight subnets total:

• Three for 60 hosts
• Three for 15 hosts
• Two for seven hosts

Which of the following solutions should the technician use to accomplish this task?

Answer options

• A. CIDR
• B. APIPA
• C. VLSM
• D. RFC 1918

Correct answer: C

Explanation

The correct solution is VLSM (Variable Length Subnet Masking), which allows for subnets of different sizes, making it ideal for accommodating the varying host requirements in this scenario. CIDR is more about summarizing routes rather than subnetting for specific host needs, APIPA is used for automatic addresses in the absence of a DHCP server, and RFC 1918 pertains to private IP address ranges, not subnetting strategies.
