Question 1 of 30

Time left: 00:00

You are designing an IPv4 addressing plan for a multinational enterprise. The company has four major regions, and each region has several sites. The core routing table must remain small and stable as new sites are added. Which addressing strategy best supports this requirement?

Select one option.

Assign random /24 networks to each VLAN from any available private IPv4 range
Allocate a contiguous IPv4 block per region, then allocate site and VLAN subnets from inside each regional block
Use one large flat subnet per region and rely on DHCP exclusions
Assign public IPv4 addresses to all internal VLANs
Allocate the smallest possible subnet to every VLAN without reserving spare capacity
