As part of a network team managing the GCP VPC networks. The networks are either a custom VPC or auto-mode VPC. There is a design request to expand the IP range of the subnets in the auto-mode network.
What is the broadest prefix (subnet mask) that can be used?
A. /14
B. /15
C. /16
D. /17
Answer: C
Option A, B and D are incorrect, any prefix broader than /16 would conflict with the primary IP ranges of the other automatically created subnets.
Option C is correct. The subnet mask of auto-mode network subnets is /20 and it can be expanded to /16 without it conflicting with the range of other subnets
