Objective 2.3
ACEPlanning and implementing networking resources
Objective 2.3 sits in Planning and implementing a cloud solution, which carries 30% of the Associate Cloud Engineer exam. The questions below are original, written from the official objective title above, and each explanation cites the Google Cloud page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
An engineer asks whether one subnet can serve virtual machines in two different regions. What scope do VPC networks and subnets have?
Correct.
Concept
A network is an addressing namespace and a subnet is a block of addresses that has to be reachable at low latency. The first can span the planet; the second is pinned to where its hardware sits.
Why C
VPC networks are global resources, and each one consists of one or more subnets, which are regional resources holding the IP address ranges.
Now you: objective 2.3 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
A team wants the smallest subnet range Google Cloud will accept. What is the longest IPv4 subnet mask allowed?
Sample question 2 of 3
An engineer has run out of addresses in an existing subnet. What can be done with its primary IPv4 range?
Sample question 3 of 3
A team wants two subnets both named production inside one VPC network. When does Google Cloud permit that?
