1. A multinational organization is designing a new Google Cloud
environment that must support multiple application teams while
maintaining centralized control over networking, security, and IP
address management. The organization expects dozens of projects to
be added over time, and different teams must be isolated logically
while still sharing common network services. Which Google Cloud
networking architecture is generally most appropriate for this
requirement?
A. Create an independent VPC network in every project and manually
configure static routes between all projects.
B. Create a single auto mode VPC and place every workload in the default
subnets.
C. Use a Shared VPC architecture with a centrally administered host
,project and separate service projects for workloads.
D. Create a separate VPC for every workload and use Cloud NAT to connect
the VPCs.
The correct answer is C because Shared VPC allows centralized network
administration in a host project while service projects consume shared
subnets for their workloads. This model provides centralized governance
while preserving project-level separation for application teams.
2. A company wants complete control over the IP ranges assigned to
subnets because its Google Cloud environment must connect to an
existing enterprise network containing several RFC 1918 address
ranges. The networking team wants to prevent Google Cloud from
automatically selecting subnet ranges that could overlap with on-
premises networks. Which VPC configuration should be selected?
A. Auto mode VPC
B. Custom mode VPC
C. Default VPC
D. Serverless VPC
The correct answer is B because a custom mode VPC allows administrators
to explicitly create subnets and select their IP ranges. This provides the
control required to avoid address-space conflicts with existing networks.
, 3. An organization has two VPC networks that belong to separate Google
Cloud projects. The networks need private internal connectivity, and
the organization does not want traffic to traverse the public internet.
The teams also want to avoid deploying VPN appliances. Which Google
Cloud capability is most appropriate?
A. Cloud NAT
B. Cloud CDN
C. VPC Network Peering
D. Cloud Armor
The correct answer is C because VPC Network Peering provides private
connectivity between VPC networks using Google's network infrastructure
without requiring VPN appliances or public internet paths.
4. A network engineer is designing a Google Cloud VPC and needs to
provide connectivity from VMs to the internet while ensuring that the
VMs do not have external IP addresses. Which managed service
should be used?
A. Cloud CDN
B. Cloud DNS
C. Cloud NAT
D. VPC Network Peering
, The correct answer is C because Cloud NAT provides outbound internet
translation for eligible resources without requiring those resources to
possess external IP addresses. It does not provide unsolicited inbound
connectivity.
5. A security team wants a firewall policy that can be centrally
administered and applied consistently across multiple VPC networks in
an organization. The team wants to avoid maintaining independent
copies of equivalent firewall rules in every project. Which capability
should the team consider?
A. Cloud NAT
B. Hierarchical firewall policies
C. Cloud Router
D. VPC Network Peering
The correct answer is B because hierarchical firewall policies can be
associated with higher levels of the resource hierarchy and provide
centralized control over traffic policies across applicable VPC networks.
6. A company is deploying workloads in several regions and wants its VPC
to use explicitly selected subnet ranges rather than automatically
generated regional ranges. The networking team also expects to add
additional regions later. Which subnet design best supports this
requirement?
