Google Cloud Certified - Professional Cloud Network Engineer Questions and Answers

Question 1

Question:

Your company's current network architecture has three VPC Service Controls perimeters:

    One perimeter (PERIMETER_PROD) to protect production storage buckets

    One perimeter (PERIMETER_NONPROD) to protect non-production storage buckets

    One perimeter (PERIMETER_VPC) that contains a single VPC (VPC_ONE)

In this single VPC (VPC_ONE), the IP_RANGE_PROD is dedicated to the subnets of the production workloads, and the IP_RANGE_NONPROD is dedicated to subnets of non-production workloads. Workloads cannot be created outside those two ranges. You need to ensure that production workloads can access only production storage buckets and non-production workloads can access only non-production storage buckets with minimal setup effort. What should you do?

Options:

A.

Develop a design that uses the IP_RANGE_PROD and IP_RANGE_NONPROD perimeters to create two access levels, with each access level referencing a single range. Create two ingress access policies with each access policy referencing one of the two access levels. Update the PERIMETER_PROD and PERIMETER_NONPROD perimeters.

B.

Develop a design that removes the PERIMETER_VPC perimeter. Update the PERIMETER_NONPROD perimeter to include the project containing VPC_ONE. Remove the PERIMETER_PROD perimeter.

C.

Develop a design that creates a new VPC (VPC_NONPROD) in the same project as VPC_ONE. Migrate all the non-production workloads from VPC_ONE to the PERIMETER_NONPROD perimeter. Remove the PERIMETER_VPC perimeter. Update the PERIMETER_PROD perimeter to include VPC_ONE and the PERIMETER_NONPROD perimeter to include VPC_NONPROD.

D.

Develop a design that removes the PERIMETER_VPC perimeter. Update the PERIMETER_PROD perimeter to include the project containing VPC_ONE. Remove the PERIMETER_NONPROD perimeter.

Question 2

Your company has recently installed a Cloud VPN tunnel between your on-premises data center and your Google Cloud Virtual Private Cloud (VPC). You need to configure access to the Cloud Functions API for your on-premises servers. The configuration must meet the following requirements:

Certain data must stay in the project where it is stored and not be exfiltrated to other projects.

Traffic from servers in your data center with RFC 1918 addresses do not use the internet to access Google Cloud APIs.

All DNS resolution must be done on-premises.

The solution should only provide access to APIs that are compatible with VPC Service Controls.

What should you do?

Options:

A.

Create an A record for private.googleapis.com using the 199.36.153.8/30 address range.

Create a CNAME record for *.googleapis.com that points to the A record.

Configure your on-premises routers to use the Cloud VPN tunnel as the next hop for the addresses you used in the A record.

Remove the default internet gateway from the VPC where your Cloud VPN tunnel terminates.

B.

Create an A record for restricted.googleapis.com using the 199.36.153.4/30 address range.

Create a CNAME record for *.googleapis.com that points to the A record.

Configure your on-premises routers to use the Cloud VPN tunnel as the next hop for the addresses you used in the A record.

Configure your on-premises firewalls to allow traffic to the restricted.googleapis.com addresses.

C.

Create an A record for restricted.googleapis.com using the 199.36.153.4/30 address range.

Create a CNAME record for *.googleapis.com that points to the A record.

Configure your on-premises routers to use the Cloud VPN tunnel as the next hop for the addresses you used in the A record.

Remove the default internet gateway from the VPC where your Cloud VPN tunnel terminates.

D.

Create an A record for private.googleapis.com using the 199.36.153.8/30 address range.

Create a CNAME record for *.googleapis.com that points to the A record.

Configure your on-premises routers to use the Cloud VPN tunnel as the next hop for the addresses you used in the A record.

Configure your on-premises firewalls to allow traffic to the private.googleapis.com addresses.

Question 3

Your organization is running out of private IPv4 IP addresses. You need to create a new design pattern to reduce IP usage in your Google Kubernetes Engine clusters. Each new GKE cluster should have a unique /24 range of routable RFC1918 IP addresses. What should you do?

Options:

A.

Q Configure NAT by using the IP masquerading agent in the GKE cluster.

B.

Q Share the primary and secondary ranges between multiple clusters.

C.

Q Use dual stack IPv4/IPv6 clusters, and assign IPv6 ranges for Pods and Services.

D.

Q Configure the secondary ranges outside the RFC1918 space, or use privately used public IPs.
