Professional-Cloud-Network-Engineer exam is available in English and Japanese and can be taken at any of the authorized testing centers worldwide.

NO.65 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.

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.

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.

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.

NO.66 Your company’s security team wants to limit the type of inbound traffic that can reach your web servers to protect against security threats. You need to configure the firewall rules on the web servers within your Virtual Private Cloud (VPC) to handle HTTP and HTTPS web traffic for TCP only. What should you do?

Create an allow on match ingress firewall rule with the target tag “web-server” to allow all IP addresses for TCP port 80.

Create an allow on match egress firewall rule with the target tag “web-server” to allow all IP addresses for TCP port 80.

Create an allow on match ingress firewall rule with the target tag “web-server” to allow all IP addresses for TCP ports 80 and 443.

Create an allow on match egress firewall rule with the target tag “web-server” to allow web server IP addresses for TCP ports 60 and 443.

NO.67 You have setup a shared VPC and you have created three projects; Host Project, Service Project-1 and Service Project-2. You have created two subnets, subnet-1 in us-west1 and subnet-
2 in us-central1 in the Host Project. Only subnet-1 has been shared with Service Project -1 but when you go to VPC networks in Service Project-1 you also see subnet-2 which hasn’t been shared with Service Project-1. Please select the correct option from below why is subnet-2 available to Service Project-1. Note Host Project is the Host Project in the shared VPC, Service Project-1 and Service project-2 are the Service Projects in the shared VPC.

The current user has Shared VPC Admin role and with Shared VPC Admin role all the networks are available.

It is a bug in Google Cloud, please report it.

By default all subnets are available.

Remove Shared Network admin role to the current user.

NO.68 You create a Google Kubernetes Engine private cluster and want to use kubectl to get the status of the pods. In one of your instances you notice the master is not responding, even though the cluster is up and running.
What should you do to solve the problem?

Assign a public IP address to the instance.

Create a route to reach the Master, pointing to the default internet gateway.

Create the appropriate firewall policy in the VPC to allow traffic from Master node IP address to the instance.

Assign each user the editor role.

Assign each user the compute.networkAdmin role.

Give each user the following permissions only: compute.interconnectAttachments.create, compute.interconnectAttachments.get.

Give each user the following permissions only: compute.interconnectAttachments.create, compute.interconnectAttachments.get, compute.routers.create, compute.routers.get, compute.routers.update.

NO.70 You are disabling DNSSEC for one of your Cloud DNS-managed zones. You removed the DS records from your zone file, waited for them to expire from the cache, and disabled DNSSEC for the zone. You receive reports that DNSSEC validating resolves are unable to resolve names in your zone.
What should you do?

Update the TTL for the zone.

Set the zone to the TRANSFER state.

Disable DNSSEC at your domain registar.

Transfer ownership of the domain to a new registar.

NO.71 You need to create a GKE cluster in an existing VPC that is accessible from on-premises. You must meet the following requirements:
IP ranges for pods and services must be as small as possible.
The nodes and the master must not be reachable from the internet.
You must be able to use kubectl commands from on-premises subnets to manage the cluster.
How should you create the GKE cluster?

* Create a private cluster that uses VPC advanced routes.
* Set the pod and service ranges as /24.
* Set up a network proxy to access the master.

* Create a VPC-native GKE cluster using GKE-managed IP ranges.
* Set the pod IP range as /21 and service IP range as /24.
* Set up a network proxy to access the master.

* Create a VPC-native GKE cluster using user-managed IP ranges.

NO.72 Your company has a Virtual Private Cloud (VPC) with two Dedicated Interconnect connections in two different regions: us-west1 and us-east1. Each Dedicated Interconnect connection is attached to a Cloud Router in its respective region by a VLAN attachment. You need to configure a high availability failover path. By default, all ingress traffic from the on-premises environment should flow to the VPC using the us-west1 connection. If us-west1 is unavailable, you want traffic to be rerouted to us-east1. How should you configure the multi-exit discriminator (MED) values to enable this failover path?

Use regional routing. Set the us-east1 Cloud Router to a base priority of 100, and set the us-west1 Cloud Router to a base priority of 1

Use global routing. Set the us-east1 Cloud Router to a base priority of 100, and set the us-west1 Cloud Router to a base priority of 1

Use regional routing. Set the us-east1 Cloud Router to a base priority of 1000, and set the us-west1 Cloud Router to a base priority of 1

Use global routing. Set the us-east1 Cloud Router to a base priority of 1000, and set the us-west1 Cloud Router to a base priority of 1

NO.73 You are using a third-party next-generation firewall to inspect traffic. You created a custom route of 0.0.0.0/0 to route egress traffic to the firewall. You want to allow your VPC instances without public IP addresses to access the BigQuery and Cloud Pub/Sub APIs, without sending the traffic through the firewall.
Which two actions should you take? (Choose two.)

Create a set of custom static routes to send traffic to the internal IP addresses of Google APIs and services via the default internet gateway.

NO.74 You are configuring the final elements of a migration effort where resources have been moved from on-premises to Google Cloud. While reviewing the deployed architecture, you noticed that DNS resolution is failing when queries are being sent to the on-premises environment.

Ensure that the operating systems of the Compute Engine instances are configured to send DNS queries to the on-premises DNS servers directly.

NO.75 You have created a firewall with rules that only allow traffic over HTTP, HTTPS, and SSH ports. While testing, you specifically try to reach the server over multiple ports and protocols; however, you do not see any denied connections in the firewall logs. You want to resolve the issue.
What should you do?
