Common Questions About the Google Cloud Certified - Professional Cloud Network Engineer Exam

Google Cloud Certified - Professional Cloud Network Engineer Sample Questions:

Question 1

Your company offers a popular gaming service. Your instances are deployed with private IP addresses, and external access is granted through a global load balancer. You believe you have identified a potential malicious actor, but aren't certain you have the correct client IP address. You want to identify this actor while minimizing disruption to your legitimate users.
What should you do?

A. Create a Cloud Armor Policy rule that denies traffic and review necessary logs.
B. Create a VPC Firewall rule that denies traffic, enable logging and set enforcement to enabled, and review necessary logs.
C. Create a Cloud Armor Policy rule that denies traffic, enable preview mode, and review necessary logs.
D. Create a VPC Firewall rule that denies traffic, enable logging and set enforcement to disabled, and review necessary logs.

Question 2

You are creating an instance group and need to create a new health check for HTTP(s) load balancing.
Which two methods can you use to accomplish this? (Choose two.)

A. Create a new health check using the VPC Network section in the GCP Console.
B. Create a new health check using the gcloud command line tool.
C. Create a new health check, or select an existing one, when you complete the load balancer's backend configuration in the GCP Console.
D. Create a new legacy health check using the gcloud command line tool.
E. Create a new legacy health check using the Health checks section in the GCP Console.

Question 3

You recently noticed a recurring daily spike in network usage in your Google Cloud project. You need to identify the virtual machine (VM) instances and type of traffic causing the spike in traffic utilization while minimizing the cost and management overhead required. What should you do?

A. Configure Packet Mirroring to send all traffic to a VM. Use Wireshark on the VM to identity traffic utilization for each VM in the VPC.
B. Enable Firewall Rules Logging for all allowed traffic and send the output to BigQuery for analysis.
C. Deploy a third-party network appliance and configure it as the default gateway. Use the third-party network appliance to identify users with high network traffic.
D. Enable VPC Flow Logs and send the output to BigQuery for analysis.

Question 4

Your company has defined a resource hierarchy that includes a parent folder with subfolders for each department. Each department defines their respective project and VPC in the assigned folder and has the appropriate permissions to create Google Cloud firewall rules. The VPCs should not allow traffic to flow between them. You need to block all traffic from any source, including other VPCs, and delegate only the intra-VPC firewall rules to the respective departments. What should you do?

A. Create two hierarchical firewall policies per department's folder with two rules in each: a high-priority rule that matches traffic from the private CIDRs assigned to the respective VPC and sets the action to goto_next, and another lower-priority rule that blocks traffic from any other source.
B. Create a VPC firewall rule in each VPC to block traffic from any source, with priority 0.
C. Create two hierarchical firewall policies per department's folder with two rules in each: a high-priority rule that matches traffic from the private CIDRs assigned to the respective VPC and sets the action to allow, and another lower-priority rule that blocks traffic from any other source.
D. Create a VPC firewall rule in each VPC to block traffic from any source, with priority 1000.

Question 5

You are the network administrator responsible for hybrid connectivity at your organization. Your developer team wants to use Cloud SQL in the us-west1 region in your Shared VPC. You configured a Dedicated Interconnect connection and a Cloud Router in us-west1, and the connectivity between your Shared VPC and on-premises data center is working as expected. You just created the private services access connection required for Cloud SQL using the reserved IP address range and default settings. However, your developers cannot access the Cloud SQL instance from on-premises. You want to resolve the issue. What should you do?

A. Create an additional Cloud Router in us-west2.
Create a new Border Gateway Protocol (BGP) peering connection to your on-premises data center.
Modify the VPC Network Peering connection used for Cloud SQL, and enable the import and export of routes.
B. Modify the VPC Network Peering connection used for Cloud SQL, and enable the import and export of routes.
Create a custom route advertisement in your Cloud Router to advertise the Cloud SQL IP address range.
C. Change the VPC routing mode to global.
Create a custom route advertisement in your Cloud Router to advertise the Cloud SQL IP address range.
D. Change the VPC routing mode to global.Modify the VPC Network Peering connection used for Cloud SQL, and enable the import and export of routes.
