Question 1

In your Google Cloud organization, you have two folders: Dev and Prod. You want a scalable and consistent way to enforce the following firewall rules for all virtual machines (VMs) with minimal cost:

Port 8080 should always be open for VMs in the projects in the Dev folder.

Any traffic to port 8080 should be denied for all VMs in your projects in the Prod folder.

What should you do?

ACreate and associate a firewall policy with the Dev folder with a rule to open port 8080. Create and associate a firewall policy with the Prod folder with a rule to deny traffic to port 8080.

BCreate a Shared VPC for the Dev projects and a Shared VPC for the Prod projects. Create a VPC firewall rule to open port 8080 in the Shared VPC for Dev. Create a firewall rule to deny traffic to port 8080 in the Shared VPC for Prod. Deploy VMs to those Shared VPCs.

CIn all VPCs for the Dev projects, create a VPC firewall rule to open port 8080. In all VPCs for the Prod projects, create a VPC firewall rule to deny traffic to port 8080.

DUse Anthos Config Connector to enforce a security policy to open port 8080 on the Dev VMs and deny traffic to port 8080 on the Prod VMs.

Correct answer: A

Question 2

You want to configure a NAT to perform address translation between your on-premises network blocks and GCP.

Which NAT solution should you use?

ACloud NAT

BAn instance with IP forwarding enabled

CAn instance configured with iptables DNAT rules

DAn instance configured with iptables SNAT rules

Correct answer: A

Question 3

You are configuring the firewall endpoints as part of the Cloud Next Generation Firewall (Cloud NGFW) intrusion prevention service in Google Cloud. You have configured a threat prevention security profile, and you now need to create an endpoint for traffic inspection. What should you do?

AAttach the profile to the VPC network, create a firewall endpoint within the zone, and use a firewall policy rule to apply the L7 inspection.

BCreate a firewall endpoint within the zone, associate the endpoint to the VPC network, and use a firewall policy rule to apply the L7 inspection.

CCreate a firewall endpoint within the region, associate the endpoint to the VPC network, and use a firewall policy rule to apply the L7 inspection.

DCreate a Private Service Connect endpoint within the zone, associate the endpoint to the VPC network, and use a firewall policy rule to apply the L7 inspection.

Correct answer: C

For Cloud NGFW in Google Cloud, firewall endpoints are typically created at the regional level, allowing you to associate these with your VPC network for Layer 7 traffic inspection. This regional setup ensures high availability and scales the inspection service across the network.

Question 4

You have the following Shared VPC design VPC Flow Logs is configured for Subnet-1 In the host VPC. You also want to monitor flow logs for Subnet-2. What should you do?

AConfigure a firewall rule to permit Subnet-2 IP addresses outbound in the host protect VPC.

BConfigure Packet Mirroring in both the host and service project VPCs.

CConfigure a VPC Flow Logs filter for Subnet-2 in the host project VPC.

DConfigure VPC Flow Logs in the service project VPC for Subnet-2.

Correct answer: D

Understanding VPC Flow Logs:

VPC Flow Logs is a feature that captures information about the IP traffic going to and from network interfaces in a VPC. It helps in monitoring and analyzing network traffic, ensuring security, and optimizing network performance.

Current Configuration:

According to the diagram, VPC Flow Logs is already configured for Subnet-1 in the host VPC. This means that traffic information for Subnet-1 is being captured and logged.

Requirement for Subnet-2:

The goal is to monitor flow logs for Subnet-2, which is in the service project VPC.

Correct Configuration for Subnet-2:

To monitor the flow logs for Subnet-2, you need to configure VPC Flow Logs within the service project VPC where Subnet-2 resides. This is because VPC Flow Logs must be configured in the same project and VPC where the subnet is located.

Implementation Steps:

Go to the Google Cloud Console.

Navigate to the service project where Subnet-2 is located.

Select the VPC network containing Subnet-2.

Enable VPC Flow Logs for Subnet-2 by editing the subnet settings and enabling the flow logs option.

Cost and Performance Considerations:

Enabling VPC Flow Logs may incur additional costs based on the volume of data logged. Ensure to review and understand the pricing implications.

Analyze and manage the data collected to avoid unnecessary logging and costs.

Shared VPC Overview

By configuring VPC Flow Logs in the service project VPC for Subnet-2, you ensure that traffic data is correctly captured and monitored, adhering to Google Cloud's best practices.

Question 5

Your company's logo is published as an image file across multiple websites that are hosted by your company You have implemented Cloud CDN, however, you want to improve the performance of the cache hit ratio associated with this image file. What should you do?

AConfigure custom cache keys for the backend service that holds the image file, and clear the Host and Protocol checkboxes-

BConfigure Cloud Storage as a custom origin backend to host the image file, and select multi-region as the location type

CConfigure versioned IJRLs for each domain to serve users the *mage file before the cache entry expires

DConfigure the default time to live (TTL) as O for the image file.

Correct answer: A

This answer meets the requirement of improving the performance of the cache hit ratio associated with the image file. The reason is:

Custom cache keys allow you to control which parts of the request URL are used to build the cache key.The cache key is a unique identifier that Cloud CDN uses to store and retrieve cached content1.

By default, Cloud CDN uses the complete request URL, including the protocol (http or https) and the host (the domain name), to build the cache key.This means that if the same image file is requested from different domains or protocols, Cloud CDN will cache multiple copies of it, which reduces the cache hit ratio1.

By clearing the Host and Protocol checkboxes, you can tell Cloud CDN to ignore these parts of the request URL when building the cache key.This way, Cloud CDN will cache only one copy of the image file, regardless of which domain or protocol it is requested from, which improves the cache hit ratio1.

Option B is incorrect because configuring Cloud Storage as a custom origin backend does not affect the cache hit ratio. It only affects how Cloud CDN retrieves the content from the origin if it is not cached. Option C is incorrect because configuring versioned URLs for each domain does not improve the cache hit ratio. It actually worsens it, because it creates more variations of the request URL that Cloud CDN has to cache separately. Option D is incorrect because configuring the default TTL as 0 for the image file means that Cloud CDN will not cache it at all, which defeats the purpose of using Cloud CDN.
