* Communication between applications within an environment may be necessary.
* Network administrators should centrally manage all network resources, including subnets, routes, and firewall rules.
* Each application should be billed separately.
* Developers of an application within a project should have the autonomy to create their compute resources.
* Up to 1000 applications are expected per environment.
What should you do?
- A. Create a design that has one host project with a Shared VPC for the production environment, another host project with a Shared VPC for the non-production environment, and a service project that is associated with the corresponding host project for each initiative.
- B. Create a design that implements a single Shared VPC. Use VPC firewall rules with secure tags to enforce micro-segmentation between environments.
- C. Create a design that has a Shared VPC for each project. Implement hierarchical firewall policies to apply micro-segmentation between VPCs.
- D. Create a design where each project has its own VPC. Ensure all VPCs are connected by a Network Connectivity Center hub that is centrally managed by the network team.
Answer: A
Explanation:
Using separate Shared VPCs for production and non-production environments in different host projects (Option D) meets all requirements. This design allows network administrators to centrally manage resources within each Shared VPC while ensuring isolation between environments and separate billing. By associating service projects with each host project, developers can manage resources within their project without affecting the overall VPC network structure.
NEW QUESTION # 123
You have several VMs across multiple VPCs in your cloud environment that require access to internet endpoints. These VMs cannot have public IP addresses due to security policies, so you plan to use Cloud NAT to provide outbound internet access. Within your VPCs, you have several subnets in each region. You want to ensure that only specific subnets have access to the internet through Cloud NAT. You want to avoid any unintentional configuration issues caused by other administrators and align to Google-recommended practices. What should you do?
- A. Create a firewall rule in each VPC at priority 500 that targets all instances in the network and denies egress to the internet (0.0.0.0/0). Create a firewall rule at priority 300 that targets all instances in the network, has a source filter that maps to the allowed subnets, and allows egress to the internet (0.0.0.0
/0). Deploy Cloud NAT and configure a custom source range that includes the allowed subnets. - B. Create a firewall rule in each VPC at priority 500 that targets all instances in the network and denies egress to the internet (0.0.0.0/0). Create a firewall rule at priority 300 that targets all instances in the network, has a source filter that maps to the allowed subnets, and allows egress to the internet (0.0.0.0
/0). Deploy Cloud NAT and configure all primary and secondary subnet source ranges. - C. Create a constraints/compute.restrictCloudNATUsage organizational policy constraint. Attach the constraint to a folder that contains the associated projects. Configure the allowedValues to only contain the subnets that should have internet access. Deploy Cloud NAT and select only the allowed subnets.
- D. Deploy Cloud NAT in each VPC and configure a custom source range that includes the allowed subnets. Configure Cloud NAT rules to only permit the allowed subnets to egress through Cloud NAT.
Answer: C
Explanation:
Explanation: Using an organizational policy with the restrictCloudNATUsage constraint allows you to limit Cloud NAT usage to specific subnets, ensuring that only the necessary subnets can access the internet. This method aligns with Google-recommended practices for controlling Cloud NAT configurations across multiple VPCs and regions.
NEW QUESTION # 124
Question:
Your organization is deploying a mission-critical application with components in different regions due to strict compliance requirements. There are latency issues between different applications that reside in us- central1 and us-east4. The application team suspects the Google Cloud network as the source of the excessive latency despite using the Premium Network Service Tier. You need to use Google-recommended practices with the least amount of effort to verify the inter-region latency by investigating network performance. What should you do?
- A. Configure a VM with a probe in Network Intelligence Center in each zone for each region. Choose the traffic type (cross-zonal), metric (latency - RTT), desired regions (us-central1 and us-east4), and the network tier.
- B. Set up the Performance Dashboard in Network Intelligence Center. Select the traffic type (cross-zonal), the metric (latency - RTT), the time period, the desired regions (us-central1 and us-east4), and the network tier.
- C. Enable VPC Flow Logs for the VPC. Identify major bottlenecks from the application level using Flow Analyzer.
- D. Configure two Linux VMs in each zone for each region. Install the application, and run a load test using each zone from different regions.

NEW QUESTION # 126
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. You log in to a Compute Engine instance, try to resolve an on-premises hostname, and the query fails. DNS queries are not arriving at the on-premises DNS server. You need to use managed services to reconfigure Cloud DNS to resolve the DNS error. What should you do?
- A. Review the existing Cloud DNS zones, and validate that there is a route in the VPC directing traffic destined to the IP address of the DNS servers. Recreate the existing DNS forwarding zones to forward all queries to the on-premises DNS servers.
- B. Ensure that the operating systems of the Compute Engine instances are configured to send DNS queries to the on-premises DNS servers directly.
- C. Validate that there is network connectivity to the on-premises environment and that the Compute Engine instances can reach other on-premises resources. If errors persist, remove the VPC Network Peerings and recreate the peerings after validating the routes.
- D. Validate that the Compute Engine instances are using the Metadata Service IP address as their resolver. Configure an outbound forwarding zone for the on-premises domain pointing to the on-premises DNS server. Configure Cloud Router to advertise the Cloud DNS proxy range to the on-premises network.
Answer: D
Explanation:
To resolve DNS resolution issues for on-premises domains from Google Cloud, you should use Cloud DNS outbound forwarding zones. This setup forwards DNS requests for specific domains to on-premises DNS servers. Cloud Router is needed to advertise the range for the DNS proxy service back to the on-premises environment, ensuring that DNS queries from Compute Engine instances reach the on-premises DNS servers.
NEW QUESTION # 127
You are responsible for enabling Private Google Access for the virtual machine (VM) instances in your Virtual Private Cloud (VPC) to access Google APIs. All VM instances have only a private IP address and need to access Cloud Storage. You need to ensure that all VM traffic is routed back to your on-premises data center for traffic scrubbing via your existing Cloud Interconnect connection. However, VM traffic to Google APIs should remain in the VPC. What should you do?
- A. Configure your on-premises router to advertise 0.0.0.0/0 via Border Gateway Protocol (BGP) with a lower priority (MED) than the default VPC route.
Create a private Cloud DNS zone for googleapis.com, create a CNAME for * googieapis.com to private googleapis com, and create an A record for private.googleapis.com that resolves to the addresses in 199
.36.153.8/30.
Create a static route in your VPC for the range 199.36. 153.8/30 with the default internet gateway as the next hop. - B. Delete the default route in your VPC and configure your on-premises router to advertise 0.0.0.0/0 via Border Gateway Protocol (BGP).

NEW QUESTION # 128
Your organization is migrating workloads from AWS to Google Cloud. Because a particularly critical workload will take longer to migrate, you need to set up Google Cloud CDN and point it to the existing application at AWS. What should you do?
- A. Create a hybrid NEG that points to the existing IP of the application.
* Map the NEG to a passthrough Network Load Balancer as a target pool.
* Enable Cloud CDN on the target pool. - B. Create a hybrid NEG that points to the existing IP of the application.
* Map the NEG to an Application Load Balancer as a backend service.
* Enable Cloud CDN on the backend service. - C. Create an internet NEG that points to the existing FQDN of the application.
* Map the NEG to an Application Load Balancer as a backend service.
* Enable Cloud CDN on the backend service. - D. Create an internet NEG that points to the existing FQDN of the application.
* Map the NEG to a passthrough Network Load Balancer as a backend service.
* Enable Cloud CDN on the backend service.
Answer: C
Explanation:
To configure Cloud CDN for an application hosted outside of Google Cloud (e.g., in AWS), you need to use an internet network endpoint group (NEG). An internet NEG allows you to point to external endpoints using their FQDN or IP address. Cloud CDN works with external HTTP(S) Load Balancers, and you enable CDN on the backend service associated with the load balancer. A Network Load Balancer (passthrough) does not support Cloud CDN.
Exact Extract:
"To enable Cloud CDN for content hosted outside of Google Cloud, you must use an external HTTP(S) Load Balancer with an internet network endpoint group (NEG)."
"An internet NEG specifies one or more external endpoints that can be reached by an external HTTP(S) Load Balancer. You can specify endpoints using an IP address and port, or a fully qualified domain name (FQDN) and port."
"Cloud CDN is enabled on the backend service of an external HTTP(S) Load Balancer."Reference: Google Cloud CDN Documentation - Caching external content, Internet NEGs overview

NEW QUESTION # 132
You want Cloud CDN to serve the https://www.example.com/images/spacetime.png static image file that is hosted in a private Cloud Storage bucket, You are using the VSE ORIG.-X_NZADERS cache mode You receive an HTTP 403 error when opening the file In your browser and you see that the HTTP response has a Cache-control: private, max-age=O header How should you correct this Issue?
- A. Configure a Cloud Storage bucket permission that gives the Storage Legacy Object Reader role
- B. Increase the default time-to-live (TTL) for the backend service.
- C. Change the cache mode to cache all content.
- D. Enable negative caching for the backend bucket
Answer: A
Explanation:
The correct answer is A. Configure a Cloud Storage bucket permission that gives the Storage Legacy Object Reader role.
This answer is based on the following facts:
Cloud CDN can serve private content from Cloud Storage buckets, but you need to grant the appropriate permissions to the Google-managed service account that represents your load balancer1.
The Storage Legacy Object Reader role grants read access to objects in a bucket2.
The Cache-control: private header indicates that the object is not publicly readable and requires authentication3.
The USE_ORIGIN_HEADERS cache mode instructs Cloud CDN to cache responses based on the Cache-Control and Expires headers from the origin server4. Changing the cache mode, increasing the TTL, or enabling negative caching will not affect the 403 error.

NEW QUESTION # 136
You created a new VPC network named Dev with a single subnet. You added a firewall rule for the network Dev to allow HTTP traffic only and enabled logging. When you try to log in to an instance in the subnet via Remote Desktop Protocol, the login fails. You look for the Firewall rules logs in Stackdriver Logging, but you do not see any entries for blocked traffic. You want to see the logs for blocked traffic.
What should you do?
- A. Check the VPC flow logs for the instance.
- B. Create a new firewall rule to allow traffic from port 22, and enable logs.
- C. Create a new firewall rule with priority 65500 to deny all traffic, and enable logs.
- D. Try connecting to the instance via SSH, and check the logs.
Answer: C
Explanation:
Ingress packets in VPC Flow Logs are sampled after ingress firewall rules. If an ingress firewall rule denies inbound packets, those packets are not sampled by VPC Flow Logs. We want to see the logs for blocked traffic so we have to look for them in firewall logs. https://cloud.google.com/vpc/docs/flow-logs#key_properties
