NEW QUESTION # 61
You are deploying an application that runs on Compute Engine instances. You need to determine how to expose your application to a new customer You must ensure that your application meets the following requirements
* Maps multiple existing reserved external IP addresses to the Instance
* Processes IP Encapsulating Security Payload (ESP) traffic
What should you do?
- A. Configure a target instance, and create a protocol forwarding rule for each external IP address to be mapped to the instance.
- B. Configure a target pool, and create protocol forwarding rules for each external IP address.
- C. Configure a backend service, and create an external network load balancer for each external IP address
- D. Configure the Compute Engine Instances' network Interface external IP address from None to Ephemeral Add as many external IP addresses as required
Answer: A
Explanation:
The correct answer is C. Configure a target instance, and create a protocol forwarding rule for each external IP address to be mapped to the instance.
This answer is based on the following facts:
A target instance is a Compute Engine instance that handles traffic from one or more forwarding rules1. You can use target instances to forward traffic to a single VM instance from one or more external IP addresses2.
A protocol forwarding rule specifies the IP protocol and port range for the traffic that you want to forward3. You can use protocol forwarding rules to forward traffic of any IP protocol, including ESP4.
The other options are not correct because:
Option A is not possible. You cannot create protocol forwarding rules for a target pool. A target pool is a group of instances that receives traffic from a network load balancer5.
Option B is not suitable. You do not need to create an external network load balancer for each external IP address. An external network load balancer distributes traffic among multiple backend instances based on the destination IP address and port. You can use a single load balancer with multiple forwarding rules to map multiple external IP addresses to the same backend service.
Option D is not feasible. You cannot add multiple external IP addresses to a single network interface of a Compute Engine instance. Each network interface can have only one external IP address that is either ephemeral or static. You can use alias IP ranges to assign multiple internal IP addresses to a single network interface, but not external IP addresses.
NEW QUESTION # 62
You configured a single IPSec Cloud VPN tunnel for your organization to a third-party customer. You confirmed that the VPN tunnel is established; however, the BGP session status states that BGP is not configured. The customer has provided you with their BGP settings:
* Local BGP address: 169.254.11.1/30
* Local ASN: 64515
* Peer BGP address: 169.254.11.2
* Peer ASN: 64517
* Base MED: 1000
* MD5 Authentication: Disabled
You need to configure the local BGP session for this tunnel based on the settings provided by the customer.
You already associated the Cloud Router with the Cloud VPN Tunnel. What settings should you use for the BGP session?
- A. Peer ASN: 64515
Advertised Route Priority (MED): 100
Local BGP IP: 169.254.11.2
Peer BGP IP: 169.254.11.1
MD5 Authentication: Disabled - B. Peer ASN: 64515

Peer BGP IP: 169.254.11.2
MD5 Authentication: Disabled - C. Peer ASN: 64517
Advertised Route Priority (MED): 100
Local BGP IP: 169.254.11.2
Peer BGP IP: 169.254.11.1
MD5 Authentication: Disabled - D. Peer ASN: 64515
Advertised Route Priority (MED): 1000
Local BGP IP: 169.254.11.2
Peer BGP IP: 169.254.11.1
MD5 Authentication: Enabled
Answer: C
Explanation:
Explanation: The correct configuration requires setting the Peer ASN as 64517 (as this is the ASN of the third-party customer). The local and peer BGP IP addresses should also be set correctly based on the provided information, and MD5 authentication should be disabled. The route priority should be set to 100 to reflect standard behavior.
NEW QUESTION # 63
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.

NEW QUESTION # 65
Your company is planning a migration to Google Kubernetes Engine. Your application team informed you that they require a minimum of 60 Pods per node and a maximum of 100 Pods per node Which Pod per node CIDR range should you use?
- A. /24
- B. /28
- C. /26
- D. /25
Answer: D
Explanation:
The correct answer is B. /25.
This answer is based on the following facts:
The Pod per node CIDR range determines the size of the IP address range that is assigned to each node for Pods1. The Pods that run on a node are allocated IP addresses from the node's assigned CIDR range1.
The size of the CIDR range corresponds to the maximum number of Pods per node. For example, a /24 CIDR range allows up to 256 IP addresses, but the default maximum number of Pods per node for Standard clusters is 1102. A /25 CIDR range allows up to 128 IP addresses, which is enough for 100 Pods per node.
The other options are not correct because:
Option A is too large. A /24 CIDR range allows more IP addresses than needed for 100 Pods per node. This could result in inefficient use of the IP address space and limit the number of nodes that can be created in the cluster.
Option C is too small. A /26 CIDR range allows only 64 IP addresses, which is not enough for 60 Pods per node. This could result in insufficient capacity to schedule Pods on the nodes.
Option D is also too small. A /28 CIDR range allows only 16 IP addresses, which is far below the minimum requirement of 60 Pods per node. This could result in Pod scheduling failures and poor performance.
NEW QUESTION # 66

NEW QUESTION # 67
Question:
You need to enable Private Google Access for some subnets within your Virtual Private Cloud (VPC). Your security team set up the VPC to send all internet-bound traffic back to the on-premises data center for inspection before egressing to the internet, and is also implementing VPC Service Controls for API-level security control. You have already enabled the subnets for Private Google Access. What configuration changes should you make to enable Private Google Access while adhering to your security team's requirements?
- A. Create a private DNS zone with a CNAME record for *.googleapis.com to private.googleapis.com, with an A record pointing to Google's private API address range.
Change the custom route that points the default route (0/0) to the default internet gateway as the next hop. - B. Create a private DNS zone with a CNAME record for *.googleapis.com to restricted.googleapis.com, with an A record pointing to Google's restricted API address range.Change the custom route that points the default route (0/0) to the default internet gateway as the next hop.
- C. Create a private DNS zone with a CNAME record for *.googleapis.com to private.googleapis.com, with an A record pointing to Google's private API address range.
Create a custom route that points Google's private API address range to the default internet gateway as the next hop. - D. Create a private DNS zone with a CNAME record for *.googleapis.com to restricted.googleapis.com, with an A record pointing to Google's restricted API address range.
Create a custom route that points Google's restricted API address range to the default internet gateway as the next hop.
Answer: B
Explanation:
For environments requiring API security controls, use restricted.googleapis.com as it restricts access to Google APIs and enforces VPC Service Controls. The custom DNS and routing configuration ensures compliance with security policies by directing all API traffic to restricted endpoints while maintaining Private Google Access.

NEW QUESTION # 68
Question:
Your organization has a subset of applications in multiple regions that require internet access. You need to control internet access from applications to URLs, including hostnames and paths. The compute instances that run these applications have an associated secure tag. What should you do?
- A. Deploy a Secure Web Proxy instance in each region. Apply a Secure Web Proxy policy to allow access from machines that match the secure tag to the URLs defined in a URL list.
- B. Deploy a single Secure Web Proxy instance with global access enabled. Apply a Secure Web Proxy policy to allow access from machines that match the secure tag to the URLs defined in a URL list.
- C. Deploy a Cloud NAT gateway. Use fully qualified domain name (FQDN) objects in the firewall policy rules to filter outgoing traffic to specific domains from machines that match a service account.
- D. Deploy a Cloud NAT gateway. Use fully qualified domain name (FQDN) objects in the firewall policy rules to filter outgoing traffic to specific domains from machines that match the secure tag.
Answer: B
Explanation:
To control internet access on a per-URL basis (including hostname and path), you should deploy Secure Web Proxy with global access enabled. The Secure Web Proxy will allow policy-based filtering of web traffic, allowing control over which URLs can be accessed based on the URL list defined in the policy. Unlike Cloud NAT, which does not support FQDN filtering, Secure Web Proxy is designed to provide such control, especially for scenarios with sensitive or controlled internet access requirements.
NEW QUESTION # 69
You are designing an IP address scheme for new private Google Kubernetes Engine (GKE) clusters, Due to IP address exhaustion of the RFC 1918 address space in your enterprise, you plan to use privately used public IP space for the new dusters. You want to follow Google-recommended practices, What should you do after designing your IP scheme?
- A. Create the minimum usable RFC 1918 primary and secondary subnet IP ranges for the clusters Re-use the secondary address range for the services across multiple private GKE clusters.
- B. Create privately used public IP primary and secondary subnet ranges for the clusters. Create a private GKE cluster With the following options selected and - siable-default-snat,--enable-ip-alias, and -enable-private-nodes
- C. Create privately used public IP primary and secondary subnet ranges for the clusters. Create a private GKE cluster With the following options selected: --enab1e-ip-a1ias and --enable-private-nodes.
- D. Create the minimum usable RFC 1918 primary and secondary subnet IP ranges for the clusters. Re-use the secondary address range for the pods across multiple private GKE clusters.
Answer: B
Explanation:
The correct answer is D. Create privately used public IP primary and secondary subnet ranges for the clusters. Create a private GKE cluster with the following options selected: --disable-default-snat, --enable-ip-alias, and --enable-private-nodes.
This answer is based on the following facts:
Privately used public IP (PUPI) addresses are any public IP addresses not owned by Google that a customer can use privately on Google Cloud1. You can use PUPI addresses for GKE pods and services in private clusters to mitigate address exhaustion.
A private GKE cluster is a cluster that has no public IP addresses on the nodes2. You can use private clusters to isolate your workloads from the public internet and enhance security.
The --disable-default-snat option disables source network address translation (SNAT) for the cluster3. This option allows you to use PUPI addresses without conflicting with other public IP addresses on the internet.
The --enable-ip-alias option enables alias IP ranges for the cluster4. This option allows you to use separate subnet ranges for nodes, pods, and services, and to specify the size of those ranges.
The --enable-private-nodes option enables private nodes for the cluster5. This option ensures that the nodes have no public IP addresses and can only communicate with other Google Cloud resources in the same VPC network or peered networks.
The other options are not correct because:
Option A is not suitable. Creating RFC 1918 primary and secondary subnet IP ranges for the clusters does not solve the problem of address exhaustion. Re-using the secondary address range for pods across multiple private GKE clusters can cause IP conflicts and routing issues.
Option B is also not suitable. Creating RFC 1918 primary and secondary subnet IP ranges for the clusters does not solve the problem of address exhaustion. Re-using the secondary address range for services across multiple private GKE clusters can cause IP conflicts and routing issues.
Option C is not feasible. Creating privately used public IP primary and secondary subnet ranges for the clusters is a valid step, but creating a private GKE cluster with only --enable-ip-alias and --enable-private-nodes options is not enough. You also need to disable default SNAT to avoid IP conflicts with other public IP addresses on the internet.

NEW QUESTION # 74
Your organization is deploying a single project for 3 separate departments. Two of these departments require network connectivity between each other, but the third department should remain in isolation. Your design should create separate network administrative domains between these departments. You want to minimize operational overhead.
How should you design the topology?
- A. Create 3 separate VPCs, and use VPC peering to establish connectivity between the two appropriate VPCs.
- B. Create a Shared VPC Host Project and the respective Service Projects for each of the 3 separate departments.
- C. Create a single project, and deploy specific firewall rules. Use network tags to isolate access between the departments.
- D. Create 3 separate VPCs, and use Cloud VPN to establish connectivity between the two appropriate VPCs.
Answer: B
Explanation:
Use Shared VPC to connect to a common VPC network. Resources in those projects can communicate with each other securely and efficiently across project boundaries using internal IPs. You can manage shared network resources, such as subnets, routes, and firewalls, from a central host project, enabling you to apply and enforce consistent network policies across the projects.
With Shared VPC and IAM controls, you can separate network administration from project administration. This separation helps you implement the principle of least privilege. For example, a centralized network team can administer the network without having any permissions into the participating projects. Similarly, the project admins can manage their project resources without any permissions to manipulate the shared network.

2. Add the VPC as a spoke and configure an export include policy to advertise only 192.168.1.0/24,
192.168.2.0/24, and 192.168.3.0/24 to the hub.
3. Enable global dynamic routing to allow resources in us-westl, us-centrall and asia-southeastl to reach the on-premises location through us-east4.
Answer: C
Explanation:
The key requirements are: limited IP space (192.168.0.0/20), reaching on-premises (172.16.0.0/16) from multiple Google Cloud regions (us-west1, europe-central1, asia-southeast1), and minimizing IP addresses used. The Cloud Interconnect connection to on-premises is in us-east4.
Minimize IP addresses and centralized NAT: Since all traffic to on-premises will traverse the Cloud Interconnect in us-east4, it's most efficient to configure a single Private NAT gateway instance in us-east4.
This allows resources from other regions to egress to on-premises through this single NAT gateway, using a minimal NAT subnet (192.168.1.0/24 in this case), thus conserving the limited 192.168.0.0/20 IP space.
Network Connectivity Center Spoke Export Policy: The VPC spoke needs to advertise the NAT subnet to the Network Connectivity Center hub. An export include policy is used to specify which routes (in this case, the
192.168.1.0/24 NAT subnet) should be advertised to the hub.
Global Dynamic Routing: To allow resources in us-west1, europe-central1, and asia-southeast1 to reach the on-premises location through the us-east4 Cloud Interconnect and NAT gateway, the VPC containing these resources (the spoke VPC) must have global dynamic routing enabled. This ensures that routes learned in one region (like the on-premises routes via us-east4) are available to VMs in all other regions of that VPC.
Options A and B configure Private NAT gateways in multiple regions, which consumes more IP addresses than necessary given that the Cloud Interconnect is only in us-east4. Option D uses 172.16.x.x for NAT subnets, which clashes with the on-premises IP range and the requirement to use the 192.168.0.0/20 space for cloud.
Exact Extract:
"Private NAT allows instances with private IP addresses in one VPC network to connect to on-premises or other cloud networks through a NAT IP address in a different region or network."
"To allow VMs in multiple regions to reach a central destination through a NAT gateway located in a specific region, you must configure global dynamic routing on the VPC network. This ensures that routes to the NAT gateway's subnet are propagated across all regions."
"When using Network Connectivity Center spokes, you can use export policies to control which routes are advertised from a spoke to the hub. An include policy specifies the exact prefixes to advertise."Reference:

NEW QUESTION # 80
You are planning to use Terraform to deploy the Google Cloud infrastructure for your company The design must meet the following requirements
* Each Google Cloud project must represent an Internal project that your team Will work on
* After an internal project is finished, the infrastructure must be deleted
* Each Internal project must have Its own Google Cloud project owner to manage the Google Cloud resources-
* You have 10-100 projects deployed at a time,
While you are writing the Terraform code, you need to ensure that the deployment IS Simple, and the code IS reusable With centralized management What should you doo
- A. Create a Shared VPC and service project for each Internal project
- B. Create a Single pt0Ject and additional VPCs for each Internal project
- C. Create a Single Project and Single VPC for each internal project
- D. Create a single Shared VPC and attach each Google Cloud project as a service project
Answer: D
Explanation:
The correct answer is C. Create a single Shared VPC and attach each Google Cloud project as a service project.
This answer is based on the following facts:
A Shared VPC allows you to share one or more VPC networks across multiple Google Cloud projects1. This simplifies the deployment and management of the network infrastructure, as you only need to create and maintain one VPC network for all your internal projects.
A Shared VPC consists of a host project that owns the VPC network and one or more service projects that use the VPC network2. You can attach and detach service projects as needed, depending on the lifecycle of your internal projects. You can also delete service projects without affecting the host project or other service projects.
A Shared VPC allows you to delegate administrative roles to different project owners3. You can grant the Shared VPC Admin role to the owner of the host project, who can manage the VPC network and its subnets. You can also grant the Service Project Admin role to the owners of the service projects, who can manage the Google Cloud resources in their own projects.
The other options are not correct because:
Option A is not suitable. Creating a single project and additional VPCs for each internal project will increase the complexity and cost of the network infrastructure. You will need to create and maintain multiple VPC networks, firewall rules, routes, and VPN tunnels. You will also have a limit on the number of VPC networks per project4.
Option B is not feasible. Creating a single project and single VPC for each internal project will not meet the requirement of having separate project owners for each internal project. You will have only one project owner who can manage all the Google Cloud resources in the same project.
Option D is not optimal. Creating a Shared VPC and service project for each internal project will not meet the requirement of having a simple and reusable code with centralized management. You will need to create and maintain multiple Shared VPCs, which will increase the complexity and cost of the network infrastructure. You will also have more Terraform code to write and manage for each Shared VPC.
NEW QUESTION # 81
Question:
Your multi-region VPC has had a long-standing HA VPN configured in "region 1" connected to your corporate network. You are planning to add two 10 Gbps Dedicated Interconnect connections and VLAN attachments in "region 2" to connect to the same corporate network. You need to plan for connectivity between your VPC and corporate network to ensure that traffic uses the Dedicated Interconnect connections as the primary path and the HA VPN as the secondary path. What should you do?
- A. Enable global dynamic routing mode on the VPC. Configure BGP associated with the HA VPN in
"region 1" to use a base priority value of 20000. Configure BGP associated with the VLAN attachments to use a base priority of 100. Configure your on-premises routers to use similar multi-exit discriminator (MED) values. - B. Enable global dynamic routing mode on the VPC. Configure BGP associated with the HA VPN in
"region 1" to use a base priority value of 100. Configure BGP associated with the VLAN attachments to use a base priority of 20000. Configure your on-premises routers to use similar multi-exit discriminator (MED) values. - C. Enable regional dynamic routing mode on the VPC. Configure BGP associated with the HA VPN in
"region 1" to use a base priority value of 100. Configure BGP associated with the VLAN attachments to use a base priority of 20000. Configure your on-premises routers to use similar multi-exit discriminator (MED) values. - D. Enable regional dynamic routing mode on the VPC. Configure BGP associated with the HA VPN in
"region 1" to use a base priority value of 20000. Configure BGP associated with the VLAN attachments to use a base priority of 100. Configure your on-premises routers to use similar multi-exit discriminator (MED) values.
Answer: B
Explanation:
For the Dedicated Interconnect to be the primary connection over the HA VPN, you should:
Enable global dynamic routing mode to allow the VPC to distribute routes dynamically across regions.
Set the BGP priority for the VLAN attachments associated with the Dedicated Interconnect to a lower base priority (e.g., 100) than the HA VPN's priority (e.g., 20000) to ensure it is preferred.
Setting up global dynamic routing with adjusted BGP priorities on both Interconnect and VPN will allow dynamic routing of traffic based on set preferences and path attributes, such as MED and priority levels. This setup ensures the Dedicated Interconnect, with a lower priority value, becomes the primary path for traffic, while the HA VPN, with a higher priority, serves as a backup.
