Google Cloud Certified - Professional Cloud Network Engineer Sample Questions (Q104-Q109):

NEW QUESTION # 104
Question:
Your organization is developing a landing zone architecture with the following requirements:
* No communication between production and non-production environments.
* 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 implements a single Shared VPC. Use VPC firewall rules with secure tags to enforce micro-segmentation between environments.
B. Create a design that has a Shared VPC for each project. Implement hierarchical firewall policies to apply micro-segmentation between VPCs.
C. 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.
D. 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.

Answer: D

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 # 105
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 the Compute Engine Instances' network Interface external IP address from None to Ephemeral Add as many external IP addresses as required
B. Configure a target instance, and create a protocol forwarding rule for each external IP address to be mapped to the instance.
C. Configure a target pool, and create protocol forwarding rules for each external IP address.
D. Configure a backend service, and create an external network load balancer for each external IP address

Answer: B

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 # 106
You are designing the networking infrastructure for your company on Google Cloud. Your design must connect three separate VPC networks for development, testing, and production to two on- premises data centers while remaining isolated from each other. Each data center is connected to Google Cloud via Cloud VPN.
Additionally, your design must incorporate a user-published security service that is hosted in another Google Cloud organization and made available for private consumption. You need to create a scalable and centrally managed solution.
What should you do?

A. Create a Shared VPC, and migrate the resources from the development, testing, and production VPCs into service projects.
B. Use VPC Network Peering to create a full mesh between the development, testing, and production VPCs and the Cloud VPN network.
C. Use Network Connectivity Center to establish a full-mesh topology between the three VPCs. Use VPC Network Peering to connect to the Cloud VPN and Private Service Connect to access the third-party service.
D. Create a Network Connectivity Center hub, and configure each of the three VPCs and the two Cloud VPN spokes. Use Private Service Connect to access the third-party service.

Answer: D

Explanation:
Network Connectivity Center is the scalable, centrally managed option for connecting multiple isolated VPCs and multiple on-premises sites through Cloud VPN using a hub-and-spoke model.
That fits the requirement to keep development, testing, and production as separate VPCs while centrally managing connectivity to the two data centers. For the user-published security service hosted in another Google Cloud organization and consumed privately, the correct pattern is Private Service Connect, which is designed for private consumption of published services across organizational boundaries.

NEW QUESTION # 107
You are designing a Partner Interconnect hybrid cloud connectivity solution with geo-redundancy across two metropolitan areas. You want to follow Google-recommended practices to set up the following region/metro pairs:
(region 1/metro 1)
(region 2/metro 2)
What should you do?

A. Create a Cloud Router in region 1 with one VLAN attachment connected to metro1-zone2-x.
Create a Cloud Router in region 2 with one VLAN attachment connected to metro2-zone2-x.
B. Create a Cloud Router in region 1 with one VLAN attachment connected to metro1-zone1-x.
Create a Cloud Router in region 2 with two VLAN attachments connected to metro2-zone2-x.
C. Create a Cloud Router in region 1 with one VLAN attachment connected to metro1-zone1-x and one VLAN attachment connected to metro1-zone2-x.Create a Cloud Router in region 2 with one VLAN attachment connected to metro2-zone1-x and one VLAN attachment to metro2-zone2-x.
D. Create a Cloud Router in region 1 with two VLAN attachments connected to metro1-zone1-x.
Create a Cloud Router in region 2 with two VLAN attachments connected to metro1-zone2-x.

Answer: B

NEW QUESTION # 108
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).
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.
C. 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).
Create a public Cloud DNS zone with a CNAME for *.google.com to private googleapis com, create a CNAME for * googleapis.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.
D. Delete the default route in your VPC.
Create a private Cloud DNS zone for googleapis.com, create a CNAME for *.googleapis.com to restricted googleapis.com, and create an A record for restricted googleapis com that resolves to the addresses in 199.36.153.4/30.
Create a static route in your VPC for the range 199.36.153.4/30 with the default internet gateway as the next hop.
