Google Cloud Certified - Professional Cloud Network Engineer Sample Questions (Q149-Q154):

NEW QUESTION # 149
You are responsible for designing a new connectivity solution between your organization's on-premises data center and your Google Cloud Virtual Private Cloud (VPC) network Currently, there Is no end-to-end connectivity. You must ensure a service level agreement (SLA) of 99.99% availability What should you do?

A. Use a Direct Peering connection between your on-premises data center and Google Cloud. Configure Classic VPN with two tunnels and one Cloud Router.
B. Use one Dedicated Interconnect connection in a single metropolitan area. Configure one Cloud Router and enable global routing in the VPC.
C. Use HA VPN. Configure one tunnel from each Interface of the VPN gateway to connect to the corresponding interfaces on the peer gateway on-premises. Configure one Cloud Router and enable global routing in the VPC.
D. Use two Dedicated Interconnect connections in a single metropolitan area. Configure one Cloud Router and enable global routing in the VPC.

Answer: C

Explanation:
For Dedicated Interconnects: At least four Dedicated Interconnect connections, two connections in one metropolitan area (metro) and two connections in another metro. Connections that are in the same metro must be placed in different edge availability domains (metro availability zones) to achieve 99.99% availability.
For HA VPN:
HA VPN to peer VPN gateways Connect an HA VPN gateway to one or two separate peer VPN devices
99.99%
HA VPN between two Google Cloud networks Connect two Google Cloud VPC networks in a single region by using an HA VPN gateway in each network 99.99%

NEW QUESTION # 150
You built a web application with several containerized microservices. You want to run those microservices on Cloud Run. You must also ensure that the services are highly available to your customers with low latency. What should you do?

A. Deploy the Cloud Run services to multiple regions. Configure a round-robin A record in Cloud DNS.
B. Deploy the Cloud Run services to multiple availability zones. Create a global TCP load balancer. Add the Cloud Run endpoints to its backend service.
C. Deploy the Cloud Run services to multiple regions. Create serverless network endpoint groups (NEGs) that point to the services. Create a global HTTPS load balancer, and attach the serverless NEGs as backend services of the load balancer.
D. Deploy the Cloud Run services to multiple availability zones. Create Cloud Endpoints that point to the services. Create a global HTTPS load balancer, and attach the Cloud Endpoints to its backend

Answer: C

NEW QUESTION # 151
Your organization recently re-architected your cloud environment to use Network Connectivity Center.
However, an error occurred when you tried to add a new VPC named vpc-dev as a spoke. The error indicated that there was an issue with an existing spoke and the IP space of a VPC named vpc-pre-prod. You must complete the migration quickly and efficiently. What should you do?

A. Exclude the conflicting IP range by using the --exclude-export-ranges flag when creating the VPC spoke for vpc-dev.
B. Exclude the conflicting IP range by using the --exclude-export-ranges flag in the hub when attaching the VPC spoke for vpc-dev.
C. Delete the VMs associated with the conflicting subnets, then delete the conflicting subnets in vpc-dev.
Recreate the subnets with a new IP range and redeploy the previously deleted VMs in the new subnets.
Add the VPC spoke for vpc-dev.
D. Remove the conflicting VPC spoke for vpc-pre-prod from the set of VPC spokes in Network Connectivity Center. Add the VPC spoke for vpc-dev. Add the previously removed vpc-pre-prod as a VPC spoke.

Answer: D

Explanation:
Explanation: The most efficient way to resolve the conflict is to temporarily remove the conflicting vpc-pre- prod spoke, add the vpc-dev spoke, and then re-add vpc-pre-prod. This ensures that the migration happens quickly without the need to change IP ranges or delete resources.

NEW QUESTION # 152
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 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.
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 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.

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.

NEW QUESTION # 153
You are responsible for designing a new connectivity solution for your organization's enterprise network to access and use Google Workspace. You have an existing Shared VPC with Compute Engine instances in us-west1. Currently, you access Google Workspace via your service provider's internet access. You want to set up a direct connection between your network and Google. What should you do?

A. Order a Carrier Peering connection in the same metropolitan area. Configure a Border Gateway Protocol (BGP) session between Google and your router.
B. Order a Dedicated Interconnect connection in the same metropolitan area. Create a VLAN attachment, a Cloud Router in us-west1, and a Border Gateway Protocol (BGP) session between your Cloud Router and your router.
C. Order a Direct Peering connection in the same metropolitan area. Configure a Border Gateway Protocol (BGP) session between Google and your router.
D. Configure HA VPN in us-west1. Configure a Border Gateway Protocol (BGP) session between your Cloud Router and your on-premises data center.

Answer: C

Explanation:
Direct Peering exists outside of Google Cloud. Unless you need to access Google Workspace applications, the recommended methods of access to Google Cloud are Dedicated Interconnect or Partner Interconnect.
