Question 1

You configured Cloud VPN with dynamic routing via Border Gateway Protocol (BGP). You added a custom route to advertise a network that is reachable over the VPN tunnel. However, the on-premises clients still cannot reach the network over the VPN tunnel. You need to examine the logs in Cloud Logging to confirm that the appropriate routers are being advertised over the VPN tunnel. Which filter should you use in Cloud Logging to examine the logs?

Options :

A : resource.type= “gce_router”

B : resource.type= “gce_network_region”

C : resource.type= “vpn_tunnel”

D : resource.type= “vpn_gateway”

Answer: C

Question 2

Your organization wants to deploy HA VPN over Cloud Interconnect to ensure encryption-in-transit over the Cloud Interconnect connections. You have created a Cloud Router and two encrypted VLAN attachments that have a 5 Gbps capacity and a BGP configuration. The BGP sessions are operational. You need to complete the deployment of the HA VPN over Cloud Interconnect. What should you do?

Options :

A : Create an HA VPN gateway and associate the gateway with your two encrypted VLAN attachments. Configure the HA VPN Cloud Router, peer VPN gateway resources, and HA VPN tunnels. Use the same encrypted Cloud Router used for the Cloud Interconnect tier.

B : Enable MACsec for Cloud Interconnect on the VLAN attachments.

C : Enable MACsec on Partner Interconnect.

D : Create an HA VPN gateway and associate the gateway with your two encrypted VLAN attachments. Create a new dedicated HA VPN Cloud Router, peer VPN gateway resources, and HA VPN tunnels.

Answer: A

Question 3

Your organization recently exposed a set of services through a global external Application Load Balancer. After conducting some testing, you observed that responses would intermittently yield a non-HTTP 200 response. You need to identify the error. What should you do? (Choose 2 answers)

Options :

A : Access a VM in the VPC through SSH, and try to access a backend VM directly. If the request is successful from the VM, increase the quantity of backends.

B : Enable and review the health check logs. Review the error responses in Cloud Logging.

C : Validate the health of the backend service. Enable logging on the load balancer, and identify the error response in Cloud Logging. Determine the cause of the error by reviewing the statusDetails log field.

D : Delete the load balancer and backend services. Create a new passthrough Network Load Balancer. Configure a failover group of VMs for the backend.

E : Validate the health of the backend service. Enable logging for the backend service, and identify the error response in Cloud Logging. Determine the cause of the error by reviewing the statusDetails log field.

Answer: B,C

Question 4

You are configuring load balancing for a standard three-tier (web, application, and database) application. You have configured an external HTTP(S) load balancer for the web servers. You need to configure load balancing for the application tier of servers. What should you do?

Options :

A : Configure a forwarding rule on the existing load balancer for the application tier.

B : Configure equal cost multi-path routing on the application servers.

C : Configure a new internal HTTP(S) load balancer for the application tier.

D : Configure a URL map on the existing load balancer to route traffic to the application tier.

Answer: A

Question 5

You just finished your company’s migration to Google Cloud and configured an architecture with 3 Virtual Private Cloud (VPC) networks: one for Sales, one for Finance, and one for Engineering. Every VPC contains over 100 Compute Engine instances, and now developers using instances in the Sales VPC and the Finance VPC require private connectivity between each other. You need to allow communication between Sales and Finance without compromising performance or security. What should you do?

Options :

A : Configure an HA VPN gateway between the Finance VPC and the Sales VPC.

B : Configure the instances that require communication between each other with an external IP address.

C : Create a VPC Network Peering connection between the Finance VPC and the Sales VPC.

D : Configure Cloud NAT and a Cloud Router in the Sales and Finance VPCs.
