質問 1：
(You are developing an internet of things (IoT) application that captures sensor data from multiple devices that have already been set up. You need to identify the global data storage product your company should use to store this data. You must ensure that the storage solution you choose meets your requirements of sub- millisecond latency. What should you do?)
A. Store the IoT data in Cloud Storage. Implement caching by using Cloud CDN.
B. Store the IoT data in Spanner. Use caches to speed up the process and avoid latencies.
C. Capture IoT data in BigQuery datasets.
D. Store the IoT data in Bigtable.

質問 2：
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)
A. Delete the load balancer and backend services. Create a new passthrough Network Load Balancer.
Configure a failover group of VMs for the backend.
B. 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.
C. Enable and review the health check logs. Review the error responses in Cloud Logging.
D. 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.
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.

質問 3：
You have applications running in the us-west1 and us-east1 regions. You want to build a highly available VPN that provides 99.99% availability to connect your applications from your project to the cloud services provided by your partner's project while minimizing the amount of infrastructure required. Your partner's services are also in the us-west1 and us-east1 regions. You want to implement the simplest solution. What should you do?
A. Create one OpenVPN Access Server in each region of your VPC and your partner's VPC. Connect your servers to the partner's servers.
B. Create one Cloud Router and one HA VPN gateway in the us-west1 region of your VPC. Create one OpenVPN Access Server in each region of your partner's VPC. Connect your VPN gateway to your partner's servers.
C. Create one Cloud Router and one HA VPN gateway in the us-west1 region of your VPC and your partner's VPC. Connect your VPN gateways to the partner's gateways with a pair of tunnels. Enable global dynamic routing in each VPC.
D. Create one Cloud Router and one HA VPN gateway in each region of your VPC and your partner's VPC. Connect your VPN gateways to the partner's gateways. Enable global dynamic routing in each VPC.
正解：D

質問 4：
Your company just completed the acquisition of Altostrat (a current GCP customer). Each company has a separate organization in GCP and has implemented a custom DNS solution. Each organization will retain its current domain and host names until after a full transition and architectural review is done in one year. These are the assumptions for both GCP environments.
* Each organization has enabled full connectivity between all of its projects by using Shared VPC.
* Both organizations strictly use the 10.0.0.0/8 address space for their instances, except for bastion hosts (for accessing the instances) and load balancers for serving web traffic.
* There are no prefix overlaps between the two organizations.
* Both organizations already have firewall rules that allow all inbound and outbound traffic from the 10.0.0.0
/8 address space.
* Neither organization has Interconnects to their on-premises environment.
You want to integrate networking and DNS infrastructure of both organizations as quickly as possible and with minimal downtime.
Which two steps should you take? (Choose two.)
A. Create a third organization with a new host project, and attach all projects from your company and Altostrat to it using shared VPC.
B. Set up some variant of DNS forwarding and zone transfers in each organization.
C. Provision Cloud Interconnect to connect both organizations together.
D. Connect VPCs in both organizations using Cloud VPN together with Cloud Router.
E. Use Cloud DNS to create A records of all VMs and resources across all projects in both organizations.

質問 5：
You are in the early stages of planning a migration to GCP. You want to test the functionality of your hybrid cloud design before you start to implement it in production. The design includes services running on a Compute Engine Virtual Machine instance that need to communicate to on-premises servers using private IP addresses. The on-premises servers have connectivity to the internet, but you have not yet established any Cloud Interconnect connections. You want to choose the lowest cost method of enabling connectivity between your instance and on-premises servers and complete the test in 24 hours.
Which connectivity method should you choose?
A. Dedicated Interconnect with a single VLAN attachment
B. Dedicated Interconnect, but don't provision any VLAN attachments
C. 50-Mbps Partner VLAN attachment
D. Cloud VPN
正解：D
