You have 32 GB of data in a single file that you need to upload to a Nearline Storage bucket. The WAN connection you are using is rated at 1 Gbps, and you are the only one on the connection. You want to use as match of the rated 1 Gbps as possible to transfer the file rapidly. How should you upload the file?

• A.Change the storage class of the bucket from Nearline to Multi-Regional.
• B.Use the GCP Console to transfer the file instead of gsutil.
• C.Decrease the TCP window size on the machine initiating the transfer.
• D.Enable parallel composite uploads using gsutil on the file transfer.

A retail company has sensors placed in its physical retail stores. The sensors send messages over HTTP when customers interact with in-store product displays. A Solutions Architect needs to implement a system for processing those sensor messages; the results must be available for the Data Analysis team.
Which architecture should be used to meet these requirements?

• A.Implement an Amazon API Gateway to server as the HTTP endpoint. Have the API Gateway trigger an AWS Lambda function to process the messages, and save the results to an Amazon DynamoDB table.
• B.Use AWS Direct Connect to connect sensors to DynamoDB so that data can be written directly to a DynamoDB table where it can be accessed by the Data Analysis team.
• C.Create an Amazon EC2 instance to server as the HTTP endpoint and to process the messages. Save the results to Amazon S3 for the Data Analysis team to download.
• D.Use Amazon Route 53 to direct incoming sensor messages to a Lambda function to process the message and save the results to a Amazon DynamoDB table.

You want to configure autohealing for network load balancing for a group of Compute Engine instances that run in multiple zones, using the fewest possible steps. You need to configure re-creation of VMs if they are unresponsive after 3 attempts of 10 seconds each. What should you do?

• A.Create an HTTP load balancer with a backend configuration that references an existing instance group. Define a balancing mode and set the maximum RPS to 10.
• B.Create a managed instance group. Set the Autohealing health check to healthy (HTTP).
• C.Create an HTTP load balancer with a backend configuration that references an existing instance group. Set the health check to healthy (HTTP).
• D.Create a managed instance group. Verify that the autoscaling setting is on.

You have several users who need access to some very specific Google Cloud functionality. You'd like to follow the principle of least privilege. What's the best way to ensure these users can list Cloud Storage buckets, list BigQuery jobs, and list compute disks?

• A.Create a custom role for this job role, add the required permissions, and add the users to the role.
• B.Add the users to a group, apply the Cloud Storage Bucket Viewer, BigQuery Job User, and Compute User predefined roles.
• C.Use the Cloud Storage Bucket Viewer, BigQuery Job User, and Compute User predefined roles.
• D.Add the users to the viewer role.

You want to run a single caching HTTP reverse proxy on GCP for a latency-sensitive website. This specific reverse proxy consumes almost no CPU. You want to have a 30-GB in-memory cache, and need an additional 2 GB of memory for the rest of the processes. You want to minimize cost. How should you run this reverse proxy?

• A.Package it in a container image, and run it on Kubernetes Engine, using n1-standard-32 instances as nodes.
• B.Run it on Compute Engine, and choose a custom instance type with 6 vCPUs and 32 GB of memory.
• C.Run it on Compute Engine, choose the instance type n1-standard-1, and add an SSD persistent disk of 32 GB.
• D.Create a Cloud Memorystore for Redis instance with 32-GB capacity.
