Because you do not know every possible future use for the data TerraEarth collects, you have decided to build a system that captures and stores all raw data in case you need it later. How can you most cost-effectively accomplish this goal?

• Have the vehicles in the field stream the data directly into BigQuery.

• Have the vehicles in the field pass the data to Cloud Pub/Sub and dump it into a Cloud Dataproc cluster that stores data in Apache Hadoop Distributed File System (HDFS) on persistent disks.

• Have the vehicles in the field continue to dump data via FTP, adjust the existing Linux machines, and use a collector to upload them into Cloud Dataproc HDFS for storage.

• Have the vehicles in the field continue to dump data via FTP, and adjust the existing Linux machines to immediately upload it to Cloud Storage with gsutil.

Your company wants to try out the cloud with low risk. They want to archive approximately 100 TB of their log data to the cloud and test the analytics features available to them there, while also retaining that data as a long-term disaster recovery backup. Which two steps should they take?

• Load logs into BigQuery.

• Load logs into Cloud SQL.

• Import logs into Stackdriver.

• Insert logs into Cloud Bigtable.

• Upload log files into Cloud Storage.

The database administration team has asked you to help them improve the performance of their new database server running on Compute Engine. The database is used for importing and normalizing the company’s performance statistics. It is built with MySQL running on Debian Linux. They have an n1-standard-8 virtual machine with 80 GB of SSD zonal persistent disk. What should they change to get better performance from this system in a cost-effective manner?

• Increase the virtual machine’s memory to 64 GB.

• Create a new virtual machine running PostgreSQL.

• Dynamically resize the SSD persistent disk to 500 GB.

• Migrate their performance metrics warehouse to BigQuery.

Your organization has 5 TB of private data on premises. You need to migrate the data to Cloud Storage. You want to maximize the data transfer speed. How should you migrate the data?

• Use gsutil.

• Use gcloud.

• Use GCS REST API.

• Use Storage Transfer Service.

Your organization has a 3-tier web application deployed in the same network on Google Cloud Platform. Each tier (web, API, and database) scales independently of the others. Network traffic should flow through the web to the API tier, and then on to the database tier. Traffic should not flow between the web and the database tier. How should you configure the network?

• Add each tier to a different subnetwork.

• Set up software-based firewalls on individual VMs.

• Add tags to each tier and set up routes to allow the desired traffic flow

• Add tags to each tier and set up firewall rules to allow the desired traffic flow.

What is the back end of cloud computing?

• The third party company
• The personal computer user
• The internet
• Your personal home server

Your company wants to reduce cost on infrequently accessed data by moving it to the cloud. The data will still be accessed approximately once a month to refresh historical charts. In addition, data older than 5 years is no longer needed. How should you store and manage the data?

• In Google Cloud Storage and stored in a Multi-Regional bucket. Set an Object Lifecycle Management policy to delete data older than 5 years.

• In Google Cloud Storage and stored in a Multi-Regional bucket. Set an Object Lifecycle Management policy to change the storage class to Coldline for data older than 5 years.

• In Google Cloud Storage and stored in a Nearline bucket. Set an Object Lifecycle Management policy to delete data older than 5 years.

• In Google Cloud Storage and stored in a Nearline bucket. Set an Object Lifecycle Management policy to change the storage class to Coldline for data older than 5 years.

Your company’s architecture is shown in the diagram. You want to keep data in sync across Region 1 and Region 2. Which product should you use?
