Question 126

For this question, refer to the Dress4Win case study. You are responsible for the security of data stored in
Cloud Storage for your company, Dress4Win. You have already created a set of Google Groups and
assigned the appropriate users to those groups. You should use Google best practices and implement the
simplest design to meet the requirements.
Considering Dress4Win's business and technical requirements, what should you do?

Enable default storage encryption before storing files in Cloud Storage.

B.Assign custom IAM roles to the Google Groups you created in order to enforce security requirements.
Encrypt data with a customer-supplied encryption key when storing files in Cloud Storage.

C.Assign predefined IAM roles to the Google Groups you created in order to enforce security
requirements. Ensure that the default Cloud KMS key is set before storing files in Cloud Storage.

D.Assign predefined IAM roles to the Google Groups you created in order to enforce security
requirements. Utilize Google's default encryption at rest when storing files in Cloud Storage.

Question 127

You have an App Engine application that needs to be updated. You want to test the update with production traffic before replacing the current application version.
What should you do?

A.Deploy the update using the Instance Group Updater to create a partial rollout, which allows for canary testing.

B.Deploy the update as a new version in the App Engine application, and split traffic between the new and current versions.

C.Deploy the update in a new VPC, and use Google's global HTTP load balancing to split traffic between the update and current applications.

D.Deploy the update as a new App Engine application, and use Google's global HTTP load balancing to split traffic between the new and current applications.

Question 128

For this question, refer to the Dress4Win case study.
At Dress4Win, an operations engineer wants to create a tow-cost solution to remotely archive copies of database backup files. The database files are compressed tar files stored in their current data center. How should he proceed?

A.Create a cron script using gsutil to copy the files to a Coldline Storage bucket.

B.Create a cron script using gsutil to copy the files to a Regional Storage bucket.

C.Create a Cloud Storage Transfer Service Job to copy the files to a Coldline Storage bucket.

D.Create a Cloud Storage Transfer Service job to copy the files to a Regional Storage bucket.

Question 129

Your company is moving 75 TB of data into Google Cloud. You want to use Cloud Storage and follow Googlerecommended practices. What should you do?

A.Move your data onto a Transfer Appliance. Use a Transfer Appliance Rehydrator to decrypt the data into Cloud Storage.

B.Move your data onto a Transfer Appliance. Use Cloud Dataprep to decrypt the data into Cloud Storage.

C.Install gsutil on each server that contains data. Use resumable transfers to upload the data into Cloud Storage.

D.Install gsutil on each server containing data. Use streaming transfers to upload the data into Cloud Storage.

Question 130

For this question, refer to the Dress4Win case study.
Dress4Win has end-to-end tests covering 100% of their endpoints. They want to ensure that the move to the cloud does not introduce any new bugs. Which additional testing methods should the developers employ to prevent an outage?

A.They should enable Google Stackdriver Debugger on the application code to show errors in the code.

B.They should add additional unit tests and production scale load tests on their cloud staging environment.

C.They should run the end-to-end tests in the cloud staging environment to determine if the code is working as intended.

D.They should add canary tests so developers can measure how much of an impact the new release causes to latency.

Correct Answer: B

Topic 5, Dress4Win Case 2
Company Overview
Dress4win is a web-based company that helps their users organize and manage their personal wardrobe using a website and mobile application. The company also cultivates an active social network that connects their users with designers and retailers. They monetize their services through advertising, e-commerce, referrals, and a freemium app model. The application has grown from a few servers in the founder's garage to several hundred servers and appliances in a collocated data center. However, the capacity of their infrastructure is now insufficient for the application's rapid growth. Because of this growth and the company's desire to innovate faster. Dress4Win is committing to a full migration to a public cloud.
Solution Concept
For the first phase of their migration to the cloud, Dress4win is moving their development and test environments. They are also building a disaster recovery site, because their current infrastructure is at a single location. They are not sure which components of their architecture they can migrate as is and which components they need to change before migrating them.
Existing Technical Environment
The Dress4win application is served out of a single data center location. All servers run Ubuntu LTS v16.04.
Databases:
MySQL. 1 server for user data, inventory, static data:
- MySQL 5.8
- 8 core CPUs
- 128 GB of RAM
- 2x 5 TB HDD (RAID 1)
Redis 3 server cluster for metadata, social graph, caching. Each server is:
- Redis 3.2
- 4 core CPUs
- 32GB of RAM
Compute:
40 Web Application servers providing micro-services based APIs and static content.
- Tomcat - Java
- Nginx
- 4 core CPUs
- 32 GB of RAM
20 Apache Hadoop/Spark servers:
- Data analysis
- Real-time trending calculations
- 8 core CPUS
- 128 GB of RAM
- 4x 5 TB HDD (RAID 1)
3 RabbitMQ servers for messaging, social notifications, and events:
- 8 core CPUs
- 32GB of RAM
Miscellaneous servers:
- Jenkins, monitoring, bastion hosts, security scanners
- 8 core CPUs
- 32GB of RAM
Storage appliances:
iSCSI for VM hosts
Fiber channel SAN - MySQL databases
- 1 PB total storage; 400 TB available
NAS - image storage, logs, backups
- 100 TB total storage; 35 TB available
Business Requirements
Build a reliable and reproducible environment with scaled parity of production.
Improve security by defining and adhering to a set of security and Identity and Access Management (IAM) best practices for cloud.
Improve business agility and speed of innovation through rapid provisioning of new resources.
Analyze and optimize architecture for performance in the cloud.
Technical Requirements
Easily create non-production environment in the cloud.
Implement an automation framework for provisioning resources in cloud.
Implement a continuous deployment process for deploying applications to the on-premises datacenter or cloud.
Support failover of the production environment to cloud during an emergency.
Encrypt data on the wire and at rest.
Support multiple private connections between the production data center and cloud environment.
Executive Statement
Our investors are concerned about our ability to scale and contain costs with our current infrastructure. They are also concerned that a competitor could use a public cloud platform to offset their up-front investment and free them to focus on developing better features. Our traffic patterns are highest in the mornings and weekend evenings; during other times, 80% of our capacity is sitting idle.
Our capital expenditure is now exceeding our quarterly projections. Migrating to the cloud will likely cause an initial increase in spending, but we expect to fully transition before our next hardware refresh cycle. Our total cost of ownership (TCO) analysis over the next 5 years for a public cloud strategy achieves a cost reduction between 30% and 50% over our current model.
