the case studies before the exam to save time while taking the text. You don't need to memorize the case studies, as you'll have access to them during the test. Watch for numbers that indicate the scale of the problem. For example, if you need 10 Gbps, then you should consider a Cloud Interconnect solution over a VPN solution, which works up to about 3 Gbps for each VPN tunnel.
Understand what is needed in the near term and what may be needed in the future. For example, we don't have specific MLOps workflows in the TerramEarth case study. Initially, predictions may be based only on structured data, but some vehicles may have cameras to create images of machine components or the operating environment. In the future, there may be an opportunity to use images of operating environments to automatically detect a problem in the environment that could damage the vehicle. In that case, AutoML Vision Edge may be useful for performing image classification in real time. This requirement is not stated, and not even implied, but it is the kind of planning for the future that architects are expected to do.
Understand how to plan a migration. Migrations are high-risk operations. Data can be lost, and services may be unavailable. Know how to plan to run new and old systems in parallel so that you can compare results. Be able to identify lower-risk migration steps so that they can be scheduled first. Plan for incremental migrations.
Know agile software development practices. You won't have to write code for this exam, but you will need to understand continuous integration/continuous delivery and how to maintain development, test, staging, and production environments. Understand what is meant by an infrastructure-as-code service and how that helps accelerate development and deployment.
Keep in mind that solutions may involve non-Google services or applications. Google has many services, but sometimes the best solution involves a third-party solution. For example, Jenkins and Spinnaker are widely used tools to support continuous integration and deployment. Google Cloud has a code repository, but many developers use GitHub. Sometimes businesses are locked into existing solutions, such as a third-party database. The business may want to migrate to another database solution, but the cost may be too high for the foreseeable future.
Review Questions
1 You have been tasked with interviewing line-of-business owners about their needs for a new cloud application. Which of the following do you expect to find?A comprehensive list of defined business and technical requirementsThat their business requirements do not have a one-to-one correlation with technical requirementsBusiness and technical requirements in conflictClear consensus on all requirements
2 You have been asked by stakeholders to suggest ways to reduce operational expenses as part of a cloud migration project. Which of the following would you recommend?Managed services, preemptible machines, access controlsManaged services, preemptible machines, autoscalingNoSQL databases, preemptible machines, autoscalingNoSQL databases, preemptible machines, access controls
3 Some executives are questioning your recommendation to employ continuous integration/continuous delivery (CI/CD). What reasons would you give to justify your recommendation?CI/CD supports small releases, which are easier to debug and enable faster feedback.CI/CD is used only with preemptible machines and therefore saves money.CI/CD fits well with waterfall methodology but not agile methodologies.CI/CD limits the number of times code is released.
4 The finance director has asked your advice about complying with a document retention regulation. What kind of service-level objective (SLO) would you recommend to ensure that the finance director will be able to retrieve sensitive documents for at least the next seven years? When a document is needed, the finance director will have up to seven days to retrieve it. The total storage required will be approximately 100 TB.High availability SLODurability SLOReliability SLOScalability SLO
5 You are facilitating a meeting of business and technical managers to solicit requirements for a cloud migration project. The term incident comes up several times. Some of the business managers are unfamiliar with this term in the context of IT. How would you describe an incident?A disruption in the ability of a DevOps team to complete work on timeA disruption in the ability of the business managers to approve a project plan on schedule A disruption that causes a service to be degraded or unavailableA personnel problem on the DevOps team
6 You have been asked to consult on a cloud migration project that includes moving private medical information to a storage system in the cloud. The project is for a company in the United States. What regulation would you suggest that the team review during the requirements-gathering stages?General Data Protection Regulations (GDPR)Sarbanes–Oxley (SOX)Payment Card Industry Data Security Standard (PCI DSS)Health Insurance Portability and Accountability Act (HIPAA)
7 You are in the early stages of gathering business and technical requirements. You have noticed several references about needing up-to-date and consistent information regarding product inventory and support for SQL reporting tools. Inventory is managed on a global scale, and the warehouses storing inventory are located in North America, Africa, Europe, and Asia. Which managed database solution in Google Cloud would you include in your set of options for an inventory database?Cloud StorageBigQueryCloud SpannerMicrosoft SQL Server
8 A developer at Mountkirk Games is interested in how architects decide which database to use. The developer describes a use case that requires a document store. The developer would rather not manage database servers or have to run backups. What managed service would you suggest the developer consider?Cloud FirestoreCloud SpannerCloud StorageBigQuery
9 Members of your company's legal team are concerned about using a public cloud service because other companies, organizations, and individuals will be running their systems in the same cloud. You assure them that your company's resources will be isolated and not network-accessible to others because of what networking resource in Google Cloud?CIDR blocksDirect connectionsVirtual private cloudsCloud Pub/Sub
10 A startup has recently migrated to Google Cloud using a lift-and-shift migration. They are now considering replacing a self-managed MySQL database running in Compute Engine with a managed service. Which Google Cloud service would you recommend that they consider?Cloud DataprocCloud DataflowCloud SQLPostgreSQL
11 Which of the following requirements from a customer make you think the application should run in Compute Engine and not App Engine?Dynamically scale up or down based on workloadConnect to a databaseRun a hardened Linux distro on a virtual machineDon't lose data
12 Mountkirk Games wants to store player game data in a time-series database. Which Google Cloud managed database would you recommend?BigtableBigQueryCloud StorageCloud Dataproc
13 The original video captured during helicopter races by the Helicopter Racing League are transcoded and stored for frequent access. The original captured videos are not used for viewing but are stored in case they are needed for unanticipated reasons. The files require high durability but are not likely to be accessed more than once in a five-year period. What type of storage would you use for the original video files?BigQuery Long Term StorageBigQuery Active StorageCloud Storage Nearline classCloud Storage Archive class
