Google CLOUD-DIGITAL-LEADER Online Questions & Answers

• Question 271:

  An organization wants to transfer some of its data from Google Cloud Which of these statements is true?

  A. A technical support ticket must be raised with the correct department
  B. Customers have full control of their data and may transfer it at any time
  C. Outgoing data transfer must be enabled in the Google Cloud console.
  D. Customer data may not be transferred out of Google Cloud
  B. Customers have full control of their data and may transfer it at any time

• Question 272:

  Your ed-tech start-up was originally launched in a small geography. Any user sign-ups, course progress, tests taken, etc. are captured on a self-managed MySQL database. Every user generates many such transactions. Now you're taking the application globally and preparing for a much larger influx of users from all over the world. The existing MySQL server is unlikely to be able to scale. Which convenient option can be considered?

  A. Migrate to BigQuery
  B. Migrate to Cloud Spanner
  C. Migrate to Cloud SQL
  D. Migrate to Bigtable
  B. Migrate to Cloud Spanner

  ---

  Cloud Spanner is a global scale SQL database that scales extremely well. That would be the best choice.

• Question 273:

  An organization wants to build an entirely new infrastructure and applications in the cloud. Which application modernization approach should the organization use?

  A. Move the application to the cloud, and then change it.
  B. Change their application, and then move it to the cloud.
  C. Invent in greenfield.
  D. Invent in brownfield.
  C. Invent in greenfield.

  ---

  Explanation Explanation/Reference:A Greenfield approach is a brand-new implementation , where companies then add their needed configurations and customizations. This approach provides a clean slate to start from, does not carry over needless customizations and technical debt, and provides a solid foundation for business process re-engineering. A greenfield deployment is the design, installation and configuration of computer infrastructure where none existed before, for example, in a new office. In contrast, a brownfield deployment is an upgrade or addition to existing infrastructure using legacy components.

• Question 274:

  A customer of yours has an SLA with their client that a particular service will respond within 4 sec-onds. The end client has reported that it feels slower. Your engineers do a trial at the client site and notice that there seems to be a delay for many of the requests. It's your team's responsibility to iden-tify the issue quickly within the strict timeline for fixes according to the contract, and then fix it. What should you do?

  A. Recommend a move to serverless technologies which will scale automatically on demand.
  B. Add logging statements at multiple points in the application, build it, and deploy it. Now new requests will give us information on latency in the logs.
  C. Check if the browsers used by the client are different from yours. If they are, that's most likely the issue. Ensure that everybody uses the latest version of the browser that you are also using.
  D. Use Cloud Trace to collect latency data and track how requests propagate and why there is a delay.
  D. Use Cloud Trace to collect latency data and track how requests propagate and why there is a delay.

  ---

  Cloud Trace is a built-in tool in the Operations suite to identify issues like latency. -> Such fixes are unlikely to change core issues like the service itself being architected or written sub-optimally. Though changes like browser, networking, etc. are helpful, it would be the wrong approach to first recommend that the customer upgrade all their hardware and software. -> Rewriting code and logging information is going to be time consuming. In general though, logging should always be included in code and it can give good insights. But tracing is way more specific and comprehensive for this requirement.-> In certain cases, we might identify scaling as the issue. But we should first identify the core problem. So, start with tracing. We can also achieve scale in server-ful technologies. Reference link-https://cloud.google.com/trace

• Question 275:

  An organization wants to move from a strategic cloud adoption maturity level to a trans-formational one. How should the organization change the way they scale?

  A. None of these
  B. Deploy changes when problems arise.
  C. Deploy changes programmatically.
  D. Review changes manually.
  C. Deploy changes programmatically.

  ---

  Because automation is a transformational approach which ensures changes are constant and low-risk.

• Question 276:

  Your organization is defining the resource hierarchy for its new application in Google Cloud. You need separate development and production environments. The production environment will be deployed in Compute Engine in two regions. Which structure should your organization choose?

  A. Create a single project for all environments. Use labels to segregate resources by environment.
  B. Create a single project for all environments. Use tags to segregate resources by environment.
  C. Create one project for the development environment and one project for the production environment.
  D. Create two projects for the development environment and two projects for the production environment (one for each region).
  C. Create one project for the development environment and one project for the production environment.

  ---

  Explanation Explanation/Reference:Many organizations have separate development and production environments so they can build and test new features without disturbing production traffic. In Optimizely, you can create separate projects for each environment to help with governance. With separate development and production projects, your organization can safely build and QA experiments and Personalization campaigns in a development environment before deploying to production. This approach allows multiple stakeholders in your organization to act as gatekeepers for running new experiments in production.

• Question 277:

  An organization needs to rapidly scale its use of computing resources and honor its commitment to environmental sustainability.

  What should the organization do?

  A. Purchase energy-efficient servers for an existing on-premises data center.
  B. Refactor application software to use less energy
  C. Use a carbon-neutral energy provider for an existing on-premises data center
  D. Use a public cloud provider with energy-efficient data centers
  D. Use a public cloud provider with energy-efficient data centers

• Question 278:

  You are storing sensitive information in a Cloud Storage bucket. For legal reasons, you need to be able to record all requests that read any of the stored data. You want to make sure you comply with these requirements. What should you do?

  A. Scan the bucket using the Data Loss Prevention API.
  B. Enable Data Access audit logs for the Cloud Storage API.
  C. Enable the Identity Aware Proxy API on the project.
  D. Allow only a single Service Account access to read the data.
  B. Enable Data Access audit logs for the Cloud Storage API.

  ---

  Logged information Your Google Cloud projects contain only the audit logs for resources that are directly within the Cloud project. Other Google Cloud resources, such as folders, organizations, and billing accounts, contain the audit logs for the entity itself. Reference link-https://cloud.google.com/storage/docs/audit-logging

• Question 279:

  Which scenario is a good use case for machine learning?

  A. Creating customer recommendations
  B. Solving ethical dilemmas
  C. Classifying data with no prior examples
  D. Tasks that require human experience and intuition
  A. Creating customer recommendations

• Question 280:

  An organization has migrated several large databases to the cloud.

  It wants to increase the value of its data, improve cost controls and strengthen regulatory compliance.

  What should the organization do?

  A. Delete data stored for over a year.
  B. Establish an effective data governance program.
  C. Export relational data to modern NoSQL databases.
  D. Create monthly reports on data access and uses.
  B. Establish an effective data governance program.

  ---

  Explanation Explanation/Reference:An effective data governance program helps organizations manage data quality, privacy, and security, ensuring compliance with regulations and optimizing the value derived from data. This approach involves defining policies and procedures for data access, usage, and retention, which improves cost control and strengthens regulatory compliance. Establish an effective data governance program is correct because it provides a comprehensive framework for managing data, optimizing value, controlling costs, and ensuring compliance.
