Google CLOUD-DIGITAL-LEADER Online Questions & Answers

• Question 11:

  An organization is developing a new container-based application. They do not know how popular the application will be when launched and they do not want to pay for idle infrastructure resources.

  Which benefit of serverless computing will address this concern?

  A. Reduced development costs
  B. Built-in security
  C. Scalability
  D. Disaster recovery
  C. Scalability

  ---

  Serverless computing offers automatic scaling, which means it dynamically adjusts the computational resources based on the demand for the application. This benefit is crucial when the popularity of the application is uncertain. The organization only pays for the actual compute resources used, rather than maintaining and paying for idle infrastructure. Scalability is correct because serverless computing automatically scales up or down based on demand, ensuring that the organization does not incur costs for idle resources.

• Question 13:

  A customer has an application running in virtual machines. They are migrating this application to Google Cloud. They have previously had scaling issues when on-premises as VMs had to be pre-allocated. Capacity planning was repeatedly off mark-it's either too many VMs or too less. They want to match the capacity to demand while keeping the application running always. They don't have the time or budget to re-architect the systems using containers and Kubernetes at the mo- ment. What would be your recommendation?

  A. Run a load test on Compute Engine VMs. Get an estimate of usage. Then plan for a VM capacity of 25% above the load test value.
  B. Use the Managed Instance Group with Compute Engine
  C. Inform them that new-age companies are using microservices, containers, and Kubernetes for this and they can plan to rewrite the app quickly.
  D. Inform them that using a serverless option will take care of the scaling and they can move to Cloud Run or App Engine.
  B. Use the Managed Instance Group with Compute Engine

  Scalability. When your apps require additional compute resources, autoscaled MIGs can automatically grow the number of instances in the group to meet demand. If demand drops, autoscaled MIGs can automatically shrink to reduce your costs https://cloud.google.com/compute/docs/instance-groups

• Question 14:

  Compute Engine provides machine type recommendations to help you optimize the re-source utilization of your virtual machine (VM) instances. What is this capability called?

  A. App Engine
  B. None of the above
  C. Rightsizing Recommendations
  D. Recommendation Engine
  C. Rightsizing Recommendations

  ---

  Compute Engine provides machine type recommendations to help you optimize the resource utilization of your virtual machine (VM) instances. These recommendations are generated automatically based on system metrics gathered by the Cloud Monitoring service over the previous 8 days. Use these recommendations to resize your instance's machine type to use the instance's resources more efficiently. This feature is also known as rightsizing recommendations Reference link-https://cloud.google.com/compute/docs/instances/apply-machine-type-recommendations-for-instances

• Question 15:

  What makes Google Kubernetes Engine (GKE) an effective solution for developers working to resolve application errors?

  A. It reduces the time needed to iterate on various solutions.
  B. It provides intelligent recommendations to optimize application development.
  C. It removes the need for containerizing applications.
  D. It stores application code on multiple servers to facilitate collaboration across silos.
  A. It reduces the time needed to iterate on various solutions.

• Question 16:

  Your company has multiple internal applications used by your employees. You also have to give access to certain vendors and contractors. What is a good option for you to adopt?

  A. Keep the credentials separate for each application to reduce the blast radius in case of any issues.
  B. Use an external identity provider that is famous and popular like Facebook or Twitter; that way, even your vendors and contractors will have an account there.
  C. Allow all users, especially contractors and vendors, to bring their own identities, like those at gmail.com.
  D. Use an IDaaS (Identity as a Service) product that can centrally manage authenti-cation and authorization for the applications.
  D. Use an IDaaS (Identity as a Service) product that can centrally manage authenti-cation and authorization for the applications.

  ---

  Explanation Explanation/Reference:IDaaS-identity providers managed by the company give better control over security and privacy. Security/access can be set granularly, while also being centralized. You don't have to manage multiple credentials.

• Question 17:

  Firebase Hosting provides the following services-

  A. Dynamic content
  B. Static content.
  C. Microservices.
  D. All of the Above.
  D. All of the Above.

  Firebase Hosting-Firebase Hosting provides fast and secure hosting for your web app, static and dynamic content, and microservices. Firebase Hosting is production-grade web content hosting for developers. With a single command, you can quickly deploy web apps and serve both static and dynamic content to a global CDN (content delivery network). You can also pair Firebase Hosting with Cloud Functions or Cloud Run to build and host microservices on Firebase. Key capabilities of Firebase Hosting: Serve content over a secure connection:-The modern web is secure. Zero-configuration SSL is built into Firebase Hosting, so content is always delivered securely. Host static and dynamic content plus microservices:-Firebase Hosting supports all kinds of content for hosting, from your CSS and HTML files to your Express.js microservices or APIs. Deliver content fast: Each file that you upload is cached on SSDs at CDN edges around the world and served as gzip or Brotli. We auto-select the best compression method for your content. No matter where your users are, the content is delivered fast.

• Question 18:

  An organization meets their service level objective (SLO) of 99 999% ("five nines") How much downtime do their end users experience per year?

  A. 5 minutes
  B. 500 minutes
  C. 5 hours
  D. 5 days
  A. 5 minutes

• Question 19:

  An organization needs to train a machine learning model to categorize photographs. Which Google Cloud product or service should the organization use?

  A. Video Intelligence API
  B. AutoML Vision
  C. BigQuery ML
  D. Looker
  B. AutoML Vision

• Question 20:

  An organization wants to dynamically adjust its application to serve different user needs. What are the benefits of storing their data in the cloud for this use case?

  A. Data can be stored in archive for long term access
  B. Automatic data cleaning and validation
  C. Real-time data ingestion and analysis
  D. No data access management required
  C. Real-time data ingestion and analysis

  ---

  By storing their application data in the cloud the organization will be able to gather and analyze user behavior data in real-time. This will enable them to dynamically adjust their application for different user needs.
