  Apigee comes in the following flavors:

  Apigee: A hosted SaaS version in which Apigee maintains the environment, allowing you to concentrate on building your services and defining the APIs to those services. Apigee hybrid: A hybrid version consisting of a runtime plane installed

  on-premises or in a cloud provider of your choice, and a management plane running in Apigee's cloud. In this model, API traffic and data are confined within your own enterprise-approved boundaries.

• Question 213:

  Which of the following statements describe the features of a preemptible VM in-stance? (Select Three Answer)

  A. Instance is alive for no more than 12 hours

  B. Can be pre-empted with a 30 minute notice

  C. Can be pre-empted with a 30 second notice

  D. Discounted Significantly

  E. Instance is alive for no more than 24 hours

  F. Can use free tier credits

  Correct Answer: CDE

  Instance is alive for no more than 24 hours, Can be pre-empted with a 30 second notice, Discounted Significantly.

  Preemptible VM is an instance that you can create and run at a lower cost than normal instances.

  However, Compute Engine might stop (pre-empt) these instances if it requires access to those resources for other tasks. Preemptible instances are excess Compute Engine capacity, so their availability varies with usage.

  Live at most 24 hours Can be pre-empted with a 30 second notification via API and are Discounted significantly

• Question 214:

  A customer in the European Union region is very clear that their data should not go outside the Eu-ropean Union. Their end users are spread all over the European U. They have to choose a storage option that serves all the users within Asia via web browsers as quickly as possible. Which storage option will work for them?

  

  A. Cloud Storage with a single region that is known to be within the European U

  B. Cloud Filestore is connected to virtual machines which are guaranteed to be within the European U

  C. Cloud Storage with the multi-region option of European U

  D. Cloud Storage with the dual-region option of European U

  Correct Answer: C

  Multi-region option will use multiple datacenters that are within the European Union. More regions will also help with lower latency since users are spread across the European U. https://cloud.google.com/storage/docs/locations#considerations

• Question 215:

  Which of the following is/are core storage options available on the Google Cloud Platform?

  A. Cloud Storage and Cloud Data Store

  B. Cloud Spanner

  C. Cloud SQL and Google Big Table

  D. All of the above

  Correct Answer: D

  Google Cloud Platform has other storage options to meet your needs for structured, unstructured, transactional and relational data. Core storage options: Cloud Storage, Cloud SQL, Cloud Spanner, Cloud Data Store and Google Big Table. Depending on your application, you might want to use one or several of these services to get the job done.

• Question 216:

  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

  Correct Answer: C

  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

• Question 217:

  In terms of Dockers and Kubernetes, which of the following statements are correct?

  A. Kubernetes uses Docker to deploy, manage, and scale containerized applications.

  B. Difference between Docker and Kubernetes relates to the role each play in con-tainerizing and running your applications

  C. Kubernetes can be used with or without Docker.

  D. All of the above.

  Correct Answer: D

  Kubernetes vs. Docker

  Often misunderstood as a choice between one or the other, Kubernetes and Docker are different yet complementary technologies for running containerized applications. Docker lets you put everything you need to run your application into a

  box that can be stored and opened when and where it is required. Once you start boxing up your applications, you need a way to manage them; and that's what Kubernetes does. Kubernetes is a Greek word meaning `captain' in English. Like

  the captain is responsible for the safe journey of the ship in the seas, Kubernetes is responsible for carrying and delivering those boxes safely to locations where they can be used.

  -Kubernetes can be used with or without Docker.

  -Docker is not an alternative to Kubernetes, so it's less of a "Kubernetes vs. Docker" question. It's about using Kubernetes with Docker to containerize your applications and run them at scale.

  -The difference between Docker and Kubernetes relates to the role each play in containerizing and running your applications.

  -Docker is an open industry standard for packaging and distributing applications in containers.

  -Kubernetes uses Docker to deploy, manage, and scale containerized applications.

• Question 218:

  Which of the following is / are true for Preemptible Instances.

  A. Preemptible Instances have no Service Level Agreement (Compute Engine SLA).

  B. Google Cloud Free Tier credits for compute engine do not apply to preemptible in-stances.

  C. Preemptible instances can't live migrate to a regular VM instance, or be set to au-tomatically restart when there is a maintenance event.

  D. All of the above.

  Correct Answer: D

  Preemptible instances function like normal instances but have the following limitations:

  -> Compute Engine might stop preemptible instances at any time due to system events. The probability that Compute Engine will stop a preemptible instance for a system event is generally low, but might vary from day to day and from zone to

  zone depending on current conditions.

  -> Compute Engine always stops preemptible instances after they run for 24 hours. Certain actions reset this 24-hour counter.

  -> Preemptible instances are finite Compute Engine resources, so they might not always be available.

  -> Preemptible instances can't live migrate to a regular VM instance, or be set to automatically restart when there is a maintenance event. -> Due to the above limitations, preemptible instances are not covered by any Service Level

  Agreement (and, for clarity, are excluded from the Compute Engine SLA).

  -> The Google Cloud Free Tier credits for Compute Engine do not apply to preemptible instances.

• Question 219:

• Question 220:

  How does a least privilege resource access model contribute to cloud security?

  A. Google is responsible for determining access to cloud resources.

  B. Employees may only access on-premises software with special permission.

  C. Only managers and other senior employees have cloud resource access.

  D. Employees only have access to the cloud resources necessary for their job.

  Correct Answer: D

  This is the definition of a least privilege model. A supporting principle that helps organizations achieve these goals is the principle of least privilege. The principle of least privilege addresses access control and states that an individual should have only the minimum access privileges necessary to perform a specific job or task and nothing more
