Question #6
Your organization runs a distributed application in the Compute Engine virtual machines. Your organization needs redundancy, but it also needs extremely fast communication (less than 10 milliseconds) between the parts of the application in different virtual machines.
Where should your organization locate this virtual machines?
  1. A
    In a single zone within a single region
  2. B
    In different zones within a single region
  3. C
    In multiple regions, using one zone per region
  4. D
    In multiple regions, using multiple zones per region

Correct Answer:
D

Choosing option B, placing VMs in different zones within a single region, best combines redundancy with the requirement for low latency, typically under 10 milliseconds between VMs. This setup avoids the potential latency issues that may arise with inter-regional communication in option D, which although it offers increased redundancy, may not consistently deliver the sub-10-millisecond communication required for some distributed applications.

Question #7
An organization decides to migrate their on-premises environment to the cloud. They need to determine which resource components still need to be assigned ownership.
Which two functions does a public cloud provider own? (Choose two.)
  1. A
    Hardware maintenance
  2. B
    Infrastructure architecture
  3. C
    Infrastructure deployment automation
  4. D
    Hardware capacity management
  5. E
    Fixing application security issues

Correct Answer:
AD

Absolutely right! When it comes to public cloud services, the provider takes charge of both hardware maintenance and capacity management. Essentially, they ensure that physical servers and other hardware resources are not only up and running but also adequately scaled to meet user demands. So, there's no need for clients to worry about the nuts and bolts of hardware—they can focus on building and securing their apps!

Question #8
You are a program manager within a Software as a Service (SaaS) company that offers rendering software for animation studios. Your team needs the ability to allow scenes to be scheduled at will and to be interrupted at any time to restart later. Any individual scene rendering takes less than 12 hours to complete, and there is no service-level agreement (SLA) for the completion time for all scenes. Results will be stored in a global Cloud Storage bucket. The compute resources are not bound to any single geographical location. This software needs to run on Google Cloud in a cost-optimized way.
What should you do?
  1. A
    Deploy the application on Compute Engine using preemptible instances
  2. B
    Develop the application so it can run in an unmanaged instance group
  3. C
    Create a reservation for the minimum number of Compute Engine instances you will use
  4. D
    Start more instances with fewer virtual centralized processing units (vCPUs) instead of fewer instances with more vCPUs

Correct Answer:
A
chatbot-img GPT-4o - Answer
For your SaaS company's animation rendering needs, preemptible VMs on Google Cloud present a highly cost-effective solution. These VMs offer a substantial discount compared to standard instances and are especially suitable for tasks like rendering, which can tolerate interruptions. Since each scene takes less than 12 hours and the process can be paused and resumed, using preemptible VMs allows you to manage compute costs effectively while adapting the workflow to automatically save progress and restart as needed. This setup ensures efficient use of resources and aligns perfectly with the absence of strict SLA requirements for scene completion.

Question #9
Your manager wants to restrict communication of all virtual machines with internet access; with resources in another network; or with a resource outside Compute
Engine. It is expected that different teams will create new folders and projects in the near future.
How would you restrict all virtual machines from having an external IP address?
  1. A
    Define an organization policy at the root organization node to restrict virtual machine instances from having an external IP address
  2. B
    Define an organization policy on all existing folders to define a constraint to restrict virtual machine instances from having an external IP address
  3. C
    Define an organization policy on all existing projects to restrict virtual machine instances from having an external IP address
  4. D
    Communicate with the different teams and agree that each time a virtual machine is created, it must be configured without an external IP address

Correct Answer:
A

Question #10
Your multinational organization has servers running mission-critical workloads on its premises around the world. You want to be able to manage these workloads consistently and centrally, and you want to stop managing infrastructure.
What should your organization do?
  1. A
    Migrate the workloads to a public cloud
  2. B
    Migrate the workloads to a central office building
  3. C
    Migrate the workloads to multiple local co-location facilities
  4. D
    Migrate the workloads to multiple local private clouds

Correct Answer:
A
chatbot-img GPT-4o - Answer
Choosing to migrate the workloads to a public cloud perfectly addresses the goals of managing the workloads centrally and consistently while eliminating the need to manage physical infrastructure. This shift not only streamlines management practices across various geographies but also enhances operational efficiency by leveraging cloud technologies. This option is most in line with the desire to decrease direct oversight over hardware and physical systems.
