• Question 194:

  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?

  A. Deploy the application on Compute Engine using preemptible instances
  B. Develop the application so it can run in an unmanaged instance group
  C. Create a reservation for the minimum number of Compute Engine instances you will use
  D. Start more instances with fewer virtual centralized processing units (vCPUs) instead of fewer instances with more vCPUs
  A. Deploy the application on Compute Engine using preemptible instances

  ---

  Preemptible VMs are cost-effective instances that can be used for short-lived and non-critical workloads. Since the rendering of individual scenes takes less than 12 hours and can be interrupted and restarted, you can leverage preemptible VMs to perform the rendering tasks. Preemptible VMs are available at a significantly lower cost compared to regular instances but can be preempted by GCP with a 30-second notice. By designing your rendering workflow to handle interruptions gracefully, such as checkpointing and resuming, you can take advantage of the cost savings provided by preemptible VMs. https://cloud.google.com/compute/docs/instances/preemptible

• Question 195:

  An organization wants to use BigQuery data analytics to understand their website performance, but wants to move only some data into the cloud. Which environment should the organization use?

  A. Private cloud
  B. On-premises
  C. Multi-cloud
  D. Hybrid cloud
  D. Hybrid cloud

  ---

  The assumption should be made that there is still a private network involved. Hybrid clouds always include a private cloud and are typically managed as one entity. Multi-clouds always include more than one public cloud service, which often perform different functions.

• Question 196:

  You're negotiating SLAs with a customer. You have communicated that there will be a 99.99% (four 9s) availability for the service you are providing. Every aspect of the service is under your con-trol. They want to modify the reliability to 99.999% (five 9s). What do you tell them? (Choose two answer)

  A. Yes, that could be possible. If yes, there will be a significantly higher charge be-cause the effort is significantly higher too.
  B. Yes, that is possible, but there will be an additional charge of 9% for the service because that is the additional effort required.
  C. Yes, that is possible. There is hardly any difference to provide another 0.009% availability.
  D. Ask them for the reasonable downtime they are willing to absorb. If it is more than 60 minutes in an entire year, explain how the current SLA meets that requirement.
  A. Yes, that could be possible. If yes, there will be a significantly higher charge be-cause the effort is significantly higher too.
  D. Ask them for the reasonable downtime they are willing to absorb. If it is more than 60 minutes in an entire year, explain how the current SLA meets that requirement.

  ---

  In many cases, customers might not know the implications of the 9s with respect to scheduled maintenance, upgrades, etc. It's possible that they are holding unnecessary expectations that significantly exceed their requirements.-> Even though 0.0009 % increase it looks like a small increment, an addition of a single 9 reduces the possible downtime by 10 times. So the effort is often much greater. Reference link-https://en.wikipedia.org/wiki/High_availability

• Question 197:

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

  ---

  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 Reference link-https://cloud.google.com/compute/docs/instances/preemptible

• Question 198:

  An organization currently stores its data on-premises and they receive different levels of traffic on their website every month. How could the organization benefit from modernizing their infrastructure with cloud technology?

  A. They can rely on the cloud provider for all website source code.
  B. Agile storage scalability.
  C. 100% service availability.
  D. They can shift from heavy operational expenditure to a capital expenditure model.
  B. Agile storage scalability.

  ---

  Explanation Explanation/Reference:Organizations can scale in the cloud by paying for what they use, when they use it.

• Question 199:

  An organization wants to migrate legacy applications currently hosted in their data center to the cloud. The current architecture dictates that each application needs its own operating system (OS) instead of sharing an OS.

  Which infrastructure solution should they choose?

  A. Virtual machines
  B. Open source
  C. Serverless computing
  D. Containers
  A. Virtual machines

  ---

  Virtual machines-you can install customized OS Containers-about applications Virtualization enables you to run multiple operating systems on the hardware of a single physical server, while containerization enables you to deploy multiple applications using the same operating system on a single virtual machine or server. Serverless computing would be no OS required and the open source operating system allows the use of code that is freely distributed and available to anyone and for commercial purposes such as Linux and Free BSD.

• Question 200:

  If you increase the size of a subnet in a custom VPC network, the IP addresses of virtual machines already on that subnet might be affected. Which options are Correct.

  A. False
  B. None of the above
  C. True
  D. Not Defined by Google Cloud Platform
  A. False

  ---

  Explanation Explanation/Reference:You can dynamically increase the size of a subnet in a custom network by expanding the range of IP addresses allocated to it. Doing that doesn't affect already configured VMs.
