NEW QUESTION 4

A Multiple projects within your organization have long-term VM usage. Based on current demand, they are able to project into the future and estimate how many VM hours they will use every year. Going in for a committed use contract seems sensible. How can you configure committed use easily across all the projects?

• A. Enable committed use with discount sharing for the projects
• B. Review the usage of resources by each project on a daily basi
• C. Enable committed use for the following day based on that number, so that it gives maximum granularity without wastage.
• D. Take a report of each project's use in the last yea
• E. Enable committed use on a per- project basis based on the previous year's numbers.
• F. Share a Google Sheet and request each project team to send in their estimat
• G. Enable committed use accordingly on a per-project basis.

Answer: A

Explanation:

Enable committed use discounts are applied to the project from which you purchased it. To share the discount across multiple projects linked to your Cloud Billing account, enable committed use discount sharing from the console. When you enable committed use discount sharing, all of your current active committed use dis-counts in all the projects under the same Cloud Billing account, including those you previously purchased and new ones you purchase in the future are shared across your Cloud Billing account. Your sustained use discounts are also pooled and shared across all projects within your Cloud Billing account.

NEW QUESTION 5

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

Answer: CDE

Explanation:
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

NEW QUESTION 8

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.

Answer: C

Explanation:
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.

NEW QUESTION 9

All Google Cloud Platform services are associated with a project that is used to provide what functions?

• A. Manage Container Deployments
• B. Enable Services and APIs
• C. Manage DNS Services
• D. None of the Above

Answer: B

Explanation:
The recommended approach is to have folders corresponding to teams/departments and they manage the projects within that.
-> Sharing a single project will cause a conflict of resources, billing, concerns, etc.
-> One folder per project is unnecessary overuse of abstraction/grouping.
-> Teams and projects in a company should ideally be centrally managed in a single Organization.

NEW QUESTION 11

What conditions be true if a VM interface wants to send packets to the external IP addresses of Google APIs and services using Private Google Access?

• A. VM interface does not have an external IP address assigned.
• B. VM interface is connected to a subnet where Private Google Access is disabled
• C. Both A and B
• D. None of the Above.

Answer: A

Explanation:
A VM interface can send packets to the external IP addresses of Google APIs and services using Private Google Access if all these conditions are met:
- The VM interface is connected to a subnet where Private Google Access is enabled.
- The VPC network that contains the subnet meets the network requirements for Google APIs and services.
- The VM interface does not have an external IP address assigned.
- The source IP address of packets sent from the VM matches the VM interface's primary internal IP address or an internal IP address from an alias IP range.
A VM with an external IP address assigned to its network interface doesn't need Private Google Access to connect to Google APIs and services. However, the VPC network must meet the requirements for accessing Google APIs and services.

NEW QUESTION 12

A large travel services company has been running all their workloads on Google Cloud in the previous year. They looked at their past usage of cloud resources and see that there is a consistent use of 10,000 virtual machines throughout the year. Based on the projections for the following year they have a strong indication that they will use at least this much or more capacity within Google Cloud. What is one way in which they can take advantage of this knowledge?

• A. They can use these numbers to negotiate a better contract with another public cloud number.
• B. They can cut costs by cutting down on the number of VMs used.
• C. They can get into a committed use contract with Google Cloud to get a significant discount on the usage of VMs.
• D. They can ask for a sustained use discount.

Answer: C

Explanation:
Compute Engine lets you purchase committed use contracts in return for deeply discounted prices for VM usage. These discounts are referred to as committed use discounts. Committed use discounts are ideal for workloads with predictable resource needs. When you purchase a committed use contract, you purchase Compute Engine resources—such as vCPUs, memory, GPUs, local SSDs, and sole-tenant nodes—at a discounted price in return for committing to paying for those resources for 1 year or 3 years. The discount is up to 57% for most resources like machine types or GPUs. The discount is up to 70% for memory-optimized machine types.

NEW QUESTION 13
