Your organization is defining the resource hierarchy for its new application in Google Cloud. You need separate development and production environments. The production environment will be deployed in Compute Engine in two regions. Which structure should your organization choose?

1. A. Create a single project for all environment
2. B. Use labels to segregate resources by environment.
3. C. Create a single project for all environment
4. D. Use tags to segregate resources by environment.
5. E. Create one project for the development environment and one project for the production environment.
6. F. Create two projects for the development environment and two projects for the production environment (one for each region).

Correct Answer: C
Many organizations have separate development and production environments so they can build and test new features without disturbing production traffic. In Optimizely, you can create separate projects for each environment to help with governance.
With separate development and production projects, your organization can safely build and QA experiments and Personalization campaigns in a development environment before deploying to production. This approach allows multiple stakeholders in your organization to act as gatekeepers for running new experiments in production.

An organization wants to create a new application in the cloud to replace an existing on-premises application. Which application modernization approach should the organization use?

1. A. Move the application to the cloud, and then change it.
2. B. Change their application, and then move it to the cloud.
3. C. Invent in greenfield.
4. D. Invent in brownfield.

Correct Answer: D
This approach carries over as much custom components as possible from the source system and minimizes initial reengineering efforts.

A customer of yours has an SLA with their client that a particular service will respond within 4 sec-onds. The end client has reported that it feels slower. Your engineers do a trial at the client site and notice that there seems to be a delay for many of the requests. It's your team's responsibility to iden-tify the issue quickly within the strict timeline for fixes according to the contract, and then fix it. What should you do?

1. A. Recommend a move to serverless technologies which will scale automatically on demand.
2. B. Add logging statements at multiple points in the application, build it, and deploy i
3. C. Now new requests will give us information on latency in the logs.
4. D. Check if the browsers used by the client are different from your
5. E. If they are, that's most likely the issue.Ensure that everybody uses the latest version of the browser that you are also using.
6. F. Use Cloud Trace to collect latency data and track how requests propagate and why there is a delay.

Correct Answer: D
Cloud Trace is a built-in tool in the Operations suite to identify issues like latency.
-> Such fixes are unlikely to change core issues like the service itself being architected or written
sub-optimally. Though changes like browser, networking, etc. are helpful, it would be the wrong approach to first recommend that the customer upgrade all their hardware and software.
-> Rewriting code and logging information is going to be time consuming. In general though, logging should always be included in code and it can give good insights. But tracing is way more specific and comprehensive for this requirement.
-> In certain cases, we might identify scaling as the issue. But we should first identify the core problem. So, start with tracing. We can also achieve scale in server-ful technologies.

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?

1. A. Virtual machines
2. B. Open source
3. C. Serverless computing
4. D. Containers

Correct Answer: A
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.

Your organization is developing a plan for migrating to Google Cloud.
What is a best practice when initially configuring your Google Cloud environment?

1. A. Create a project via Google Cloud Console per department in your company
2. B. Define your resource hierarchy with an organization node on top
3. C. Create projects based on tem members’ requests
4. D. Make every member of your company the project owner

Correct Answer: B
The Organization resource is the root node of the Google Cloud resource hierarchy and all resources that belong to an organization are grouped under the organization node. This provides central visibility and control over every resource that belongs to an organization.
