Practice Test 4 | Google Cloud Certified Professional Cloud Architect | Dumps | Mock Test
Your company has developed a series of LAMP stack applications, that are required to be scalable and fast and that are often updated by the IT teams. Which of the following actions allow you to facilitate the process of managing the various configurations in production, staging, and development? (Select FOUR)
A. Organize Configuration and update Instance Templates
B. Create deployments using Deployment Manager
C. Use Labels for your Resources
D. Use Template Name with prefixes
E. Organize Resources according to your standard and setup/reuse configurations and templates
F. Always use expanded configuration
G. Use References, template properties, and outputs
Correct Answers – B, C, E, G
A is incorrect. Instance Templates are immutable, stored resources used for the creation of VM instances and managed instance groups only with identical configurations. So it is not possible to update an existing instance template or change an instance template after it has been created. If an instance template goes out of date, or you need to make changes to the configuration, you have to create a new instance template

B is correct. Deployment Manager allows to create resources for applications in a declarative format using YAML, Python, or Jinja2 and to deploy them in a repeatable way.
It also allows adding, deleting, or changing resources in the deployment and allows the reuse of common deployment paradigms such as a load balanced, auto-scaled instance group.

C is correct. With labels, you can group related resources together by adding metadata to your resources in the form of key-value pairs. Labels are a good way to categorize resources related to different deployments and are also useful to distinguish the current stage, for example, the production or test environment.
D is incorrect. Labels are more useful, flexible and effective compared to prefixes.
E is correct. A configuration contains the structure of your deployment, with the reference of all the resources needed, that you can define only once.
F is incorrect. It is not optimized, it may lead to errors and it is useless: you may always check your expanded configuration previewing your deployments.
G is correct. The use of template properties and outputs is advisable because it allows you to pass in variables like the zone, machine size, a number of machines, the application state (test, prod, staging) into your templates and get output values back such as the IP address and the selfLink to a VM instance.
