Oracle Cloud Infrastructure 2019 Developer Associate — Question 152

You currently manage an e-commerce application that utilizes 25 identical compute resources to handle customer traffic. The stakeholders have asked you to create another 25 identical compute resources in order to deploy and test a new version of the software?
What is the most efficient process to create 25 additional compute resources that are identical to the first 25?

Answer options

• A. Create a custom image from 1 of the 25 servers. Use this custom image to provision 25 more servers
• B. Create a manual backup of each boot volume belonging to the 25 servers. Restore each backup to create 25 new boot volumes, from which you will provision 25 more servers
• C. Provision a new server and configure it to be identical to the first 25. Create a custom image from the new server, then use the custom image to provision 24 more servers
• D. Clone the boot volume of 1 of the 25 servers. Use the boot volume clone to provision 25 more servers

Correct answer: A

Explanation

The correct answer is A because creating a custom image from one of the existing servers allows for quick and consistent provisioning of new servers that are identical to the initial ones. Option B is less efficient due to the manual backup and restore process, while option C requires additional setup time for the new server before creating the image. Option D involves cloning a boot volume, which can be more complex and less efficient compared to using a custom image.
