You have been asked to review a network design for Oracle Cloud Infrastructure (OCI) by a major client. The client's IT team needs to provision two Virtual Cloud Networks (VCNs) for a major application. The application uses a large number of virtual machine instances. Additionally, in the future, a VCN peering will be required to allow connectivity between the VCNs.
Which of the following are valid IP ranges to consider? (Choose the best answer.)

One of your development teams has asked for your help to standardize the creation of several compute instances that must be provisioned each day of the week. You initially write several Command Line Interface (CLI) commands with all appropriate configuration parameters to achieve this task later determining this method lacks flexibility.
Which command generates a JSON-based template that Oracle Cloud Infrastructure (OCI) CLI can use to provision these instances on a regular basis? (Choose the best answer.)

You are asked to deploy a new application that has been designed to scale horizontally. The business stakeholders have asked that the application be deployed in us-phoenix-1.
Normal usage requires 2 OCPUs. You expect to have few spikes during the week, that will require up to 4 OCPUs, and a major usage uptick at the end of each month that will require 8 OCPUs.
What is the most cost-effective approach to implement a highly available and scalable solution? (Choose the best answer.)

Security Testing Policy describes when and how you may conduct certain types of security testing of Oracle Cloud Services, including vulnerability and penetration tests, as well as tests involving data scraping tools.
What does Oracle allow as part of this testing? (Choose the best answer.)

You are working with Terraform on your laptop and have been tasked with spinning up multiple compute instances in Oracle Cloud Infrastructure (OCI) for a project. In addition, you are also required to collect IP addresses of provisioned instances and write them to a file and save it in your laptop.
Which specific Terraform functionality can help accomplish this task? (Choose the best answer.)
