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.)

Your company hosts an application on many compute instances in the same subnet in OCI. You have an Ansible playbook to ensure that all instances have the latest versions of dependencies installed.
Which three are required to run the playbook in OCI Cloud Shell?

When you provision a compute instance in Oracle Cloud Infrastructure (OCI), you can provide data to cloud-init on the instance. This data is referred to as "user data" by cloud-init. and can be written in various formats that cloud-init can read.
Which two file formats can be used to write user data with cloud- init?

Your team implemented a SaaS application that requires a whole system deployment for each new customer.
The infrastructure provisioning is already automated via Terraform, and now you have been asked to develop an Ansible playbook to centralize configuration file management and deployment. What is the most effective way to ensure your playbooks are utilizing up-to-date and accurate inventory? (Choose the best answer.)

You set up a bastion host in your Virtual Cloud Network (VCN) to allow only your IP ad-dress (140.19.2.140) to establish SSH connections with your compute instances that are deployed in a private subnet. The compute instances have an attached Network Security Group (NSG) with a Source Type:
Network Security Group (NSG), Source NSG: NSG-050504. To secure the bastion host, you add the following ingress rules to its NSG: Type: All TCP Proto-col: TCP Port Range: 22 Source: 140.19.2.140/32 Type: All TCP Protocol: TCP Port Range: 22 Source: NSG-050504 However, when you check the bastion host logs, you discover that there are IP addresses other than your own that can access your bastion host.
What is the root cause of this issue?
