You have been contracted by a local e-commerce company to assist with enhancing their online shopping application. The application is currently deployed in a single Oracle Cloud Infrastructure (OCI) region. The application utilizes a public load balancer, application servers in a private subnet, and a database in a separate, private subnet. The company would like to deploy another set of similar infrastructure in a different OCI region that will act as standby site. In the event of a failure at the primary site, all customers should be routed to the failover site automatically. After deploying the additional infrastructure within the second region, how should you configure automated failover requirements? (Choose the best answer.)

Scenario: 2 (Oracle Cloud-init and AutoScaling: Use cloud-init to Configure Apache on Instances in an Autoscaling Instance Pool) Scenario Description: (Hands-On Performance Exam Certification) You're deploying an Apache-based web application on OCI that requires horizontal autoscaling.
To configure instances upon provisioning, write a cloud-init script for Oracle Linux 8 that installs and enables Apache (httpd), and opens the firewall for HTTP on TCP port 80. Create aninstance configuration and include the cloud-init script in it. Use this instance configuration to create an instance pool and autoscaling configuration.
Pre-Configuration:
To fulfill this requirement, you are provided with the following:
Access to an OCI tenancy, an assigned compartment, and OCI credentials
A VCN Cloud-Init Challenge VCN with an Internet gateway and a public subnet. The security list for the subnet allows ingress via TCP ports 22 and 80 (SSH and HTTP). The route table forwards all egress to the Internet gateway.
Access to the OCI Console
Required IAM policies
An SSH key pair for the compute instance

Your deployment platform within Oracle Cloud Infrastructure (OCI) leverages a compute instance with multiple block volumes attached. There are multiple teams that use the same compute instance and have access to these block volumes. You want to ensure that noone accidentally deletes any of these block volumes. You have started to construct the following IAM policy but need to determine which permissions should be used.
allow group DeploymentUsers to manage volume-family where ANY { request.permission != <???>, request.permission != <???>, request.permission != <???> } Which permissions can you use in place of <???> in this policy? (Choose the best answer.)

You set up a bastion host in your VCN to only allow your IP address (140.19.2.140) to establish SSH connections to your Compute Instances that are deployed in a private subnet. The Compute Instances have an attached Network Security Group with a Source Type: Network Security Group (NSG), Source NSG:
NSG-050504. To secure the bastion host, you added the following ingress rules to its Network Security Group:
However, after checking the bastion host logs, you discovered that there are IP addresses other than your own that can access your bastion host. What is the root cause of this issue? (Choose the best answer.)
