You have been asked to set up connectivity between a client on-premises network and Oracle Cloud Infrastructure (OCI). The requirements are:
Low latency: The applications are financial and require low latency connectivity into OCI.Consistency: The application is not tolerant of performance variation.
Performance: The communications link needs to support up to 1.25 Gbps.
Encryption: The communications link needs to encrypt any data in transit between the on-premises network and OCI Virtual Cloud Network (VCN). The client wants to implement the above with as low a cost as possible, while meeting all of the requirements. What should you suggest? (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
Public Key
