Multiple teams are sharing a tenancy in Oracle Cloud Infrastructure (OCI). You are asked to figure out an appropriate method to manage OCI costs.
Which is NOT a valid technique to accurately attribute costs to resources used by each team? (Choose the best answer.)

• A. Create separate compartment for each team. Use the OCI cost analysis tools to filter costs by compartment.
• B. Create an Identity and Access Management (IAM) group for each team. Create an OCI budget for each group to track spending.
• C. Define and use tags for resources used by each team. Analyze usage data from the OCI Usage Report which has detailed information about resources and tags.
• D. Create a Cost-Tracking tag. Apply this tag to all resources with team information. Use the OCI cost analysis tools to filter costs by tags.

You have been asked to investigate a potential security risk on your company's Oracle Cloud Infrastructure (OCI) tenancy. You decide to start by looking through the audit logs for suspicious activity.
How can you retrieve the audit logs using the OCI Command Line Interface (CLI)? (Choose the best answer.)

• A. oci audit event list --start-time $start-time --compartment-id $compartment-id
• B. oci audit event list --end-time $end-time --compartment-id $compartment-id
• C. oci audit event list --start-time $start-time --end-time $end-time -- compartment-id $compartment-id
• D. oci audit event list --start-time $start-time --end-time $end-time --tenancy-id

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.)

• A. Create an instance pool with a VM.Standard2.2 shape instance configuration. Setup the autoscaling configuration to use 2 availability domains and have a minimum of 2 instances, to handle the weekly spikes, and a maximum of 4 instances.
• B. Create an instance with 1 OCPU shape. Use the Resize Instance action to scale up to a larger shape when more resources are needed.
• C. Create an instance with 1 OCPU shape. Use a CLI script to clone it when more resources are needed.
• D. Create an instance pool with a VM.Standard2.1 shape instance configuration. Setup the autoscaling configuration to use 2 availability domains and have a minimum of 2 instances and a maximum of 8 instances.

You are launching a Windows server in your Oracle Cloud Infrastructure (OCI) tenancy. You provided a startup script during instance initialization, but it was not executed successfully.
What is a possible reason for this error? (Choose the best answer.)

• A. Specified a #directive on the first line of your script.
• B. Ran a cloudbase-init script instead of cloud-init.
• C. Didn't include anything in user_data.
• D. Wrote a custom script which tried to install GPU drivers.

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.)

• A. Create a load balancer policy in the Traffic Management service. Configure one answer for each site. Set the answer for the primary site with a weight of 10 and the answer for the secondary site with a weight of 100.
• B. Create a new A record in DNS that points to the public load balancer at the secondary site. Create a CNAME for the sub-domain failover that will resolve to the new A record. Inform customers to prepend the website URL with failover if the primary site is unavailable.
• C. Create a failover policy in the Traffic Management service. Set the IP address of the public load balancer for the primary site in answer pool 1. Set the IP address of the public load balancer for the secondary site in answer pool 2. Define a health check to monitor both sites.
• D. Deploy a new load balancer in the primary region. Create one backend set for the primary application servers and a second backend set for the standby application servers. Create a listener for the primary backend set with a timeout of 3 minutes. Create a listener for the secondary backend set with a timeout of 10 minutes.
