You are working as a Cloud Operations Administrator for your company. They have different Oracle Cloud Infrastructure (OCI) tenancies for developmentand production workloads. Each tenancy has resources in two regions - uk-london-1 and eu-frankfurt-1. You are asked to manage all resources and to automate all the tasks using OCI Command Line Interface (CLI).
Which is the most efficient method to managemultiple environments using OCI CLI? (Choose the best answer.)

• A. Create environment variables for the sets of credentials that align to each combination of tenancy, region, and environment.
• B. Use OCI CLI profiles to create multiple sets of credentials in your config file, and reference the appropriate profile at runtime.
• C. Use different bash terminals for each environment.
• D. Run oci setup config to create new credentials for each environment every time you want to access the environment.

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.

• B. Wrote a custom script which tried to install GPU drivers.

You are asked to deploy a new application that has been designed to scale horizontally. The business stakeholders have asked that theapplication 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 with 1 OCPU shape.Use a CLI script to clone it when more resources are needed.
• B. 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.
• C. Create an instance with 1 OCPU shape. Use the Resize Instance action to scale up to a larger shape when more resources are needed.
• D. 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.

How can you accomplish this? (Choose the best answer.)

• A. Decrease the prefix length of AS for the FastConnect you want touse as PASSIVE connection.
• B. Enable BGP on the FastConnect that you want as the ACTIVE connection.
• C. Adjust one of the connections to have a higher ASN.
• D. Use AS PATH prepending with your routes.
