You have been monitoring your company's applications running in Oracle Cloud Infrastructure (OCI) and notice that the application is using OCI Traffic Management service. This service uses a traffic steering policy to distribute the DNS traffic based on subnet addresses in a rule set.
Which steering policy is in use in this particular case? (Choose the best answer.)

• A. IP Prefix steering
• B. Geolocation steering
• C. ASN steering policy
• D. Load Balancing policy

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.Standard2.1 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.
• B. Create an instance with 1 OCPU shape. Use a CLI script to clone it when more resources are needed.
• C. 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.
• D. Create an instance with 1 OCPU shape. Use the Resize Instance action to scale up to a larger shape when more resources are needed.

You have the following compartment structure within your company's Oracle Cloud Infrastructure (OCI) tenancy:

You want to create a policy in the root compartment to allow SystemAdmins to manage VCNs only in CompartmentC.
Which policy is correct? (Choose the best answer.)

• A. Allow group SystemAdmins to manage virtual-network-family in compartment Root
• B. Allow group SystemAdmins to manage virtual-network-family in compartment CompartmentB:CompartmentC
• C. Allow group SystemAdmins to manage virtual-network-family in compartment CompartmentC
• D. Allow group SystemAdmins to manage virtual-network-family in compartment CompartmentA:CompartmentB:CompartmentC

You have a 750 MIB file in an Oracle Cloud Infrastructure (OCI) Object Storage bucket. You want to download the file in multiple parts to speed up the download using the OCI CLI. You also want to configure each part size to be 128 MIB.
Which is the correct OCI CLI command for this operation? (Choose the best answer.)

• A. oci os object get -ns my-namespace -bn my-bucket --name my-large-object -- multipart-download-threshold 500 --part-size 128
• B. oci os object download -ns my-namespace -bn my-bucket --name my-large-object -- resume-put --multipart-download-threshold 500 --part-size 128
• C. oci os object get -ns my-namespace -bn my-bucket --name my-large-object -- multipart-download-threshold 750 --parallel-download-count 128
• D. oci os object download -ns my-namespace -bn my-bucket --name my-large-object -- multipart-download-threshold 750 --parallel-download-count 128

An insurance company has contracted you to help automate their application business continuity plan. They have the application running in eu-frankfurt-1 as the primary site and uk-london-1 as a disaster recovery site. Normally they have a DNS A record associated with the IP address of the primary endpoint in eu-frankfurt-1. In the event of a disaster, they use OCI DNS Zone Management to update the A record and replace it with the IP address of the endpoint in uk-londond-1.
How can you automate the failover process? (Choose the best answer.)

• A. Create a Traffic Management Steering policy with Load Balancer type and add both eu-frankfurt-1 and uk- london-1 endpoints. Attach the Traffic Management Steering policy to the A record.
• B. Create a Health Check that evaluates both regional endpoints. Create a Traffic Management Steering policy with Failover type and associate it with the Health Check.
• C. Provision a Load Balancer in Frankfurt and associate it with the A record in DNS. Create a backend set with backend servers from both eu-frankfurt-1 and uk-london-1 regions.
• D. Create a Traffic Management Steering policy and attach it to a backend servers from both eu-frankfurt-1 and uk-london-1 regions.
