You have been asked to review a network design for Oracle Cloud Infrastructure (OCI) by a major client. The client's IT team needs to provision two Virtual Cloud Networks (VCNs) for a major application. The application uses a large number of virtual machine instances. Additionally, in the future, a VCN peering will be required to allow connectivity between the VCNs.
Which of the following are valid IP ranges to consider? (Choose the best answer.)

• A.10.0.0.0/16 and 10.0.64.0/24
• B.10.0.0.0/8 and 11.0.0.0/8
• C.10.0.0.0/30 and 192.168.0.0/30
• D.10.0.8.0/21 and 10.0.16.0/22

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 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.
• B.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.
• C.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.
• D.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.
