You are working on the migration of the web application infrastructure of your company from on-premises to Oracle Cloud Infrastructure. You need to ensure that the DNS cache entries of external clients will not direct them to the on-premises infrastructure after switching to the new infrastructure.
Which of the following options will minimize this problem?

• A.Reduce the TTL of the DNS records before the switch.
• B.DNS changes propagate fast enough that it is not necessary to take any action.
• C.Increase the TTL of the DNS records after the switch.
• D.Reduce the TTL of the DNS records after the switch.
• E.Increase the TTL of the DNS records before the switch.

A global retailer has decided to re-design its e-commerce platform to have a micro-services architecture. They would like to decouple application architecture into smaller, independent services using Oracle Cloud Infrastructure (OCI). They have decided to use both containers and servers technologies to run these application instances.
Which option should you recommend to build this new platform?

• A.Install a kubernetes cluster on OCI and use OCI event service.
• B.Use OCI Resource Manager to automate compute Instances provisioning and use OCI Streaming service.
• C.Use OCI functions, OCI object storage and OCI event service.
• D.Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.

You are working as a security consultant with a global insurance organization which is using Microsoft Azure Active Directory as an identity provider to manage user login/passwords. When a user logs in to Oracle Cloud Infrastructure (OCI) console, it should get authenticated by Azure AD.
Which set of steps are required to be configured in OCI to meet this requirement?

• A.Setup Azure AD as an Enterprise Application, configure OCI for single sign-on, map Azure AD groups to OCI groups, set up the IAM policies to govern access to Azure AD groups.
• B.Setup Azure AD as an Enterprise Application, map Azure AD users, groups and policies to OCI groups and users.
• C.Setup Azure AD as an Identity Provider, import users and groups from Azure AD to OCI, set up IAM policies to govern access to Azure AD groups.
• D.Setup Azure AD as an Identity Provider, map Azure AD groups to OCI groups, set up the IAM policies to govern access to Azure AD groups.

An E-Commerce company wants to deploy their web application for Oracle Database on Oracle Cloud Infrastructure (OCIJ DB Systems. In compliance with the business continuity program of the business, they need to provide a Recovery Point Objective (RPO) of 1 hour and a Recovery Time Objective (RTO) of 5 minutes. The web application should be highly available within the region and meet the RTO and RPO requirements in case of a region outage.
Which approach is the most suitable and cost effective configuration for this scenario?

• A.Deploy an Autonomous Transaction Processing (Serverless) database in one region and replicate it to an Autonomous Transaction Processing (Serverless) database in another region using Oracle GoldenGate.
• B.Deploy a 1 node VM Oracle database in one region. Manually Configure a Recovery Manager (RMAN) database backup schedule to take hourly database backups. Asynchronously copy the database backups to object storage in another OCI region. If the primary OCI region is unavailable, launch a new 1 node VM Database in the other OCI region and restore the production database from the backup.
• C.Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.
• D.Deploy a 2 node Virtual Machine (VM) Oracle RAC database in one region and replicate the database to a 2 node VM Oracle RAC database in another region using a manual setup and configuration of Oracle Data Guard.

You are helping a customer troubleshoot a problem. The customer has several Oracle Linux servers in a private subnet within a Virtual Cloud Network (VCN). The servers are configured to periodically communicate to the Internet to get security patches for applications Installed on them.
The servers are unable to reach the Internet. An Internet Gateway has been deployed In the public subnet in the VCN and the appropriate routes are configured in the Route Table associated with the public subnet.
Based on cost considerations, which option will fix this Issue?

• A.Create another Internet Gateway and configure it as route target for the private subnet.
• B.Implement a NAT instance In the public subnet of the VCN and configure the NAT instance as the route target for the private subnet.
• C.Create a NAT gateway in the VCN and configure the NAT gateway as the route target for the private subnet.
• D.Create a Public Load Balancer In front of the servers and add the servers to the Backend Set of the Public Load Balancer.
