A hospital in Austin has hosted its web based medical records portal entirely In Oracle cloud Infrastructure (OCI) using Compute Instances for its web-tier and DB system database for its data tier. To validate compliance with Health Insurance Portability and Accountability (HIPAA), the security professional to check their systems it was found that there are a lot of unauthorized coming requests coming from a set of IP addresses originating from a country in Southeast Asia.
Which option can mitigate this type of attack?

• A.Block the attacking IP address by creating by Network Security Group rule to deny access to the compute Instance where the web server Is running
• B.Block the attacking IP address by implementing a OCI Web Application Firewall policy using Access Control Rules
• C.Mitigate the attack by changing the Route fable to redirect the unauthorized traffic to a dummy Compute instance
• D.Block the attacking IP address by creating a Security List rule to deny access to the subnet where the web server Is running

Which of the following options will minimize this problem?

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

Your company needs to migrate a business critical application from your data center to Oracle Cloud Infrastructure (OCI). The application runs on Oracle Database and both the application and database servers run on Oracle Linux version 7. The application server is WebLogic server running on multiple 4-core servers and the database is deployed as an Oracle Database Enterprise Edition RAC database on 2 servers (4-cores each).
Which method of database migration should you choose so that the application has minimal impact? (Choose the best answer.)

• A.Deploy Virtual Machine RAC DB system on OCI and use the Oracle Database Backup module with RMAN to migrate the data from customer on-premises to OCI.
• B.Deploy Virtual Machine RAC DB system on OCI and use the ZDM tool for the database migration.
• C.Deploy Autonomous Transaction Processing Database on OCI and use the MV2ADB tool for the database migration.
• D.Deploy Exadata Cloud Service Base rack and use Oracle Data Pump tool to migrate the data from customer on-premises to OCI.

You are responsible for a web application deployed on a set of compute VM instances in Oracle Cloud Infrastructure (OCI). Your application stores data on block volumes.
In production, the business requirement is a Recovery Point Objective (RPO) of two hours and that data should be recoverable in case of a regional failure.
How would you meet the RPO requirement in the event of a failure?

• A.Configure your application to use synchronous primary-secondary data replication between ADs.
• B.Set up cross-region volume replication to replicate the block volumes to a different OCI region.
• C.Create a user-defined storage backup policy and attach a schedule of type "Hourly" and automatically copy to another region. Apply this policy to a volume group containing the block volumes.
• D.Store hourly block volume backups to an NVMe device attached to a compute instance in a different Availability Domain (AD).
