A large financial company has a web application hosted in their on-premises data center. They are migrating their application to Oracle Cloud Infrastructure (OCI) and require no downtime while the migration is on-going. In order to achieve this, they have decided to divert only 30% of the application works fine, they divert all traffic to OCI.
As a solution architect working with this customer, which suggestion should you provide them?

• A.Use OCI Traffic management with failover steering policy and distribute the traffic between OC1 and on premises infrastructure.
• B.Use OCI Traffic management with Load Balancing steering policy and distribute the traffic between OCI and on premises infrastructure.
• C.Use an OCI load Balancer and distribute the traffic between OCI and on premises infrastructure.
• D.Use VPN connectivity between on premises Infrastructure and OCI, and create routing tables to distribute the traffic between them.

You are working with a customer who needs to attach an Oracle Cloud Infrastructure (OCI) block volume to a VM instance with read/write access type. The customer wants to know if the number of IOPS and throughput performance differs between the following two choices:
* Option A: attach a single 1 TB block volume to the VM instance
* Option B: attach two separate 500 GB block volumes In a RAID 0 array configuration to the VM instance You can assume that the customer is using iSCSI attachment type to attach the volumes to the instance. In addition, you can assume 1 MB block size for throughput and 4 KB block size for IOPS consideration.
How should you respond to the customer?

• A.Both options provide the same number of IOPS and throughput performance.
• B.Option B provides better IOPS and throughput performance.
• C.Option B provides higher level of throughput, but lower level of IOPS performance.
• D.Option A provides better IOPS, but lower throughput performance.

You are responsible for migrating your on-premises legacy databases on 11.2.0.4 version to Autonomous Transaction Processing - Dedicated (ATP-D) in Oracle Cloud Infrastructure (OCI). As a solution architect, you need to plan your migration approach.
Which three options do you need to implement together to migrate your on-premises databases to OCI?

• A.Convert on-premises databases to PDB, upgrade to 19c, and encrypt.
• B.Use Oracle Data Guard to keep on-premises database always active during migration.
• C.Retain all legacy structures and unsupported features (e.g. legacy LOBs) in the on-premises databases for migration.
• D.Retain changes to Oracle shipped privileges, stored procedures or views in the on-premises databases.
• E.Use Oracle GoldenGate replication to keep on-premises database online during migration.
• F.Launch Autonomous Transaction Processing - Dedicated database in OCI.

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 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.
• D.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.
