You are working as a solution architect with a global automotive provider who is looking to create a multi-cloud solution. They want to run their application tier in Microsoft Azure while utilizing the Oracle DB Systems in the Oracle Cloud Infrastructure (OCI).
What is the most-fault tolerant and secure solution for this customer? (Choose the best answer.)

• A. Use an OCI Virtual Cloud Network remote peering connection to create a remote network connection between the application tier running in Microsoft Azure Virtual Network and Oracle Databases running in the OCI Virtual Cloud Network (VCN).
• B. Create a FastConnect virtual circuit with Microsoft Azure as the provider to establish a private interconnect between the application tier running in the Azure Virtual Network and the OCI VCN that contains the Oracle Databases.
• C. Create an encrypted, Virtual Private Network connection between the Microsoft Azure Virtual Network that contains the application tier and the OCI Virtual Cloud Network (VCN) that contains the Oracle Databases.
• D. Deploy the Oracle database system into a public subnet in your VCN and assign a public IP address. Connect your application tier running in Azure to the public IP address of the database system over the internet.

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

You are running a mission-critical database application in Oracle Cloud Infrastructure (OCI). You take regular backups of your DB system to OCI Object Storage. Recently, you notice a failed database backup status in the console.
What troubleshooting action can you perform to determine the cause of the backup failure?

• A. Ensure that your database host can connect to OCI Object Storage.
• B. Ensure that the database is not active and running while the backup is in progress.
• C. Ensure that the dcsagent program is not restarted in case of a stop/waiting status.
• D. Ensure the database archiving mode is set to NOARCHIVELOG.

A small business specializing in video processing wants to leverage cloud storage in order to lower its costs. They are looking to backup all video data generated, from an existing on-premises file server to Oracle Cloud Infrastructure (OCI). The requirement is to setup continuous data sync as changes are made to on- premises file server. What is the most cost effective solution for this scenario?

• A. Set up file storage service on OCI and mount the file system to an instance running on-premises. Move all the data to this on-premises instance and then sync the videos to the shared file system.
• B. Set up a Fastconnect virtual Circuit and nightly back up all videos to OCI Archive Storage.
• C. Setup an on-premises OCI Storage Gateway Cloud Sync to back up videos to OCI Object Storage Archive tier.
• D. Set up a VPN connect connection and back up all videos to Object storage standard bucket. Create a lifecycle policy to move files older than 30 days to Archive Storage.

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 a Public Load Balancer In front of the servers and add the servers to the Backend Set of the Public Load Balancer.
• 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 another Internet Gateway and configure it as route target for the private subnet.
