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 have designed and deployed your Autonomous Data Warehouse (ADW) such that it is accessible from your on-premises data center and servers running on both private and public networks in Oracle Cloud Infrastructure (OCI).

As you are testing the connectivity to your ADW database from the different access paths, you notice that the server running on the private network is unable to connect to ADW. Which two steps do you need to take to enable connectivity from the server on the private network to ADW? (Choose two.)

A. Add an entry in the Security List of the ADW allowing ingress traffic for C10R block 10.2.2.0/24

B. Add an entry in the route table (associated with the private subnet) with destination of 0.0.0.0/: target type of NAT Gateway, add a stateful egress rule to the security list (associated with the private subnet) with destination of 0.0.0.0./0 and for all IP protocols.

C. Add an entry in the access table list of ASW for CIDR block 10.2.2.0/24.

D. Add an entry in the route table (associated with the private subnet) with destination of 0.0.0.0./0; target type of internet Gateway, add a stateful egress in the security list (associated with the private subnet) with destination of 0.0.0.0/0 and for all IP protocols.

E. Add an entry in the access control list of ADW for IP address 129.146.160.11

You are working for a Travel company and your travel portal application is a collection of microservices that run on Oracle Cloud Infrastructure Container Engine for Kubernetes. As per the recent security overview, you have noticed that Oracle has published a newer image of the Operating System used by the worker nodes. You want to make sure that your application doesn't face any downtime but at the same time the worker nodes gets upgraded to the latest version of the Operating System.
What should you do to get this upgrade done without application downtime? (Choose the best answer.)

A. 1. Shutdown the worker nodes 2. Create a new node pool 3. Manually schedule the pods on the newly built node pool

B. 1. Create a new node pool using the latest available Operating System image. 2. Run kubectl cordon <node name> against all the worker nodes in the old pool to stop any new application pods to get scheduled 3. Run kubectl drain <node name> """"delete""local""data """"force """"ignore""daemonsets to evict any Pods that are running 4. Delete the old node pool

C. 1. Create a new node pool using the latest available Operating System image 2. Run kubectl taint nodes """"all node""role.kubernetes.io/master"" 3. Delete the old node pool

D. 1. Run kubectl cordon <node name> against all the worker nodes in the old pool to stop any new application pods to get scheduled 2. Run kubectl drain <node name> """"delete""local""data """"force """"ignore""daemonsets to evict any Pods that are running 3. Download the patches for the new Operating System image 4. Patch the worker nodes to the latest Operating System image

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. 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.

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. 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).
