The application's compute instances were not part of an autoscaling group, and manual scaling was not performed in time to meet the increased demand. The bandwidth limit of the Load Balancer was reached, preventing it from handling additional incoming traffic effectively. The Load Balancer's health check configuration was too aggressive, causing unnecessary rerouting of traffic and overloading of servers. The OCI File Storage service was incorrectly configured, leading to slow reads and writes of image data.

Recently, you notice a failed database back status in the console. • Ensure that the database is not active and running while the backup is in progress. What troubleshooting action can you perform to determine the cause of the backup failure?. Ensure that the dcsagent program is not restarted in case of a stop/waiting status. Ensure the database archiving mode is set to NOARCHIVELOG. Ensure that your database host can connect to OCI Object Storage.

A company runs a public-facing application that uses a Java-based web service via a RESTful API in their on-premises data center. Use of the API is expected to double with a new product launch. The business wants to migrate their application to Oracle Cloud Infrastructure (OCI) to meet the scale and reliability requirements. In order to achieve this, they will divert only 40% of the traffic to the new Apache Tomcat web servers running on OCI and serve the remaining 60% traffic through their on-premises infrastructure. Once the migration is complete and application works fine, they will divert all traffic to OCI. How can these requirements be met with the LEAST amount of effort?. Use OCI Traffic management service with failover steering policy and distribute the traffic between OCI and on premises infrastructure. Use OCI Traffic management service with Load Balancing steering policy and distribute the traffic between OCI and on premises infrastructure. Use an OCI load Balancer and distribute the traffic between OCI and on premises infrastructure. Use VPN connectivity between on premises Infrastructure and OCI and create routing tables to distribute the traffic between them.

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 • 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. 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.). 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. 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. 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).

(OCI) in two weeks. Their data center has been recently struck by a massive hurricane and the building has been badly damaged, although still operational. They have a 100 Mbps Internet line but the connection is intermittent due to the damages caused to the electrical grid. In this scenario, what is the most effective service to use to migrate the data to OCI given the time constraints? (Choose the best answer.). Use multiple OCI Data Transfer Appliances to transfer data to OCI. Setup an OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI. Setup a hybrid network by launching a 1Gbps FastConnect virtual circuit between your data center and OCI. Use OCI Object Storage multipart upload tool to automate the migration of your data to OCI. Setup an OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI using OCI Storage Gateway Cloud Sync tool. Upload the data to OCI using OCI Object Storage multipart upload tool.

Your company needs to migrate a business critical application from your data center to Oracle Cloud Infrastructure (OCI). The application runs on Oracle • 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. 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.). Deploy Virtual Machine RAC DB system on OCI and use the ZDM tool for the database migration. Deploy Autonomous Transaction Processing Database on OCI and use the MV2ADB tool for the database migration. Deploy Exadata Cloud Service Base rack and use Oracle Data Pump tool to migrate the data from customer on-premises to OCI.

As a part of a migration exercise for an existing on-premises application to Oracle Cloud Infrastructure (OCI), you are required to transfer a 7 TB file to OCI Object Storage. You have decided to upload it using the multipart upload functionality of Object Storage. Which two statements are true? (Choose two.). It is possible to split this file into multiple parts using rclone tool provided by Object Storage. Contiguous numbers need to be assigned for each part so that Object Storage constructs the object by ordering part numbers in ascending order. After initiating a multipart upload by making a CreateMultiPartUpload REST API Call, the upload remains active until you explicitly commit it or about it. It is possible to split this file into multiple parts using the APIs provided by Object Storage. Active multipart upload can be checked by listing all parts that have been uploaded, however it is not possible to list information for an individual object part in an active multipart upload.
