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 two options do you need to implement together to migrate your on premises databases to OCI?

• Use Oracle Data Guard to keep on premises database always active during migration
• Retain changes to Oracle shipped privileges, stored procedures or views In the on-premises databases.
• Use Oracle GoldenGate replication to keep on premises database online during migration.
• Convert on-premises databases to PDB, upgrade to 19c, and encrypt Migration.
• Retain all legacy structures and unsupported features (e.g. taw U>Bs) In the onuses databases for migration.

An E-commerce company which sells computers, tablets, and other electronics items has recently decided to move all of their on-premises infrastructure to Oracle Cloud Infrastructure (OCI). One of their on-premises application is running on an NGINX server and the Oracle Database is running in a 2 node Oracle Real Application Clusters (RAC) configuration. They cannot afford to have any application down time when they do the migration. What is an effective mechanism to migrate the customer application to OCI and set up regular automated backups?

• Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Import the on-premises database to OCI VM DB Systems using Oracle Data Pump and then enable automatic backups.
• Launch a compute instance for both the NGINX application server and the database server. Attach block volumes on the database server compute instance and enable backup policy to backup the block volumes.
• Launch a compute instance and run an NGINX server to host the application. Deploy Exadata Quarter Rack, enable automatic backups and import the database using Oracle Data Pump.
• Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Setup Oracle GoldenGate to synchronize data from their on-premises database to OCIVM Database. Export and Import the on-premises database to OCIVM DB Systems using Oracle Data Pump, apply the GoldenGate trail files to sync up the OCI database with the on-premises database. Enable automatic backups for the OCIVM database and then cutoverthe application from on-premises to OCI.

You are tasked with building a highly available, fault tolerant web application for your current employer. The security team is concerned about an increase in malicious web-based attacks across the internet and asked what you can do to add a higher level of security to the website. How should you architect the solution on Oracle Cloud Infrastructure (OCI) to meet all requirements defined by your organization? (Choose the best answer.)

• Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Deploy a Web Application Firewall (WAF) and configure the load balancer public IP address as the origin.
• Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Create a Geolocation steering policy in Traffic Management and add an answer pool that directs to the public IP address of the load balancer. Configure a global catch-all rule to use this answer pool.
• Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Ensure that each web application server is assigned a public IP address. Deploy a Web Application Firewall (WAF) and configure one Origin for each public IP address.
• Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Use the OCI Traffic Management service to create a load balancing policy that will resolve DNS evenly between all web servers.

You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use 'Volume Groups' feature. The Block volume and Compute instances exist in different compartments within your tenancy.Periodically, a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.What could be the cause?

• The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
• You are exceeding your volume group backup quota configured.
• You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.
• A compute instance with multiple block volumes attached cannot move when a compartment is moved.

You have to migrate your application to Oracle Cloud Infrastructure (OCI). The database is constantly being updated and needs to be online without interruptions. How can you transition the database to OCI without interrupting its use?

• It is impossible to migrate without interruption.
• Use an on-premises database with two-way synchronization to a cloud-based database and allow clients to connect to either databases.
• Use an on-premises database with one-way synchronization to a cloud-based database and allow clients to connect only to the cloud database.
• Use an on-premises database with one-way synchronization to a cloud-based database and allow clients to connect only to the on-premises database until it is synchronized.

A company is running High Performance Computing workloads on Oracle Cloud Infrastructure and are using OCI bare metal compute shape. They have decided to create a custom image of the bare metal instance's boot disk and use it to launch other instances.Which of the following is a NOT a true statement?

• Before you create a custom image of an instance, you must disconnect all iSCSI attachments and remove all iscsid node configurations from the instance.
• Editing custom Windows images is not supported due to hardware differences between shapes.
• Custom images do not include the data from any attached block volumes.
• You can create additional custom images of an instance while the instance is engaged in the image creation process.

A civil engineering company is running an online portal In which engineers can upload there constructions photos, videos, and other digital files. There is a new requirement for you to implement: the online portal must offload the digital content to an Object Storage bucket for a period of 72 hours. After the provided time limit has elapsed, the portal will hold all the digital content locally and wait for the next offload period. Which option fulfills this requirement?

• Create a pre-authenticated URL for the entire Object Storage bucket to read and list the content with an expiration of 72 hours.
• Create a pre authenticated URL lot each object that Is uploaded to the Object Storage bucket with an expiration of 72 hours.
• Create a Dynamic Group with matching rule for the portal compute Instance and grant access to the Object Storage bucket for 72 hours.
• Create a pre authenticated URL for the entire Object Storage bucket to write content with an expiration of 72 hours.

You are trying to troubleshoot the configuration of your Oracle Cloud Infrastructure (OCI) Load Balancing service. You have a backend HTTP service for which you have created a backend set in the load balancer. You have configured health checks for the backend set. Although the health checks appear good, customers sometimes experience transaction failures.Which of the following options will definitely lead to this problem?

• You are NOT using regional subnets in your Virtual Cloud Network. With Availability Domain (AD) specific subnet. the compute instances of the backend service running in the subnet have issues when the AD is down.
• You are using OCI Domain Name System. You have misconfigured the 'A' record with the wrong IP address leading to requests not getting routed correctly.
• You are using iSCI for block volume attachment to the compute instances in your backed HTTP service. TCP/IP configuration of your block volume attachment is not configured correctly, leading to issues in your backend service.
• You are running a TCP-level health check against your HTTP service. The TCP handshake can succeed and indicate that the service is up even when the HTTP service has issues.

After performing maintenance on an Oracle Linux compute instance the system is returned to a running state You attempt to connect using SSH t to do so. You decide to create an instance console connection to troubleshoot the issue.Which three tasks would enable you to connect to the console connection and begin troubleshooting?

• Use SSH to connect to the public: IP address of the compute Instance and provide the console connection OCID as the username.
• edit the Linux boot menu to enable access to console.
• Use SSH to connect to the service endpoint of the console connection service
• Reboot the compute instance using the Oracle Cloud Infrastructure (OCI) Management Console
• Upload an API signing key for console connection authentication.
• Stop the compute Instance using the Oracle cloud Infrastructure (OCI) Command Line interface (CLI).
