There are multiple options of migrating Oracle Databases from on-premises to Oracle Cloud Infrastructure.
Which two characteristics do you need to consider when choosing a migration method? (Choose two.)

• A.On-premises database version and quantity of data, including indexes
• B.On-premises database character set and application version
• C.On-premises connectivity using remote and local VCN peering
• D.On-premises host operating system platform and network bandwidth

You are deploying a highly available web application in Oracle Cloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs).
How many subnets should you create to deliver a secure highly available application?

• A.six subnets in total; two subnets in each AD; one for the load balancer and one for the web servers
• B.five subnets in total; two subnets each in the first and second AD with a single subnet in the third AD
• C.four subnets in total; one subnet in each AD for the web servers and a single subnet in any one AD for the load balancer
• D.three subnets in total; one subnet in each AD

You created a public subnet and an internet gateway in your virtual cloud network (VCN) of Oracle Cloud Infrastructure. The public subnet has an associated route table and security list.
However, after creating several compute instances In the public subnet, none can reach the Internet. Which two are possible reasons for the connectivity Issue?

• A.There Is no stateful egress rule In the security list associated with the public subnet.
• B.There is no stateful ingress rule in the security list associated with the public subnet.
• C.The route table has no default route for routing traffic to the internet gateway.
• D.There Is no dynamic routing gateway (DRG) associated with the VCN.
• E.A NAT gateway is needed to enable the communication flow to internet.

You deployed a compute instance (VM.Standard2.16) to run a SQL database. After a few weeks, you need to increase disk performance by using NVMe disks; the number of CPUs will not change. As a first step you terminate the instance and preserve the boot volume.
What is the next step?

• A.Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume and move the SQL Database data to block volume
• B.Create a new instance using a VM.Standard1.16 shape using the preserved boot volume and move the SQL Database data to NVMe disks
• C.Create a new instance using a VM.DenseIO2.8 shape using the preserved boot volume and move the SQL Database data to NVMe disks
• D.Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume move the SQL Database data to NVMe disks

You have deployed a compute instance (VM.Standard2.24) to run an Oracle database. With this set up, you run into some performance issues and want to leverage an OCI Dense IO shape (VM.DenseIO2.24), with which you get 25.6 TB local NVMe SSD. You do not want to lose the configuration changes you made to the instance. Which of the following TWO steps ARE NOT required to make this transition?

• A.Create a new instance using the VM.Dense102.24 shape using the preserved boot volume and move the Oracle Database data to NVMe disks
• B.Terminate the VM.Standard2.24 instance and preserve the boot volume
• C.Terminate the VM.Standard2.24 instance and do not preserve the boot volume
• D.Create a new instance using a VM.DenseIO2.24 shape using the preserved boot volume and move the Oracle Database data to block volumes
