You provisioned an Oracle Autonomous Data Warehouse (ADW)on Oracle Cloud Infrastructure (OCI) and imported data into ADW.
You want to give your business analyst the ability to connect to the ADW database and run queries.
Which two actions can help you meet this requirement? (Choose two.)

• A.Create a database user account for the business analyst.
• B.Grant the predefined database role DWROLE to the database user.
• C.Grant unlimited tablespace privilege to the database user.
• D.Grant the predefined database role DWADW to the database user.
• E.Grant the predefineddatabase role DWUSER to the database user.

You have an application running on Oracle Cloud Infrastructure. You Identified that the read and write operations are slowing your application downenough to impair user access. The application is currently using a VM.Standard2.1 compute without any block storage attached to it.
Which two options allow you to increase disk IOPS performance?

• A.Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.DenseI02.8 shape using the boot volume preserved and use the NVMe devices to host your application.
• B.Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.Standard2.2 shape using the boot volume preserved,but no block volume attached.
• C.Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved, but no block volume attached.
• D.Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.Standard2.2 shape using the boot volume preserved and attach a new block volume to host your application.

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