Question 1

You are running your warehouse using Autonomous Data Warehouse (ADW) service and you noticed that a newly configured batch job is always running in serial even through nothing else is running in the database.All your jobs are configured to run with parallelism enabled.
What could be the reason for this batch job to run in serial?

A.The parallelism of batchjob depends on the number of ADW databases involved in the query.

B.Parallelism on the database iscontrolled by the application, not the database.

C.The new batch job is connected to LOW consumer group.

D.The batch job depends on only one table and parallelism cannot be enabled on single-table queries.

E.The new batch job runs on database tables that are not enable for parallel execution.

Question 2

Which two statements about Oracle CloudInfrastructure File Storage Service are accurate? (Choose two.)

A.Customer can encrypt the communication to a mount target via export options.

B.Mount targets use Oracle-managed keys by default.

C.File systems use Oracle-managed keys by default.

D.Customer can encrypt data in their file system using their own Vault encryption key.

E.Communication with file systems in a mount target is encrypted via HTTPS.

Question 3

Which two statements are true about Database Cloud Service (DBCS)? (Choose two.)

A.Data Guard as a Service is offered among regions.

B.You have full control over backup schedule and retention.

C.You can manageOracle parameters at a global system level.

D.You cannot manage the database as sys/sysdba.

Question 4

You have just created an Autonomous Data Warehouse (ADW) and you want to connect to the ADW using SQL Developer.
What three items are needed to connect to the ADW using SQL Developer? (Choose three.)

A.the keystore password

B.a security list with an ingress rule for TCP port 1521

C.the client credentials file

D.the public IP address of the ADW server

E.the admin password

Question 5

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.Standard2.2 shape using the boot volume preserved,but no block volume attached.

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 and attach a new block volume to host your application.

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.DenseI02.8 shape using the boot volume preserved and use the NVMe devices to host your application.
