Which two steps are true about performing an on-demand backup of database instance?

• A.You must disable the scheduled backup configuration.
• B.You must first connect to the compute node as the oracle user.
• C.You must execute bkup_api with the bkup_create option.
• D.You must execute bkup_api with the bkup_start option.
• E.You must first connect to the compute node as the ROOT user.

You get complaints from users of several applications that performance has degraded over time.
These applications run in this configuration:
There are three different databases and database instances.
Two of the poorly performing applications run in the same Pluggable Database (PDB) in an Oracle 12c multitenant Container Database (CDB) with four PDBs.
One of the poorly performing applications runs in a different PDB in the same CDB.
One of the poorly performing applications runs in an Oracle 12c non-CDB, which also hosts other applications.
You have the Oracle Resource Manager configured for the CDB, all PDBs, and the non-CDB.
Each application has a separate consumer group associated with the sessions that are running that application.
A check of wait events for the sessions belonging to these applications shows that the sessions are waiting longer and that there are more sessions from other applications in the same database instance.
You want to avoid scaling up your Database Deployment in Oracle Cloud.
Which three should you check and possibly reconfigure to avoid scaling up the Database Deployment?

• A.Check the shares allocated only to the consumer group in the non-CDB that is used by the poorly performing application.
• B.Check the shares allocated to all consumer groups in the non-CDB.
• C.Check the CDB plan only to configure the shares allocated to the PDB that contains the two poorly performing applications.
• D.Check the CDB plan to configure the shares allocated to all PDBs, including the PDB that contains the two poorly performing applications.
• E.Check the PDB plan for the PDB that is hosting the two poorly performing applications.
• F.Check the PDB plan for all the PDBs in the CDB, including the PDB that is hosting the two poorly performing applications.

Which command would you execute to perform DBaaS recovery with the latest backup?

• A.dbaascli orec -args -last
• B.dbaascli orec -args -latest
• C.dbaascli rec -args -last
• D.dbaascli rec -args -latest

A key pair is required to create a Database Deployment.
What can the key pair be used for?

• A.Communication between instances in a Database Cloud Service account is controlled by network security rules and security lists.
• B.The keys replace password use. Database Deployment use only key pairs; password authentication is not enable for SSH default connections.
• C.The keys are used to control the encryption that is used by Database Deployment: the first is for network encryption and the second is for database encryption.
• D.They key pair is used to start up, shut down, and manage EM Express availability.

You are migrating an Oracle Database 11.2.0.2 on-premise database to an Oracle Database Cloud Service (Database as a Service) that provides a pre-created Oracle Database 11.2.0.4 database.
Which two migration methods are possible?

• A.RMAN Transportable Tablespace (TTS)
• B.Data Pump Transportable Tablespace (TTS) export/import
• C.Remote Cloning
• D.Data Pump Transportable Database (TDB) export/import
