You are configuring network connections for your database instance.
What does each network group represent?

• A.defines load balancing and failover configurations between RAC database instances.
• B.manages the connections between your external application servers (application servers that you currently use in your business environment) and your Oracle Database Cloud service instances.
• C.defines network connections to the Pluggable Databases (PDBs) within a Container Database.
• D.allows unrestricted communication among some of your Oracle Database Cloud service instances by using a set of defined policies and access rules.

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

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

You created a Database as a Service (DBaaS) instance. This action also created a virtual machine and configured it for the DBaaS instance. It also created two user accounts. One of the users is oracle.
What three functions can be used by Oracle users in a Database Deployment?

• A.Grant privileges and roles to database users.
• B.Create tablespaces.
• C.Reboot a VM.
• D.Back up and recover databases.
• E.Use the sudo command to perform root user access operations.
• F.Create database users.

Which three statements are true about the Oracle Cloud Service storage volumes that are created as part of a Database Deployment in Oracle Public Cloud?

• A.The Oracle database product software storage and the database data file storage are placed on the same storage volume.
• B.The database backup storage and the redo log storage are placed on the same storage volume.
• C.The database data file storage and the tempfile storage are placed on the same storage volume.
• D.The database data file storage and the redo log storage are placed on different storage volumes.
• E.The database backup storage and the database product software storage are placed on different storage volumes.

Your Database Deployment hosts a multitenant container database (CDB) with four pluggable database (PDB) tenants.
Users of an application in one PDB and users of another application in another PDB complain of poor performance.
Investigation shows that the application sessions are not using excessive CPU nor are they requesting an unusual amount of I/O.
Which two steps should you perform to resolve this problem?

• A.Examine the shares of resources allocated to each consumer group within the PDBs that contain the two applications.
• B.Add CPU to the Database Deployment.
• C.Examine the shares of resources allocated to each PDB within the CDB.
• D.Examine the shares of resources allocated to each consumer group within all four PDBs.
• E.Add memory to the Database Deployment.
• F.Add storage to the Database Deployment.
