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

You want all your colleagues to be able to access the compute node associated with an Oracle Database Cloud - Database Deployment. You want them to do so by using a custom host name rather than an IP address regardless of the client machine (personal or provided by the company) that they use for the access.
How would you enable this access?

• A.Enable secure access to the Database Deployment compute node and database instance from remote hosts by using SSH.
• B.Edit the machine's /etc/hosts file.
• C.Contact the administrator of your company's intranet DNS and request a custom DNS record for the compute node's public IP address.
• D.Configure the Advanced Security Option (ASO).
• E.Resolve your domain name to the IP address of the Database Deployment compute node by using the third-party domain registration vendor console.

Identify the access that is initially available to connect to your Oracle Database Cloud Service environment?

• A.Enterprise Manager on port 1158
• B.SSH on port 22
• C.telnet on port 23
• D.Cloud Control on port 7799
• E.SSL/TLS on port 443

Which two statements are true about controlling traffic among Database Deployments using a security list?

• A.Database Deployment prevents security lists from having unrestricted communication among Database Deployments.
• B.By default, the Database Deployment in a security list are accessible from hosts outside the security list.
• C.You can add a Database Deployment to a security list, thus enabling communication with all other Database Deployments both inside and outside the security list.
• D.You can add a Database Deployment to a network group, but this enables communication only within this network group.
• E.You can create a security list to enable unrestricted communication among your Database Deployments.

What is the location of the associated database files of a Database Deployment?

• A.The installer sets the database file locations during installation by configuring the data file storage options.
• B.The Database Deployment data files are stored at:/u01: Oracle product software; the entire bits Compute Cloud storage volume/u02: Oracle Database data storage; the entire data Compute Cloud storage volume/u03: Database backup storage; the entire fra Compute Cloud storage volume/u04: Database redo logs; the entire redo Compute Cloud storage volume
• C.All database instance files on the Database Deployment are stored at /u01/app/oracle/oradata.
• D.The database file locations are read from utldbfiles.ora and users can update this file to set their own locations.
