Demo Questions
Question 1
Which two situations require that your Database Deployment be scaled up?
- The Database Deployment instance is maxed out on semaphore sets.
- The database instance has reached the limit in the license_max_sessions database parameter.
- The Database Deployment is maxed out on CPU.
- The database instance is out of space in the sysaux and system tablespaces.
- The Database Deployment is maxed out on storage.
- The Database Deployment is maxed out on semaphores.
Correct answer: CE
Explanation:
Existing DBCS instances may scale up to bigger shapes in OCPU, Memory and Storage for vertical scaling. For horizontal scaling, DBCS provides RAC with the Extreme Performance option currently allowing applications to scale up to 2 nodes, each with a max of 16 OCPU shapes. Note: An Oracle CPU (OCPU) provides CPU capacity equivalent of one physical core of an Intel Xeon processor with hyper threading enabled. Each OCPU corresponds to two hardware execution threads, known as vCPUs.References: https://cloud.oracle.com/opc/database/faq Existing DBCS instances may scale up to bigger shapes in OCPU, Memory and Storage for vertical scaling.

Question 2
How would you enable a port persistently to keep communication always open through that port?
- You would require access to the Oracle Compute Cloud Service console to open the ports to a set of IP addresses.
- You must contact your Oracle Database Cloud Service support team to update the port specifications for use.
- All ports that are available in Oracle Database Cloud Service servers must use an SSH tunnel and cannot be enabled persistently.
- You can use server certificates to map a server’s identity to enable persistent connection through a port to a Database Deployment’s compute nodes.
Correct answer: D
Question 3
Which two functions can be managed by using the dbaascli tool?
- running health checks on your database
- creating users in the database instance
- restoring from the most recent backup
- creating a database instance
- applying a patch
Correct answer: CE
Explanation:
The dbaascli utility is provided on Oracle Database Cloud Service deployments to perform a variety of life-cycle and administration operations. Using the dbaascli utility, you can perform operations like:* Database recovery The orec latest subcommand restores the most recent backup and performs complete recovery. * Patching the database deployment The dbpatchm apply subcommand applies the patch. *Changing the password of the SYS user * Checking the status of the Oracle Data Guard configuration * Switchover and failover in an Oracle Data Guard configuration * Rotating the master encryption key References: https://docs.oracle.com/en/cloud/paas/database-dbaas-cloud/csdbi/dbaascli.html The dbaascli utility is provided on Oracle Database Cloud Service deployments to perform a variety of life-cycle and administration operations.
