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. Configure the Advanced Security Option (ASO).

B. Enable secure access to the Database Deployment compute node and database instance from remote hosts by using SSH.

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. Edit the machine's /etc/hostsfile.

E. Resolve your domain name to the IP address of the Database Deployment compute node by using the third-party domain registration vendor console.

Which three statements are true about roles and role assignment in Database as a Service (DBaaS)?

A. Service administrators can assign and remove roles only for users of the services that they manage.

B. The DBaaS Database Administrator role permits granting the DBaaS Database Administrator role to existing users.

C. Identity domain administrators can assign and remove roles for users in any identity domains.

D. The DBaaS Database Operator role permits scaling, patching, and backing up or restoring service instances.

E. DBaaS network administrators can grant access privileges to designated users.

How would you enable a port persistently to keep communication always open through that port?

A. You would require access to the Oracle Compute Cloud Service console to open the ports to a set of IP addresses.

B. You must contact your Oracle Database Cloud Service support team to update the port specifications for use.

C. All ports that are available in Oracle Database Cloud Service servers must use an SSH tunnel and cannot be enabled persistently.

D. 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.

What are two ways to enable a port on your computer node of Database Deployment for access to your Database Deployment?

A. Use your public and private key pairs to define a list of preferred ports that get enabled during your Database Deployment installation.

B. Create a tunnel for port forwarding by using SSH.

C. Configure all remote connections through port 22 that is assigned by default for SSH connections.

D. Ask Oracle Database Cloud Service to open the required ports.

E. Use the Oracle Compute Cloud Service Console to open ports to a set of IP addresses.

Which two can be increased to scale up the compute shape of a Database Deployment in Oracle Database Cloud Service?

B. Add more storage to the Database Deployment by using the Scale up button on the Oracle Database Cloud Service Overview page.

C. Add more network adaptors (NICs) to the storage network used by the Database Deployment by using the Scale Up button on the Oracle Database Cloud Service Overview page.

D. Add more network adaptors (NICs) to the public access network used by the Database Deployment by using the Scale Up button on the Oracle Database Cloud Service Overview page.

E. Add more CPUs to the Database Deployment by using the Scale Up button on the Oracle Database Cloud Service Overview page.

What are two things can you do on the My Services Dashboard page?

A. You can customize the metric icon for each valid service.

B. You can add a data center and identity domain to your Cloud account.

C. You can activate services for the current data center and identity domain.

D. You can check the overall status of your active services for the current data center and identity domain.

B. The database backup storage and the redo log storage are placed on the same storage volume.

C. The Oracle database product software storage and the database data file storage are placed on the same storage volume.

D. The database backup storage and the database product software storage are placed on different storage volumes.

E. The database data file storage and the redo log storage are placed on different storage volumes.

Which three are ways to scale a Database Deployment to solve performance degradation by resource shortage?

A. Add additional virtual network interfaces (VNICs) to the Database Deployment.

B. Increase the MEMORY_TARGET parameter value in each database instance that is running on the Database Deployment.

C. Increase the CPU_COUNT parameter value in each database instance that is running on the Database Deployment.

D. Increase the number of CPUs allocated to the Database Deployment.
