You want all your colleagues to be able to access the compute node associated with an Oracle Database Cloud Database as a Service (DBaaS) instance. 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?

Correct Answer: C 🗳️
You can associate a custom host name or domain name to the public IP address of a compute node associated with your Oracle Database Cloud Service environment.
To associate a custom host name to the public IP address of a compute node, contact the administrator of your DNS (Domain Name Service) and request a custom DNS record for the compute nodes public IP address. For example, if your domain is example.com and you wanted to use clouddb1 as the custom host name for a compute node, you would request a DNS record that associates clouddb1.example.com to your compute node's public IP address.

With Oracle Database Cloud Service as the subscription type, you must configure a database for Backup and Recovery.
Which two options do you have to back up your database instance?

Correct Answer: AC 🗳️
When creating a new database deployment on Oracle Database Cloud Service, you choose whether you want automatic backups to be configured for the database. Your choices are:
Both Cloud Storage and Local Storage30 days' worth of backups are kept, with the 7 most recent days' worth available directly on the compute nodes local storage.
Cloud Storage Only30 days' worth of backups are kept, with all backups on cloud storage.
Noneautomatic backups are not configured.

Which users are created and can be used for database and host management of your DBaaS database servers?

Correct Answer: D 🗳️
Linux user accounts that are provisioned on an Oracle Database Cloud Service deployment that hosts an Oracle Real Application Clusters (Oracle RAC) database:
* opc
The system administrator account you use to connect to the compute node using SSH. This user can use the sudo command to perform operations that require root-user access.
* oracle
The Oracle Database administrator account you use to access the system and perform non-root database administration tasks.
* grid
The Oracle Grid Infrastructure administrator account you use to perform ASM, ACFS, and clusterware administration tasks.
* root
The root administrator for the system. You do not have direct access to this account. To perform operations that require root-user access, use the sudo command as the opc user.
