Question 1 of 70

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?

Configure the Advanced Security Option (ASO).

Enable secure access to the DBaaS instance VM and database instance from remote hosts by using SSH.

Contact the administrator of your company’s intranet DNS and request a custom DNS record for the compute node’s public IP address.

Edit the machine’s /etc/hosts file.

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