質問 4：
A customer is deploying services on the Oracle Database cloud and they want to use Enterprise Manager Database Control and Enterprise Manager Database Express. Enterprise Manager Database Control uses port 1158 and Enterprise Manager Database Express uses port 5500 which are both blocked by their internal firewall. Their network department is not allowing these ports to be opened. What can the customer do to enable access to these applications through their network firewall?
A. Use the Enterprise Manager Database Control interface to change the standard port from 1158 to one that can be supported by the customer's firewall. Use Enterprise Manager Database Express to change its port from 5500 to one that can be supported as well.
B. The customer can sign into the Oracle Compute cloud and create a security list. The security list can create a port forward for inbound and outbound traffic through the cloud.
C. Use a supported SSH client to create tunnels for the restricted ports over non-restricted ports.
D. The customer will need to wait for their network group to make a decision and open the ports for them. There isn't any other way to access these applications securely in the cloud.
E. Create a custom security rule in the Oracle Compute Service to redirect the ports of both Enterprise Manager Database Control and Enterprise Manager Database Express to port 80, which is always allowed.
正解：C

A. Add additional keys using the 'Add New Key' menu in the Oracle Database Cloud Service console.
B. As the opc user add additional public keys to the .ssh/authorized_keys file.
C. Log in to the database virtual machine as the root user, use ssh-keygen to generate four new keys, and assign them to each user in their home directory.
D. According to Oracle documentation, only a single key is supported per instance. Adding more users with their own public keys is not permissible.
E. From the Compute Cloud > Network tab, access the security rules and enable the ssh_multiple_access rule. Then you will be able to assign multiple keys to an instance through the Compute Cloud admin utility.
