After creating an instance from an Oracle-provided Oracle Linux image, which two tasks would you perform to
ensure continued SSH access to your instance?A. Keep the SSH private key corresponding to the SSH public key specified during instance creation, to use in
case the instance is deleted and re-created.
B.
Create at least one additional user with root access on your instance and generate separate SSH keys for
this user.
C.
Promptly dispose of the SSH private key corresponding to the SSH public key specified during instance
creation.
D.
Disable the SSH key used by the Oracle Public Cloud user to ensure other users can’t use the same key.
E.
Change the SSH public key in the authorized_keys file of the Oracle Public Cloud user the first time you
log in.

When you create instances of Oracle Java Cloud Service or Oracle Database Cloud Service, a user named opc is created automatically on the underlying Oracle Compute Cloud Service VMs. You can ssh to these VMs, as opc, by using the private SSH key corresponding to the public key that was specified while creating the instances. At times, you may want to create additional SSH-enabled users on the Oracle Compute Cloud Service VMs.

We can create a ssh user with different key pairs with root access
create and assign different ssh keys for each user
and then safely disable public key.
Don`t do it! 🙂
