Acme Corporation has two environments: an on-premise Oracle Database environment and a new Oracle Database Cloud environment. Because of this, Acme users have to manage their user accounts and passwords in two places, on premises and in the cloud. What step should be taken to help eliminate the multiple sign-on, multiple password issue?
A. Enable federated login by establishing the Federated User Login and pointing all on-premises accounts to the federated login account.
B. When the service account is created, the service administrator can automatically connect the on-premises domain with the newly created cloud service domain by selecting the Federated Login Required check box and filling in the domain name.
C. Acme should assign an identity domain administrator and instruct him/her to duplicate the on-premises accounts to the cloud, and then send emails to the users instructing them to duplicate their passwords.
D. Acme could implement identity federation between the on-premises and cloud environments to achieve single sign on.
E. Identity federation is not possible between Oracle environments on premises and in the cloud.

質問 6：
An important client that you've recently begun working with is interested in moving some of their on-premises databases into the cloud. How do they determine the correct instance size for their initial deployment?
A. The client should consider the nature of their applications, number of users, and future load scale and select a shape that meets those requirements with a buffer for load spikes. A good starting point could be one that closely matches their on-premises hardware.
B. The client should carefully consider the nature of their applications, number of users, and run tests to try and predict their future workload size. They should then select a shape that will comfortably run their workload for the next few years because once they've selected a shape and instance size the only way to change is to delete the instance and redeploy.
C. Since they're moving on-premises databases to the cloud, they'll obviously want to utilize high memory shapes because everyone can use more memory and that's the best platform for the future.
D. You should advise your customer to select the largest shape with lots of OCPUs and a high memory count. They can run their database on the larger shape and monitor it to determine the optimum values and then downsize when they're sure they've got it right.
E. The only reason to move to the cloud is if the customer's on-premises hardware is older and running out of gas. Since the Oracle Database Cloud runs on the latest Intel chips and the fastest available memory, they can safely provision with less than 10% of their current on-premises hardware capacity and be sure that their database will run at its fastest.
正解：A
