Which two services would you access in order to enable or disable network ports for SSH access to your database cloud instance?

• A.Oracle Java Cloud Service
• B.Oracle Compute Cloud Service
• C.Oracle Storage Cloud Service
• D.Application Container Cloud
• E.Oracle Database Cloud Service

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 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.
• B.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.
• C.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.
• D.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.
• E.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.

Your customer is creating a new Database instance in the cloud. According to Oracle documentation, only one SSH public key can be associated with the instance at the time of creation.
Your customer wants to create four additional SSH keys. Identify two ways to accomplish this.

• A.According to Oracle documentation, only a single key is supported per instance. Adding more users with their own public keys is not permissible.
• B.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.
• C.Add additional keys using the 'Add New Key' menu in the Oracle Database Cloud Service console.
• D.As the opc user add additional public keys to the .ssh/authorized_keys file.
• E.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.

You plan to use the Remote Cloning method to migrate your on-premises Oracle Database 12c non-CDB database to an Oracle Database 12c database in the Cloud. Which three statements are true about using this method?

• A.You must execute the CREATE PLUGGABLE DATABASE command on the on-premises database prior to cloning the database.
• B.The on-premises database must be Oracle Database release 12.1.0.2 or higher.
• C.The database character sets of your on-premises database and the Database Cloud Service database do not need to be compatible.
• D.The on-premises database must be on a little endian platform.
• E.You must set the on-premises database to READ ONLY mode prior to cloning the database.
• F.You must convert the on-premises non-CDB database to a CDB database prior to cloning the database.

Which storage type can be directly attached to a cloud instance?

• A.block storage
• B.object storage
• C.network attached storage
• D.file system storage
• E.clustered volume storage
