Oracle Cloud Platform Data Management 2018 Associate - 1Z1-950 Exam Practice Test

A. You can expect an outage of your MySQL Cloud Service during the planned time.

B. You need to agree to the maintenance windows. If not, you are not affected by the outage.

C. There are no maintenance operations planned. You need to do them manually.

D. Depending on the planned outage, you may not be affected by it. You need to read the maintenance details in the support notice.

A. Custom IORM plans can be created using the ALTER IORMPLAN command from SQL *Plus when connected to one of the instances.

B. If an Exadata Service has three databases, one with a share value of 2, another with a share value of 4, and the third with a share value of 1, the first database will get two I/Os out of every seven, the second database four I/Os out of every seven, and the last database one I/O out of every seven.

C. Each database is allocated a share value between 1 and 64.

D. If an Exadata Service has three databases, one with a share value of 4, another with a share value of 2, and the third with a share value of 7, and only the first database is doing I/O, it will only receive four I/Os out of every 13.

E. IORM will only intervene when I/O resources become limited.

A. Oracle Database Cloud Service

B. Oracle MySQL Cloud Service

C. Oracle Storage Cloud Service

D. Application Container Cloud

E. Oracle Java Cloud Service

F. Oracle Compute Cloud Service

A. They've specified an RSA key size that's too small to interface with the cloud.

B. The DBA has not enabled native Oracle net encryption in the cloud through the CLOUD_ENCRYPTION_SERVER and CLOUD_CRYPTO_CHECKSUM_SERVER parameters in their cloud instance sqlnet.ora file.

C. There sre no values assigned to the two sqlnet.ora parameters, CLOUD_ENCRYPTION_SERVER and/or CLOUD_CRYPTO_CHECKSUM_SERVER or they don't exist on the client.

D. They have explicitly set ENCRYPTION_CLIENT and CRYPTO_CHAECKSUM_CLIENT as
"rejected" in sqlnet.ora. This will create an unencrypted connection, which will automatically fail because it's insecure.

E. The DBA has set ENCRYPTION_SERVER and CRYPTO_CHECKSUM_SERVER to "required" in the sqlnet.ora file. This will create an unencrypted connection, which will automatically fail because it's insecure.

A. bzip ssh command

B. Windows ssh-rsa.exe command

C. Linux/UNIX ssh-keygen command

D. Putty PuTTYgen command

E. Solaris cloud-keygen command

A. Set all the tablespaces in the on-premises database to READ ONLY mode regardless of whether they will be migrated or not.

B. Set all the tablespaces in the on-premises database that you plan to migrate to READ ONLY mode.

C. Invoke Data Pump Export on the on-premises database host and specify VERSION=12.

D. If the on-premises database is not at release version 11.2.0.3 or later, you must first upgrade it to at least
11.2.0.3

E. Invoke Data Pump Import on the Database Cloud Service compute node and specify VERSION=12.

A. 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.

B. 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.

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 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.
