1Z0-950受験前に知っておきたいQ&A

Oracle Cloud Platform Data Management 2018 Associate 認定 1Z0-950 試験問題：

問題 #1

Name three ways in which customers can receive notifications such as outages, configuration changes, database emergencies, and other information on their Database as a Service instances.

A. Browser pop-ups
B. Direct support call from an Oracle representative
C. Email
D. SMS
E. Notification tab on the dashboard

問題 #2

The DBA is attempting a cloud database connection and the connection is failing with the following Oracle net error: ORA-12660: Encryption or crypto-checksumming parameters incompatible. What is the cause of the problem?

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

問題 #3

What are security rules within the Compute Cloud Service?

A. They are user role designations that assign rights to certain users.
B. Security rules are data encryption levels that control who can see the data.
C. They allow administrators access to applications in the cloud.
D. They are firewall rules that help control traffic between Cloud Service instances as well as between instances and external hosts.

問題 #4

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

問題 #5

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 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. 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 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.
D. 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.
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.
