Oracle MySQL HeatWave Implementation Associate Rel 1 1z0-915-1 Exam Dumps: Updated Questions & Answers (October 2025)

When restoring the backup of a stand-alone DB system to a new DB system, the following changes are allowed:

Use a different subnet for the new DB system(Answer B): You can select a different subnet within the same VCN or a different VCN for the new DB system, providing flexibility in network configuration.

Use a different shape for the new DB system(Answer C): You can choose a different compute shape for the new DB system, allowing you to scale the compute resources according to the requirements.

To restore a stand-alone DB system to a high-availability DB system with point-in-time recovery, the following are required:

B.Point-in-time recovery must be enabled before the point in time to which you want to restore: Point-in-time recovery (PITR) must be enabled beforehand to allow restoration to a specific point in time. C.An automatic backup taken before the selected point in time must be available: You need an automatic backup from before the desired restore point. D.A manual backup taken before the selected point in time must be available: Manual backups are also essential to ensure you can restore to the desired point in time.

To create a connection in Database Tools to use the SQL Worksheet feature, the following steps are required:

Create an OCI password(Answer A): This password is necessary for authentication when connecting to the MySQL DB system.

Create an OCI secret(Answer D): Secrets are used to store sensitive information like passwords securely. The secret will contain the database credentials.

Import an X.509 certificate into the OCI vault(Answer E): This certificate is required for secure connections to the database, ensuring encrypted communication.

To copy transactions from an on-premises MySQL instance to a DB system, you useinbound replication(Answer B).

Inbound Replication: This feature allows the MySQL DB system to receive and apply changes (transactions) from an external MySQL instance.

Replication Configuration: You need to set up replication between the on-premises MySQL instance and the MySQL DB system by configuring the master (on-premises) and the slave (DB system) appropriately.

The purpose of theocimds: trueoption in theutil.dumpInstancecommand is to:

D.It stores the exported files in OCI Object Storage: This option ensures that the exported database files are stored directly in Oracle Cloud Infrastructure Object Storage.

The statementsCALL sys.ML_TRAIN(‘ml_data.iris’, ‘class’, NULL, @model);andSELECT @model;are used to create and retrieve a machine learning model in MySQL HeatWave AutoML. The following are true:

The generated model handle is shown in the output(Answer B): After training the model, the handle (identifier) for the model is stored in the@modelvariable and can be retrieved with theSELECT @model;statement.

The statements create a classification model(Answer C): TheML_TRAINprocedure is used to create a classification model since the target column (class) indicates a classification problem.

The target column is class(Answer E): The second argument in theML_TRAINcall specifies the target column for the machine learning model, which isclassin this case.

Given the SSH command sets up port forwarding from the local port3311to the remote MySQL DB system port3306, the correct command to connect to the MySQL DB system from the client machine is:

C.mysqlsh mysql://admin@127.0.0.1:3311

This command connects to the local machine's port3311, which forwards the connection to the MySQL DB system at10.10.1.187:3306.

The following are features of MySQL AutoPilot:

Auto encoding(Answer C): MySQL AutoPilot automatically determines the best encoding for data to optimize storage and performance.

Auto provisioning(Answer D): MySQL AutoPilot can automatically provision additional resources based on workload demands, ensuring optimal performance.

AutoML(Answer E): MySQL AutoPilot includes AutoML capabilities, which automate the process of machine learning model selection, training, and deployment.

To replicate data from an on-premises MySQL server to a MySQL DB system running in Oracle Cloud Infrastructure (OCI), where the DB system is connected to a private subnet of a Virtual Cloud Network (VCN), you need to enable the DB system to communicate with the Internet securely. The correct configuration is tocreate a NAT gateway in the VCN and configure the DB system subnet to route Internet-bound traffic to the NAT gateway(Answer D).

NAT Gateway: A Network Address Translation (NAT) gateway enables instances in a private subnet to initiate outbound traffic to the Internet, but it prevents the Internet from initiating connections to those instances.

Route Table Configuration: You need to update the route table for the private subnet to direct traffic destined for the Internet to the NAT gateway.

Steps:

Create a NAT gateway in the OCI Console.

Update the route table associated with the private subnet to include a route rule that directs all Internet-bound traffic (0.0.0.0/0) to the NAT gateway.

You can determine the uptime of a DB system bychecking the DB system details in the OCI Web console(Answer B). The console provides information on the system status, including the uptime since the last start.

Steps:

Log in to the OCI Web console.

Navigate to the MySQL DB system.

View the details page of the DB system, where the uptime information is displayed.
