NO.31 Before migrating to MySQL HeatWave, what is the MOST important action to take regarding user accounts and privileges?

Reset all user passwords to default values.

Ensure all user accounts and privileges are compatible with MySQL 8.0, and recreate any incompatible accounts on the target instance.

Delete all user accounts except for the root account.

Migrate all user accounts to use external authentication (e.g., LDAP).

Merge all user accounts into a single ‘admin’ account.

NO.32 When provisioning an Exadata Database Service, which two networking components are mandatory?

A public subnet for the Exadata Infrastructure to allow external access for monitoring.

A Service Gateway to allow access to Oracle Services without traversing the public internet.

A private subnet for the client network to ensure secure database access.

A NAT Gateway for each VM within the VM Cluster to allow outbound internet access for patching.

A private subnet for database backups to Oracle Cloud Infrastructure Object Storage.

NO.33 Which of the following statements accurately describes the recommended procedure for patching Grid Infrastructure in a BaseDB VM system where the database is NOT managed by Oracle Cloud Infrastructure (OCI)?

Apply the Grid Infrastructure patch directly to the DB system. OCI handles the patching order for all components automatically.

Apply the database patch first, then apply the Grid Infrastructure patch to ensure compatibility.

Apply the Grid Infrastructure patch first, then apply the database patch, after validating the GI is working correctly.

You cannot manually patch Grid Infrastructure in a BaseDB VM system; Oracle Cloud Infrastructure manages all patching operations.

NO.34 When provisioning a new BaseDB VM, which statement BEST describes the relationship between the available Database Versions and the selected Operating System image?

All Database Versions are compatible with all Operating System images available in the OCI Marketplace.

Only Database Versions compatible with the underlying Operating System image are presented as options during provisioning.

The chosen Operating System image is automatically upgraded to the latest version compatible with the selected Database Version after provisioning.

The Database Version determines the Operating System image that will be used, irrespective of the initially selected image.

NO.35 Which aspect of NoSQL Database Cloud Service is LEAST impacted by the choice of SDK used in an application?

Syntax for querying data.

Method for authenticating with the service.

Underlying database architecture and scalability characteristics.

Error handling mechanisms.

NO.36 Within the context of Oracle Cloud Infrastructure (OCI) Base Database Service (BaseDB) virtual machine (VM) provisioning, which action is typically the RESPONSIBILITY of the customer?

Ensuring the underlying hardware infrastructure remains fault-tolerant.

Managing the Oracle Grid Infrastructure software stack.

Maintaining the OCI hypervisor software.

Automatically applying critical security patches to the operating system.

NO.37 You are managing an Exadata Database Service (ExaDB) and need to perform a full backup of the database to Oracle Cloud Infrastructure Object Storage using the bkup_api utility. The backup must include all datafiles and control files. Which bkup_api command will achieve this?

bkup_api bkup_start –dbname=dbname

bkup_api bkup_start –datafiles –controlfile –dbname=dbname

bkup_api bkup_start –full –dbname=dbname

bkup_api bkup_start –all –dbname=dbname

NO.38 Which two functionalities can be accomplished using the Performance Hub within Database Management for monitoring?

Execute ADDM (Automatic Database Diagnostic Monitor) analysis on a historical workload.

Directly modify database initialization parameters.

Identify blocking sessions that are impacting database performance.

Upgrade the database to a newer version.

NO.39 Which two actions must you undertake when configuring the networking to provide network connectivity for a MySQL HeatWave DB System instance?

Ensure the subnet used has a Service Gateway to Oracle Services, such as Object Storage, so that patching can be applied.

Deploy the MySQL HeatWave DB System to a public subnet to allow external connectivity for users.

Create ingress security rules in the VCN security list or Network Security Groups (NSGs) to allow traffic to the MySQL HeatWave DB System.

Configure a dynamic routing gateway for inter-VCN connectivity.

Create egress security rules in the VCN security list or Network Security Groups (NSGs) to block access from the MySQL HeatWave DB System to any outside network.

NO.40 If the provisioned read capacity units (RCUs) are consistently underutilized for a NoSQL Database Cloud Service table, what is the MOST direct consequence?

Improved query performance.

Increased storage efficiency.

Unnecessary cost expenditure.

Reduced data durability.

NO.41 If the Database Management Service is failing to collect performance metrics from a cloud database, which is the LEAST likely cause?

Incorrect IAM policies preventing the service from accessing the database.

The database is temporarily offline.

The Database Management Service instance is located in a different region than the database.

The database user account used by the Management Agent has been locked.

NO.42 You need to implement a backup and recovery strategy for your MySQL HeatWave Database System. What is the recommended method for backing up and restoring your HeatWave cluster?

Manually copying the data files from the HeatWave cluster’s storage.

Using the OCI Object Storage service for storing manual database dumps.

Utilizing OCI Database backups, which include both the MySQL Database System and the HeatWave cluster.

Relying solely on MySQL replication to another MySQL instance.

Using the MySQL Enterprise Backup tool directly on the HeatWave nodes.

NO.43 Which statement accurately reflects the impact of applying an Oracle-provided patch to the operating system on an Exadata Database Service instance using the Oracle Cloud Infrastructure (OCI) console?

The OCI console-initiated patch process only updates the database software, leaving the underlying OS untouched.

The OCI console-initiated patch process automatically updates both the database software and the underlying operating system on all compute and storage nodes concurrently.

The OCI console-initiated patch process updates the database software and the OS, allowing for a rolling update strategy on the database nodes, minimizing downtime. Storage nodes are updated separately.

The OCI console-initiated patch process only patches the storage servers; database nodes require manual OS patching.

NO.44 Which BaseDB lifecycle management activity is MOST directly associated with ensuring the continued availability of a database instance during a planned maintenance window?

Taking a full database backup using RMAN.

Performing an in-place upgrade of the database software.

Using Oracle Data Guard for a switchover operation.

Applying a quarterly security patch.

Resizing the block volume storage.

NO.45 In the context of MySQL HeatWave, what is the purpose of the HeatWave AutoPilot feature?

To automatically detect and prevent security vulnerabilities in the MySQL database.

To automatically scale the number of MySQL instances based on transactional workload demands.

To automate various aspects of HeatWave management, such as data placement, node sizing and resource allocation, and query scheduling.

To automatically generate reports on MySQL performance and usage.

To automatically back up and restore the MySQL database to Oracle Cloud Infrastructure Object Storage.
