 To perform actions on a NoSQL table, such as creating, updating, deleting, or querying rows, you need to have the appropriate permissions granted by an IAM policy. The permissions are defined by the combination of the verb and the resource type. For example, the NOSQL_TABLE_WRITE permission allows you to create or update a table, and the NOSQL_ROWS_INSERT permission allows you to insert rows into a table1.

The other options are not correct permissions to perform actions on a NoSQL table. The NOSQL_ROWS_READ and NOSQL_ROWS_DELETE permissions only allow you to read or delete rows from a table, but not to insert or update them1. The NOSQL_TABLE_INSPECT and NOSQL_TABLE_UPDATE permissions only allow you to list or modify the properties of a table, but not to create or delete it1. The NOSQL_TABLE_DESTROY and NOSQL_TABLE_ALTER permissions only allow you to drop or alter a table, but not to create or update it1. References:

Regarding MySQL Database Service HeatWave, the following two statements are true:

• HeatWave uses machine learning to automate operations, increase DBA productivity, and reduce costs. HeatWave has several features that leverage machine learning to optimize the performance and efficiency of the service, such as12:
• HeatWave is an in-memory, query-processing engine designed for fast execution of analytic queries. HeatWave is a massively parallel, distributed system that runs analytic queries in memory, using columnar data formats, vectorized execution, and adaptive algorithms. HeatWave can accelerate MySQL performance by orders of magnitude for analytics workloads, mixed workloads, and machine learning.

B is incorrect, because HeatWave does not use periodic long-running ETL batch jobs to refresh data, but a novel technique called dual-format storage. HeatWave stores data in both row and column formats, and synchronizes the data between the two formats in real time. This eliminates the need for ETL processes and enables fast execution of both transactional and analytic queries on the same data.

D is incorrect, because the HeatWave data that is needed for analytic processing is not stored in disk files, but in memory. HeatWave uses sparse files to store the columnar data in memory, which are compressed and encrypted. HeatWave also supports querying data in object storage, such as Oracle Cloud Infrastructure Object Storage or Amazon S3, using the HeatWave Lakehouse feature.

The three strategies to migrate Oracle Database to Oracle Cloud Infrastructure (OCI) are:

• Zero Downtime Migration: This is a tool that provides a simplified and automated migration experience, providing zero to negligible downtime for the production system. It supports migrating Oracle Database versions 11.2.0.4 and later, running on any platform, to any OCI Database service, including Exadata, Cloud@Customer, and Autonomous1.
• Migration Workbench: This is a feature of Oracle Enterprise Manager that provides a user interface to perform database migrations using various methods, such as Data Pump, Transportable Tablespaces, or Cross-Platform Transportable PDBs. It supports migrating Oracle Database versions 11.2.0.4 and later, running on any platform, to any OCI Database service, including Exadata, Cloud@Customer, and Autonomous2.
• GoldenGate: This is a software product that enables data replication and integration across heterogeneous databases and platforms. It supports migrating Oracle Database versions 10.2 and later, running on any platform, to any OCI Database service, including Exadata, Cloud@Customer, and Autonomous. It also supports bi-directional replication and zero downtime upgrades3.

B is incorrect, because autonomous migration is not a strategy to migrate Oracle Database to OCI, but a feature of Oracle Autonomous Database that allows you to migrate data from other sources, such as Oracle Database, MySQL, MongoDB, or Amazon S3, to an Autonomous Database instance using Oracle Data Pump or SQL Developer Web4.

C is incorrect, because Real Application Clusters (RAC) is not a strategy to migrate Oracle Database to OCI, but a feature of Oracle Database that provides high availability and scalability by enabling multiple instances to access the same database across a cluster of servers5.
