Question 1 of 46

Which vaults are used for storing customer-managed encryption keys for Autonomous Database on Dedicated Infrastructure?

Oracle Database Vault, Oracle Key Vault

Oracle Audit Vault, Oracle Key Vault

Oracle Cloud Infrastructure Vault, Oracle Database Vault

Oracle Key Vault, Oracle Cloud Infrastructure Vault

Correct Answer: D

The correct vaults for storing customer-managed encryption keys for Autonomous Database on Dedicated Infrastructure are Oracle Key Vault and Oracle Cloud Infrastructure Vault. Oracle Key Vault is used for managing encryption keys, while Oracle Cloud Infrastructure Vault provides a secure and centralized key management platform.

Question 2 of 46

Which two are ways Oracle Database can optimally access data in Object Storage? (Choose two.)

Scan avoidance using partitioned external tables

Optimized data archive using partitioned external tables

Optimized data archive using hybrid partitioned tables

Scan avoidance using columnar pruning for .csv files

Correct Answer: A, C

To optimally access data in Object Storage, Oracle Database can utilize scan avoidance techniques and optimize data archiving. Scan avoidance using partitioned external tables is efficient because it reduces the data scanned by leveraging partitions. Optimized data archive using hybrid partitioned tables allows Oracle Database to manage large volumes of archived data efficiently by combining both internal and external partitions, enhancing access speed and storage efficiency.

Question 3 of 46

A Corporation is building a web application to allow its customers to schedule service requests online. There is also a need to run operational reports at times during nonpeak hours. The architecture team is debating whether such reports should be run on the online transaction processing (OLTP) database or in a separate data mart. The DBA Manager does not want to add anymore admin responsibility to the team and looking for a database option that's low to zero maintenance, but meets their strict performance requirements as well.

Which Oracle Cloud Infrastructure database service is appropriate for this scenario?

It is best to build a separate data warehouse, and move the OLTP data on a nightly basis.

Use Autonomous Transaction Processing (ATP) with "tpurgent" and "high" TNS services to separate connection types.

Use Autonomous Data Warehouse (ADW) because operational reporting is a higher priority this scenario.

The application should be deployed on a Kubernetes Cluster because it needs to be highly available.

Correct Answer: B

The Autonomous Transaction Processing (ATP) service on Oracle Cloud Infrastructure is optimized for transactional workloads and supports running complex queries and reports. It offers automated maintenance and tuning, making it a low-to-zero maintenance option, while also providing high performance. The use of 'tpurgent' and 'high' TNS services allows the separation of different connection types, which helps in meeting both transactional and reporting needs efficiently. This makes ATP the most appropriate choice for an application that requires low administrative effort and high performance for both OLTP and reporting tasks.

Question 4 of 46

Which statement is correct with respect to the required action to move Oracle Autonomous Database resources to a different compartment?

You do not require sufficient access permissions on the compartment that the resource is being moved to.

Moving an Autonomous Database instance does not include its automatic backups.

Moving the compartment of the Autonomous Database also moves the Autonomous Container Database and Autonomous Exadata Infrastructure.

Correct Answer: C

Autonomous Exadata Infrastructure instances and Autonomous Container Databases have no dependent resources that move with them. Associated (non-dependent) resources remain in their current compartments. This is accurate because dependent resources are those that need to be moved together with the parent resource, while associated resources can exist independently and do not need to be moved along with the parent resource.

Question 5 of 46

Which statement is true when the Autonomous Database has auto scaling enabled?

It scales the PGA and SGA size when needed for the workload.

Database concurrency is scaled up when needed by the workload.

It enables the database to use up to 3x OCPU/IO resources immediately when needed by the workload.

It increases the number of sessions available to the database.

Correct Answer: C

When the Autonomous Database has auto scaling enabled, it enables the database to use up to 3x OCPU/IO resources immediately when needed by the workload. This feature allows the database to automatically adjust its resources to meet the demand, ensuring optimal performance.
