Free Oracle 1Z0-902 Exam Actual Questions

Note: Premium Questions for 1Z0-902 were last updated On Dec. 07, 2024 (see below)

Question #1

Which three statements are true about the Grid Infrastructure configuration after a nonvirtual deployment of a new Exadata Database Machine with a single cluster?

Reveal Solution Hide Solution
Correct Answer: A, B, D

For a non-virtual deployment of Oracle Exadata with a single cluster:

Single Client Access Name (SCAN) Listeners: By default, three SCAN listeners are configured on the RDMA over Converged Ethernet (RoCE) network. This setup allows for load balancing and high availability of incoming client connections across the cluster nodes.

Oracle Cluster Registry (OCR) Multiplexing: The OCR is typically stored in multiple locations within the disk groups to enhance reliability and fault tolerance. On Exadata, the OCR is multiplexed across the DATA and RECO disk groups for enhanced resilience.

ora.diskmon Resource: This is an essential component of Oracle Clusterware, responsible for monitoring and managing disk-related cluster resources. It is always enabled and kept online by Oracle Clusterware on Exadata systems.


Question #2

What are the two benefits of using Oracle Exadata Deployment Assistant (OEDA)?

Reveal Solution Hide Solution
Correct Answer: B, E

Oracle Exadata Deployment Assistant (OEDA) offers multiple benefits for configuring and deploying Exadata systems:

Configuration Gathering and Rack File Creation: OEDA simplifies the setup of Exadata environments by collecting system-specific configuration details. It uses this information to generate the Exadata Rack configuration file, which outlines the optimal setup for the particular environment, streamlining the deployment process and ensuring compatibility with Oracle best practices .

Lifecycle Management CLI for Exadata Systems: OEDA includes a command-line interface (CLI) that facilitates various lifecycle management tasks, specifically designed for Exadata systems. This CLI helps in automating deployment steps, adjusting configurations, and updating system parameters, tailored specifically for Exadata's hardware and software environment .


Question #3

Which statement is FALSE about the OEDA command line interface (OEDACU)?

Reveal Solution Hide Solution
Correct Answer: D

The Oracle Exadata Deployment Assistant Command Line Interface (OEDACU) supports a variety of configuration and lifecycle management tasks for Exadata systems, such as adding or removing nodes, resizing ASM disk groups, and managing Oracle Database home directories. However, it does not support lifecycle management for the Zero Data Loss Recovery Appliance (ZDLRA), as this device requires different management tools specific to its backup and recovery functions .


Question #4

Which two statements are correct about adding an additional database server to a physical Exadata X9M Database Machine using Oracle Exadata Deployment Assistant (OEDA)?

Reveal Solution Hide Solution
Correct Answer: C, D

https://docs.oracle.com/en/database/oracle/oracle-database/21/ladbi/db-on-exadata.html


Question #5

Which are two correct statements about backing up Exadata Database Machine?

Reveal Solution Hide Solution
