Free Oracle 1Z0-902 Exam Actual Questions
The questions for 1Z0-902 were last updated On May. 21, 2023
Which two statements are false about backup to ZFS Storage Appliance (ZFSSA)?
1. ZFS Storage Appliance (ZFSSA) can't connect directly to the Exadata 100Gb RoCE network switches. ZFSSA uses Fibre Channel protocol to connect to the Exadata storage cells. C. When backing up multi-rack systems, sharing Exadata X9M switches is not recommended. Each rack should have its own switches to minimize the risk of data loss due to switch failure.
Review the safety guidelines.
Unpack Oracle Exadata Rack.
Let the Exadata acclimatize for 24 hours.
Place Exadata in its allocated space.
Stabilize the Exadata Rack.
Power on Exadata PDU A.
Power on Exadata PDU B.
This order ensures that the necessary safety precautions are taken before installing the Exadata Database Machine, and that the machine is allowed to acclimate to its new environment before being powered on.
You are working on a remote Exadata Database Machine with current software and firmware. You now need to start a storage server after hardware maintenance.
Which ILOM command starts the storage server?
This command is based on the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and other resources. This command sets the power state of the system to ON and starts the storage server. It is the only command that is able to start the storage server remotely. All the other commands are incorrect or require the user to be physically present in the data center.
Which two options can be used to identify a damaged or failing flash card on an X9M-2 Database Machine High Capacity storage server?
The CELLCLI CALIBRATE command can be used to check the health of all flash cards in the storage server, and it should be run after logging in as the celladmin user. The hardware monitoring using the storage server ILOM should also be used to check for errors and other potential issues with the flash cards. The CELLCLI list LUN DETAIL command should not be used to identify a damaged or failing flash card, since it will not provide any information about the health of the flash card.

You have been asked to investigate why an Exadata Database Server stopped communicating on the client network for 10 minutes over the past weekend.
Which command would help investigate this?
Exachk is an Oracle-provided diagnostic tool that allows you to check various components of an Exadata Database Server, including the client network. The tool is located in the /opt/oracle.SupportTools/exachk/ directory and can be run with the command: exachk. This command can be run with the option ---from <Fridays_Date>_17:00:00 and ---to <Sundays_Date>_23:59:00 to specify a time range of interest, this way you can check the client network status between the specified time range. The tool checks the status of various components such as network interfaces, InfiniBand fabric, and storage servers. It also analyzes log files, configuration files, and system settings to detect any issues. The tool generates a report, which can be used to identify the root cause of the issue and provide recommendations for resolution.
Tfact1 is a tool to collect diagnostic information from Exadata and non-Exadata systems and it is not related to client network status.
Netcheck and GetExaWatcherResults.sh are not tools provided with the Exadata Database Server and they are not related to client network status.
You are planning the monitoring configuration for your Exadata X9M Database Machine.
Which three components are monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins?
1. The Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book (page 6-25) recommends using the Exadata-specific Enterprise Manager Plug-Ins to monitor ASM instances.
2. Additionally, the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book (page 6-25) recommends using the Exadata-specific Enterprise Manager Plug-Ins to monitor the storage server ILOM.
3. The Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book (page 6-25) also recommends using the Exadata-specific Enterprise Manager Plug-Ins to monitor Oracle clusterware on the database server.
