Exadata X9M Implementation Practice Test

Skills this practice test covers

• Describe the X9M database and storage server types, power distribution and the leaf and spine switches.

• Configure storage servers and ASM disk groups with CellCLI, ExaCLI, DCLI and ExaDCLI.
• Secure storage cells with CellWall, AIDE, secure boot and ASM or database scoped security.
• Monitor servers with Enterprise Manager Cloud Control or DBMCLI, and update cells with patchmgr.
• Replace a failed disk or flash card, and run the Cell Software Rescue Procedure.

  Oracle's professional exam on its cloud database services, including Exadata in Oracle Cloud Infrastructure.

How to prepare for 1Z0-902

1. 1

   Learn the X9M hardware first

   Know each database server type and storage server type, the leaf and spine switches, and how RoCE carries RDMA traffic. The later domains assume this picture of the rack.

2. 2

   Build configurations in OECA and OEDA

   Design a single rack with ZFS Storage in OECA, then use OEDA for a virtual deployment and for adding a database server. Both tools come up in the planning and installation domains.

3. 3

   Drill the storage command line

   Run CellCLI on one cell, then the same command on all cells with DCLI, and note when ExaCLI or ExaDCLI fits instead. Configuration and Administration has the most questions in the PlanetCert practice test.

4. 4

   Rehearse maintenance in order

   Write out the steps to shut down one storage server safely, replace a disk or flash card, apply a rolling update with patchmgr and run the Cell Software Rescue Procedure. The order and the checks matter in each.

5. 5

   Use the practice test last

   Take the 1Z0-902 practice test in Study Mode one domain at a time, then in Timed Mode. Ask Brainy AI Assistant to compare two tools whenever an answer depends on which one fits.

1Z0-902 glossary

19 terms from the exam objectives and the vendor's official material, each defined in a sentence.

AIDE

Advanced Intrusion Detection Environment: a tool that records the state of system files and reports any unexpected change.

ASM Cluster File System (ACFS)

A general-purpose file system built on ASM storage, used on Exadata for files such as external table data.

ASM Scoped Security

A storage server setting that lets only named ASM clusters reach particular storage on a cell.

Automatic Service Request (ASR)

A feature that detects certain hardware faults and opens a service request with Oracle Support automatically.

CellCLI

The command-line tool for managing one Exadata storage server (a cell), such as its disks, flash cache and settings.

CellWall

The firewall that runs on each Exadata storage server and limits which network traffic can reach it.

DBMCLI

The command-line tool for configuring and monitoring an Exadata database server.

DCLI

A tool that runs the same command on many Exadata servers at once, such as one CellCLI command on every cell.

Enterprise Manager Cloud Control

Oracle's central console for monitoring and managing Exadata systems and the databases on them.

ExaCLI

A tool for running storage server and database server commands on Exadata servers remotely, over the network.

Failure groups

Groups of disks that ASM places mirror copies across, so that losing one storage server does not lose every copy of the data.

Flash Cache

Flash memory in the storage servers that keeps often-used data for fast reads, and in write back mode for fast writes too.

Integrated Lights Out Manager (ILOM)

The service processor built into each server, used to manage and monitor its hardware even when the operating system is down.

Oracle Configuration Manager (OCM)

A tool that collects configuration details from Oracle systems and sends them to Oracle Support.

Oracle Exadata Configuration Assistant (OECA)

Oracle's planning tool for laying out an Exadata configuration, such as the servers and storage a rack will hold.

Oracle Exadata Deployment Assistant (OEDA)

Oracle's tool that captures an Exadata configuration and then runs the installation from it.

patchmgr

Oracle's update utility for Exadata storage servers and other components, able to update them one after another while the system stays up.

RDMA over Converged Ethernet (RoCE)

The Ethernet network that carries RDMA traffic between Exadata database servers and storage servers.

Remote Direct Memory Access (RDMA)

A network method that lets one server read or write another server's memory directly, which keeps storage traffic fast.
