Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q41-Q46):

NEW QUESTION # 41
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?

  • A. -> start /System
  • B. -> start /SYS/power
  • C. -> set /SYS power_state=ON
  • D. -> start /SYSTEM/power
  • E. -> start /SP/console
  • F. You must be physically present in the data center to start an Exadata Storage Server.

Answer: B Explanation:
ILOM (Integrated Lights Out Manager) is a remote management system that allows you to control and monitor Exadata Database Machine components, such as storage servers and database servers, from a remote location. The command "start /SYS/power" is used to power on the storage server in the Exadata Database Machine after hardware maintenance. This command can be executed remotely via ILOM.
NEW QUESTION # 42
Which two statements are true about the initial storage configuration after the standard (non-virtualized) deployment of a new Exadata Database Machine with High Capacity storage servers?

  • A. There is free space available on the hard disks inside the database servers for possible extension of the /uoi file system.
  • B. The sparse<DBMNAME> diskgroup is created automatically.
  • C. There is free space available on flashdisks inside the Exadata storage servers for possible use for storage indexes.
  • D. There is free space available on flashdisks inside the Exadata storage servers to configure Exadata Smart Flash Logs.

Answer: B,E Explanation:
This is according to the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book [1]. The other statements are false as there is no free space available on the hard disks inside the database servers for possible extension of the /uoi file system, and there is no free space available on flashdisks inside the Exadata storage servers for possible use for storage indexes or to configure Exadata Smart Flash Logs [2][3].

I/O performance of the prod database on your Exadata Database Machine has degraded slightly over the past month. The database has been allocated to the OLTP I/O Resource Management (IORM) category.
Which two monitoring tools might be useful in examining I/O performance for the prod database?

  • A. OS I/O metrics using OS tools such as iostat on the database servers
  • B. I/O-specific dynamic performance views such as v$iostatfiie, v$iostatfunction, and v$iostatconsumergroup from the prod database instances using SQL *p1us
  • C. OS I/O metrics using Enterprise Manager host pages for the storage servers
  • D. OS I/O metrics using OS tools such as iostat on the storage servers
  • E. cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk

Answer: C,E Explanation:
1. OS I/O metrics using Enterprise Manager host pages for the storage servers: Enterprise Manager provides a detailed view of the storage server's performance including I/O metrics and statistics. You can use these metrics to analyze I/O performance and identify any bottlenecks.
2. cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk: These commands are used to gather information about storage server performance, including I/O statistics, disk usage, and resource allocation.
