Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q26-Q31):

NEW QUESTION # 26
Which three statements are true about the CELLCLI command?

  • A. It can execute commands on multiple storage servers in parallel.
  • B. It can be executed using the DCLI utility.
  • C. It requires root privileges to create CELLDISKS and GRIDDISKS.
  • D. It can be executed on storage servers.
  • E. It has command-line history.

Answer: A,B,E

Explanation:
The CELLCLI utility is a command line interface to Exadata that enables the execution of commands across multiple storage servers in parallel. It also has command-line history, so users can easily recall previously entered commands. Furthermore, the CELLCLI utility can be executed using the DCLI utility, which provides a convenient way to execute commands on multiple storage servers simultaneously.
However, CELLCLI does not require root privileges to create CELLDISKS and GRIDDISKS, and it cannot be executed on storage servers. This is because CELLCLI is used to manage the Exadata database machine from the database server [1]. For more information about CELLCLI, refer to the Oracle Exadata Database Machine X9M Implementation Essentials official text book and resources [1][2].

NEW QUESTION # 28
Which three of the following options are available for database consolidation on Exadata?

  • A. Multiple pluggable databases in one or more container databases on a Virtual Machine or Bare Metal cluster
  • B. Multiple Virtual Machine clusters supporting a single database for greatest resource isolation
  • C. Multiple databases spanning a Bare Metal and Virtual Machine cluster to provide resource isolation and consolidation concurrently
  • D. A single database with one or more schema per application
  • E. Multiple Databases on a cluster
  • F. Bare Metal deployment with one database per database server

Answer: A,C,E

D Multiple databases spanning a Bare Metal and Virtual Machine cluster provide resource isolation and consolidation concurrently. It allows multiple databases to be deployed on both Bare Metal and Virtual Machine clusters, providing isolation and consolidation at the same time.
E Multiple Databases on a cluster allows multiple databases to be deployed on a single cluster, which enables consolidation of databases by reducing the number of clusters required.
