Which three statements are true about the CELLCLI command?

Question

Options

• AIt can execute commands on multiple storage servers in parallel.
• BIt has command-line history.
• CIt requires root privileges to create CELLDISKS and GRIDDISKS.
• DIt can be executed on storage servers.
• EIt can be executed using the DCLI utility.

• A
  8% (5)
• B
  88% (53)
• C
  3% (2)

Explanation

B, D, E are correct because CELLCLI (Cell Command Line Interface) is a tool that runs directly on individual Exadata storage servers (cells) (D), supports command-line history via readline functionality (B), and can be invoked remotely by the DCLI (Distributed Command Line Interface) utility to run commands across one or more cells (E).

A is wrong because CELLCLI itself only operates on the local storage server - it has no built-in ability to fan out to multiple cells in parallel. That's exactly what DCLI is for.

C is wrong because CELLCLI does not require root privileges to create CELLDISKS or GRIDDISKS; the celladmin user has sufficient permissions for those operations.

Memory tip: Think of CELLCLI as a single-cell, local tool and DCLI as the distributed wrapper - if a statement describes multi-cell or remote behavior, it belongs to DCLI, not CELLCLI.
