You have a script with several CELLCLI commands that must be executed on each cell in your Exadata full rack. The script must run on each cell simultaneously. How must you achieve this?

Question

Options

• ACopy and execute the script on all storage servers using the EXACLI command.
• BCopy the script to all storage servers using the dcli command and manually execute it on all
• CCopy and execute the script on all storage servers using the dcli command.
• DCopy the script to all storage servers using the dcli command and manually execute it on each
• ECopy the script to all storage servers using the CELLCLI command and execute it on all storage

Explanation

dcli (Distributed Command Line Interface) is Exadata's purpose-built tool for running commands or scripts across multiple nodes simultaneously - it handles both copying and executing in a single operation, which is exactly what the question requires.

Why the distractors fail:

• A (EXACLI): EXACLI is a cell management utility accessed from database nodes, not a distributed execution tool - it cannot fan out script execution across all cells simultaneously.
• B & D: Both describe a two-phase manual process (copy first, then execute manually), which breaks the "simultaneously" requirement and defeats the purpose of automation.
• E: CELLCLI is a single-cell management CLI - it has no ability to copy or distribute scripts across multiple cells; it only operates locally on one cell.

Memory tip: Think of dcli as "Distribute and Command" - the "d" stands for distributed. Whenever an Exadata question asks you to run anything across all cells or nodes at once, dcli is almost always the answer. Its key strength is that one command can copy and execute simultaneously across your entire rack.
