Explanation:
The exadcli utility runs commands on multiple remote nodes in parallel threads.
You can issue an ExaCLI command to be run on multiple remote nodes. Remote nodes are referenced by their host name or IP address. Unlike dcli, exadcli can only execute ExaCLI commands. Other commands, for example, shell commands, cannot be executed using exadcli.
Incorrect Answers:
A: Note that exadcli runs ExaCLI in a “no-prompt” mode. This means that if user interaction is needed (for example, if you need to enter a password or if you need to verify that the certificate from a remote node is valid), then exadcli will exit with an error.
