Answer: A

Explanation:
https://docs.oracle.com/en/engineered-systems/exadata-database-machine/dbmmn/maintaining-exadata-database-servers.html According to Oracle's documentation1, one of the utilities for diagnostics and repair of Oracle Exadata Storage Server is ExaWatcher, which collects operating system and network metrics on database servers and storage servers. The utility is located in the /opt/oracle.ExaWatcher directory1.
To investigate why an Exadata Database Server stopped communicating on the client network for 10 minutes over the past weekend, you can use the GetExaWatcherResults.sh script to collect and analyze ExaWatcher data for a specified time range1.
Therefore, the command that you should use to investigate this is:
/opt/oracle.ExaWatcher/GetExaWatcherResults.sh -from <Fridays_Date>_17:00:00 -to <Sundays_Date>_23:59:00
