NEW QUESTION # 17
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?
Answer: C
Explanation:
According to Oracle's documentation1, the Cell Control Command-Line Interface (CellCLI) utility is the command-line administration tool for Oracle Exadata System Software. It can be used to perform various tasks on Exadata Storage Servers, such as creating and managing objects, monitoring performance, and configuring alerts.
To run CELLCLI commands on multiple cells simultaneously, you can use the Distributed Command-Line Interface (dcli) utility2. The dcli utility allows you to execute commands or scripts on a group of cells or hosts in parallel. You can use the dcli utility to copy files from one cell or host to multiple cells or hosts using the -f option3. You can also use the dcli utility to execute commands or scripts on multiple cells or hosts using the -l option to specify a user name and the -g option to specify a file containing a list of cells or hosts3.
Therefore, to achieve your requirement of running a script with several CELLCLI commands on each cell in your Exadata full rack simultaneously, you must:
Copy and execute the script on all storage servers using the dcli command.

NEW QUESTION # 20
You have been asked to investigate why an Exadata Database Server stopped communicating on the client network for 10 minutes over the past weekend.
Which command would help investigate this?
Answer: B
Explanation:
Exachk is an Oracle-provided diagnostic tool that allows you to check various components of an Exadata Database Server, including the client network. The tool is located in the /opt/oracle.SupportTools/exachk/ directory and can be run with the command: exachk. This command can be run with the option -from _17:00:00 and -to _23:59:00 to specify a time range of interest, this way you can check the client network status between the specified time range. The tool checks the status of various components such as network interfaces, InfiniBand fabric, and storage servers. It also analyzes log files, configuration files, and system settings to detect any issues. The tool generates a report, which can be used to identify the root cause of the issue and provide recommendations for resolution.
Tfact1 is a tool to collect diagnostic information from Exadata and non-Exadata systems and it is not related to client network status.
Netcheck and GetExaWatcherResults.sh are not tools provided with the Exadata Database Server and they are not related to client network status.
NEW QUESTION # 21
An Exadata X9M-2 Elastic Rack with 4 Database Servers and 8 HC Storage Servers and 3-phase 24kVA PDUs is being installed in a Data Center. However, the Data Center is only providing enough power for a single cable from each PDU. Which statement is correct?
Answer: B
Explanation:
In order for an Exadata X9M-2 Elastic Rack to be installed, two power feeds are required for each of the three-phase 24kVA PDUs. A single cable from each PDU will not be enough to power the rack, and neither a splitter cable nor rearrangement of the power cables from the servers to the PDUs will be able to provide sufficient power for the system. Therefore, the installation cannot proceed until two power feeds are available per PDU.
