Which of the below is NOT a precaution that should be adhered to in order to ensure the site is safe and ready for
Correct : C
When preparing a site for an Exadata Database Machine, several precautions ensure both the safety of the installation and the optimal performance of the equipment. These precautions include:
Avoiding High-Interference Equipment: Installing near devices like photocopy machines, which can emit electromagnetic interference (EMI), is not a specified precaution for Exadata installations. However, attention should be given to site requirements for temperature, power, and proper grounding connections .
In contrast, other site requirements include exclusive grounding for Exadata racks, avoiding direct sunlight exposure, and ensuring grounding resistance is less than 10 ohms for shared grounding to minimize electrical risks.

When receiving an Exadata Database Machine rack on site, which of the following statements is INCORRECT?
Correct : E
The handling and installation of an Exadata Database Machine rack require caution and adherence to recommended guidelines:
Shipping Brackets: Shipping brackets are specifically designed for transportation purposes and should not be reused for permanent installation. Permanent floor mounting should use approved rack-mounting equipment to ensure stability and safety .
Steering and Pushing the Rack: Exadata racks should be steered from the rear due to fixed front casters. It is critical to avoid pushing the rack from the side panels, which could cause it to tip over, presenting a serious safety risk. This careful movement ensures safe positioning and prevents damage to the equipment during installation.

You want to examine how much Smart Scan activity is occurring.
Which two would provide the information you require?
Correct : B, E
To determine the amount of Smart Scan activity on an Exadata Database Machine, you can access two specific commands:
CELLCLI Command: Using the list activerequest command within CELLCLI on all storage cells will show the number of Smart Scans being processed. CELLCLI is an interface specific to Exadata Storage Servers for management and monitoring, and it provides real-time visibility into ongoing Smart Scan operations .
EXACLI Command: Similarly, the list ACTIVEREQUEST command using EXACLI on all storage cells also lists the Smart Scans executed across the storage servers. EXACLI is a remote command-line utility that can be run from a database server to manage storage cells, offering convenient access to similar Smart Scan information .

What does the following command do?
root@rul6 -]# for j in {01..23} ; do ipmitool sunoem cli "set /SP/network/test ping=192.168.1.1$j'' ; done
Correct : B
The given command uses a for loop with ipmitool to issue ping commands sequentially to a range of IP addresses in the management network:
for j in {01..23}; do ipmitool sunoem cli 'set /SP/network/test ping=192.168.1.1$j'; done
This script verifies the connectivity of the ILOM management network before the Exadata installation. Each server's Service Processor (SP) is tested for reachability, confirming that the management network setup is operational across the full rack .
