NEW QUESTION # 67
Which of the below is NOT a precaution that should be adhered to in order to ensure the site is safe and ready for

A. Do not install Oracle Exadata Rack in a location that is exposed to direct sunlight.
B. When using shared grounding, the grounding resistance must not be greater than 10 ohms.
C. Do not place anything on top of Oracle Exadata Rack.
D. Do not use a flathead screwdriver to disconnect connector locks on LAN cables.
E. Be sure that each grounding wire used for Oracle Exadata Rack is used exclusively for Oracle Exadata Rack.
F. Do not install Oracle Exadata Rack near a photocopy machine.

Answer: F

Explanation:
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.

NEW QUESTION # 68
You are monitoring PMEM cache to see if it is being used effectively with RDMA. Which two of these sources contain information about the RDMA I/O statistics?

A. Database lOs section in AWR Report
B. PMEM Cache Space Usage section in AWR Report
C. Exadata Metrics (LIST METRICCURRENT)
D. Database Statistics (v$ View)
E. PMEM Cache User Reads section in AWR Report

Answer: C,E

Explanation:
To monitor the effectiveness of Persistent Memory (PMEM) cache usage with RDMA on Exadata, information on RDMA I/O statistics can be found in:
PMEM Cache User Reads section in the AWR Report: This section provides detailed statistics on PMEM read operations, including user reads that leverage RDMA for direct memory access from PMEM. These metrics help gauge the utilization and efficiency of the PMEM cache.
Exadata Metrics (LIST METRICCURRENT): By using the LIST METRICCURRENT command within the Exadata environment, real-time metrics related to PMEM usage and RDMA I/O statistics can be accessed. This provides an immediate view of the current performance and activity on Exadata's persistent memory components.
These tools together offer insights into PMEM cache usage and the effectiveness of RDMA for optimized data access.

NEW QUESTION # 69

6. Power off the rack using the power switches on the PDUs.
7. Execute "shutdown -h now" on all database servers.
8. Execute "shutdown -h now" on all Exadata storage servers.
Which is the correct order or the required commands to completely power off an Exadata Database Machine in an orderly fashion?

A. 5, 8, 7, and 6
B. 2, 8, 7, 3, and 6
C. 4, 7, 8, 3, and 6
D. 2, 7, 8, and 6
E. 1, 8, 7, 3 and 6

Answer: E
