Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q48-Q53):
NEW QUESTION # 48
Which two statements are true about the initial storage configuration after the standard (non-virtualized) deployment of a new Exadata Database Machine with High Capacity storage servers?
Answer: A,B
Explanation:
This is according to the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book [1]. The other statements are false as there is no free space available on the hard disks inside the database servers for possible extension of the /uoi file system, and there is no free space available on flashdisks inside the Exadata storage servers for possible use for storage indexes or to configure Exadata Smart Flash Logs [2][3].
NEW QUESTION # 49
You have been asked to design a backup solution for an Exadata X9M-2 Quarter Rack with Extreme Flash Storage Servers connected to a new ZFS Storage Appliance ZS7 with 2 Storage Controllers with 100Gb Ethernet cards and 3 Storage Trays. You are using Oracle Exadata Configuration Assistant to validate the rack layout.
1. Use "Add Equipment" to add the Exadata X9M EF Storage Servers, starting from RU10.
2. Use drop down to add ZFS Storage Appliance Controllers.
3. You cannot add ZFS Storage Appliance to an Exadata Rack.
4. Use "Add Equipment" to add the ZFS Storage Trays, starting from RU1.
5. Use drop down to add ZFS Storage Trays.
6. Use "Add Equipment" to add the Exadata X9M Database Servers, starting from RU16.
7. Use "Add Equipment" to add the Exadata X9M EF Storage Servers, starting from RU1.
8. Use drop down to add Exadata X9M EF Storage Servers.
9. Use "Add Equipment" to add the ZFS Storage Controllers, starting from RU27.
10. Use drop down to add Exadata X9M Database Servers.
11. Use "Add Equipment" to add the ZFS Storage Trays, starting from RU31.
Which of these steps are correct and what is their correct order?
Answer: A
Explanation:
The correct order of steps is 10, 8, 9, 11. The 10th step is to use the drop down to add Exadata X9M Database Servers, the 8th step is to use the drop down to add Exadata X9M EF Storage Servers, the 9th step is to use "Add Equipment" to add the ZFS Storage Controllers, and the 11th step is to use "Add Equipment" to add the ZFS Storage Trays. These steps are referenced in the Oracle Exadata Database Machine X9M Implementation Essentials Official Textbook, which is available online at https://docs.oracle.com/cd/E80437_01/E80437/html/index.html.
NEW QUESTION # 50
Which two statements are true about the types of Exadata X9M-2 storage servers: the High Capacity (HC) storage server, the Extreme Flash (EF) storage server and the Extended server?
Answer: B,E
Explanation:
High Capacity (HC) Storage Server: The Exadata X9M-2 HC storage server is configured with a combination of hard disks and flash memory, providing a balance of storage capacity and performance.
It includes 12 x 18 TB hard disk drives, which totals 216 TB of raw disk capacity.
For flash storage, it has 4 x 6.4 TB PCIe flash cards totaling 25.6 TB of flash storage. This configuration uses NVMe Flash Accelerator F680 cards optimized for database caching.
The persistent memory in the HC server totals 1.5 TB, enhancing performance for OLTP (Online Transaction Processing) workloads by providing ultra-fast access speeds compared to traditional flash storage.
Extreme Flash (EF) Storage Server: The EF storage server in the Exadata X9M-2 model is an all-flash storage server designed for high IOPS and low latency, making it ideal for performance-intensive workloads.
This configuration contains 8 x 6.4 TB PCIe flash cards, providing a raw capacity of 51.2 TB of high-performance flash storage.
In terms of persistent memory, it includes 756 GB of Intel Optane Persistent Memory. This enhances flash storage performance by offloading data processing directly to persistent memory.
The Exadata X9M-2 storage configurations-both HC and EF-are optimized for different workload requirements. The HC configuration caters to larger datasets needing high storage capacity, while the EF configuration is designed for workloads requiring high throughput and minimal latency.
NEW QUESTION # 51
You are planning the monitoring configuration for your Exadata X9M Database Machine.
Which three components are monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins?
Answer: A,D,F
Explanation:
Exadata-specific Enterprise Manager Plug-Ins are used to monitor different components of the Exadata Database Machine.
1. ASM instances: The Automatic Storage Management (ASM) instances can be monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins. This allows you to monitor the storage space, disk usage, and performance of the ASM instances.
2. Hybrid Columnar Compression (HCC) ratios on Extended (XT) storage servers: The HCC ratios on Extended (XT) storage servers can be monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins. This allows you to monitor the compression ratios and performance of the storage servers.
3. Oracle clusterware on the database server: The Oracle clusterware on the database server can be monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins. This allows you to monitor the health and performance of the clusterware.
NEW QUESTION # 52
Which are three customer options for hosting the Platinum Services Advanced Support Gateway?
Answer: A,D,E
Explanation:
These options are outlined in the Oracle Exadata Database Machine X9M Implementation Essentials official text book and resources. The customer can choose to either provide their own x86 64-Bit gateway hardware or purchase the recommended hardware from Oracle, or they can install the gateway on an Exadata Engineered System.
