NEW QUESTION # 71
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?

A. The EF storage server contains 8 x 6.4 TB PCIe flash cards, and can be upgraded with 4 more for a total of 12.
B. The EF storage server contains 8 x 6.4 TB PCIe flash cards and 756 GB Persistent Memory.
C. The HC storage server contains 12 x 18 TB hard disks, 4 x 6.4 TB PCIe flash cards, and 1.5 TB Persistent Memory.
D. The XT storage server is an all-disk storage server with no flash, containing 12 x 18 TB hard disks, and 1.5 TB Persistent Memory.
E. The EF storage server contains 8 x 6.4 TB PCIe flash cards.

Answer: B,C

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.

B. When running a "yum update" for a new Exadata release, all other repositories should be disabled.
C. Failed database server updates are rolled back to a working state on a previous release automatically.
D. To speed up applying storage server updates in a rolling manner, updating two storage servers simultaneously is recommended.
E. For regular Exadata updates, yum automatically installs a non-UEK kernel, which can be selected to boot from grub.
F. Failed storage server updates are automatically rolled back to a previous release.

Answer: E,F

Explanation:
1. Exadata updates have a rollback feature in case the update fails, this means that the system will roll back to a previous release automatically, this applies to storage servers updates. D. Yum, the package manager used in Exadata, automatically installs a non-UEK kernel when running a regular update, this kernel can be selected to boot from grub.

A. Oracle Linux 7.9
B. Oracle Linux 7.7
C. Oracle Linux 8.0
D. Oracle Linux 7.5

Answer: A

Explanation:
Oracle Linux 7.9 is the minimum version required to support RoCE and Persistent Memory. This is because Oracle Linux 7.9 includes kernel enhancements that enable RDMA over Converged Ethernet (RoCE) networking and Intel Optane DC Persistent Memory Modules (DCPMM) for Exadata X8M systems3. These features allow faster access latency and higher throughput for database workloads2.
