Oracle Cloud Infrastructure Certification 1z0-1085-23 Exam Dumps

The primary goal of the Oracle Cloud Infrastructure shared security model is to ensure a comprehensive security posture by dividing security responsibilities between Oracle and the customer. Security in the cloud is a shared responsibility between you and Oracle. Whereas Oracle ensures the security of cloud infrastructure and operations, your organization must define its own security guidelines. The shared security model helps you understand which security tasks are handled by Oracle and which tasks you must perform3.

The Ultra High Performance level is the only OCI Block Volume performance level that can meet the requirement of at least 105 IOPS/GB and 100,000 IOPS per volume. The Ultra High Performance level is recommended for workloads with the highest I/O requirements, requiring the best possible performance. With this option, you can purchase between 30 – 120 VPUs (volume performance units) per GB/month. The VPUs determine the baseline performance of the volume, as well as the maximum burst performance. The Ultra High Performance level offers the following performance characteristics: 1

• Baseline IOPS/GB: 75
• Maximum IOPS/GB: 300
• Maximum IOPS per volume: 480,000
• Baseline throughput/GB: 0.6 MB/s
• Maximum throughput/GB: 2.4 MB/s
• Maximum throughput per volume: 3,680 MB/s

To achieve the requirement of at least 105 IOPS/GB, you need to purchase at least 45 VPUs/GB. To achieve the requirement of 100,000 IOPS per volume, you need to have a volume size of at least 334 GB. Therefore, the Ultra High Performance level can satisfy both requirements with a minimum volume size of 334 GB and a minimum VPUs/GB of 45.

The other performance levels (Balanced, Higher Performance, and Lower Cost) cannot meet the requirement of at least 105 IOPS/GB and 100,000 IOPS per volume. The Balanced level offers 10 VPUs/GB, with a baseline of 60 IOPS/GB and a maximum of 75 IOPS/GB. The Higher Performance level offers 20 VPUs/GB, with a baseline of 75 IOPS/GB and a maximum of 150 IOPS/GB. The Lower Cost level offers 2 VPUs/GB, with a baseline of 2 IOPS/GB and a maximum of 10 IOPS/GB. None of these levels can provide the required performance for the workload1
