NEW QUESTION # 32
You have an extremely high performance database workload that requires atleast 105 IOPS/GB and 100,000 IOPS per volume.
Which Oracle Cloud Infrastructure (OCI) Block Volume performance level can be used to meet this requirement?
- A. Ultra High Performance
- B. Lower cost
- C. Higher Performance
- D. Balanced
Answer: A
Explanation:
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

NEW QUESTION # 36
Which statement about Oracle Cloud Infrastructure (OCI) shared security model is true?
- A. You are responsible for securing the hypervisor within OCI Compute service.
- B. You are responsible for managing security controls within the physical OCI network.
- C. You are responsible for securing all data that you place in OCI
- D. You are not responsible for any aspect of security in OCI.
Answer: C
Explanation:
Oracle Cloud Infrastructure offers best-in-class security technology and operational processes to secure its enterprise cloud services. However, for you to securely run your workloads in Oracle Cloud Infrastructure, you must be aware of your security and compliance responsibilities. By design, Oracle provides security of cloud infrastructure and operations (cloud operator access controls, infrastructure security patching, and so on), and you are responsible for securely configuring your cloud resources. Security in the cloud is a shared responsibility between you and Oracle.
In a shared, multi-tenant compute environment, Oracle is responsible for the security of the underlying cloud infrastructure (such as data-center facilities, and hardware and software systems) and you are responsible for securing your workloads and configuring your services (such as compute, network, storage, and database) securely.
In a fully isolated, single-tenant, bare metal server with no Oracle software on it, your responsibility increases as you bring the entire software stack (operating systems and above) on which you deploy your applications. In this environment, you are responsible for securing your workloads, and configuring your services (compute, network, storage, database) securely, and ensuring that the software components that you run on the bare metal servers are configured, deployed, and managed securely.
More specifically, your and Oracle's responsibilities can be divided into the following areas:
Identity and Access Management (IAM): As with all Oracle cloud services, you should protect your cloud access credentials and set up individual user accounts. You are responsible for managing and reviewing access for your own employee accounts and for all activities that occur under your tenancy. Oracle is responsible for providing effective IAM services such as identity management, authentication, authorization, and auditing.
Workload Security: You are responsible for protecting and securing the operating system and application layers of your compute instances from attacks and compromises. This protection includes patching applications and operating systems, operating system configuration, and protection against malware and network attacks. Oracle is responsible for providing secure images that are hardened and have the latest patches. Also, Oracle makes it simple for you to bring the same third-party security solutions that you use today.
Data Classification and Compliance: You are responsible for correctly classifying and labeling your data and meeting any compliance obligations. Also, you are responsible for auditing your solutions to ensure that they meet your compliance obligations.
Host Infrastructure Security: You are responsible for securely configuring and managing your compute (virtual hosts, containers), storage (object, local storage, block volumes), and platform (database configuration) services. Oracle has a shared responsibility with you to ensure that the service is optimally configured and secured. This responsibility includes hypervisor security and the configuration of the permissions and network access controls required to ensure that hosts can communicate correctly and that devices are able to attach or mount the correct storage devices.
Network Security: You are responsible for securely configuring network elements such as virtual networking, load balancing, DNS, and gateways. Oracle is responsible for providing a secure network infrastructure.
Client and Endpoint Protection: Your enterprise uses various hardware and software systems, such as mobile devices and browsers, to access your cloud resources. You are responsible for securing all clients and endpoints that you allow to access Oracle Cloud Infrastructure services.
Physical Security: Oracle is responsible for protecting the global infrastructure that runs all of the services offered in Oracle Cloud Infrastructure. This infrastructure consists of the hardware, software, networking, and facilities that run Oracle Cloud Infrastructure services.

NEW QUESTION # 39
What does compute instance horizonal scaling mean?
- A. backing up data to object storage
- B. stopping/starting the instance
- C. changing compute instance size
- D. adding additional compute instances
Answer: D
Explanation:
Cloud Horizontal Scaling refers to provisioning additional servers to meet your needs, often splitting workloads between servers to limit the number of requests any individual server is getting. In a cloud-based environment, this would mean adding additional instances instead of moving to a larger instance size.
Cloud Vertical Scaling refers to adding more CPU or memory to an existing server, or replacing one server with a more powerful server.
Reference:
https://cloudcheckr.com/cloud-cost-management/cloud-vs-data-center-what-is-scalability-in-cloud-computing/ Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.
An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.
With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool - Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and comes with an upper limit.
