質問 # 82
A customer is looking to migrate their old database backups from their on-premises data center to Oracle Cloud Infrastructure (OCI). Which OCI service is the most cost-effective?
- A. Block Volume
- B. Object Storage (standard)
- C. File Storage
- D. Archive Storage
正解：D
解説：
Archive storage is the most cost effective for archive data
Reference:
https://www.oracle.com/cloud/storage/archive-storage.html
Oracle Cloud Infrastructure offers two distinct storage class tiers to address the need for both performant, frequently accessed "hot" storage, and less frequently accessed "cold" storage. Storage tiers help you maximize performance where appropriate and minimize costs where possible.
1) Use Archive Storage for data to which you seldom or rarely access, but that must be retained and preserved for long periods of time. The cost efficiency of the Archive Storage offsets the long lead time required to access the data.
2) Use Object Storage for data to which you need fast, immediate, and frequent access. Data accessibility and performance justifies a higher price to store data in the Object Storage. For more information, see Overview of Object Storage.
質問 # 83

質問 # 86
Which Oracle Cloud Infrastructure (OCI) service can send you an alert when you might exceed your spending threshold?
- A. Budgets
- B. Events
- C. Streaming
- D. Monitoring
正解：A
解説：
Budgets can be used to set thresholds for your Oracle Cloud Infrastructure spending. You can set alerts on your budget to let you know when you might exceed your budget, and you can view all of your budgets and spending from one single place in the Oracle Cloud Infrastructure console.
Reference:
https://docs.cloud.oracle.com/en-us/iaas/Content/Billing/Concepts/billingoverview.htm A budget can be used to set soft limits on your Oracle Cloud Infrastructure spending. You can set alerts on your budget to let you know when you might exceed your budget, and you can view all of your budgets and spending from one single place in the Oracle Cloud Infrastructure console.
How Budgets Work:
Budgets are set on cost-tracking tags or on compartments (including the root compartment) to track all spending in that cost-tracking tag or for that compartment and its children.
All budgets alerts are evaluated every 15 minutes. To see the last time a budget was evaluated, open the details for a budget. You will see fields that show the current spend, the forecast and the "Spent in period" field which shows you the time period over which the budget was evaluated. When a budget alert fires, the email recipients configured in the budget alert receive an email.

Only Oracle offers end-to-end SLAs covering performance, availability, manageability of services.
質問 # 92
Which OCI storage service does not provide encryption for data at rest?
- A. Block Volume
- B. Local NVMe
- C. File Storage
- D. Object Storage
正解：B
解説：
NVMe stands for non-volatile memory express. It is a storage protocol created to fasten the transfer of data between enterprise and client systems and solid-state drives (SSDs) over a computer's high-speed Peripheral Component Interconnect Express bus. The characteristics are:
1) Local NVMe is NVMe SSD-based temporary storage.
2) It is the locally-attached NVMe devices to the OCI compute instance
3) It is used very high storage performance requirements, lots of throughput, lots of IOPS, local storage and when you don't want to go out on network
4) Oracle does not protect in any way through RAID, or snapshots, or backup out of the box and data is not encrypted at rest.

質問 # 99
What does compute instance horizonal scaling mean?
- A. adding additional compute instances
- B. backing up data to object storage
- C. changing compute instance size
- D. stopping/starting the instance
正解：A
解説：
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.
質問 # 100
Which statement below is not true for Oracle Cloud infrastructure Compartments?
- A. Compartments cannot be nested
- B. Each OCI resource belongs to a single compartment
- C. Resources can be moved from one compartment to another
- D. Resources and compartments can be added and deleted anytime
正解：A
解説：
When creating a compartment, you must provide a name for it (maximum 100 characters, including letters, numbers, periods, hyphens, and underscores) that is unique within its parent compartment. You must also provide a description, which is a non-unique, changeable description for the compartment, from 1 through 400 characters. Oracle will also assign the compartment a unique ID called an Oracle Cloud ID.
You can create subcompartments in compartments to create hierarchies that are six levels deep.
Reference:
https://docs.cloud.oracle.com/en-us/iaas/Content/Identity/Tasks/managingcompartments.htm When you first start working with Oracle Cloud Infrastructure, you need to think carefully about how you want to use compartments to organize and isolate your cloud resources. Compartments are fundamental to that process. Most resources can be moved between compartments. However, it's important to think through your compartment design for your organization up front, before implementing anything. For more information, see Setting Up Your Tenancy.
The Console is designed to display your resources by compartment within the current region. When you work with your resources in the Console, you must choose which compartment to work in from a list on the page. That list is filtered to show only the compartments in the tenancy that you have permission to access. If you're an administrator, you'll have permission to view all compartments and work with any compartment's resources, but if you're a user with limited access, you probably won't.
Compartments are tenancy-wide, across regions. When you create a compartment, it is available in every region that your tenancy is subscribed to. You can get a cross-region view of your resources in a specific compartment with the compartment explorer. See Viewing All Resources in a Compartment.
You can create subcompartments in compartments to create hierarchies that are six levels deep.
