質問 # 31
A customer wants to use Oracle Cloud Infrastructure (OCI) storing application backups which can be stored for months, but retrieved immediately based on business needs. Which OCI storage service can be used to meet this requirement?
- A. Block Volume
- B. Archive Storage
- C. File Storage
- D. Object Storage (standard)
正解：D
解説：
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.
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 tier.
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 tier offsets the long lead time required to access the data.
Unlike Object Storage, Archive Storage data retrieval is not instantaneous.

質問 # 32
A new customer has logged into Oracle Cloud Infrastructure (OCI) as an administrator for the first time. The admin would like to deploy Infrastructure into a region other then their home region.
What is the first Stop they must take in order to accomplish this task?
- A. Navigate to the desired region and begin creating resources.
- B. File a service request for access to each additional region.
- C. Use API endpoints to create resources in the desired region.
- D. Subscribe to the desired region.
正解：D
解説：
When you sign up for Oracle Cloud Infrastructure, Oracle creates a tenancy for you in one region. This is your home region. Your home region is where your IAM resources are defined. When you subscribe to another region, your IAM resources are available in the new region, however, the master definitions reside in your home region and can only be changed there.
When you subscribe your tenancy to a new region, all the policies from your home region are enforced in the new region. If you want to limit access for groups of users to specific regions, you can write policies to grant access to specific regions only.
Reference:
https://docs.cloud.oracle.com/en-us/iaas/Content/Identity/Tasks/managingregions.htm To create an instance in another region, perform these preliminary steps:
1. Extend your subscription to another region.
2. Federate Oracle Identity Cloud Service (IDCS) from the new region with Oracle Cloud Infrastructure (OCI).
Also, when you purchase these services or sign up for a free promotion, you typically choose the data region closest to your location to access them. This becomes your primary data region. However, if required, you can extend your subscription to other geographical regions (within the same cloud account) and use the services there.

- A. OCI Resource Manager
- B. OCI Registry
- C. OCI Marketplace
- D. OCI OS Management
正解：C
解説：
Oracle Cloud Infrastructure Marketplace is an online store that offers solutions specifically for customers of Oracle Cloud Infrastructure. In the Oracle Cloud Infrastructure Marketplace catalog, you can find listings for two types of solutions from Oracle and trusted partners: images and stacks. These listing types include different categories of applications. Also, some listings are free and others require payment.
Images are templates of virtual hard drives that determine the operating system and software to run on an instance. You can deploy image listings on an Oracle Cloud Infrastructure Compute instance. Marketplace also offers stack listings. Stacks represent definitions of groups of Oracle Cloud Infrastructure resources that you can act on as a group. Each stack has a configuration consisting of one or more declarative configuration files. With an image or a stack, you have a customized, more streamlined way of getting started with a publisher's software.

質問 # 37
What is Oracle's responsibility according to the Oracle Cloud Infrastructure (OCI) shared-security model?
- A. Security of data center facilities
- B. Data classification and compliance
- C. Configuring OCI services securely
- D. Securing application workloads
正解：A
解説：
Oracle's mission is to build cloud infrastructure and platform services for your business to have effective and manageable security to run your mission-critical workloads and store your data with confidence.
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:
質問 # 38
What does compute instance horizonal scaling mean?
- A. backing up data to object storage
- B. adding additional compute instances
- C. stopping/starting the instance
- D. changing compute instance size
正解：B
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 # 39
Which OCI storage service does not provide encryption for data at rest?
- A. Block Volume
- B. File Storage
- C. Local NVMe
- D. Object Storage
正解：C
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 # 40

- A. Add or change a tenancy administrator
- B. Troubleshoot your resources in an Oracle Cloud Infrastructure Free Trial account
- C. Reset the password or unlock the account for the tenancy administrator
- D. Request a Service Limit increase
正解：B
解説：
Open a support service request with MOS option is available to paid accounts. Customers using only Always Free resources are not eligible for Oracle Support. Limited support is available to Free Tier accounts with Free Trial credits. After you use all of your credits or after your trial period ends (whichever comes first), you must upgrade to a paid account to access Oracle Support. If you choose not to upgrade and continue to use Always Free Services, you will not be eligible to raise a service request in My Oracle Support.
In addition to support for technical issues, use My Oracle Support if you need to:
* Reset the password or unlock the account for the tenancy administrator
* Add or change a tenancy administrator
* Request a service limit increase

質問 # 50
Which statement is correct regarding the oracle cloud infrastructure Compute services?
- A. You can attach a maximum of one public to each compute instance
- B. When you stop a compute instance, all data on the boot volume is lost
- C. You can launch either virtual machines or bare metal instances
- D. You cannot attach a block volume to a compute instance
正解：C
解説：
Oracle Cloud Infrastructure Compute lets you provision and manage compute hosts, known as instances
. You can launch instances as needed to meet your compute and application requirements. After you launch an instance, you can access it securely from your computer, restart it, attach and detach volumes, and terminate it when you're done with it. Any changes made to the instance's local drives are lost when you terminate it. Any saved changes to volumes attached to the instance are retained.
Oracle Cloud Infrastructure offers both bare metal and virtual machine instances:
1) Bare Metal: A bare metal compute instance gives you dedicated physical server access for highest performance and strong isolation.
2) Virtual Machine: A virtual machine (VM) is an independent computing environment that runs on top of physical bare metal hardware. The virtualization makes it possible to run multiple VMs that are isolated from each other. VMs are ideal for running applications that do not require the performance and resources (CPU, memory, network bandwidth, storage) of an entire physical machine.
An Oracle Cloud Infrastructure VM compute instance runs on the same hardware as a bare metal instance, leveraging the same cloud-optimized hardware, firmware, software stack, and networking infrastructure.
質問 # 51
Which resource do you manage in an Infrastructure-as-a-services (IAAS) offering?
- A. Storage
- B. Servers
- C. Operating system
- D. Network
正解：C
解説：
Infrastructure as a service (IaaS) is a type of cloud service model in which computing resources are hosted in the cloud. Businesses can use the IaaS model to shift some or all of their use of on-premises or colocated data center infrastructure to the cloud, where it is owned and managed by a cloud provider. These infrastructure elements can include compute, network, and storage hardware as well as other components and software.
How Does IaaS Work?
In a typical IaaS model, a business-which can be of any size-consumes services like compute, storage, and databases from a cloud provider. The cloud provider offers those services by hosting hardware and software in the cloud. The business will no longer need to purchase and manage its own equipment, or space to host the equipment, and the cost will shift to a pay-as-you-go model. When the business needs less, it pays for less. And when it grows, it can provision additional computing resources and other technologies in minutes.
