解説:
Explanation
Oracle Cloud Infrastructure's Autonomous Database is a fully managed, preconfigured database environment with two workload types available, Autonomous Transaction Processing and Autonomous Data Warehouse. You do not need to configure or manage any hardware, or install any software. After provisioning, you can scale the number of CPU cores or the storage capacity of the database at any time without impacting availability or performance. Autonomous Database handles creating the database, as well as the following maintenance tasks:
Backing up the database
Patching the database
Upgrading the database
Tuning the database

What two statements regarding the Virtual Cloud Network (VCN) are true?

- D. The VCN is the IPSec-based connection with a remote on premises location.
- E. VCN is a regional resource that span across all the Availability Domains in a Region.
正解: B,E
解説:
Explanation
When you work with Oracle Cloud Infrastructure, one of the first steps is to set up a virtual cloud network (VCN) for your cloud resources.
VIRTUAL CLOUD NETWORK (VCN) :
A virtual, private network that you set up in Oracle data centers. It closely resembles a traditional network, with firewall rules and specific types of communication gateways that you can choose to use. A VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice. See Allowed VCN Size and Address Ranges. The terms virtual cloud network, VCN, and cloud network are used interchangeably in this documentation. For more information, see VCNs and Subnets.
SUBNETS :
Subdivisions you define in a VCN (for example, 10.0.0.0/24 and 10.0.1.0/24). Subnets contain virtual network interface cards (VNICs), which attach to instances. Each subnet consists of a contiguous range of IP addresses that do not overlap with other subnets in the VCN. You can designate a subnet to exist either in a single availability domainavailability domain or across an entire region (regional subnets are recommended). Subnets act as a unit of configuration within the VCN: All VNICs in a given subnet use the same route table, security lists, and DHCP options (see the definitions that follow). You can designate a subnet as either public or private when you create it. Private means VNICs in the subnet can't have public IP addresses. Public means VNICs in the subnet can have public IP addresses at your discretion. See Access to the Internet.

質問 36
What does compute instance vertical scaling mean?
- A. Adding additional compute instances
- B. Enabling Disaster recovery
- C. Changing to a large or smaller shape
- D. Providing Fault tolerance
正解: C
解説:
Explanation
Changing the Shape of an Instance (Horizontal Scaling)
You can change the shape of a virtual machine (VM) instance without having to rebuild your instances or redeploy your applications. This lets you scale up your Compute resources for increased performance, or scale down to reduce cost.
Autoscaling (vertical scaling)
Autoscaling lets you automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.
As load increases, instances are automatically provisioned: the instance pool scales out. As load decreases, instances are automatically removed: the instance pool scales in.

質問 40
Which service is the most effective for moving large amounts of data from your on-premises to Oracle Cloud Infrastructure (OCI)?
- A. Internet Gateway
- B. Data Safe
- C. Dynamic Routing Gateway
- D. Data Transfer appliance
正解: D
解説:
Explanation
APPLIANCE-BASED DATA TRANSFER
You send your data as files on secure, high-capacity, Oracle-supplied storage appliances to an Oracle transfer site. Operators at the Oracle transfer site upload the data into your designated Object Storage bucket in your tenancy.
This solution supports data transfer when you are migrating a large volume of data and when using disks is not a practical alternative. You do not need to write any code or purchase any hardware. Oracle supplies the transfer appliance and software required to manage the transfer.

質問 41
Which OCI storage service does not provide encryption for data at rest?
- A. Local NVMe
- B. File Storage
- C. Object Storage
- D. Block Volume
正解: A
解説:
Explanation
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.
