質問 # 12
Which components are required to establish a Site-to-Site VPN connection in Oracle Cloud Infra-structure?
- A. Internet Gateway, Customer Premises Equipment (CPE), and IPsec tunnel
- B. Dynamic Routing Gateway (DRG), Customer Premises Equipment (CPE), and IPsec tunnel
- C. Internet Gateway (IG), Network Address Translation (NAT) Gateway, and IPsec tun-nel
- D. Dynamic Routing Gateway (DRG), NAT Gateway, and IPsec tunnel
正解：B
解説：
Site-to-Site VPN Components:
CPE OBJECT: At your end of Site-to-Site VPN is the actual device in your on-premises network (whether hardware or software). The term customer-premises equipment (CPE) is commonly used in some industries to refer to this type of on-premises equipment.
DYNAMIC ROUTING GATEWAY (DRG): At Oracle's end of Site-to-Site VPN is a virtual router called a dynamic routing gateway, which is the gateway into your VCN from your on-premises network.
IPSEC CONNECTION: After creating the CPE object and DRG, you connect them by creating an IPSec connection, which you can think of as a parent object that represents the Site-to-Site VPN.
TUNNEL: An IPSec tunnel is used to encrypt traffic between secure IPSec endpoints. Oracle cre-ates two tunnels in each IPSec connection for redundancy.
So, Internet Gateway, NAT Gateway are NOT valid Site-to-Site VPN Components.
Hence, Dynamic Routing Gateway (DRG), Customer Premises Equipment (CPE), and IPsec tunnel is the CORRECT answer.
質問 # 13
To achieve high availability in a 2-node RAC DB System in Oracle Cloud Infrastructure, what would you use to distribute your nodes to provide database instance fault isolation?
- A. Availability Domains
- B. Remote region
- C. Local region
- D. Fault Domains
正解：D
解説：
A fault domain is a grouping of hardware and infrastructure within an availability domain.
Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain.
To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time.
質問 # 14
Which is NOT an Azure resource that is created when you provision a database using Oracle Data-base Service for Azure?
- A. Custom Dashboard workspace
- B. Log Analytics workspace
- C. Oracle Database Service
- D. Application Insights workspace
正解：C
解説：
Log Analytics Workspace, Application Insights and Custom Dashboard are Azure resources and hence we can eliminate these options.
We are left with Oracle Database Service which is the CORRECT answer.
質問 # 15
What should you do to prepare your Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) for potential security risks when connected to a Microsoft Azure VNet?
- A. Limit all inbound and outbound traffic from the Azure VNet to expected and well-defined traffic.
- B. Allow all traffic from the Azure VNet without restrictions.
- C. Disable the connection between Azure VNet and OCI VCN.
- D. Remove all OCI security rules.
正解：A
解説：
Controlling Traffic Flow Over the Connection
Even if a connection has been established between your VCN and VNet, you can control the packet flow over the connection with route tables in your VCN. For example, you can restrict traf-fic to only specific subnets in the VNet.
Controlling the Specific Types of Traffic Allowed
It's important that you ensure that all outbound and inbound traffic with the VNet is intended or expected and well defined. Implement Azure network security group and Oracle security rules that explicitly state the types of traffic one cloud can send to the other and accept from the other.
質問 # 16
What is the purpose of the SAML metadata file in the OCI Federation setup with Azure Active Di-rectory (AD)?
- A. It is used to exchange metadata information between Azure AD and OCI.
- B. It is used to store user credentials for authentication.
- C. It is used to establish trust between Azure AD and OCI.
- D. It is used to configure attribute mapping between Azure AD and OCI.
正解：A
解説：
In general, SAML metadata is used to share configuration information between the Identity Pro-vider (IdP) and the Service Provider (SP).

Application Administrator, Cloud Application Administrator, Privileged Role Administrator, or Global Administrator.
質問 # 18
A company has deployed a multi-tier application in Oracle Cloud Infrastructure (OCI), with web servers in a public subnet and database servers in a private subnet. The database servers need to ac-cess data from OCI Object Storage, and the company wants to ensure that this communication is secure and not exposed to the public internet. Which OCI feature should be used to achieve this objective?
- A. Use a NAT Gateway to enable private access to Object Storage.
- B. Use a Local Peering Gateway to peer with the Object Storage subnet.
- C. Use a VPN Gateway to create an encrypted tunnel to Object Storage.
- D. Use a Service Gateway to establish a secure connection to Object Storage.
正解：D
解説：
A service gateway lets your virtual cloud network (VCN) privately access specific Oracle services without exposing the data to the public internet. No internet gateway or NAT gateway is required to reach those specific services.
The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the Oracle service travels over the Oracle network fabric and never traverses the internet.
質問 # 19
What does the term "multicloud" mean and how can it help organizations manage their IT infra-structure?
- A. The use of cloud services from multiple providers to leverage the best features and ser-vices of each
- B. The use of multiple cloud services from a single provider for redundancy and high availability
- C. The integration of on-premises infrastructure with cloud services for a hybrid cloud approach
- D. The deployment of a single cloud service across multiple regions and data centers for better performance
正解：A
解説：
The keyword here is multiple providers. Multicloud is a cloud computing strategy that uses the best services from more than one cloud provider to deploy a solution.
The use of multiple cloud services from a single provider for redundancy and high availability is INCORRECT as it talks about single provider.
The deployment of a single cloud service across multiple regions and data centers for better perfor-mance is also INCORRECT as there is no mention of multiple cloud service providers. Rather it talks about single cloud service across multiple regions.
The use of multiple cloud services from a single provider for redundancy and high availability is al-so INCORRECT as it also talks about single provider.
Hence the correct answer is The use of cloud services from multiple providers to leverage the best features and services of each.
質問 # 20
An organization wants to deploy Oracle Database Service for Azure in the existing Oracle Cloud Infrastructure and Azure tenancies that are in the supported regions. However, they want to have full control over the Azure permissions that should be granted.
Which option should they choose during the sign-up process?
- A. Fully scripted configuration
- B. Auto pilot linking
- C. Fully automated configuration
- D. Guided account linking
正解：D
解説：
The keyword mentioned in the question is "However, they want to have full control over the Az-ure permissions that should be granted. " The fully-automated onboarding option for OracleDB for Azure is faster and more convenient than the guided account linking, but some organizations may have security policies that do not allow them to grant the required permissions to the Oracle Database Service enterprise applica-tion that runs in their Azure account.
Guided onboarding is provided for customers who do not want to grant OracleDB for Azure all the Azure permissions required for fully automated onboarding.
The remaining two options - Auto pilot linking and Fully scripted configuration are INVALID. There doesn't exist anything like these in Oracle Database Service for Azure onboarding.
Hence the correct answer is Guided account linking
質問 # 21
An organization has decided to implement a multicloud solution by using Microsoft Azure for their frontend data analytics applications and Oracle Cloud Infrastructure (OCI) for their backend Oracle Autonomous Data Warehouse. In this scenario, how can the organization ensure secure and low la-tency data transfer between the frontend applications and the backend data warehouse?
- A. Establish a dedicated, private connection between Azure and OCI using Azure Ex-pressRoute and Oracle FastConnect.
- B. Leverage a VPN Gateway to create an encrypted tunnel between Azure and OCI for secure data transfer.
- C. Use public internet connections to transfer data between Azure and OCI, encrypting the data in transit.
- D. Implement a hybrid cloud approach by integrating on-premises infrastructure with both Azure and OCI.
正解：A
解説：
In the question, frontend is in Azure and backend is in OCI. And the keywords are SECURE and LOW LATENCY data transfer.
Use public internet connections to transfer data between Azure and OCI, encrypting the data in transit - INCORRECT as this option won't provide LOW LATENCY data transfer (as it is us-ing public internet).
Leverage a VPN Gateway to create an encrypted tunnel between Azure and OCI for secure data transfer - INCORRECT as Site-to-Site VPN Connection won't provide LOW LATENCY data transfer as the connection traverses through public internet.
Implement a hybrid cloud approach by integrating on-premises infrastructure with both Azure and OCI - INCORRECT as there is no mention of on-premises environment in the question. This option is irrelevant here.
Establish a dedicated, private connection between Azure and OCI using Azure ExpressRoute and Oracle FastConnect - CORRECT as it provides a direct Interconnect between OCI and Microsoft Azure which in turn provides <2ms latency for superior multicloud network performance.
質問 # 22
Which type of traffic is NOT supported by the OCI-Azure Interconnect?
- A. Traffic between an Azure VNet and an OCI VCN
- B. Traffic between an on-premises network and Azure VNet through the OCI VCN
- C. Traffic between an Azure VNet and peered OCI VCNs in different regions
- D. Traffic between an Azure VNet and peered OCI VCNs in the same region
正解：B
解説：
You can connect your VNet and VCN so that traffic that uses private IP addresses goes over the cross-cloud connection.
The connection enables traffic to flow from the VNet through the connected VCN to a peered VCN in the same Oracle Cloud Infrastructure region, or a different region.
The Cross-cloud connection does not enable traffic between your on-premises network through the VCN to the VNet, or from your on-premises network through the VNet to the VCN.
質問 # 23
How do Azure administrators and developers connect their applications to Oracle databases using Oracle Database Service for Azure?
- A. By learning OCI and working in the OCI Console
- B. By connecting to the Oracle databases using connection strings
- C. By connecting to the Oracle databases using database links
- D. By manually creating complex cross-cloud deployments using the Interconnect
正解：B
解説：
The same way you do in Azure today. Each database resource created by Oracle Database Service for Azure gets an Azure connection string you can use to connect to the database from any Azure application.
During onboarding, Oracle Database Service for Azure creates network connections between the cloud environments.
During database provisioning, Oracle Database Service for Azure defines the DNS entries and connection strings needed to access the resource from Azure.
Azure developers (and applications) don't need to know anything about Oracle Database Service for Azure-all they need is the connection string. Oracle publishes the connection string on the custom dashboard it creates for the database in Azure, so developers don't have to leave the Azure portal to get what they need to access the database from their applications.
Hence, the CORRECT ANSWER is "By connecting to the Oracle databases using connection strings"
質問 # 24

解説：
VIRTUAL CIRCUIT is an isolated network path that runs over one or more physical network connections to provide a single, logical connection between the edge of your existing network and Oracle Cloud Infrastructure. Private virtual circuits support private peering, and public virtual circuits support public peering.
質問 # 27
An enterprise has a workload running in a VNet in Microsoft Azure and a database running in a VCN in Oracle Cloud Infrastructure. The enterprise wants to set up a private, secure, and isolated network connection between the two clouds to enable traffic flow between the workload and the database. Which option can be used to achieve this requirement?
- A. Use Azure Private Link to create a private connection between the workload and the database.
- B. Use Azure VPN and Oracle FastConnect to establish a private and secure tunnel be-tween the Azure VNet and the OCI VCN.
- C. Use Azure ExpressRoute and Oracle FastConnect to create a private interconnection between the Azure VNet and the OCI VCN.
- D. Use public internet to establish connectivity between the Microsoft Azure VNet and the OCI VCN.
正解：C
解説：
As per the question, the keywords are "The enterprise wants to set up a private, secure, and isolat-ed network connection between the two clouds" Use public internet to establish connectivity between the Microsoft Azure VNet and the OCI VCN - INCORRECT as this option won't provide private, secure and isolated connection.
Use Azure VPN and Oracle FastConnect to establish a private and secure tunnel between the Azure VNet and the OCI VCN is INCORRECT as it won't provide a isolated connection.
Use Azure Private Link to create a private connection between the workload and the database is INCORRECT as Azure Private Link enables you to access Azure PaaS Services (for example, Azure Storage and SQL Database) and Azure hosted customer-owned/partner services over a pri-vate endpoint in your virtual network.
Use Azure ExpressRoute and Oracle FastConnect to create a private interconnection between the Azure VNet and the OCI VCN. is CORRECT. To create an integrated multi-cloud experience, Microsoft and Oracle offer direct interconnection between Azure and Oracle Cloud Infrastructure (OCI) through ExpressRoute and FastConnect. Through the ExpressRoute and FastConnect inter-connection, customers can experience low latency, high throughput, private direct connectivity be-tween the two clouds.
