質問 # 24
A company wants to seamlessly build a private interconnection between their OCI and Microsoft Azure environments with consistent performance and low latency. They want to enable their cloud engineers to set up Single Sign-On (SSO) between Microsoft Azure and OCI for their Oracle appli-cations, such as PeopleSoft, JD Edwards EnterpriseOne, and E-Business Suite.
Which technology integration can the company use to achieve this goal?
- A. OCI Site-to-Site VPN and Azure Site-to-Site VPN
- B. Direct Connect and Azure VPN Gateway
- C. Cloud Interconnect and Virtual WAN
- D. Oracle FastConnect and Azure ExpressRoute
正解：D
解説：
By using Oracle FastConnect and Azure ExpressRoute, customers can seamlessly build a private interconnection between their OCI and Microsoft Azure environments. The Interconnect also ena-bles joint customers to take advantage of a unified identity and access management platform that leads to cost savings. Cloud engineers can set up SSO between Microsoft Azure and OCI for their Oracle applications, such as PeopleSoft, JD Edwards EnterpriseOne, and E-Business Suite. Having a federated SSO makes the integration seamless and allows users to authenticate only once to access multiple applications, without signing in separately to access each application.
質問 # 25
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. Disable the connection between Azure VNet and OCI VCN.
- B. Remove all OCI security rules.
- C. Allow all traffic from the Azure VNet without restrictions.
- D. Limit all inbound and outbound traffic from the Azure VNet to expected and well-defined traffic.
正解：D
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 # 26
What encryption protocol is used to secure data transmission in an OCI Site-to-Site VPN connec-tion?
- A. Internet Protocol Security (IPSec)
- B. Transport Layer Security (TLS)
- C. Datagram Transport Layer Security (DTLS)
- D. Secure Sockets Layer (SSL)
正解：A
解説：
Site-to-Site VPN provides a site-to-site IPSec connection between your on-premises network and your virtual cloud network (VCN). The IPSec protocol suite encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives.
質問 # 27
What does the term "multicloud" mean and how can it help organizations manage their IT infra-structure?
- A. The use of multiple cloud services from a single provider for redundancy and high availability
- B. The use of cloud services from multiple providers to leverage the best features and ser-vices of each
- 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：B
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 # 28
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. Auto pilot linking
- B. Fully scripted configuration
- 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 # 29
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 configure attribute mapping between Azure AD and OCI.
- D. It is used to establish trust 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).
質問 # 30
Which is true regarding fully automated and guided onboarding for the OracleDB for Azure ser-vice?
- A. Guided onboarding is simpler and faster than fully automated onboarding.
- B. Fully automated onboarding requires more permissions to be granted than guided onboarding.
- C. An Azure user who completes guided onboarding cannot log in to the OracleDB for Azure portal.
- D. An Azure user who completes fully automated onboarding can log in to the OracleDB for Azure portal, but cannot deploy and provision databases.
正解：B
解説：
The fully-automated onboarding option for OracleDB for Azure is faster and more convenient than the guided account linking. Hence the option "Guided onboarding is simpler and faster than fully automated onboarding" is NOT TRUE.
When the automated configuration finishes, OracleDB for Azure is fully operational. The Azure user that completed onboarding can login and use the OracleDB for Azure portal to deploy and provision databases for use in their Azure environment. Hence the option "An Azure user who completes fully automated onboarding can log in to the OracleDB for Azure portal, but cannot de-ploy and provision databases" is NOT TRUE.
If you used the guided onboarding process, the user who completed onboarding can login to the OracleDB for Azure portal, but not really do anything there. Before users can do anything produc-tive using OracleDB for Azure, you must first complete configuration steps for each user or user group. Hence the option "An Azure user who completes guided onboarding cannot log in to the Or-acleDB for Azure portal" is NOT TRUE.
Now, let's look at the only option left which is "Fully automated onboarding requires more permis-sions to be granted than guided onboarding". This option is TRUE as the automated onboarding process requires that the Azure user onboarding to OracleDB for Azure have at least one of the fol-lowing admin roles: Application Administrator, Cloud Application Administrator, Privileged Role Administrator, or Global Administrator. Guided onboarding is provided for customers who do not want to grant OracleDB for Azure all the Azure permissions required for fully automated onboard-ing. Hence this is the correct answer.
質問 # 31
Which is NOT an Azure resource that is created when you provision a database using Oracle Data-base Service for Azure?
- A. Oracle Database Service
- B. Custom Dashboard workspace
- C. Log Analytics workspace
- D. Application Insights workspace
正解：A
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 # 32
Which is a database service that CANNOT be provisioned in the Oracle Public Cloud?
- A. Autonomous Database on Shared Infrastructure
- B. Autonomous Database on Dedicated Infrastructure
- C. Exadata Database Service on Dedicated Infrastructure
- D. Exadata Database Service on Shared Infrastructure
正解：D
解説：
As you can see in the screenshot, Exadata Database Service on Shared Infrastructure is NOT sup-ported.
質問 # 33

To start OracleDB for Azure onboarding, go to https://signup.multicloud.oracle.com/azure
質問 # 34
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 Service Gateway to establish a secure connection 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 NAT Gateway to enable private access to Object Storage.
正解：A
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 # 35
What is the purpose of identity federation in the context of OracleDB for Azure?
- A. To enable bidirectional communication between applications in the Azure tenancy and the database resources in OracleDB for Azure
- B. To provide a way for customers to manage database resources in OracleDB for Azure without using the OCI Console
- C. To link Azure subscriptions to your OCI tenancy
- D. To allow users to log in to the OCI Console using the same Azure credentials
正解：D
解説：
Azure users log into OracleDB for Azure using their Azure credentials, and OracleDB for Azure streams much of the day-to-day operational data from the OracleDB for Azure managed OCI data-bases to Azure Application Insights and Azure Log Analytics. Because of this, Azure developers spend most of their time in Azure.
In some instances, an OracleDB for Azure user must log into the OCI Console to perform specific tasks that aren't enabled or available in OracleDB for Azure today. To make this process easier, Az-ure customers setup identity federation between the Azure and OCI tenancies. With this in place, authorized users use a single set of credentials, their Azure credentials, to log into Azure and OCI
質問 # 36
What is the primary purpose of an Oracle Cloud Infrastructure Identity Domain?
- A. Establish a secure, private connection between the tenancy and other Oracle Cloud ser-vices.
- B. Provide a centralized location for storing and managing user credentials and access.
- C. Create isolated networks for resources within the tenancy for enhanced security.
- D. Define the roles and privileges assigned to a user or group of users within the tenancy.
正解：B
解説：
Oracle Cloud Infrastructure (OCI) Identity Domain is the access control plane for Oracle Cloud. An identity domain is a container for managing users and roles, federating and provisioning of users, secure application integration through Oracle Single Sign-On (SSO) configuration, and SAML and OAuth based Identity Provider administration.
質問 # 37
What is NOT required for the OracleDB for Azure setup?
- A. An existing Azure account with the necessary ARM roles
- B. A preprovisioned Azure Virtual Network (VNet)
- C. Specific roles for the Oracle Database Service (ODS) enterprise application in Azure
- D. An OCI tenancy with the necessary admin permissions for the OCI user
正解：B
解説：
To set up and use OracleDB for Azure, you need an existing Azure account with the necessary Azure roles. Hence "An existing Azure account with the necessary ARM roles" is required.
If you already have an OCI account, you can use that account to onboard with OracleDB for Az-ure. Be sure to perform the onboarding with an OCI user that has admin permissions if you are using an existing OCI account. If you don't have an OCI account, the OracleDB for Azure onboarding process allows you to create a new account during OracleDB for Azure setup. Hence "An OCI tenancy with the necessary admin permissions for the OCI user" is also required.
For Guided Onboarding, the OracleDB for Azure administrative user setting up the service have the "Multicloudlink Administrator" role in the Oracle Database Service (ODS) multitenant application that OracleDB for Azure deploys in the Azure tenancy.
For each subscription being linked, the onboarding user or an Azure administrator must grant the Oracle Database Service multitenant application the following roles:
Contributor
EventGrid Data Sender
Monitoring Metrics Publisher
Network Contributor
Hence "Specific roles for the Oracle Database Service (ODS) enterprise application in Azure" is also required.
When provisioning Oracle Base Database systems or Oracle Exadata Cloud VM clusters, you must have an Azure Virtual Network available to OracleDB for Azure to complete the provisioning oper-ation. However this is NOT required for OracleDB for Azure setup. Hence "A preprovisioned Az-ure Virtual Network (VNet)" is the CORRECT ANSWER.
質問 # 38
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. Remote region
- B. Availability Domains
- 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 # 39
In the context of Oracle FastConnect, what are the two types of virtual circuits?
- A. Layer 3 and Layer 4
- B. Private and Public
- C. Standard and High-Performance
- D. Intra-Region and Inter-Region
正解：B
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 # 40
What is the role of the Oracle Database Service enterprise application in OracleDB for Azure?
- A. It provides a distributed, scalable, shared-nothing, in-memory, hybrid columnar, query processing engine designed for extreme performance.
- B. It creates and manages resources in the Azure subscription, streams OCI Database metrics to Azure App Insights and events to Azure Log Analytics, and configures net-work settings in Azure so that Azure resources can access database resources in OCI.
- C. It allows users to log in to the OCI Console with the same Azure credentials for Azure and the OracleDB for Azure portal.
- D. It allows you to add database compute servers and storage servers to your system at any time after provisioning.
正解：B
解説：
The Oracle Database Service multitenant application can:
Create and manage resources in the subscription (for example, the custom dashboard, Azure App Insights, and Azure Log Analytics workspaces OracleDB for Azure creates for each provisioned database).
Stream OCI Database metrics to Azure App Insights and events to Azure Log Analytics.
Configure network settings in Azure so Azure resources can access the database resources in OCI.
Submit events to Azure Event Grid.
