質問 # 24
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. Use public internet connections to transfer data between Azure and OCI, encrypting the data in transit.
- B. Establish a dedicated, private connection between Azure and OCI using Azure Ex-pressRoute and Oracle FastConnect.
- C. Implement a hybrid cloud approach by integrating on-premises infrastructure with both Azure and OCI.
- D. Leverage a VPN Gateway to create an encrypted tunnel between Azure and OCI for secure data transfer.
正解：B
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.

- C. By providing more storage and computing resources than any other cloud service pro-vider
- D. By allowing customers to manually create cross-cloud deployments using the Intercon-nect
正解：B
解説：
Oracle Database Service for Azure (OracleDB for Azure) is an Oracle managed service delivering Oracle Database services in Oracle Cloud Infrastructure (OCI) directly to Microsoft Azure custom-ers through the OCI Azure Interconnect (a capability available between the two cloud environments in regions located around the world).
OracleDB for Azure uses a service-based approach, and is an alternative to manually creating complex cross-cloud deployments using the Interconnect.
質問 # 26
How does Oracle Database Service for Azure enable bidirectional communication between applica-tions in the Azure tenancy and database resources in OracleDB for Azure?
- A. By federating the Azure tenant's Azure Active Directory (AAD) with an OCI identity domain
- B. By creating a custom Azure dashboard for each database
- C. By granting the Oracle Database Service enterprise application specific roles in Azure
- D. By configuring DNS on both sides of the Interconnect
正解：D
解説：
With OCI multicloud's OracleDB for Azure, your database resources reside in an OCI account that is linked to your Azure account through Oracle Interconnect for Microsoft Azure, an Oracle-managed tunnel connection.
OracleDB for Azure configures DNS on both sides of the Interconnect to enable bi-directional communication between applications in the Azure tenancy and database resources in OracleDB for Azure.
質問 # 27
What is the purpose of using Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) policies in a cross-cloud connection between Microsoft Azure and OCI?
- A. To control the bandwidth of the connection between the Azure VNet and the OCI VCN
- B. To control the location of the cross-cloud connection
- C. To control the type of traffic allowed between the Azure VNet and the OCI VCN
- D. To control who can manage OCI route tables, network security groups, and security lists
正解：D
解説：
Controlling the Establishment of a Connection
With Oracle Cloud Infrastructure IAM policies, you can control:
Who in your organization has the authority to create a FastConnect virtual circuit.
Who can manage route tables, network security groups, and security lists.
Oracle and Microsoft have created a cross-cloud connection between Oracle Cloud Infrastructure and Microsoft Azure in certain regions. So, the option "To control the location of the cross-cloud connection" has nothing to do with IAM policies and hence is INCORRECT.
The option "To control the type of traffic allowed between the Azure VNet and the OCI VCN" is also INCORRECT as you use Security Lists/Network Security Group to filter traffic and not IAM policies.
IAM policies also have no role to play in determining the bandwidth of the connection.
質問 # 28
Which is true regarding fully automated and guided onboarding for the OracleDB for Azure ser-vice?
- A. Fully automated onboarding requires more permissions to be granted than guided onboarding.
- B. Guided onboarding is simpler and faster than fully automated onboarding.
- C. An Azure user who completes fully automated onboarding can log in to the OracleDB for Azure portal, but cannot deploy and provision databases.
- D. An Azure user who completes guided onboarding cannot log in to the OracleDB for Azure portal.
正解：A
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 # 29
Which database system is NOT available in Oracle Database Service for Azure?
- A. Autonomous Database on shared Exadata infrastructure
- B. Oracle Exadata Database
- C. Base Database using Oracle Enterprise Edition or Oracle Standard Edition 2 databases
- D. Autonomous Database on dedicated Exadata infrastructure
正解：D
解説：
Oracle Database Service for Azure offers the following products:
Oracle Exadata Database: You can provision flexible Exadata systems that allow you to add database compute servers and storage servers to your system at any time after provision-ing.
Autonomous Database on shared Exadata infrastructure: Autonomous Database pro-vides an easy-to-use, fully autonomous database that scales elastically, delivers fast query performance, and requires no database administration.
Base Database: Using OracleDB for Azure, you can deploy Oracle Enterprise Edition or Oracle Standard Edition 2 databases on virtual machine DB systems. You can deploy single-node systems or 2-node RAC systems.
MySQL Database with HeatWave: MySQL Database Service is a fully managed Oracle Cloud native service available through OracleDB for Azure. It is developed, managed, and supported by the MySQL team in Oracle. Optionally, you can add a HeatWave cluster to a MySQL DB system. HeatWave is a distributed, scalable, shared-nothing, in-memory, hybrid columnar, query processing engine designed for extreme performance.
Hence, "Autonomous Database on dedicated Exadata infrastructure" is NOT available and hence the CORRECT ANSWER.
質問 # 30
Which is NOT an Azure resource that is created when you provision a database using Oracle Data-base Service for Azure?
- A. Log Analytics workspace
- B. Custom Dashboard workspace
- C. Application Insights workspace
- D. Oracle Database Service
正解：D
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 # 31
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 deployment of a single cloud service across multiple regions and data centers for better performance
- C. The use of multiple cloud services from a single provider for redundancy and high availability
- D. The integration of on-premises infrastructure with cloud services for a hybrid cloud approach
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 # 32

- A. To offer a serverless MySQL deployment
- B. To ensure high availability and fault tolerance
- C. To provide a distributed in-memory query accelerator
- D. To enable seamless database migration from on-premises to OCI
正解：C
解説：
HeatWave is an in-memory query accelerator developed for Oracle MySQL Database Service. It's a massively parallel, hybrid, columnar, query-processing engine with state-of-art algorithms for distributed query processing which provide very high performance for queries.
質問 # 33
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 VPN Gateway to create an encrypted tunnel to Object Storage.
- B. Use a Service Gateway to establish a secure connection to Object Storage.
- C. Use a Local Peering Gateway to peer with the Object Storage subnet.
- D. Use a NAT Gateway to enable private access to Object Storage.
正解：B
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 # 34
Which step is NOT valid while implementing an OCI-Azure Interconnect?
- A. Create a Dynamic Routing Gateway and attach it to the OCI VCN.
- B. Select FastConnect Direct as the connection type.
- C. Set up an Oracle FastConnect virtual circuit.
- D. Set up an Azure ExpressRoute circuit.
正解：B
解説：
As you can see in the below screenshot (from the OCI Console), while implementing OCI-Azure Interconnect you need to select Connection type: FastConnect partner and select Microsoft Azure ExpressRoute as the Partner.
Hence, "Select FastConnect Direct as the connection type" is NOT VALID and hence the correct answer.
質問 # 35
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. Allow all traffic from the Azure VNet without restrictions.
- C. Limit all inbound and outbound traffic from the Azure VNet to expected and well-defined traffic.
- D. Remove all OCI security rules.
正解：C
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 # 36
A consulting company that employs Oracle Cloud Infrastructure (OCI) architects has successfully completed resource migration from Microsoft Azure to OCI, and no longer requires the Oracle FastConnect circuit to Azure. The project manager has asked you to delete all resources involved in this cross-cloud connectivity. From the Azure side, you delete the Resource Group. After a while, you notice that all Azure resources have been deleted, except for the Azure ExpressRoute circuit.
What could be a potential reason for this issue?
- A. You need to remove all routes that point to the cross-cloud connection on both OCI and Azure before you can delete the circuit.
- B. Your bill from the OCI side needs to be paid in full before you can remove the Azure ExpressRoute circuit.
- C. You need to first delete the Oracle FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit.
- D. You need to remove the Azure ExpressRoute Partner Service Key from the Oracle FastConnect circuit, and then you can delete the ExpressRoute virtual circuit.
正解：C
解説：
To delete the interconnect, perform these steps in the order given. Failure to do so results in a failed state ExpressRoute circuit.
1. Delete the ExpressRoute connection. Delete the connection by selecting the Delete icon on the page for your connection.
2. Delete the Oracle FastConnect circuit from the Oracle Cloud Console.
3. Once the Oracle FastConnect circuit has been deleted, you can delete the Azure Ex-pressRoute circuit.
Hence "You need to first delete the Oracle FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit." is the CORRECT AN-SWER.
