Oracle Cloud Infrastructure 2025 Multicloud Architect Professional 認定 1Z0-1151-25 試験問題 (Q24-Q29):

質問 # 24
Which statement accurately describes the difference between public peering and private peering in OCI FastConnect?

A. Public peering is used to connect on-premises networks to private OCI resources, while private peering is used to connect to Oracle public-facing services such as Object Storage.
B. Public peering and private peering cannot be configured simultaneously in a single OCI FastConnect setup.
C. Both public and private peering require the use of the Oracle Services Network to connect to Oracle Cloud resources.
D. Private peering allows direct access to resources within a Virtual Cloud Network (VCN) using private IP addresses, while public peering provides access to Oracle public-facing services, bypassing the Internet.

正解：D

解説：
Private peering in OCI FastConnect connects on-premises networks to a VCN using private IPs, while public peering connects to Oracle's public services (e.g., Object Storage) via public IPs, avoiding the internet. Option A is false-they can coexist. Option B misstates the network usage, and Option D reverses the definitions. Oracle's FastConnect documentation clearly defines these roles.

質問 # 25
What comprises the physical architecture of Oracle Database@Azure for ABC Private Limited?

A. Oracle places three of the Oracle Cloud Infrastructure (OCI) availability domains, one in each of the three Azure availability zones.
B. OCI pods in the Azure data center contain the Exadata Database Service stack, but all other dependencies and controls reside in the nearest OCI data center.
C. Oracle creates an OCI pod closest to the Azure Data Center and connects it with the nearest OCI region via a low-latency Oracle-managed network link.
D. OCI pods created inside the Azure data center are an extension of the OCI data center, with the same OCI infrastructure and service stack, including the Exadata Database Service, along with all dependencies.

正解：D

解説：
Oracle Database@Azure involves deploying dedicated OCI hardware within Azure data centers. These deployments are referred to as "OCI pods." These pods are not simply connected to OCI; they are essentially an extension of the OCI environment, residing physically within the Azure footprint.
Here's why the other options are incorrect:
A). Oracle places three of the Oracle Cloud Infrastructure (OCI) availability domains, one in each of the three Azure availability zones: Availability Domains (ADs) are OCI's high-availability construct. Placing entire ADs within Azure Availability Zones is not how the integration works. The OCI pods are more granular deployments.
B). Oracle creates an OCI pod closest to the Azure Data Center and connects it with the nearest OCI region via a low-latency Oracle-managed network link: While there's a connection to OCI for management and certain services, the key is that the core infrastructure for Oracle Database@Azure resides within the Azure data center, not connected to a geographically separate OCI region for the core database operations.
C). OCI pods in the Azure data center contain the Exadata Database Service stack, but all other dependencies and controls reside in the nearest OCI data center: This is partially true in that some control plane functions might interact with OCI, but the core database service, including Exadata (if used), runs directly within the OCI pod in the Azure data center.

質問 # 26
What is the role of a Dynamic Routing Gateway (DRG) in an OCI VCN?

A. To provide internet connectivity for instances within the VCN.
B. To establish secure connections between VCNs in the same region.
C. To connect the VCN to networks outside of OCI, such as on-premises networks via FastConnect or VPN Connect, or to other VCNs in different regions.
D. To provide access to Oracle services, such as Object Storage, without traversing the public internet.

正解：C

解説：
C). To connect the VCN to networks outside of OCI, such as on-premises networks via FastConnect or VPN Connect, or to other VCNs in different regions.
Here's a breakdown of the role of a Dynamic Routing Gateway (DRG) in OCI:
Connectivity to External Networks: The primary function of a DRG is to provide connectivity between your VCN and networks outside of OCI. This includes:
On-premises networks: You can establish a private connection between your on-premises data center and your OCI VCN using FastConnect (dedicated private line) or VPN Connect (IPSec VPN). The DRG acts as the termination point for these connections on the OCI side.
Other VCNs (in different regions or tenancies): You can use a DRG to create connections between VCNs in different OCI regions or even in different OCI tenancies. This enables you to build complex multi-region or multi-tenant network architectures.
Why other options are incorrect:
A). To provide internet connectivity for instances within the VCN: Internet connectivity is provided by an Internet Gateway, not a DRG.
B). To establish secure connections between VCNs in the same region: While a DRG can be used for connections between VCNs in the same region, it's not its primary purpose. Local VCN peering is generally used for this scenario as it offers lower latency and is simpler to configure.
D). To provide access to Oracle services, such as Object Storage, without traversing the public internet: Access to Oracle services without traversing the public internet is provided by a Service Gateway, not a DRG.

質問 # 27
Why would you federate the Azure tenant's Microsoft Entra ID with an OCI identity domain?

A. To enable Azure users to log in to the OCI Console using their Azure credentials
B. To enable two-way communication between Azure and OCI
C. To define an Azure Virtual Network (VNet) during provisioning
D. To manage and create resources in the subscription

正解：A

解説：
Federating Microsoft Entra ID (Azure's identity service) with an OCI identity domain allows users managed in Azure to access OCI resources without needing separate OCI credentials. This is a key aspect of single sign-on (SSO).
Here's a breakdown:
Federation and SSO: By establishing a trust relationship between Microsoft Entra ID and OCI, users who have already authenticated to Azure can seamlessly access OCI resources. When an Azure user tries to access the OCI Console, they are redirected to Azure for authentication. After successful authentication in Azure, they are redirected back to OCI with a security token, granting them access.
Why the other options are incorrect:
a). To define an Azure Virtual Network (VNet) during provisioning: Defining Azure VNet is related to networking configuration in Azure, not identity federation between Azure and OCI.
b). To enable two-way communication between Azure and OCI: While interconnect solutions like Oracle Interconnect for Microsoft Azure enable network connectivity between the two clouds, identity federation is specifically about user authentication and authorization, not general network communication.
c). To manage and create resources in the subscription: While federation allows authorized users to manage OCI resources, the primary purpose is about authentication (verifying user identity) rather than general resource management. OCI's Identity and Access Management (IAM) service handles authorization (controlling what actions users can perform).

質問 # 28
What is the role of BGP dynamic routing in the connection between an Azure VNet and OCI VCN?

A. It is used to create a static routing configuration for the VNet and VCN.
B. It is used to establish a direct connection between the VNet and VCN without a virtual circuit.
C. It is used to automatically select the best route between the VNet and VCN.
D. It is used to manage the security rules for the VNet and VCN.

正解：C

解説：
Border Gateway Protocol (BGP) is a dynamic routing protocol used in the OCI-Azure Interconnect to automatically determine the optimal path for data between an Azure Virtual Network (VNet) and an OCI Virtual Cloud Network (VCN). Unlike static routing (Option A), BGP adapts to network changes, ensuring efficient and reliable connectivity. It doesn't establish the connection itself (Option B) or manage security rules (Option C)-those are handled by FastConnect/ExpressRoute and security lists, respectively. Oracle's networking documentation for multicloud interconnects confirms BGP's role in route optimization.
