Oracle Cloud Infrastructure 2025 Multicloud Architect Professional 認定 1Z0-1151-25 試験問題 (Q41-Q46):

質問 # 41
what is the primary purpose of the "cross-connect" established between the OCI and Azure environments?

A. To establish a secure VPN connection for administrative access to the Exadata systems.
B. To facilitate the initial deployment and configuration of the Exadata infrastructure.
C. To provide direct access to Azure storage services from the Exadata systems.
D. To enable high-bandwidth, low-latency communication between the Exadata systems and Azure Virtual Networks.

正解：D

解説：
The "cross-connect" between OCI and Azure, facilitated by Oracle FastConnect and Azure ExpressRoute, is specifically designed to create a direct, private, and high-performance network connection. This connection is crucial for:
High Bandwidth: Enables rapid data transfer between applications running in Azure and the Exadata databases in OCI.
Low Latency: Minimizes delays in communication, which is essential for performance-sensitive applications.
This direct interconnect avoids traversing the public internet, ensuring better performance, security, and reliability for workloads that span both cloud environments

質問 # 42
A company XYZ has been using Oracle Cloud Infrastructure to host their mission-critical applications, but they have decided to start using Azure for some of their workloads. They want to enable connectivity between their Oracle Cloud Infrastructure and Microsoft Azure to create a multicloud architecture.

A. Use a VPN connection to connect the two clouds.
B. None of the above.
C. Use public Internet to connect the two clouds.
D. Use OCI-Azure Interconnect to establish a private, high-bandwidth, low-latency connection between the two clouds.

正解：D

解説：
The OCI-Azure Interconnect is the official Oracle-Microsoft partnership solution for establishing a private, high-bandwidth, and low-latency connection between OCI and Azure. This interconnect leverages Azure ExpressRoute and Oracle FastConnect to create a dedicated network link, bypassing the public internet for enhanced security and performance. A VPN connection (Option A) is possible but less optimal due to higher latency and lower reliability compared to the interconnect. Using the public internet (Option B) is insecure and unsuitable for mission-critical applications. This solution is detailed in Oracle's multicloud architecture guides and the OCI-Azure partnership documentation, emphasizing its suitability for enterprise multicloud deployments.

質問 # 43
What is the function of a NAT Gateway in an OCI VCN?

A. To allow instances in private subnets to initiate outbound connections to the internet without having public IP addresses.
B. To balance network traffic across multiple instances in a subnet.
C. To provide a secure tunnel for connecting to on-premises networks.
D. To provide DNS resolution for instances within the VCN.

正解：A

解説：
Here's a breakdown of the function of a NAT Gateway in OCI:
Outbound Internet Access for Private Subnets: The primary purpose of a NAT Gateway is to enable instances in private subnets (subnets without direct internet access) to initiate outbound connections to the internet. This is crucial for tasks like downloading software updates, accessing external APIs, or connecting to other internet-based services.
No Public IP Required: Instances in private subnets using a NAT Gateway do not need to have public IP addresses assigned to them. This enhances security by preventing direct inbound connections from the internet to these instances.
NAT Functionality: The NAT Gateway performs Network Address Translation (NAT), which translates the private IP addresses of the instances to a public IP address owned by the NAT Gateway when they initiate outbound connections. When the responses come back from the internet, the NAT Gateway translates the destination IP address back to the private IP address of the originating instance.
Why the other options are incorrect:
A). To provide a secure tunnel for connecting to on-premises networks: Secure tunnels to on-premises networks are provided by VPN Connect or FastConnect, not a NAT Gateway.
C). To balance network traffic across multiple instances in a subnet: Network traffic load balancing is handled by Load Balancers, not a NAT Gateway.
D). To provide DNS resolution for instances within the VCN: DNS resolution is provided by a DNS Resolver within the VCN, not a NAT Gateway.

質問 # 44
What is the role of ExpressRoute in the context of Oracle Interconnect for Azure?

A. ExpressRoute is Microsoft Azure's dedicated private connection service, providing the physical connection point for the Interconnect.
B. ExpressRoute is used to manage the routing tables within the OCI VCN for traffic destined to Azure.
C. ExpressRoute is used to encrypt the traffic between OCI and Azure.
D. ExpressRoute provides a backup connection in case the primary Interconnect link fails

正解：A

解説：
Here's a breakdown:
ExpressRoute is Microsoft's service that lets you create private connections between Azure datacenters and infrastructure on your premises or in a colocation environment. In the context of Oracle Interconnect for Azure, ExpressRoute provides the Azure-side of the dedicated connection between the two clouds.
Why other options are incorrect:
A). ExpressRoute is used to encrypt the traffic between OCI and Azure. While ExpressRoute provides a private connection, it doesn't inherently encrypt the traffic. Encryption can be implemented at higher layers (e.g., using VPNs or application-level encryption) if needed.
C). ExpressRoute is used to manage the routing tables within the OCI VCN for traffic destined to Azure. Routing within the OCI VCN is managed by OCI's networking components, primarily the Dynamic Routing Gateway (DRG). ExpressRoute handles routing on the Azure side.
D). ExpressRoute provides a backup connection in case the primary Interconnect link fails. While redundancy can be designed into the Interconnect architecture, ExpressRoute itself is the primary connection method on the Azure side, not a backup

質問 # 45
Which is a database service that CANNOT be provisioned in the Oracle Public Cloud?

A. Autonomous Database on Dedicated Infrastructure
B. Autonomous Database on Shared Infrastructure
C. Exadata Database Service on Dedicated Infrastructure
D. Exadata Database Service on Shared Infrastructure

正解：C

解説：
The "Oracle Public Cloud" typically refers to OCI's broadly accessible cloud services. Autonomous Database on Shared (Option A) and Dedicated Infrastructure (Option B) are available in OCI. However, Exadata Database Service on Dedicated Infrastructure (Option C) is not a standard offering in the public OCI context-it's tied to specific deployments like Database@Azure or on-premises Exadata, not the public cloud. Option D is fictitious. Oracle's documentation clarifies Exadata's dedicated nature outside standard public offerings.
