Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Sample Questions (Q50-Q55):

NEW QUESTION # 50
How can an organization ensure secure and efficient data transfer between their frontend data analytics applications in Microsoft Azure and the backend Oracle Autonomous Data Warehouse in Oracle Cloud Infrastructure (OCI) in a multicloud solution?

A. By using public internet connections to transfer data between Azure and OCI, encrypting the data in transit
B. By implementing a hybrid cloud approach that integrates on-premises infrastructure with both Azure and OCI
C. By leveraging a VPN Gateway to create an encrypted tunnel between Azure and OCI for secure data transfer
D. By establishing a dedicated, private connection between Azure and OCI using Azure ExpressRoute and Oracle FastConnect

Answer: D

Explanation:
Here's why:
Azure ExpressRoute and Oracle FastConnect: This combination provides a direct, private connection between the two cloud environments. This offers several advantages:
High bandwidth: Enables fast data transfer, crucial for analytics workloads.
Low latency: Minimizes delays in data transfer, improving application performance.
Enhanced security: Data travels over a private connection, reducing exposure to the public internet.
Reliability: Dedicated connections offer more consistent performance compared to internet-based connections.
Why the other options are less suitable:
a). By leveraging a VPN Gateway to create an encrypted tunnel between Azure and OCI for secure data transfer: While VPNs provide secure connections, they generally offer lower bandwidth and higher latency compared to dedicated connections like ExpressRoute and FastConnect. This can be a bottleneck for data-intensive analytics applications.
b). By using public internet connections to transfer data between Azure and OCI, encrypting the data in transit: While encryption protects the data during transit, using the public internet introduces variability in performance (bandwidth and latency) and potential security risks compared to a private connection. This is not suitable for production analytics workloads that require consistent and reliable performance.
c). By implementing a hybrid cloud approach that integrates on-premises infrastructure with both Azure and OCI: Introducing on-premises infrastructure adds complexity and doesn't directly address the need for efficient data transfer between Azure and OCI. While a hybrid approach might be part of a broader strategy, it's not the primary solution for this specific scenario.

NEW QUESTION # 51
How are resources provisioned in Oracle Database@Azure service?

A. Oracle Exadata Infrastructure, Oracle Exadata VM Cluster, Oracle container, and pluggable databases are provisioned in the Azure portal.
B. Oracle Exadata VM Cluster and Oracle container databases are provisioned in the OCI console.
C. Oracle Exadata Infrastructure and Oracle Exadata VM Cluster are provisioned in the Azure portal.
D. Oracle Exadata Infrastructure and Oracle Exadata VM Cluster are provisioned in the OCI console and Oracle container and pluggable databases in the Azure portal.

Answer: C

Explanation:
Oracle Database@Azure allows customers to provision and manage Oracle database resources directly within the Azure portal, streamlining multicloud operations. Specifically, the Oracle Exadata Infrastructure and Exadata VM Cluster are provisioned through Azure, integrating OCI database capabilities into the Azure ecosystem. Options involving the OCI console (B and C) are incorrect because this service is designed for Azure-native management. Option D overextends by including container and pluggable databases, which are managed post-provisioning, not part of the initial infrastructure setup in Azure. This is detailed in the Oracle Database@Azure service documentation.

NEW QUESTION # 52
What is the first action that needs to be completed during the onboarding of Oracle Database@Azure?

A. Linking the OCI account is recommended (but optional) during onboarding to avoid logging in to the OCI account by manually providing credentials each time.
B. The onboarding step is preceded by a private offer purchase from the Oracle Private Offer marketplace.
C. The customer consults Oracle Sales for a price agreement, which is then created as a Private Offer in the Azure marketplace by Oracle to be purchased by the customer.
D. An active Azure subscription is linked with the OCI tenancy for billing purposes.

Answer: C

Explanation:
The initial step in onboarding Oracle Database@Azure is establishing a commercial agreement. This involves:
Contacting Oracle Sales: The customer first engages with Oracle Sales to discuss their requirements and negotiate pricing.
Private Offer Creation: Based on the agreed-upon terms, Oracle creates a Private Offer within the Azure Marketplace. This private offer is specifically tailored to the customer's needs and pricing.
Private Offer Purchase: The customer then purchases this private offer through the Azure Marketplace, formally establishing the commercial relationship for using Oracle Database@Azure.
This process ensures that the customer has a clear understanding of the costs and terms associated with the service before proceeding with any technical setup.
Why the other options are incorrect:
a). Linking the OCI account is recommended (but optional) during onboarding to avoid logging in to the OCI account by manually providing credentials each time: Linking an OCI account is beneficial for certain management tasks and integration, but it's not the first step in the onboarding process. The commercial agreement must be in place first.
b). An active Azure subscription is linked with the OCI tenancy for billing purposes: While billing is eventually handled through Azure, the initial step is establishing the commercial agreement through the private offer. The linking of subscriptions happens later in the process.
d). The onboarding step is preceded by a private offer purchase from the Oracle Private Offer marketplace: While the purchase is necessary, it's preceded by the consultation with Oracle Sales and the creation of the private offer itself

NEW QUESTION # 53
Which of the following is NOT a factor influencing the bandwidth options available for your connection?

A. The subnet size in your Azure Virtual Network
B. The availability of interconnect partners in the region
C. The location of your Azure region
D. The location of your OCI region

Answer: A

Explanation:
Here's why:
When considering bandwidth for a connection between Azure and OCI (typically using Azure ExpressRoute and OCI FastConnect), the focus is on the dedicated connections themselves, not the internal subnetting within your virtual networks.
Bandwidth is determined by the ExpressRoute circuit and FastConnect virtual circuit: You select specific bandwidth tiers when you provision your ExpressRoute circuit in Azure and your FastConnect virtual circuit in OCI. These tiers define the maximum bandwidth available for the connection.
Subnetting is internal to each cloud: The size of your subnets within your Azure Virtual Network (VNet) or your OCI Virtual Cloud Network (VCN) affects how you organize your resources within each cloud, but it does not directly impact the bandwidth of the interconnect between the clouds.
Why the other options are factors:
A). The location of your Azure region: The available bandwidth options for ExpressRoute can sometimes vary slightly depending on the specific Azure region.
B). The location of your OCI region: Similarly, the available bandwidth options for FastConnect can vary based on the OCI region.
D). The availability of interconnect partners in the region: The availability of interconnect partners (the companies that provide the physical connectivity between Azure and OCI) in a given region can influence the available bandwidth options and the process of establishing the connection.

NEW QUESTION # 54
To minimize the cost of your Autonomous Database while ensuring it scales automatically to handle peak loads. Which configuration is MOST suitable?

A. Base Database on bare metal with manual scaling.
B. Autonomous Database on Shared Infrastructure with auto-scaling enabled.
C. Autonomous Database on Dedicated Infrastructure with manual scaling.
D. Base Database on a virtual machine with auto-scaling configured.

Answer: B

Explanation:
Here's why:
Shared Infrastructure: Using shared infrastructure is inherently more cost-effective than dedicated infrastructure. You share the underlying hardware resources with other users, which reduces your costs significantly.
Auto-scaling: Enabling auto-scaling allows the Autonomous Database to automatically adjust its compute and storage resources based on workload demands. This means you only pay for the resources you actually consume. During peak loads, the database scales up to handle the increased demand, and during periods of low activity, it scales down to minimize costs.
Why other options are less suitable:
a) Autonomous Database on Dedicated Infrastructure with manual scaling: Dedicated infrastructure is the most expensive option. Manual scaling requires manual intervention to adjust resources, which is not ideal for handling unpredictable peak loads and does not minimize cost automatically.
c) Base Database on a virtual machine with auto-scaling configured: While this offers some flexibility, it requires significantly more management overhead compared to Autonomous Database. You are responsible for managing the operating system, database software, backups, and other administrative tasks. Autonomous Database handles all of this for you.
d) Base Database on bare metal with manual scaling: Bare metal is the most expensive and least flexible option. Manual scaling makes it unsuitable for handling peak loads efficiently and cost-effectively.
