Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Sample Questions (Q48-Q53):

NEW QUESTION # 48
What is the primary purpose of a Local Peering Gateway (LPG) in OCI?

A. To connect VCNs in different regions.
B. To establish a connection between two VCNs within the same region.
C. To provide internet connectivity for instances within a VCN.
D. To connect a VCN to an on-premises network via FastConnect.

Answer: B

Explanation:
Here's a breakdown:
VCN Peering within a Region: An LPG enables you to create a peering connection between two Virtual Cloud Networks (VCNs) that reside in the same OCI region. This allows resources in one VCN to communicate directly with resources in the other VCN using private IP addresses, without traversing the public internet.
Private Communication: Communication between peered VCNs via LPGs is private and secure, as it stays within the OCI network fabric.
Simplified Networking: LPGs simplify network configuration compared to other connectivity options when you need to connect VCNs within the same region.
Why the other options are incorrect:
A). To connect a VCN to an on-premises network via FastConnect: Connecting to on-premises networks is the function of a Dynamic Routing Gateway (DRG), used in conjunction with FastConnect or VPN Connect.
C). To provide internet connectivity for instances within a VCN: Internet connectivity is provided by an Internet Gateway, not an LPG.
D). To connect VCNs in different regions: Connecting VCNs in different regions requires a DRG and Remote Peering Connections (RPCs), not LPGs.

NEW QUESTION # 49
Regarding the benefits of multicloud, which of the following statements is NOT accurate?

A. A major advantage of Multicloud is to simplify the management of the different services into a single pane of glass.
B. Multicloud allows organizations to utilize specialized, best-of-breed services available from different vendors.
C. By distributing workloads across multiple providers, multicloud improves overall resilience and reduces the impact of localized failures.
D. Multicloud enables businesses to avoid vendor lock-in, providing greater flexibility in choosing services.

Answer: A

Explanation:
In reality, managing a multicloud environment is often more complex than managing a single-cloud environment. Each cloud provider has its own management tools, APIs, and interfaces. Integrating these into a true "single pane of glass" is a significant challenge, although there are emerging tools and platforms attempting to address this. It's not a simplification; it's an added layer of complexity.
The other statements are accurate:
a) Multicloud enables businesses to avoid vendor lock-in, providing greater flexibility in choosing services: This is a key driver for multicloud adoption.
b) Multicloud allows organizations to utilize specialized, best-of-breed services available from different vendors: Different cloud providers excel in different areas, and multicloud allows organizations to take advantage of these specializations.
d) By distributing workloads across multiple providers, multicloud improves overall resilience and reduces the impact of localized failures: This is a core benefit of multicloud for disaster recovery and business continuity.

NEW QUESTION # 50
To minimize the cost of your Autonomous Database while ensuring it scales automatically to handle peak loads. Which configuration is MOST suitable?

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

Answer: C

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.

NEW QUESTION # 51
Which type of traffic is NOT supported by the cross-cloud connection between Oracle Cloud Infrastructure (OCI) and Microsoft Azure?

A. Traffic between an Azure VNet and OCI VCN using private IP addresses
B. Traffic from an Azure VNet to a peered OCI VCN within the same OCI region
C. Traffic from an Azure Virtual Network (VNet) to a peered OCI Virtual Cloud Network (VCN) in a different OCI region
D. Traffic between your on-premises network and the OCI VCN through the Azure VNet

Answer: D

Explanation:
The cross-cloud interconnection between OCI and Azure, facilitated by FastConnect and ExpressRoute, establishes a direct, private connection between the two cloud environments. It does not extend to transitive routing from on-premises networks through Azure to OCI.
Here's a breakdown:
A). Traffic from an Azure Virtual Network (VNet) to a peered OCI Virtual Cloud Network (VCN) in a different OCI region: This is supported. The interconnection allows traffic to flow between VNets and VCNs, even across different regions within each cloud.
B). Traffic between an Azure VNet and OCI VCN using private IP addresses: This is the core functionality of the interconnection. It enables communication using private IP addresses, ensuring secure and private communication between the two clouds.
C). Traffic from an Azure VNet to a peered OCI VCN within the same OCI region: This is also supported. The connection works regardless of whether the VCNs are in the same or different OCI regions.
D). Traffic between your on-premises network and the OCI VCN through the Azure VNet: This is not supported. The interconnection is designed for direct connectivity between Azure and OCI. It doesn't act as a transit point for on-premises traffic to reach OCI. To connect your on-premises network to OCI, you would need a separate connection, such as an OCI FastConnect or a VPN connection directly to OCI. Similarly, to connect your on-premises network to Azure, you would need an Azure ExpressRoute or a VPN connection to Azure

NEW QUESTION # 52
Which interface can you use to provision Oracle Database at Azure Exadata Infrastructure?

A. OCI console
B. OCI Terraform scripts
C. Azure Terraform scripts
D. Azure portal and APIs

Answer: D

Explanation:
Since Oracle Database@Azure places the Exadata infrastructure within Azure datacenters, the primary interface for provisioning and managing that infrastructure is through Azure's own tools. This includes:
Azure portal: This is the graphical user interface for managing Azure resources. You can use the portal to deploy and configure the Exadata infrastructure.
Azure APIs: Azure also provides a rich set of APIs that allow for programmatic management of resources. These APIs can be used to automate the provisioning and configuration of Exadata infrastructure.
Here's why the other options are incorrect:
a). OCI console: The OCI console is used for managing resources within Oracle Cloud Infrastructure. Since the Exadata infrastructure in Oracle Database@Azure resides within Azure, the OCI console is not used for its provisioning.
b). Azure Terraform scripts: While Terraform can be used to manage Azure resources, it's not the only or primary interface. The Azure portal and APIs are the core tools provided by Microsoft. Terraform would be used as a layer on top of those.
d). OCI Terraform scripts: OCI Terraform scripts are for managing resources in Oracle Cloud Infrastructure. They are not relevant for managing Exadata infrastructure within Azure.
