Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Sample Questions (Q13-Q18):

NEW QUESTION # 13
What is the role of ExpressRoute in the context of Oracle Interconnect for Azure?

A. ExpressRoute is used to manage the routing tables within the OCI VCN for traffic destined to Azure.
B. ExpressRoute is Microsoft Azure's dedicated private connection service, providing the physical connection point for the Interconnect.
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

Answer: B

Explanation:
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

NEW QUESTION # 14
What is the next essential step on the Azure side to establish the connection after creating the FastConnect virtual circuit on the OCI side?

A. Create a Virtual Network Gateway of type "ExpressRoute" and establish a connection to the OCI FastConnect virtual circuit using the service key provided by Oracle.
B. Establish an IPsec VPN tunnel between the Azure VNet and the OCI VCN.
C. Configure a Network Virtual Appliance (NVA) for routing between the two cloud environments.
D. Create an ExpressRoute circuit and configure a private peering.

Answer: A

Explanation:
Here's a breakdown:
OCI Side: You create a FastConnect virtual circuit. Oracle provides you with a service key. This key is crucial for connecting from the Azure side.
Azure Side: You need to create an ExpressRoute Gateway. This is a specific type of Virtual Network Gateway designed for ExpressRoute connections. It's the Azure-side endpoint for the dedicated connection.
Connecting the two: You use the service key provided by Oracle during the ExpressRoute Gateway configuration to link it to the FastConnect virtual circuit. This establishes the physical connection between the two cloud environments.
Why the other options are incorrect:
a) Create an ExpressRoute circuit and configure a private peering. While you do create an ExpressRoute circuit, simply creating it isn't enough to connect to the OCI FastConnect. You need the ExpressRoute Gateway to terminate the connection and the service key to authorize it. The private peering is configured after the connection is established.
b) Establish an IPsec VPN tunnel between the Azure VNet and the OCI VCN. Oracle Interconnect for Azure uses a dedicated, private connection, not a VPN over the public internet.
c) Configure a Network Virtual Appliance (NVA) for routing between the two cloud environments. While NVAs can be used for advanced routing or security functions, they are not required for the basic establishment of the Interconnect. The direct connection through ExpressRoute and FastConnect handles the basic routing.

NEW QUESTION # 15
Which is not a driver for using multiple clouds?

A. Redundancy/Disaster Recovery
B. Content Delivery Network
C. Cost Optimization
D. Best of Breed Cloud Services

Answer: B

Explanation:
Drivers for adopting multicloud architectures typically include redundancy/disaster recovery (ensuring availability across providers), best-of-breed cloud services (leveraging specialized offerings), and cost optimization (balancing expenses across clouds). A Content Delivery Network (CDN) is a specific service for distributing content globally, often provided by cloud vendors, but it is not a strategic driver for adopting a multicloud approach. CDNs can be used within a single cloud or multicloud setup, but they don't inherently motivate the decision to use multiple clouds. Oracle's multicloud strategy documentation highlights the other three as primary motivations.

NEW QUESTION # 16
Why would you federate the Azure tenant's Microsoft Entra ID with an OCI identity domain?

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

Answer: D

Explanation:
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).

NEW QUESTION # 17
A company wants to implement a hybrid cloud strategy using OCI and their on-premises data center. They need to extend their existing Active Directory to OCI for seamless user authentication and authorization. Which service is BEST suited for this scenario?

A. Microsoft Azure Active Directory
B. Oracle Identity Cloud Service (IDCS)
C. Oracle Cloud Infrastructure Identity and Access Management (IAM)
D. OCI Active Directory integration through VPN or FastConnect.

Answer: D

Explanation:
Here's why:
OCI Active Directory integration: This approach allows you to seamlessly integrate your on-premises Active Directory domain controllers with OCI. By establishing a secure connection (either via VPN or, preferably, FastConnect for better performance), you can extend your existing domain to OCI, allowing users to use their existing credentials to access resources in both environments. This maintains a single source of truth for user identities.
Why the other options are less suitable:
A). Oracle Identity Cloud Service (IDCS): IDCS is a cloud-native identity management service. While it can integrate with on-premises Active Directory through synchronization, it creates a separate identity store. This means changes made in one directory need to be synced to the other, introducing potential latency and complexity. It's not a true extension of the existing domain.
B). Oracle Cloud Infrastructure Identity and Access Management (IAM): OCI IAM is the native identity and access management service for OCI. It's used for managing access to OCI resources, but it's not designed for directly extending an on-premises Active Directory. While it can federate with other identity providers, direct integration with on-premises AD is best achieved through the method in option D.
C). Microsoft Azure Active Directory: Azure AD is Microsoft's cloud-based identity and access management service. It's not directly related to extending an on-premises Active Directory to OCI. While you could potentially implement complex cross-cloud federation, it would be far more complex and less efficient than directly extending the existing AD to OCI.
