Use the OCI-Azure Interconnect to establish a private, high-bandwidth, low-latency connection between the two clouds.

Use the public internet to connect the two clouds.

Use a VPN connection to connect the two clouds.

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.

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.

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.

QUESTION 38
How do you ensure that traffic between your OCI VCN and Azure Virtual Network uses the interconnect and not the public internet?

Configure security lists in both OCI and Azure to block traffic over the internet.

Configure route tables in both OCI and Azure to prioritize routes through the interconnect.

Disable public IP addresses on instances in both environments.

Enable private peering between the VCN and the Virtual Network.

Here’s why:
Route tables are the core mechanism for controlling network traffic flow within both OCI and Azure. To ensure traffic uses the interconnect (like FastConnect/ExpressRoute), you need to configure the route tables to direct traffic destined for the other cloud provider’s address space through the interconnect.
OCI Route Tables: In OCI, you’d create a route rule in your VCN’s route table that directs traffic destined for the Azure Virtual Network’s address space (e.g., a specific CIDR block) to the Dynamic Routing Gateway (DRG) that is connected to your FastConnect circuit.
Azure Route Tables: In Azure, you’d configure a route in your Virtual Network’s route table that directs traffic destined for the OCI VCN’s address space to the ExpressRoute gateway.
By configuring these routes, you explicitly tell the networks to use the private, dedicated connection for communication between the two clouds.
Why the other options are not sufficient or correct:
A). Configure security lists in both OCI and Azure to block traffic over the internet: Security lists (or Network Security Groups in Azure) control access based on ports and protocols, but they don’t control routing. Blocking internet traffic would prevent instances from accessing the internet, but it wouldn’t force traffic to use the interconnect. The routing decision happens before the security list rules are evaluated.
C). Disable public IP addresses on instances in both environments: Disabling public IPs prevents direct internet access to the instances, but it doesn’t guarantee that traffic will use the interconnect. Without proper routing, the instances wouldn’t be able to communicate with each other at all.
D). Enable private peering between the VCN and the Virtual Network: “Private peering” is a general term and doesn’t fully describe the required configuration. While the interconnect is a form of private peering, it’s the route table configuration that actually directs traffic over that private connection. Simply enabling the interconnect isn’t enough; you must configure the routing.

QUESTION 39
What types of metrics can be monitored for Oracle databases using Azure services in Oracle Database@Azure?

Node status, ASM diskgroup utilization, and file system utilization

Invoice payments, storage usage reports, and support rewards

Block changes, OCPU utilization, and database wait time

Automatic backup configuration and database PSU updates

QUESTION 40
Which task is the customer responsible for when using Oracle Database on Google Cloud?

Provision containers and pluggable databases in the Google Cloud Console

Update infrastructure and software in OCI

Provision Exadata VM cluster in OCI

Provision Exadata Infrastructure through the Google Cloud Console

QUESTION 41
What is the role of a Dynamic Routing Gateway (DRG) in an OCI VCN?

To provide internet connectivity for instances within the VCN.

To establish secure connections between VCNs in the same region.

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.

To provide access to Oracle services, such as Object Storage, without traversing the public internet.

QUESTION 42
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?

By leveraging a VPN Gateway to create an encrypted tunnel between Azure and OCI for secure data transfer

By using public internet connections to transfer data between Azure and OCI, encrypting the data in transit

By implementing a hybrid cloud approach that integrates on-premises infrastructure with both Azure and OCI

By establishing a dedicated, private connection between Azure and OCI using Azure ExpressRoute and Oracle FastConnect
