38. Frage
What is the recommended approach if the application needs to connect to an Autonomous Database from an on-premises environment and you want to establish a secure and dedicated connection?
- A. Use an IPSec VPN tunnel between your on-premises network and your OCI VCN.
- B. Connect directly using the public IP address of the Autonomous Database.
- C. Use FastConnect to establish a dedicated connection between your on-premises network and your OCI VCN.
- D. Configure a reverse proxy server in your OCI VCN.
Antwort: C
Begründung:
Here's why:
FastConnect: FastConnect provides a dedicated, private network connection between your on-premises network and your OCI VCN. This offers several advantages:
Enhanced Security: Data travels over a private connection, bypassing the public internet, which significantly reduces the risk of interception or eavesdropping.
Higher Bandwidth and Lower Latency: FastConnect offers higher bandwidth and lower latency compared to internet-based connections, resulting in improved application performance.
Consistent Performance: Dedicated connectivity provides more consistent network performance, as it is not subject to the fluctuations of the public internet.
Why other options are less suitable:
a) Connect directly using the public IP address of the Autonomous Database: While this is technically possible, it's generally not recommended for production environments, especially when security is a primary concern. Exposing the database directly to the public internet increases the attack surface and exposes it to potential security threats.
b) Use an IPSec VPN tunnel between your on-premises network and your OCI VCN: While a VPN provides a secure connection over the internet, it typically offers lower bandwidth and higher latency compared to FastConnect. It's a good option for less demanding workloads or when FastConnect is not feasible, but FastConnect is preferred for dedicated, high-performance connectivity.
d) Configure a reverse proxy server in your OCI VCN: A reverse proxy can provide some security benefits, but it doesn't establish a dedicated connection. It still relies on an internet-based connection, which has the same security and performance limitations as connecting directly using the public IP.
39. Frage
What is the main requirement for subscribing to Oracle Database@Azure?
- A. An existing Azure subscription
- B. Linked Azure and Oracle Cloud Infrastructure account
- C. Custom Identity domain
- D. Private interconnect between OCI and Azure
Antwort: A
Begründung:
Oracle Database@Azure is offered within the Azure environment. 1 Therefore, having an active Azure subscription is a fundamental requirement to deploy and use this service. You're essentially deploying Oracle resources within your Azure tenancy Here's why the other options are not prerequisites:
B). Custom Identity domain: While identity management is important, a custom identity domain is not a strict prerequisite. Standard Azure identity mechanisms can be used.
C). Linked Azure and Oracle Cloud Infrastructure account: While the underlying technology involves connectivity between OCI and Azure, you don't need to explicitly link separate OCI and Azure accounts as a prerequisite. The integration is handled behind the scenes by Microsoft and Oracle.
D). Private interconnect between OCI and Azure: The Oracle Database@Azure service itself uses a private interconnect behind the scenes, but you, as the customer, don't need to set up a separate private interconnect as a prerequisite to subscribing to the service. The interconnect is part of the offering.
40. Frage
Which type of traffic is NOT supported by the cross-cloud connection between OCI and Microsoft Azure?
- A. Traffic between the Azure VNet and OCI VCN using private IP addresses
- B. Traffic from the Azure VNet to a peered OCI VCN in the same OCI region
- C. Traffic between your on-premises network and the OCI VCN through the Azure VNet
- D. Traffic from the Azure VNet to a peered OCI VCN in a different OCI region
Antwort: C
Begründung:
The OCI-Azure Interconnect supports direct traffic between Azure VNets and OCI VCNs (Option D) and peered VCNs in the same (Option B) or different OCI regions (Option A) via private IPs. However, it does not support transitive routing, such as traffic from an on-premises network through Azure to OCI (Option C), as the interconnect is a direct cloud-to-cloud link. This limitation is detailed in Oracle's networking documentation for the OCI-Azure partnership.
41. Frage
During provisioning in Oracle Database@Azure, delegated subnets are linked with OCI VCN inside the OCI pods in Azure. When do you perform this step during provisioning?
- A. Delegated subnets attachment happens when you provide the subnet details during provisioning of Oracle Exadata Database Service in Azure.
- B. Delegated subnets attachment with OCI pods containing the Exadata Database Service is a prerequisite action that is completed during the OCI account linking.
- C. Delegated subnets attachment happens when you provide the subnet details during provisioning of Oracle Exadata VM Cluster.
- D. Delegated subnets attachment happens when you provide the VCN details during the provisioning of container databases in OCI.
Antwort: C
Begründung:
In Oracle Database@Azure, delegated subnets from an Azure VNet are linked to the OCI VCN within OCI pods during the provisioning of the Oracle Exadata VM Cluster. This step occurs in the Azure portal when you specify subnet details, enabling the Exadata infrastructure to communicate with Azure resources. Option A is incorrect as container databases are provisioned later in OCI, not Azure. Option B misplaces this as a prerequisite during account linking, and Option C is too vague, as it references the broader service rather than the specific VM Cluster step. Oracle's provisioning guide confirms this timing.
42. Frage
How does Oracle Database on Google Cloud make database management easier for customers?
- A. It automatically transfers all database management tasks to the Oracle Cloud Infrastructure console.
- B. It requires customers to use Oracle-specific management tools.
- C. It enables customers to manage databases through the Google Cloud console or Google Cloud automation tools.
- D. OCI offers a management console within Google Cloud to simplify database management.
Antwort: C
Begründung:
Oracle Database@Google Cloud simplifies management by allowing customers to use the Google Cloud console and GCP automation tools (e.g., Terraform) to provision and manage databases, integrating seamlessly with GCP workflows. It doesn't shift tasks to OCI (Option B), nor does OCI embed a console in GCP (Option C). Option D contradicts the multicloud ease-of-use goal. This is a key feature highlighted in Oracle's June 2024 Google Cloud partnership announcement.
