問題 #14
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. Configure a reverse proxy server in your OCI VCN.
B. Use FastConnect to establish a dedicated connection between your on-premises network and your OCI VCN.
C. Use an IPSec VPN tunnel between your on-premises network and your OCI VCN.
D. Connect directly using the public IP address of the Autonomous Database.

答案：B

解題說明：
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.

問題 #15
Which type of traffic is NOT supported by the cross-cloud connection between OCI and Microsoft Azure?

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

答案：D

解題說明：
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.

問題 #16
What comprises the physical architecture of Oracle Database@Azure?

A. Oracle places three OCI availability domains, one in each of the three Azure availability zones.
B. Oracle creates an OCI pod closest to the Azure Data Center and connects it with the nearest OCI region by a low-latency Oracle-managed network link.
C. OCI pods in Azure data centers contain the Exadata Database Service stack, but all other dependencies and controls reside in the nearest OCI data center.
D. OCI pods created inside the Azure data center are an extension of the OCI data center with the same OCI infrastructure, service stack, Exadata Database Service, and all dependencies.

答案：D

解題說明：
The physical architecture of Oracle Database@Azure consists of OCI pods deployed within Azure data centers, fully equipped with OCI infrastructure, Exadata Database Service, and all dependencies, acting as an extension of OCI. Option A incorrectly splits dependencies, Option C misrepresents the pod location, and Option D confuses OCI ADs with Azure zones. Oracle's architecture docs confirm this co-located, self-contained design.

問題 #17
When configuring the network for Oracle Database@Google Cloud, what is the purpose of the Autonomous System Number (ASN)?

A. It assigns IP addresses to the Exadata compute nodes
B. It identifies the network of each cloud provider (OCI and Google Cloud) for BGP routing.
C. It encrypts the traffic between OCI and Google Cloud.
D. It authorizes access to the Exadata systems from Google Cloud.

答案：B

解題說明：
An Autonomous System Number (ASN) is a unique identifier assigned to an autonomous system, which is a network or a collection of networks under a common administration. 1 In the context of connecting OCI and Google Cloud, each cloud provider has its own ASN. These ASNs are used in BGP (Border Gateway Protocol) routing to exchange routing information between the two networks. 1 BGP uses ASNs to determine the best path for network traffic to travel between different autonomous systems.

問題 #18
What is the purpose of Google Cloud Virtual Private Cloud (VPC) in the context of Oracle Database@Google Cloud?

A. To provide public internet access to Oracle database services
B. To manage billing for Oracle Database@Google Cloud
C. To isolate Oracle database services from other Google Cloud resources for security reasons
D. To enable direct connectivity to OCI regions

答案：C

解題說明：
In Oracle Database@Google Cloud, Google Cloud Virtual Private Cloud (VPC) is used to create an isolated network environment within GCP, securing Oracle database services from other resources. This isolation enhances security by restricting access to the databases and ensuring they operate within a private subnet. Option B contradicts the private nature of the service, while Options C and D are unrelated to VPC's role. Oracle's documentation on Database@Google Cloud emphasizes VPC for network segmentation and security.
