Correct : B

When ensuring that third-party APIs communicate securely with OCI resources, the appropriate authentication option is API Signing Key.

API Signing Key: This method uses an RSA key pair to authenticate and sign API requests. The API signing key provides a secure and reliable way to ensure that the API requests to OCI are coming from an authorized source. It is commonly used for programmatic access to OCI services.

Other Options:

SSH Key Pair: Primarily used for secure shell access to compute instances, not for API authentication.

Auth Tokens: Typically used for authentication in environments where APIs don't support the API Signing Key, such as OCI CLI or SDKs.

OCI Username and Password: Generally used for the Console login, not for securing API communications.

Relevant OCI Documentation:

API Signing Key Authentication

This documentation provides details on using API Signing Keys for secure API communication in OCI.

Correct : A

The Network Visualizer tool in Oracle Cloud Infrastructure is valuable because it visualizes the topology of all Virtual Cloud Networks (VCNs) in a selected region and tenancy.

Topology Visualization: The Network Visualizer provides a graphical representation of the network components and their relationships within a VCN, including subnets, route tables, gateways, and security lists. This visualization helps users understand the network architecture and troubleshoot issues effectively.

Other Options:

Real-time monitoring of network traffic (B), detailed information about physical network components (C), and automated reports on network performance metrics (D) are not the primary functions of the Network Visualizer. These functionalities are typically handled by other OCI services or tools.

This documentation details the features and benefits of the Network Visualizer tool in OCI.

Correct : C

To securely grant a third-party application access to specific Oracle Cloud Infrastructure (OCI) resources, the recommended approach is to configure the application to use Instance Principal. This method allows the application to authenticate directly with OCI services without needing to manage sensitive credentials like passwords or API keys.

Instance Principals: Enable compute instances to directly make API calls against OCI services, inheriting permissions through IAM policies. This setup is more secure than sharing user credentials, as it avoids hardcoding credentials within the application and leverages OCI's native security features.

Correct : A

Geolocation Steering in OCI's Traffic Management Steering Policy allows you to distribute DNS traffic based on the geographical location of the end users. This method helps direct users to the nearest regional endpoint, optimizing latency and improving user experience.

Use Cases: Geolocation Steering is commonly used to deliver region-specific content, comply with data residency laws, or optimize service performance by directing traffic to the closest available servers.

Correct : B

To delegate a domain to the Oracle Cloud Infrastructure (OCI) DNS service, the domain needs to be pointed to OCI's DNS servers. This can be done through the Domain Registrar's self-service portal, where you update the name servers for your domain to OCI's DNS servers.

Process: You typically log into the domain registrar where your domain is registered and replace the existing name servers with the name servers provided by OCI DNS. Once this is done, DNS queries for your domain will be directed to OCI DNS.
