Answer : A, D, E

A Dynamic Routing Gateway (DRG) in Oracle Cloud Infrastructure (OCI) is a virtual router that provides a path for private traffic between your on-premises network and your VCN, or between your VCN and other VCNs. The resources that can be attached to a DRG include:

A . Virtual Circuits: Used to establish a private connection between your on-premises data center and your VCN via Oracle's FastConnect service.

D . Remote Peering Connections: Enables peering between VCNs located in different regions (Remote VCN Peering).

E . IPSec Tunnel: Facilitates secure VPN connections between your on-premises network and your OCI VCN.

OCI Confidential Computing is a security feature designed to protect data in use. This is particularly important for sensitive workloads where data must be secured not only when at rest or in transit but also while being processed.

Encrypts and Isolates In-Use Data: OCI Confidential Computing ensures that data and the applications processing it are isolated from the underlying infrastructure. This means that even if the infrastructure is compromised, the in-use data remains secure. The technology typically leverages secure enclaves or other hardware-based isolation mechanisms to achieve this.

Other Options:

Optimizing Network Performance (A), Automatic Scalability and Load Balancing (B), and Secure Data Storage (D) are important features, but they are not related to the core capabilities of Confidential Computing, which focuses on in-use data protection.

This documentation provides a detailed explanation of how OCI Confidential Computing works and its benefits for securing sensitive data during processing.

Answer : 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.

Answer : D

In Oracle Cloud Infrastructure (OCI), there are two primary types of capture filters used for network monitoring:

Flow Log Capture Filters: These filters are used to capture and log network flow information (e.g., source and destination IP addresses, ports, protocols). Flow logs provide insights into the traffic patterns within your VCN.

VTAP Capture Filters: Virtual Test Access Point (VTAP) capture filters allow you to capture and inspect traffic from specific network interfaces or subnets without affecting the flow of traffic. This is particularly useful for deep packet inspection and monitoring purposes.

Answer : C

When Cross-Region Replication is enabled for a block volume in Oracle Cloud Infrastructure (OCI), the replication process automatically creates and maintains a synchronized copy of the block volume in the selected destination region (in this case, US West (San Jose)).

Replica Availability: The replicated volume is immediately available as a block volume in the destination region. You do not need to take any additional action to activate or trigger the replica.

Creating New Volumes: Since the replica is automatically available as a block volume, you can directly use it to create a new volume in the destination region without any manual intervention.
