Remote peering in Oracle Cloud Infrastructure allows two VCNs in different regions to communicate securely. To establish remote peering, the following components are required:

Two VCNs with Nonoverlapping CIDRs:

The CIDR blocks of the two VCNs must not overlap. This is crucial to avoid routing conflicts and ensure that traffic is correctly routed between the VCNs.

Dynamic Routing Gateway (DRG) Attached to Each VCN:

A DRG is a virtual router that provides a path for traffic between the VCN and networks outside the VCN, such as other VCNs via remote peering, on-premises networks, or other cloud services.Each VCN needs its own DRG.

Remote Peering Connection (RPC):

An RPC is a specialized connection on the DRG used specifically for remote peering. You need to create an RPC on each DRG associated with the VCNs you wish to peer.

Connection Between RPCs:

Finally, a connection must be established between the RPCs of the two DRGs. This connection facilitates the secure and private exchange of traffic between the VCNs over Oracle's backbone network.

Incorrect Options:

Option Ainvolves a single VCN, which does not fulfill the requirement of remote peering between two VCNs.

Option Binvolves overlapping CIDRs and VPN gateways, which are incorrect for remote peering.

Option Csuggests peering within the same region, which would be considered local peering rather than remote peering.

To allow access to Oracle Cloud Infrastructure (OCI) File Storage Service (FSS) for a Database (DB) System with read-only permissions, you should create anNFS export optionthat specifiesREAD_ONLYaccess.

NFS Export Options:These options define the access permissions (read/write or read-only) for clients connecting to the file system. By setting the export option toREAD_ONLY, you ensure that the DB System can only read from the FSS and cannot modify or delete files.

The principle of least privilege is a security best practice that dictates that users should only be granted the minimum set of permissions necessary to perform their tasks. This principle helps to minimize the risk of accidental or malicious actions that could compromise security.

IAM Policies in OCI:When creating IAM policies in OCI, you should carefully evaluate the required permissions and only grant those that are absolutely necessary for the users or groups to perform their specific roles. This helps to reduce the attack surface and prevent unauthorized access to sensitive resources.
