In Oracle Cloud Infrastructure (OCI) network monitoring, there are two primary services for capturing traffic data, each employing a distinct type of filtering. The VTAP (Virtual Test Access Point) service uses a resource called a Capture Filter, which contains specific rules to mirror designated network packets. Separately, VCN Flow Logs capture IP traffic metadata and can be configured with a filter to log either all traffic, only accepted traffic, or only rejected traffic for a subnet. These two mechanisms, "VTAP capture filters" and the filtering capability within "Flow log" configurations, represent the two types of capture filters.

A. "Flow control" is a network mechanism to manage data rates, not a type of capture filter in OCI. "Traffic capture filters" is too generic.

B. While VTAP performs packet capture, "packet capture filters" is a generic term. "VTAP capture filters" is the specific OCI service name, making option D more accurate.

C. "Network capture filters" is a generic category that includes VTAP filters, making this option imprecise and the pairing redundant.

1. Oracle Cloud Infrastructure Documentation, "VTAP, Capture Filters": "A capture filter contains a set of rules that you define. These rules specify the traffic you're interested in... You can associate a capture filter with a VTAP to mirror traffic from a source to a network load balancer." This source confirms the existence and purpose of "VTAP capture filters".

2. Oracle Cloud Infrastructure Documentation, "VCN Flow Logs": "You can configure flow logs to capture information about traffic that is accepted or rejected for a specific subnet... When you enable a flow log on a subnet, you can specify a filter to capture all traffic, only traffic that is rejected, or only traffic that is accepted." This source confirms the filtering capability for VCN Flow Logs.
