Which two options are considerations for using WSA to obtain a full network traffic picture?

1. It monitors all traffic on the interface

2. It monitors only routed traffic

3. It is unable to monitor over time

4. It monitors only ingress traffic

The correct answer is: It monitors all traffic on the interface

Using Web Security Appliance (WSA) to obtain a full network traffic picture relies on its ability to provide comprehensive visibility into the network's traffic patterns. Monitoring all traffic on the interface allows the WSA to analyze and report on both inbound and outbound traffic flows, giving a holistic view of data usage and patterns across the network. This capability is essential because it enables administrators to identify trends, detect anomalies, and enforce security policies effectively. Focusing exclusively on types of traffic, the option indicating that WSA monitors only routed traffic would limit its visibility and prevent it from capturing critical information. Similarly, the inability to monitor over time would undermine the effectiveness of traffic analysis for long-term insights about network performance and security posture. Lastly, monitoring only ingress traffic would result in a fragmented view, missing important details about how data exits or is transmitted throughout the network. Overall, the ability to monitor all traffic on the interface is crucial for leveraging WSA effectively, allowing organizations to strengthen their security frameworks while gaining an accurate understanding of their overall network performance.
