Correct Answer: B
To monitor and export traffic to a Network Analyzer, particularly ingress traffic from Host-A and all traffic for VLAN 20 from Host-B, the engineer must implement a configuration that captures the specified traffic and directs it to the Network Analyzer tool. The correct configuration will depend on the capabilities of the network devices in use and the specifics of the Network Analyzer's requirements.
The configuration must include setting up a SPAN (Switched Port Analyzer) or RSPAN (Remote SPAN) session that mirrors the desired traffic to a port connected to the Network Analyzer. This would involve specifying the source interfaces or VLANs and the destination port for the mirrored traffic. Additionally, the configuration should ensure that the Network Analyzer is capable of receiving and processing the mirrored traffic, which may require additional settings on the Network Analyzer itself.
