Why each option

To analyze traffic from the file server on SW1 using a packet analyzer, the engineer needs to configure a SPAN session and then verify its setup.

ASW1#show monitorCorrect

The `show monitor` command is used to display the current configuration and operational status of all configured SPAN (Switched Port Analyzer) sessions, allowing verification that traffic mirroring is active.

BSW1(config)#monitor session 1 source interface gigabitethernet0/3Correct

The `monitor session 1 source interface gigabitethernet0/3` command configures GigabitEthernet0/3 as the source port for SPAN session 1, instructing the switch to copy all traffic from this interface to the configured destination port for analysis.

CSW1#show ip route

The `show ip route` command displays the routing table, which is irrelevant for configuring or verifying a SPAN session.

DSW1#show vlan

The `show vlan` command displays VLAN information, which is not directly related to configuring or verifying a SPAN session.

ESW1(config)#monitor session 1 source interface gigabitethernet0/1

Configuring `gigabitethernet0/1` as the source interface would be incorrect if the file server is connected to `gigabitethernet0/3`.
