Refer to the exhibit. Your colleague has built a Layer 2 network in your client locations. You must verify the configuration and fix any issues identified as per customer requirements. Customer requirements: + Verify if switch ports are assigned correct VLANs as shown in topology. Identify and fix any misconfiguration found in three switches + Verify if trunk links are operational between switches and the IEEE 802.1Q trunk encapsulation method is used. Identify and fix any misconfiguration found in trunk configuration + Make sure ports connected between switches are set as trunk ports We are not sure about the details but here are the faults in this sim: – Native VLAN mismatch between SW1 & SW3 – Switchport mode mismatch: one in access mode while the other end in trunk mode -> need to change from access to trunk mode – One port in VLAN 500 while other port in VLAN 600 Recommended commands to solve this sim: show int trunk, show vlan, show run. You can download and practice this sim with Packet Tracer at: https://www.9tut.com/download/9tut.com_CCNA_VLAN_Troubleshooting_Sim.zip Commands to fix the issues: SW1, SW2: interface e0/2 switchport mode access switchport access vlan 500 interface e0/3 switchport mode access switchport access vlan 600 SW3: interface e0/0 (or interface e0/1 of SW1) switchport trunk encapsulation dot1q switchport mode trunk switchport trunk native vlan … (must match the native VLAN on the other end, use “show int trunk” command on SW1 to check SW1 native VLAN)
