Is this a use case for deploying Ethernet Ring Protection Switching (ERPS)?
Solution: extending Layer 2 communications between data centers that connect over Layer 3 MPLS links
Based on the exhibits, Switch-1 has a trunk port on 1/1/1 that allows VLANs 10 and 20. Switch-2 has an access port on 1/1/2 that belongs to VLAN 10. Switch-3 has an access port on 1/1/3 that belongs to VLAN 20. If a broadcast arrives with a VLAN 10 tag on 1/1/1 on Switch-1, Switch-1 does not drop the frame. Instead, Switch-1 forwards the frame to all ports that belong to VLAN 10, which includes the trunk port 1/1/2 and the access port 1/1/4. Switch-2 receives the frame on its access port 1/1/2 and forwards it to all ports in VLAN 10, which includes the access port 1/1/5. Switch-3 does not receive the frame because it is not in VLAN 10. Therefore, this is not how the switch handles the traffic, and the correct answer is no.
