200-301 Question #1771: Real Exam Question with Answer & Explanation

Question

SIMULATION 69 Please use the "Tasks" and "Topology" tabs to complete this lablet. Topology Tasks Complete the tasks below: Task 1 Configure 802.1q trunks between Sw1 and Sw2 on ports E0/0 and E0/1. - Only permit VLANs 10, 11, and 30 on the trunks. Task 2 Using LACP, create a Port Channel between Sw1 and Sw2. - Combine E0/0 and E0/1 into a Port Channel while leaving the trunk configurations intact. - Assign number 10. - Only Sw1 should initiate negotiate. Answer: Task 1 - Configure 802.1Q trunks (only VLANs 10, 11, 30) On Sw1: conf t interface range e0/0 - 1 switchport trunk encapsulation dot1q switchport mode trunk switchport trunk allowed vlan 10,11,30 end On Sw2: conf t interface range e0/0 - 1 switchport trunk encapsulation dot1q switchport mode trunk switchport trunk allowed vlan 10,11,30 end Interfaces e0/0 and e0/1 on both switches are configured as 802.1Q trunks and restricted to VLANs 10, 11, and 30. Task 2 - Create LACP Port Channel 10 (Sw1 initiates) On Sw1 (LACP active - initiates negotiation): conf t interface range e0/0 - 1 channel-group 10 mode active exit interface port-channel 10 switchport mode trunk switchport trunk allowed vlan 10,11,30 end On Sw2 (LACP passive): conf t interface range e0/0 - 1 channel-group 10 mode passive exit interface port-channel 10 switchport mode trunk switchport trunk allowed vlan 10,11,30 end LACP is enabled by using mode active on Sw1 and mode passive on Sw2, creating Port-Channel 10 from e0/0 and e0/1. The port-channel is configured as an 802.1Q trunk permitting only VLANs 10, 11, and 30, maintaining the required trunk characteristics across the aggregated link.
