Practise switch scenarios involving SW1, SW2, VLANs, trunk links, allowed VLAN lists and show interfaces trunk output.
Start Scenario PracticeA switchport connected to another switch should carry multiple VLANs, but it was manually configured as an access port. What is the most likely operational result?
Explanation: An access port is designed to carry only a single VLAN. If the link is intended to carry multiple VLANs, it must be configured as a trunk. The switch will not automatically convert the port to a trunk (B). The port remains a Layer 2 access port, not a routed Layer 3 interface (C). VLANs are not automatically summarized into a single prefix (D). The most likely result is that the link will not carry multiple VLANs as intended.
Which three of the following statements about VLAN Trunking Protocol (VTP) are correct? (Choose three.)
Explanation: All three selected statements are correct: VTP pruning reduces unnecessary broadcast traffic by pruning inactive VLANs from trunk links; a VTP server can create/modify/delete VLANs and propagates changes; transparent mode forwards advertisements but does not synchronize. The three distractors are incorrect. D: VTP version 3 is not backward compatible with version 1 and 2; it requires compatible versions. E: A VTP client cannot create local VLANs; it only synchronizes from the server. F: VTP uses multicast MAC address 0100.0CCC.CCCC for advertisements, not 0180.c200.0000 which is used by other protocols like STP.
An engineer configures 802.1X port-based authentication on a Cisco IOS-XE switch for a voice VLAN deployment. After applying the configuration, IP phones on interface GigabitEthernet1/0/1 fail to receive a voice VLAN and remain in an unauthenticated state. The switchport is configured as an access port with voice VLAN 10. What is the most likely cause of the failure?
Explanation: The correct answer is B because in a voice VLAN deployment with 802.1X, the switchport must be configured with 'authentication host-mode multi-domain' to allow both a data device (phone) and a voice device (PC behind the phone) to authenticate separately. Without this mode, the port defaults to single-host mode, which prevents the phone from receiving the voice VLAN and keeps it in an unauthenticated state.
A network engineer configures an EtherChannel between two Cisco switches SW1 and SW2 using LACP. After configuration, hosts connected to SW1 report intermittent connectivity to hosts on SW2. The engineer checks the EtherChannel status and sees that the trunk is up but only allows VLAN 1, while the hosts communicate across VLANs 10 and 20. Which command should the engineer apply to both switches to resolve the issue?
Explanation: The output shows the EtherChannel is up but only VLAN 1 is allowed on the trunk, while the hosts on SW1 and SW2 communicate across VLANs 10 and 20. Applying 'switchport trunk allowed vlan 1,10,20' on both switches ensures all necessary VLANs are permitted over the EtherChannel, resolving the intermittent connectivity caused by dropped traffic for VLANs 10 and 20.
Drag and drop the steps into the recommended configuration order for setting up VLANs, assigning access ports, configuring 802.1Q trunking with a non-default native VLAN, and verifying the setup on a Cisco IOS-XE switch.
Explanation: After creating VLANs, the recommended order is to configure trunking with a non-default native VLAN before assigning access ports. This ensures the trunk is ready with the correct native VLAN, preventing mismatches and allowing the switch to carry traffic for the new VLANs. Options B and D fail because VLANs must exist first. Option A places trunking last, which is not the best practice.
