D. nvram:vlan.txt
E. flash.config.txt
F. flash:vlan.xml

 

Answer: A

Question 5

Question 6

Question 7

Explanation

Let’s see an example of configuring this command.

Cisco_IP_Phone_data_voice_VLANs.jpg

Switch(config)#interface fa0/0
Switch(config-if)#switchport voice vlan 30

The “switchport voice vlan 30” command directs the switch to send CDP packets that configure the IP phone to transmit voice traffic in 802.1Q frames, tagged with VLAN 30. The data traffic is sent to the native VLAN (untagged).

Therefore in this question both answer A and D are correct. I don’t know why we only have one choice in this question.

    Q1. The extended range is quite confusing as Cisco seems to contradict themselves. According to this page extended range is 1006-4096:

    Extended range VLANs (VLANs 1006 to 4096)

    What would happen if we delete VLAN that exist on switchport?
    A. Port down and use native VLAN.
    B. Port down and use default VLAN.
    C. Port up and use native VLAN.
    D. Port up and use default VLAN.
    E. Port will remain shutdown/inactive until it is assigned a new VLAN.

    This is E for sure. Just tried it on a real switch.

    Switch-1#show interfaces gigabitEthernet 0/1 swi
    Switch-1#show interfaces gigabitEthernet 0/1 switchport
    Name: Gi0/1
    Switchport: Enabled
    Administrative Mode: static access
    Operational Mode: down
    Administrative Trunking Encapsulation: dot1q
    Negotiation of Trunking: Off
    Access Mode VLAN: 100 (Inactive)
    Trunking Native Mode VLAN: 1 (default)
