VLAN Trunking 3

September 16th, 2017 in SWITCH 300-115 Go to comments

Question 1

Explanation

The “vlan dot1q tag native” command maintains the tagging on the native VLAN and drop untagged traffic -> B is correct.

Reference: http://www.cisco.com/web/techdoc/dc/reference/cli/nxos/commands/l2/vlan_dot1Q_tag_native.html

Question 2

Note: Answer F is not correct because VLAN 600 is the native VLAN on Gi6/2 does not mean untagged traffic is tagged with this VLAN. It only means “all untagged traffic belongs to VLAN 600”.

Question 3

Question 4

Question 5

Question 6

Explanation

Although Gi0/10 has been configured as trunk it it did not appear in the “show interfaces trunk” command so the most suitable reason is it is down (not administratively down but down for another reason).

Question 7

Explanation

By entering the command “switch port trunk allowed vlan 2,3,4”, vlan 5 would be removed from allowed VLAN list. Both Workstations A & B are on VLAN 5 so they cannot communicate any more.

Note: If we want to add vlan 2 to 4 to the allowed VLAN list then we should use the “switchport trunk allowed vlan add 2,3,4”.

    Why the answer on question 6 is D? I saw the configuration on interface FastEthernet0/2 (sw02) and on interface FastEthernet0/1 (sw01) that allows vlan 5…………….

    MaryCisco:
    Read Question carefully.
    it says “the effect of entering the switchport trunk allowed vlan 2,3,4 command”.

    Q5 Why is the answer not “A”?

    Q6 And Rizwan is right. The interface is showing on show vlan, wouldn’t that mean that the interface is active or up?

    The Q4 is correct? The dynamic auto in both sides not will form a trunk port?
