VTP Questions

September 15th, 2017 in SWITCH 300-115 Go to comments

Question 1

Explanation

VTP updates can only be forwarded on trunk links.

Question 2

Explanation

VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.

Question 3

Explanation

VTP Pruning makes more efficient use of trunk bandwidth by forwarding broadcast and unknown unicast frames on a VLAN only if the switch on the receiving end of the trunk has ports in that VLAN. In the below example, Server switch doesn’t send broadcast frame to Sw2 because Sw2 doesn’t have ports in VLAN 10.

Question 4

Explanation

Switch C can receive VLAN information from Switch A so Switch B can forward it to Switch C without updating its VLAN database -> Switch B is in VTP transparent mode.

Question 5

Explanation

VTP updates can only be forwarded on trunk links.

Question 6

Explanation

VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.

Question 7

Explanation

Question 8

Explanation

VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.

Question 9

Explanation

If a VTP client or server with a null domain receives a VTP message with the domain populated, it will assume the domain of the received message and add applicable VLANs to its database.

Question 10

Explanation

VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.

    Hi, regarding Q 10 – looks correct to me
    Extended Vlans
    Not supported in VTP Versions 1 and 2. The switch must be in VTP transparent mode to configure extended-range VLANs. This range is only supported in Version 3.
    good luck

    Q10. Biddu and the others are right the answer is A. (Transparent.) The question refers to mode not version.

    You can create extended vlans in VTP V1&2 in transparent mode, but transparent mode does not propagate any vlans (including extended VLANs). You can only propagate extended VLANs using VTP v3.
