Description

1. A switch is participating in a VTP domain and configured as a VTP server. The switch needs to propagate VLAN 10 (used by the Manufacturing department) throughout the VTP domain, but does not have any directly connected hosts using that particular VLAN. Which configuration would satisfy this requirement? i nt er f acef a0/ 24 swi t chpor tmodeaccess swi t chpor tacces svl an10  vlan 10 name Manufacturing exit* v t pmodes er v er v t ppas s wor dManuf ac t ur i ng i nt er f aceg0/ 1 s wi t chpor tmodet r unk s wi t chpor tt r unknat i v ev l an10 Thebes tpr ac t i cet oaddaVLANt ot heVLANdat abas ewi t hnol oc alhos t st obei nt hatVLANi st o confi gur et hatVLAN( vl an10)wi t hi t sname( nameManuf act ur i ng)andus et heexi tcommandt ocompl et e t heconfigur at i on.Donotas si gnanys wi t c hi nt er f acest ot hatVLAN. 2.
