求高手解答，这两张图关于trunk与hybird配置顺序有问题吗？
取自GB370.v200题库38题与42题，感觉答案有问题。

hybird配置是需要先有vlan 才可以进行端口配置的
而trunk配置是没有这个vlan也是可以配置上去的


我用LITO模拟器测试的

首先有1—10的vlan

[SW1]dis vlan
Total 10 VLAN exist(s).
The following VLANs exist:
  1(default), 2-10,


首先验证trunk的配置顺序
[SW1]int e0/4/0
[SW1-Ethernet0/4/0]port link-type trunk
[SW1-Ethernet0/4/0]port trunk pvid vlan 12
[SW1-Ethernet0/4/0]port trunk permit vlan 13
interface Ethernet0/4/0
port link-mode bridge
port link-type trunk
port trunk permit vlan 1 13
port trunk pvid vlan 12


查看端口：
[SW1-Ethernet0/4/0]dis int e0/4/0
Ethernet0/4/0 current state: UP
IP Packet Frame Type: PKTFMT_ETHNT_2, Hardware Address: 0000-5601-0000
Description: Ethernet0/4/0 Interface
Loopback is not set

100Mbps-speed mode, full-duplex mode
Link speed type is force link, link duplex type is autonegotiation
Flow-control is not enabled
The Maximum Frame Length is 1500
Broadcast MAX-ratio: 100%
Unicast MAX-ratio: 100%
Multicast MAX-ratio: 100%
Allow jumbo frame to pass
PVID: 12
Mdi type: auto
Port link-type: trunk
  VLAN passing  : 1(default vlan)
  VLAN permitted: 1(default vlan), 13
  Trunk port encapsulation: IEEE 802.1q  
trunk端口的配置没问题 是允许配置不存在的vlan的




现在验证hybrid端口配置
[SW1-Ethernet0/4/1]port link-type hybrid
[SW1-Ethernet0/4/1]port hybrid  vlan 20 tagged
Error: Only the existing static VLANs could be added.（报错了）
[SW1-Ethernet0/4/1]port hybrid pvid vlan 30（hybrid端口也就是说可以配置没有的vlan 作为此端口的缺省vlan）
      
现在创建了vlan20
[SW1-vlan20]int e0/4/1

[SW1-Ethernet0/4/1]port hybrid vlan 20 tagged
Please wait... Done.（成功配置）
[SW1-Ethernet0/4/1]dis this
#
interface Ethernet0/4/1
port link-mode bridge
port link-type hybrid
port hybrid vlan 20 tagged
port hybrid vlan 1 untagged
port hybrid pvid vlan 30
#

第38题的B已经创建了VLAN10和20但是为什么还不对
