Which Virtual Router Redundancy Protocol (VRRP) statement is true about the roles of the master virtual
router and the backup virtual router?
图为158
A.Router A is the master virtual router, and Router B is the backup virtual router. When Router A fails,
Router B will become the master virtual router. When Router A recovers, Router B will maintain the role
of master virtual router.
B.Router B is the master virtual router, and Router A is the backup virtual router. When Router B fails,
Router A will become the master virtual router. When Router B recovers, it will regain the master virtual
router role.
C.Router A is the master virtual router, and Router B is the backup virtual router. When Router A fails,
Router B will become the master virtual router. When Router A recovers, it will regain the master virtual
router role.
D.Router B is the master virtual router, and Router A is the backup virtual router. When Router B fails,
Router A will become the master virtual router. When Router B recovers, Router A will maintain the role
of master virtual router.
大侠们这个选哪个啊？

after Catalyst_A becomes available again.
C.Hosts using the default gateway address of 192.168.1.2 will have their traffic sent to Catalyst_A.
D.Catalyst_A is load sharing traffic in VLAN 50.

A.switchport dynamic auto
switchport dynamic auto

switchport mode dynamic desireable

第一道我已发过帖子http://bbs.hh010.com/thread-85104-1-1.html 我正在准备813，发现158题很奇怪，想不通，有牛人帮忙看看解答下吗？？谢谢 158题的答案是对的，但是解析错了！vrrp默认是开启抢占模式的！！！鉴定完毕！ 关于286：'switchport access vlan 10' doesn't put interface into access mode (as 'switchport mode access' does), so with the default configuration and 'switchport mode dynamic desireable' on another side, you'll get working trunk. So answer B is correct. 本帖最后由 祈祷ing 于 2012-5-15 21:42 编辑
158Q感觉题库有问题，虽然我马上也要考158Q A交换机有2个组 GROUP1 在A交换机上是活动的 GROUP2活动的是192.168.1.11 也就是VLAN50在A交换机里GROUP1是活动的另外一个交换机上的VLAN50也是活动的 所以VLAN50就达到了负载分担的效果。另外 如果 把网关指向192.168.1.2 的话他是不会把数据包给A的，因为192.168.1.2 属于GROUP2的，但是GROUP2在A上不是活动的。所以我认为此题答案选AD~~~~286Q题库也是由问题的 因为选哪个吧接口直接划入trunk的才对 ，选D 本帖最后由 keyhappy 于 2012-8-9 16:14 编辑
