813题库151题的，PDF上VRRP题目答案错了，应该是A吧，regain是重新获得，maintain是保持
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.
Answer: C
Section: HSRP, VRRP, GLBP
Explanation/Reference:
A的priority比较高，故A为active，但由于没有配置preempt，故当A fail后 B成为active，然后A也起来后，B
还是active。

还有158题目中也不是很理解
A. multipoint control unit (MCU) Catalyst_A.
B. Hosts using the default gateway address of 192.168.1.1 will have their traffic sent to 192.168.1.11 even
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.
Answer: AC
Section: HSRP, VRRP, GLBP
Explanation/Reference:
虚拟IP为192.168.1.2。
而且他在VLAN50中配置了两个HSRP组，实现load sharing
解释和选项不搭啊，中文解释意思是说选AD,而题目选了AC，莫非C选项中网关指向和数据流向体现了load sharing
？

应该是题目答案有误，从图看起来只有选项D是正确的，选项C不多，图明显说明白了是虚拟网关192.168.1.2的备用，standby router is local,所有数据不会流向Catalyst_A.

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.

正确，VRRP虽然没配置preempt，但是默认了抢占功能。HSRP不默认。


D. Catalyst_A is load sharing traffic in VLAN 50.正确，另一项有几个版本选项不同，楼上这个版本比较靠谱。
