Exam 350-401 topic 1 question 162 discussion

I think the correct answer is D

Hi, VRRP enables preemption by default. So, i would put instead : vrrp 10 priority ..

The virtual IP must be within the same subnet as the IP addresses of the physical interfaces on the routers participating in the HSRP or VRRP group. HSRP uses 'standby 10 IP 172.16.13.254', and 'standby 10 preempt' commands, while VRRP uses a different set of commands 'VRRP 10 IP 172.16.12.254', and 'VRRP 10 preempt'.

D is correct B is wrong, the question says when the router has the highest priority in the group, it must assume the master role, so we dont have to specify the priority. And if we assume that B has 120 at the end, it will be wrong too, since "group" command is incorrect, and subnet mask should not be included in the VRRP configuration command.

There has got to be something wrong with this question because preempt is enabled by default on VRRP and there's no value listed for the priority which means everything is set to defaults. none of it makes any sense

Admins, please, these badly formatted questions needs to be fixed.

correct 100%

D is correct

D is the answer only because the other three answers are totally incorrect. But D is also only half correct.

D.- vrrp 10 ip 172.16.13.254 vrrp 10 preempt

There is no standby command used for vrrp. D is the correct answer

D is correct, there is no standby cmd used for vrrp.

the correct one is D

The correct answer is D.

I totally agreed with Ramona88. D is correct because Standby command isn't used in VRRP.

A. standby 10 ip 172.16.13.254 255.255.255.0 standby 10 preempt (WRONG - Standby is HSRP syntax) B. vrrp group 10 ip 172.16.13.254 255.255.255.0 vrrp group 10 priority (WRONG - word "group" is command in VRRP) C. standby 10 ip 172.16.13.254 standy 10 priority 120 (WRONG - Standby is HSRP syntax) D. vrrp 10 ip 172.16.13.254 vrrp 10 preempt (Correct)
