its C & E. Please refer to the link below https://community.cisco.com/t5/switching/understanding-standby-preempt/td-p/1870591

answer AC

The router that has highest priority will be in the active state. In HSRP protocol, the preempt command is disabled by default, so when R1 goes down, R2 will take action and be the Active router and remain in the Active state even R1 back to up. Note: when you enable preempt command on both routers, when R1 came up it will return his state as Active router.

C & E are correct

C is only the active router if it was booted first, or configured first. D can also be correct if R2 was booted or configured before R1. It's a dumb question, probably not correct, but I wouldnt put it past Cisco to ask us these asinine questions. We have to assume R1 was booted and configured first. BeCaUsE 1 CoMeS BeFoRe 2... However, none of the other answers (A,B) are correct because regardless there is no preempt command. So the router to stay online will retain as Active. The routers will not revert to standby unless the active router goes down or the pre-empt command is put on the standby router. I am going with C, because of logic, and E because that is actually the only other true answer.

R1 becomes the active router because the router with highest priority becomes the active router. This makes C correct, There is no Standby preempt statement on R1 so if it goes down, R2 takes over and R1 never becomes active even if it comes up again till R2 goes down.

C because R1 will be in active state (priority 120) after applying the configurations and while R1 is still up . however, E is the effect of the configurations after R1 goes down R2 will be active and remain active due to no preempt con both routers.

Agree with answer E but so not agree with C how can R1 be active if it went down and recovered but there is no preepmt command to make it active again. So in my opinion only E

No preempt vommand configured

C + E is correct

C and E are correct

router with higher priority will become active, without preempt r1 will not become active after come online. preempt is not a default command with hsrp

Preempt is not enabled

Preempt is not enabled, if R1 goes down it will not become active again.

Correct answers: CE Preempt is not configured on R1 hence R2 will remain as the active Router.

Preempt is not configured on R1 hence R2 will remain as the active Router. https://www.cisco.com/c/en/us/support/docs/ip/hot-standby-router-protocol-hsrp/13780-6.html

CE for sure! Because the preempt keyword is not used, R1 will not become Active if it goes down and comes back online
