Exam 350-401 topic 1 question 45 discussion

HSRP v1 allow only 265 group numbers. HSRP v2 allow 4096 group number

In HSRP version 1, group numbers are supported the range from 0 to 255 and HSRP version 2 expands the group number range from 0 to 4095. * So it should HSRP v2 to assign the group no. 300 (So. the ans should A or C). * Default priority of the HSRP is 100 and the Router with higher priority no. will become Active Router. So the priority set over 100 for active router. So, the answer is "A".

The correct answer is: A. cisco Copy Edit standby version 2 standby 300 priority 110 standby 300 preempt Explanation: HSRP Default Priority: The default priority for HSRP is 100. To make this router the active router, its priority must be higher than 100. Option A sets the priority to 110, which is higher than the default. Preempt Feature: standby 300 preempt ensures that if this router comes online after a failure, it will take back the active role (if it has the highest priority). Without preempt, the router will not take over even if it has the highest priority. HSRP Version 2: standby version 2 enables HSRP version 2, which supports larger group numbers (0-4095) and IPv6. Not mandatory but often recommended for modern networks.

A is correct

A is correct

Correct answer is indeed A.

Default priority value is 100 so if we make priority from 101 they router will act as primary router to forward the traffic

A is correct

Answer A standby version 2 standby 300 priority 110 standby 300 preempt

B. standby 300 priority 110 standby 300 timers 1 110 Explanation: The "standby 300 priority 110" command sets the priority of the router to 110, making it higher than the default priority of the peer router. The "standby 300 timers 1 110" command sets the hello timer to 1 second and the hold timer to 110 seconds for HSRP group 300.

cisco(config)#interface e0/2.22 cisco(config-subif)#standby ? <0-255> group number ... cisco(config-subif)#standby version 2 cisco(config-subif)#standby ? <0-4095> group number

A. The configuration bellow: standby version 2 standby 300 priority 110 standby 300 preempt

'preempt' is only needed on the higher HSRP priority router as the lowest HSRP priority router will only take over when the higher HSRP priority router is not available hence no need to preempt an existing HSRP router. The higher priority HSRP router will need to preempt the current HSRP router which has the lesser HSRP priority value.

A is correct

Question is tricky as there are multiple commands on the same row. Answer is correct

Want to mention that two of the answers are similar, one with a priority value of 110 and the other with a value of 90. By default, the priority value is 100; to make this one active (as per the intent of the question), this router must have a higher priority value than its peer (which is using the default of 100).

Group (instance) number 255 (max) is exceeded, thus, Device(config-if)# standby version 2
