cisco book page 951 given answer A is correct. Prevent indexes from shuffling: To prevent index shuffling and guarantee index persistence during reboots or minor software upgrades, use the snmp-server ifindex persist command, which shows up as snmp ifmib ifindex persist in the running configuration

A is correct

Must be A look a cisco toppic. https://community.cisco.com/t5/network-management/snmp-errors/td-p/672696

A is correct answer here is thew sample of real world solarwind snmp server deployment scripts SOLARWINDS NETFLOW SCRIPTS ! from the device’s global configuration mode ! call the int up int g0/0 ! capture inbound traffic ip flow ingress ! capture outbound traffic ip flow egress exit ! definite ip flow export source int ip flow-export source g0/0 ! definite ip flow version ip flow-export version 5 ! definite ip flow export destination ip flow-export destination 10.10.10.150 2055 ! set the flow time out ip flow-cache timeout active 1 ip flow-cache timeout inactive 15 snmp-server ifindex persist

In the following example, SNMP ifIndex persistence is enabled for Ethernet interface 3/1 only: router(config)# interface ethernet 3/1 router(config-if)# snmp ifindex persist router(config-if)# exit

R2(config)#snmp-server ifindex persist R2(config)# snmp-server ifindex permanent ^ % Invalid input detected at '^' marker. R2(config)#snmp ifindex permanent ^ % Invalid input detected at '^' marker. R2(config)#

Actually, I believe the answer is C. The KEY here in the question is KEY interfaces. The snmp-server ifindex persist enables for ALL interfaces. While snmp ifindex persist is a per interface application.

Correct answer is A. Period.

I tested the command at a Cisco 6500, Router(config)# snmp-server ifindex persist is correct When I give a snmp ?, I don't get the choise for "ifindex"

Router(config)# snmp-server ifindex persist https://www.cisco.com/c/en/us/support/docs/ip/simple-network-management-protocol-snmp/28420-ifIndex-Persistence.html

A is correct

from cisco press

Is correct ?

Correct Answer: snmp-server ifindex persist To globally enable SNMP ifIndex persistence, perform this task: router(config)# snmp-server ifindex persist To enable SNMP ifIndex persistence only on a specific interface, perform this task: Router(config-if)# snmp ifindex persist
