Refer to the exhibit. An engineer attempts to configure standby group 512 on interface GigabitEthernet0/1, but the configuration is not accepted. Which command resolves this problem?
The correct answer is D. standby version 2. The configuration for HSRP group 512 is rejected because it falls outside the group number range supported by HSRPv1, requiring HSRPv2 to be explicitly enabled on the interface.

Why each option
The configuration for HSRP group 512 is rejected because it falls outside the group number range supported by HSRPv1, requiring HSRPv2 to be explicitly enabled on the interface.
The `standby redirects` command is used for ICMP redirect messages and does not address issues with unsupported HSRP group numbers.
The `standby 512 priority 100` command sets the priority for the specified group but will only be accepted after the HSRP group number issue is resolved by enabling HSRPv2.
The `standby 512 preempt` command enables preemption for the specified group, but cannot be configured until HSRPv2 is enabled to support the group number 512.
The command `standby version 2` enables HSRP Version 2, which supports group numbers from 0 to 4095, thereby allowing the configuration of `standby group 512` which is not supported by the default HSRPv1 range of 0-255.
