With DHCP, if multiple default routers are provided, it is up to the host to
determine the availability of the gateway, and, if necessary, switch to the
next default. Depending on the hosts' functionality, it may not properly
determine the availability.
By configuring HSRP, you can remove the responsibility for determining
availability from the host, and let the routers do the work.

Subject: dhcp default-router vs hsrp [bcc][faked-from]
Importance: Low
Hi guys,
In IE lab 13, task 12.3, the requirement was to provide redundancy for dhcp
clients on a given lan segment -
"The default gateway for these hosts should be R6. If R6 is down, R3 should
be the default gateway."
My immediate thought was to use the dhcp command, default-router <R6's addr>
<R3's addr>.
But, the SG shows HSRP being configured instead.
My question is in the real lab, if there's a similar requirement, would
either
approach be acceptable?
I acknowledge that using hsrp is probably better for a couple of reasons -
faster switchover, works with all hosts - but
if I used the default-router command, is that wrong?
TIA, Tim
