While the use of multiple "default router" commands IS a working solution,
it also involves the workstation deciding if/when to switchover and that is
not a fast failover solution. VRRP would be the primary choice (IMHO) for
transparent failover to the users, and the least interruption possible given
that HSRP is not allowed.

Subject: RE: DHCP Default Gateway
I would look at the question, does it state configure DHCP or VRRP or IRDP?
You said it states to configure DHCP only and have multiple gateways. This
can happen with DHCP so I would say that the answer is your second choice
rather than your first choice of VRRP.
That's just my opinion.

Subject: DHCP Default Gateway
I have a task that requires configuring a DHCP lease for a subnet.
There is a stipulation that for the default gateway, if R1 is down, then
R2 should be the default gateway. I am not allowed to use HSRP.
VRRP seems like a good solution, using the physical address of R1 as the
VRRP address for the DHCP pool.
ip dhcp pool pool1
default-router R1 (VRRP)
Would it also be acceptable to just to include a second address in the dhcp
pool such as
ip dhcp pool pool1
default-router R1 (x.x.x.x) R2 (x.x.x.x)
Thanks
