Hi Diptish,
Personally, I think it's not a good idea to assume the existence of
requirements that aren't explicitly stated. If the lab doesn't require that
connectivity be maintained if a link fails, I wouldn't assume there's an
implicit requirement for that.
Of course, if in doubt, ask the proctor.
On the other hand, don't assume either that the lab will explicitly tell you
to use a certain feature to achieve a certain function or result. There
very well might be a requirement for hsrp, NAT or irpd or something else but
the lab won't tell you to implement any of those things. It will just say
what result is required and leave it to you to figure out how such a result
is achieved.
HTH, Tim
