No, summary routes will work just fine but not for the directly connected
area. For example, if the question says make sure sw2 and r6 can see each
others loopback as /24. This question does not say anything about any other
routers, then a summary is possible. The network statement under OSPF will
put it into OSPF but this will be as a /32. Then if you summarize this
network, it will be seen as a /24 in the other areas.

Is summary routes out of the questions also?
