The exam is results based. Unless there is language in a section that is restrictive, BOTH methods would be correct.

We have several ways to solve the same problem. But the point is how is that going to be looked at by the proctor in the real CCIE exam.

Area 78 cannot allow Type 5 LSA's, so that means it will be a stub area of some kind. Reading ahead to section 5.4 we notice that R8's interfaces may need to be added into OSPF via redistribution. So this would make Area 78 a Not-So-Stubby-Area (NSSA). > ? Alternatively, we could use the "ip ospf 1 area" command to add all of R8's interfaces to OSPF and leave Area 78 as a "stub" area with the "area 78 stub" command. In this example, I've accommodated both options and used "area 78 nssa" (mainly for those of you who redistributed to meet the objectives). This is the kind of situation where asking the proctor could be helpful I'd recommend asking whether they "require redistribution or the 'ip ospf area' command". If they specify one, do it - if they don't care go with what's easier for you. > > ..." > > Section 5.4 also states that all remaining connected networks should be redistributed into a routing protocol.
