BSCI Chapter 7 Q&A Clarification?

[FONT=&quot]11.[FONT=&quot] [/FONT][/FONT][FONT=&quot]What issues may emerge when running OSPF within an area containing a Frame Relay NBMA cloud?[/FONT]

Answer: Having a Frame Relay NBMA cloud within one OSPF area causes summary LSAs to be flooded throughout the NBMA network. This results in a large number of routers recalculating whenever there is a change that requires the topology table to be updated, and the Frame Relay cloud can become saturated. If the Frame Relay cloud has a problem, the entire network could suffer.

Ok.. I thought summary LSA's were only send BETWEEN areas.. Any ideas?

Summary LSAs are generated at the ABR and flooded throughout an area.In the case you mentioned the ABR can have a FR interface connected to other router within the area.
