Refer to the exhibit. All routers in this network are configured to run OSPF on all interfaces. If you examine the OSPF database on R4, in which LSA will you find 10.1.5.0/24?

Type 2 Network LSAs are generated by the Designated Router (DR) on a multi-access segment and describe the routers attached to that segment - they do not carry subnet prefix information from other areas.

R3 functions as an Area Border Router (ABR) sitting between the area containing 10.1.5.0/24 and R4's area. ABRs generate Type 3 Summary LSAs to advertise prefixes from one area into another. R4, being in a different area, would see 10.1.5.0/24 only in R3's Type 3 Summary LSA and not in any intra-area LSA type.

Being in different areas does not prevent a prefix from appearing in the OSPF database on R4 - ABRs specifically exist to distribute inter-area routing information via Type 3 LSAs.

Type 1 Router LSAs are flooded only within the originating area and are never forwarded across area boundaries, so R4 in a different area would never see R3's Type 1 LSA.
