What action does an ABR take when it receives a type 1 LSA?

Ans: When the ABR receives a type 1 LSA, it builds a type 4 LSA and floods it to the bakbone, area 0.  Subsequent ABRs regenerate a type 4 LSA to flood it into their areas. There is only one type 4 LSA present in the R4 OSPF database. The type 4 LSA was generated by ABR R1 and describing the ASBR with the router ID 3.3.3.3.

Which type of LSA only exists on networks containing a DR?

Ans: Type 2 LSA exists on the networks containing a DR (designated router)

hat is the function of the OSPF LSR packet?

The Link State Request (LSR) packet is an OSPF packet Type 3. After DBD packets exchange process, the router may find it does not have an up-to-date database. The LSR packet is used to request pieces of neighbor database that is more up-to-date.
