MP and Neighbor command do not have the same function. As well, do a univercd search on neighbor command and how it can be used for cost assignments in certain scenarios. I think you will walk away with a better understanding of this general subject once you put a few minutes of contrast and comparison of the subject to the test.
See the following list of different ospf network types and how they differ.
You will see essentially the neighbor command is used in an environment where unicast hello packets are must be sent, and the neighbor command accommodates specifying the interface of the neighbor which you will be sending these unicast packets. I would also recommend labbing these varios network types up at your earliest opportunity. You really need to understand the nature of how these network types can be manipulated as well as the variations of neighbor relationships that can be built.
I hope this leads you to some great learning.

point-to-point:
Hello: multicast 224.0.0.5 LSA: multicast 224.0.0.5 Hello Interval: 10 Dead Interval: 40 DR/BDR Election: none
point-to-multipoint:
Hello: multicast 224.0.0.5 LSA: unicast Hello Interval: 30 Dead Interval: 120 DR/BDR Election: none
Broadcast:
Hello: multicast 224.0.0.5 LSA: multicast 224.0.0.5 and 224.0.0.6 Hello Interval: 10 Dead Interval: 40 DR/BDR Election: yes
nbma (non-broadcast):
Hello: unicast LSA: unicast Hello Interval: 30 Dead Interval: 120 DR/BDR Election: yes
Neighbor statement is required to form adjacencies.
virtual-link:
Hello: unicast LSA: unicast Hello Interval: 10 Dead Interval: 40 DR/BDR Election: no
No neighbor statement necessary. This is implied within the command to create the virtual link. Area x virtual-link a.b.c.d where a.b.c.d is the 32 bit ospf router-id, expressed in dotted decimal notation. Treated as an ospf demand circuit, and point-to-point characteristics.

Group,
As I understand OSPF point to multipoint and neighbour command both have same function in Hub and spoke topolgy. If task doesn’t specify what to use , can we use any on one ?
Thanks
