What two option do we have to communicate OSPF Area-5 not directly connected to Area-0 (back bane area) to get routing updates from different areas?

all area must connected to area 0 so must create Virtual Link between area 5 and area 0 you should used Router ID in virtual link command   instead of interface IP address 

area 5 virtual-link <router IP address>

We can create Virtual Link.

By configuring the virtual link between area5 to area0

In area5 border router:-

using the command "area <trasnsit area number> virtual-link <router-ID of BDR of area5>"

In area0 border router:-

using the command "area <trasnsit area number> virtual-link <router-ID of BDR of area0> "

Right. virtual virtual link is one option .What other?

Creating a Virtual link between Area and Area0
