Based on the following partial output of the show ip ospf database command, which router roles(s) is Router7 performing? (Choose all that apply.)

• 300-410 : All Parts

Explanation:
Router7 is an area border router (ABR) and a backbone router (BR). The output reveals the link state databases for two areas, area 0 and area 2. Only ABR routers will display multiple databases when you execute this command.If Router7 is an ABR, then it is also connected to the backbone and will be a backbone router.Router 7 is not an autonomous system boundary router (ASBR) because it only displays sections in the output for Type 1 and Type 2 link-state advertisements (LSAs). ASBRs will also have a section for Type 4 LSAs, which would have its own heading at the end of the output.Router7 is not an internal router. A router is either an internal router or an ABR and Router 7 is an ABR.
