In which two situations would a company consider using an OSPF virtual link? (Choose two.)

  • when merging with another company and needing to connect the two backbone areas
  • when connecting discontiguous areas
  • when allowing corporate telecommuters to connect to corporate OSPF network resources
  • when importing a non-OSPF routing protocol into an ABR or backbone OSPF router
  • when importing a non-OSPF routing protocol into an internal OSPF router

Explanation: An OSPF virtual link is used to connect two areas through a non-backbone area. The virtual link is used to overcome the discontiguity of the OSPF domain caused by the non-backbone area. Therefore, it would be appropriate to use an OSPF virtual link in the following two situations:

  • When connecting discontiguous areas: If there are two OSPF areas that are not physically connected to each other, a virtual link can be created to connect them. The virtual link passes through a non-backbone area to reach the destination area.
  • When merging with another company and needing to connect the two backbone areas: If two companies merge, and each has its own OSPF backbone area, a virtual link can be created to connect the two backbone areas. This allows for a seamless integration of the two OSPF domains.

The other options listed in the question such as allowing corporate telecommuters to connect to corporate OSPF network resources, importing a non-OSPF routing protocol into an ABR or backbone OSPF router, and importing a non-OSPF routing protocol into an internal OSPF router are not relevant to the use case for OSPF virtual links.
