Which two statements describe OSPF? (Choose two.)
- OSPF must be implemented in a three-layer area hierarchy.
- OSPF routers may have large routing tables if routes are not summarized.
- OSPF uses the SPF algorithm, which requires few CPU cycles.
- OSPF routers within an area have the same link-state information.
- OSPF performs automatic route summarization by default.
Explanation: OSPF routers within the same area will have the same link-state databases. Without route summarization, OSPF routers may have large routing tables. There is no automatic summarization of routes with OSPF. OSPF can be implemented in a single area or in a two-layer multiarea hierarchy. SPF recalculation, especially in larger networks, is processor intensive.
