Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 294

The maximum number of routers per OSPF area typically depends on which three factors? (Choose three.)

Answer options

• A. the kind of OSPF areas being implemented
• B. the number of external LSAs in the network
• C. the number of DRs and BDRs in the areas
• D. the number of virtual links in the areas
• E. how well the areas can be summarized

Correct answer: L, S, A

Explanation

The correct options reflect key aspects that determine OSPF scalability. The type of OSPF area affects routing behavior, the number of external LSAs can impact routing table size, and the roles of DRs and BDRs are critical for efficient multi-access network communication. Options that do not directly relate to the fundamental limitations of OSPF area design are incorrect.
