Options
- AReplace the routers with newer models.
- BIncrease bandwidth capacity between the peers.
- CBreak down routing domain into multiple autonomous systems
- DImplement route summarization
- EUtilize authentication between the peers.

Explanation
EIGRP scalability issues typically stem from large routing tables and unbounded query propagation. (C) Segmenting the network into multiple EIGRP autonomous systems with redistribution at boundaries limits the EIGRP query domain-a runaway SIA (Stuck-In-Active) query cannot cross an AS boundary, preventing widespread outages. (D) Route summarization reduces the size of routing tables, limits the scope of topology changes, and constrains query propagation within summarized boundaries. Replacing hardware (A) does not address routing design flaws. Increasing bandwidth (B) reduces congestion but does not fix EIGRP scalability. Authentication (E) improves security but has no effect on scalability.
