What are the influencing factors that can impact EIGRP scalability over DMVPN? (Choose two.)
The correct answer is A. Number of peers C. Number of prefixes. EIGRP scalability over DMVPN is primarily impacted by (A) the number of peers and (C) the number of prefixes. More spoke peers means more EIGRP neighbor relationships for the hub to maintain, more hello/update/query traffic, and greater processing demand. A larger number of…

Explanation
EIGRP scalability over DMVPN is primarily impacted by (A) the number of peers and (C) the number of prefixes. More spoke peers means more EIGRP neighbor relationships for the hub to maintain, more hello/update/query traffic, and greater processing demand. A larger number of prefixes increases the size of topology tables, EIGRP updates, and query propagation scope. Encryption type (B) affects CPU load but is not an EIGRP-specific scalability factor. Number of users (D) is a traffic concern, not a routing protocol scalability factor. WAN bandwidth at spokes (E) affects throughput but does not directly limit EIGRP's ability to scale.
