A municipal hospital campus plans to add fifty volunteer-fire DMVPN spokes to existing hubs. What capacity concern should sizing review first?
Select an answer to reveal the explanation.
Short Explanation
Every new spoke is another IPsec conversation and another NHRP check-in at the hub. Size the hub’s CPU and crypto engine for that crowd before you celebrate the volunteer fleet.
Full Explanation
DMVPN hubs terminate many IPsec SAs and process NHRP registrations and resolutions proportional to spoke count and traffic patterns. Undersized CPU or crypto throughput causes flaps, slow registration, and data-plane loss as spokes scale. Spoke Internet BGP tables, campus STP timers, and VTP are not the primary hub-scaling limiters for this overlay growth.
