New Release 300-410 CCNP Enterprise Questions

EIGRP does not have process ID as it uses Autonomous System (AS) numbers only.

This is not an authentication problem or we would see this error from the debug:

EIGRP: Ethernet0/0: ignored packet from 10.1.1.3, opcode = 1 (missing authentication or key-chain missing)

If the AS numbers between two routers are different then the neighbor relationship cannot be formed.
