  • Authentication will succeed and EIGRP updates can be exchanged.
  • Authentication will fail because the key chain names do not match.
  • Authentication will fail because the key chain names must match the router names.
  • Authentication will fail because only one key is configured.

Explanation: Authentication ensures that only authorized routers are eligible to become EIGRP neighbors. A precomputed password hash is encrypted by using a MD5 authentication and it is included with all EIGRP packets. The hash is computed using the key number and the key string. The receiving router decrypts the hash. If the passwords do not match for a packet, the routers will not become neighbors. In this scenario, the key number and the key string are the same on both routers. Therefore, they will become neighbors.
