Which action will resolve the adjacency issue?

  • A Configure the same autonomous system numbers.
  • B Match the hello interval timers.
  • C Match the authentication keys.
  • D Configure the same EIGRP process IDs.
Explanation

EIGRP routers that use authentication must have matching authentication parameters, including the key. A key mismatch causes EIGRP authentication to fail and prevents the neighbor relationship from forming. Hello timer values and locally configured EIGRP process IDs do not need to match for adjacency.
