  • No router IDs are configured on the routers.
  • Authentication was not implemented between the routers.
  • The routers were not configured with the network command.
  • The routers are configured with the default priority.

Question 102

Which statement describes the load balancing behavior of EIGRP?
  • EIGRP for IPv6 supports unequal cost load balancing, but EIGRP for IPv4 does not.
  • EIGRP for IPv4 supports unequal cost load balancing, but EIGRP for IPv6 does not.
  • Neither EIGRP for IPv4 nor EIGRP for IPv6 support unequal cost load balancing.

Question 103

What is the purpose of the Cisco License Manager?
  • It is a free software application that helps network administrators rapidly deploy multiple Cisco software licenses across their networks.
