• Question 561:

  Which of the following commands configures an SNMP host to authenticate a user by username and send clear text notifications, the receipt of which will be acknowledged by the receiver?

  A. Router(config)# snmp-server host 192.168.5.5 informs version 3 noauth CISCO
  B. Router(config)# snmp-server host 192.168.5.5 traps version 3 auth CISCO
  C. Router(config)# snmp-server host 192.168.5.5 informs version 2c CISCO
  D. Router(config)# snmp-server host 192.168.5.5 informs version 3 authpriv CISCO
  A. Router(config)# snmp-server host 192.168.5.5 informs version 3 noauth CISCO

  ---

  The command snmp-server host 192.168.5.5 informs version 3 noauth CISCO will configure the host to authenticate a user by username and send clear text notifications. The receiver will then acknowledge receipt of the notification. The keyword informs indicates that an inform message type will be used. Unlike a trap, an inform message is acknowledged by the receiver.

  The version 3 keyword indicates that version 3 is in use, which is the ONLY version that supports authentication and encryption. Finally, the noauth keyword specifies authentication by username only and no encryption.

  The command snmp-server host 192.168.5.5 traps version 3 auth CISCO configures the host to send traps rather than informs.

  The command snmp-server host 192.168.5.5 informs version 2c CISCO specifies version 2c, which only support community string-based authentication.

  The command snmp-server host 192.168.5.5 informs version 3 authpriv CISCO specifies the keyword authpriv, which indicates encryption will be used and authentication based on HMAC-MD5 or HMAC-SHA algorithms.

  Objective:

  Infrastructure Services

  From the output of the "show ip eigrp topology ..." command, we notice network 192.168.13.0/24

  was learned via two routes:+ From 192.168.23.3 (R3) with FD = 1075200 and AD = 281600+ From 192.168.12.1 (R1) with FD = 2611200 and AD = 281600 From the output of the "show ip route ..." command, we learned that the best (and chosen) path is via 192.168.23.3 (R3).

  To use both paths (called unequal cost load balancing) with EIGRP, the second path via R1 must satisfy the feasibility condition. The feasibility condition states that, theAdvertised Distance (AD) of a route must be lower than the feasible distance of the current successor route.

  In this case, the second path satisfies the feasible condition as its AD (281600) is smaller than the FD (1075200) of the best path. Therefore we can configure loadbalancing with "variance" command. In other words, EIGRP will install all paths with metric < variance * best_metric into the local routing table, provided that it meets the feasibility condition to preventrouting loop. Therefore we can calculate the variance > metric / best_metric = 2611200 / 1075200 =2.4.

  So with a variance greater than 2 (and must be an integer), we can load balance traffic to network 192.168.13.0/24.
