Cisco 350-401 Online Questions & Answers

• Question 1371:

  An engineer receives a report that an application exhibits poor performance. On the switch where the server is connected, this syslog message is visible: SW_MATM-4-MACFLAP_NOTIF: Host 0054.3962.7651 in vlan 14 is flapping between

  port Gi1/0/1 and port Gi1/0/2.

  What is causing the problem?

  A. undesirable load-balancing configuration on the switch
  B. invalid port channel configuration on the switch
  C. wrong SFP+ and cable connected between the server and the switch
  D. failed NIC on the server
  B. invalid port channel configuration on the switch

  ---

  Explanation

  If the EtherChannel has not been established (for some misconfiguration), and the switch still treats the ports as individual ports while the other end is already using them as a bundle We have MAC flapping...

• Question 1374:

  What is the difference between a RIB and a FIB?

  A. The RIB is used to make IP source prefix-based switching decisions.
  B. The FIB is where all IP routing information is stored.
  C. The RIB maintains a mirror image of the FIB.
  D. The FIB is populated based on RIB content.
  D. The FIB is populated based on RIB content.

  Explanation

  CEF uses a Forwarding Information Base (FIB) to make IP destination prefix-based switching decisions. The FIB is conceptually similar to a routing table or information base. It maintains a mirror image of the forwarding information contained in the IP routing table. When routing or topology changes occur in the network, the IP routing table is updated, and those changes are reflected in the FIB. The FIB maintains next-hop address information based on the information in the IP routing table. Because there is a one-to-one correlation between FIB entries and routing table entries, the FIB contains all known routes and eliminates the need for route cache maintenance that is associated with earlier switching paths such as fast switching and optimum switching.

  Note: In order to view the Routing information base (RIB) table, use the "show ip route" command. To view the Forwarding Information Base (FIB), use the "show ip cef" command. RIB is in Control plane while FIB is in Data plane.
