• Question 106:

  Routers running OSPF and sharing a common segment become neighbors on that segment. What statement regarding OSPF neighbors is FALSE?

  A. The Primary and Secondary addresses on an interface allow the router to belong to different areas at the same time.
  B. All routers must agree on the stub area flag in the OSPF Hello Packets.
  C. Neighbors will fail to form an adjacency if their Hello and Dead intervals differ.
  D. Two routers will not become neighbors if the Area-ID and Authentication password do not match.
  A. The Primary and Secondary addresses on an interface allow the router to belong to different areas at the same time.

• Question 107:

  What is the major difference between multicast and unicast packet handling in RPR?

  A. They are sent via different Ring IDs.
  B. Multicast packets use source stripping.
  C. Multicast packets are sent highest priority.
  D. Only unicast packets are affected by the TTL parameter.
  B. Multicast packets use source stripping.

• Question 108:

  If two routers connected to the same Ethernet are configured to run HSRP (Hot Standby Router Protocol) in the same group number, which router's MAC address will be associated with the virtual IP address?

  A. It depends on which router is active.
  B. Neither- a virtual MAC address will be assigned based on the group number, unless the routers are configured to use their burned in addresses (BIAS).
  C. The routers will negotiate and decide automatically which MAC address to use based on the routers' IDs.
  D. Both routers' MAC addresses will be associated with the virtual IP address.
  E. Neither - the hosts will broadcast all traffic, which needs to travel ofF. segment.
  B. Neither- a virtual MAC address will be assigned based on the group number, unless the routers are configured to use their burned in addresses (BIAS).

• Question 109:

  C. It is an optional field in the ITU-T specification.
  D. It is present only in data frames sent through the network.
  B. It generally has significance only between the local switch and the DTE device.
