  Refer to the exhibit.

  

  The junior network support staff provided the diagram as a recommended configuration for the first phase of a four-phase network expansion project. The entire network expansion will have over 1000 users on 14 network segments and has been allocated this IP address space:

  192.168.1.1 through 192.168.5.255

  192.168.100.1 through 192.168.100.255

  A. The AREA 1 IP address space is inadequate for the number of users.
  B. The AREA 3 IP address space is inadequate for the number of users.
  C. AREA 2 could use a mask of /25 to conserve IP address space.
  D. The network address space that is provided requires a single network-wide mask.
  E. The router-to-router connection is wasting address space.
  F. The broadcast domain in AREA 1 is too large for IP to function.
  A. The AREA 1 IP address space is inadequate for the number of users.
  C. AREA 2 could use a mask of /25 to conserve IP address space.
