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
What are three problems with this design? (Choose three.)
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 subnetwork, or subnet, is a logical, visible subdivision of an IP network.[1] The practice of dividing a network into two or more networks is called subnetting.
Computers that belong to a subnet are addressed with a common, identical, most-significant bit-group in their IP address. This results in the logical division of an IP address into two fields, a network or routing prefix and the rest field or host identifier. The rest field is an identifier for a specific host or network interface.
The routing prefix is expressed in CIDR notation. It is written as the first address of a network, followed by a slash character (/), and ending with the bit-length of the prefix. For example, 192.168.1.0/24 is the prefix of the Internet Protocol Version 4 network starting at the given address, having 24 bits allocated for the network prefix, and the remaining 8 bits reserved for host addressing. It defines the range 192.168.1.0 to 192.168.1.255; all connected devices with any of these addresses will belong to the same subnetwork. The IPv6 address specification 2001:db8::/32 is a large address block with 296 addresses, having a 32-bit routing prefix.
For IPv4, a network is also characterized by its subnet mask, which is the bitmask that when applied by a bitwise AND operation to any IP address in the network, yields the routing prefix. Subnet masks are also expressed in dot-decimal notation like an address. For example, 255.255.255.0 is the network mask for the 192.168.1.0/24 prefix.
Traffic is exchanged (routed) between subnetworks with special gateways (routers) when the routing prefixes of the source address and the destination address differ. A router constitutes the logical or physical boundary between the subnets.
The benefits of subnetting an existing network vary with each deployment scenario. In the address allocation architecture of the Internet using Classless Inter-Domain Routing (CIDR) and in large organizations, it is necessary to allocate address space efficiently. It may also enhance routing efficiency, or have advantages in network management when subnetworks are administratively controlled by different entities in a larger organization. Subnets may be arranged logically in a hierarchical architecture, partitioning an organization’s network address space into a tree-like routing structure.

Don’t need the direct connection between the two routers
