Refer to the exhibit. What statement is true of the configuration for this network?

Question

Options

• AThe configuration that is shown provides inadequate outside address space for translation of the number of inside addresses that are supported.
• BBecause of the addressing on interface FastEthernet0/1, the Serial0/0 interface address will not support the NAT configuration as shown.
• CThe number 1 referred to in the ip nat inside source command references access-list number 1.
• DExternalRouter must be configured with static routes to networks 172.16.1.0/24 and 172.16.2.0/24.

• A
  6% (1)
• C
  81% (13)
• D

Explanation

In the command 'ip nat inside source list 1 interface Serial0/0 overload', the number 1 refers to ACL number 1, which defines the inside local addresses eligible for translation. This is a standard NAT overload (PAT) configuration where the ACL identifies which internal hosts will have their addresses translated. Option A is incorrect because PAT (overload) allows many inside addresses to share a single outside IP. Option B is incorrect because the FastEthernet0/1 addressing does not invalidate the Serial0/0 NAT config. Option D is incorrect because ExternalRouter only needs a route back to the NAT outside interface, not to the internal subnets individually.
