A company is implementing a dynamic host configuration protocol (DHCP). Given that the following conditions exist, which represents the GREATEST concern?
A.
Most employees use laptops.
B.
A packet filtering firewall is used.
C.
The IP address space is smaller than the number of PCs.
D.
Access to a network port is not restricted.
Explanation:
Given physical access to a port, anyone can connect to the internal network. The other choices do not present the exposure that access to a port does. DHCP provides convenience (an advantage) to the laptop users. Sharing IP addresses and the existence of a firewall can be security measures.
