Which of the following areas of a network contains DNS servers and Web servers for Internet users?
A.
VPN
B.
MMZ
C.
DMZ
D.
VLAN
Explanation:
The DMZ is an IP network segment that contains resources available to Internet users such as Web
servers, FTP servers, e-mail servers, and DNS servers. DMZ provides a large enterprise network or
corporate network the ability to use the Internet while still maintaining its security.Answer D is incorrect. Virtual local area network (VLAN) is a virtual subnet that is created by
switches and supported routers that are VLAN enabled. VLAN is created by tagging the data frames
that a switch receives from hosts. Each port on the switch behaves in the same way as an IP subnet
and might require routing to communicate with hosts on other VLANs. VLANs can be used to isolate
hosts and segments and to control broadcast traffic.Answer A is incorrect. VPN stands for virtual private network. It allows users to use the Internet as a
secure pipeline to their corporate local area networks (LANs). Remote users can dial-in to any local
Internet Service Provider (ISP) and initiate a VPN session to connect to their corporate LAN over the
Internet. Companies using VPNs significantly reduce long-distance dial-up charges. VPNs also provide
remote employees with an inexpensive way of remaining connected to their company’s LAN for
extended periods.Answer B is incorrect. There is no area of a network such as MMZ.
