What is another term for a demilitarized zone (DMZ)? - ✔✔Screened subnet is another
term for a demilitarized zone (DMZ). Two firewalls are used in this configuration: one
firewall resides between the public network and DMZ, and the other resides between
the DMZ and private network.
Screened subnet - ✔✔is another term for a demilitarized zone (DMZ). Two firewalls are
used in this configuration: one firewall resides between the public network and DMZ,
and the other resides between the DMZ and private network.
A screened host is - ✔✔a firewall that resides between the router that connects a
network to the Internet and the private network. The router acts as a screening device,
and the firewall is the screen host. This firewall employs two network cards and a single
screening router.
A dual-homed firewall is - ✔✔one that has two network interfaces: one interface
connects to the Internet, and the other connects to the private network. One of the most
common drawbacks to dual-homed firewalls is that internal routing may accidentally
become enabled.
APIPA - ✔✔?
Infrastructure mode - ✔✔allows wireless computers to connect to a LAN, a WAN, or the
Internet.
This means that infrastructure mode wireless computers can access all computers on
the LAN, WAN, and Internet.
Infrastructure mode is much more expensive to implement than ad hoc mode because
you must configure wireless access points.
While infrastructure mode is harder to set up and configure, it is much easier to manage
than ad hoc mode.
Ad hoc mode - ✔✔allows wireless computers to be configured much more quickly than
infrastructure mode.
computers all participate in the same network.
This means that the
wireless computers can access each other, but cannot access network resources on a
LAN, WAN, or Internet.
is much cheaper than infrastructure mode to implement.
In addition, it is easy to set up and configure and can provide better performance than
infrastructure mode.
However, it is difficult to manage.
Static IP addresses should not be implemented because the corporate network contains
a DHCP server. - ✔✔static IP
APIPA should not be used for the same reason. In addition, APIPA is utilized only if a
DHCP server is not found. - ✔✔APIPA
The Ethernet LAN technology does NOT use a multistation access unit (MAU) as its
central device - ✔✔The Ethernet LAN technology does NOT use a multistation access
unit (MAU) as its central device
Multi-station Access Unit (MAU) - ✔✔Central device in a Token Ring network which
passes the Token from device to device serially in order and in a one-way direction.
Token Ring supports - ✔✔full duplex transmission using carrier sense multiple access
with collision avoidance (CSMA/CA).
Ethernet LAN technology - ✔✔supports full duplex transmissions.
It uses carrier sense multiple access with collision detection (CSMA/CD).
It is defined by IEEE 802.3
Full-duplex can - ✔✔transmit and receive information in both directions simultaneously.
synchronous transmission has - ✔✔a start bit is used to indicate the beginning of
transmission.
The start bit is followed by data bits, and then one or two stop bits follow to indicate the
end of the transmission.
In synchronous transmission, - ✔✔the transmitter and receiver have synchronized
clocks and the data is sent in a continuous stream.
The clocks are synchronized by using transitions in the data and, therefore, start and
stop bits are not required for each unit of data sent
Half-duplex transmissions are - ✔✔transmissions in which information can be
transmitted in two directions, but only one direction at a time.
You should complete all of the following steps to protect against war-driving attacks: -
✔✔1. Change the default SSID.
2. Disable SSID broadcasts.
3. Configure the network to use
authenticated access only.f
4. Implement Wi-Fi Protected Access (WP
