False
A modem running at 56 Kbps is actually running at 56 kilobaud.
False
A system's IPv6 link-local address is a multicast address.
False
Anycasting starts by giving a number of computers (or clusters of computers) unique IP addresses.
False
For IPv6 networks to function, they need common network IDs.
False
Multicast is a new idea introduced with IPv6.
False
Point Coordination Function (PCF) is the currently implemented collision avoidance system.
False
Setting up an IPv6 tunnel is easy.
False
To write IPv6 addresses containing strings of zeroes, you can use a pair of periods (..) to represent a string of consecutive groups with a value of zero.
False
Two nearby wireless access points (WAPs) should use close channels like 6 and 7.
False
Unfortunately, routing tables in IPv6 offer a much larger footprint than routing tables in IPv4.
False
With an omnidirectional antenna, the radio wave flows outward from the wireless access point (WAP) in one direction.
False
You can have more than two CSU/DSUs on a single T1 line.
False
What type of IPv6 address do you need to get on the Internet?
Global unicast address
What type of unit is formed by two or more wireless nodes communicating in ad hoc mode?
Independent Basic Service Set (IBSS)
Which protocol makes the IPv6 automation magic work?
Neighbor Discovery Protocol (NDP)
Which term represents a measurement of how well a wireless device is connecting to other devices?
Signal strength
__________ broadcasts data in small, discrete chunks over the different frequencies available within a certain frequency range.
Spread-spectrum
A DHCPv6 server is operating very similarly to an IPv4 DHCP server by passing out complete IPv6 information: addresses and default gateways, as well as items like DNS server addresses. In which mode is this server?
Stateful
A dedicated connection uses a dial-up connection to another private network or the Internet.
True
E1 and SONET use a derivative of the High-Level Data Link Control (HDLC) protocol as the control channel.
True
E1 and T1 lines can interconnect for international use.
True
Glass is notorious for bending radio waves as the waves pass through them causing refraction.
True
Lightweight EAP (LEAP) is a proprietary EAP authentication used almost exclusively by Cisco wireless products.
True
Most of the connections that make up the high-speed backbone of the Internet use technologies designed at least 20 years ago to support telephone calls.
True
One nice aspect of DSL is that you do not have to run new phone lines.
True
The 802.11 standard defines both how wireless devices communicate and how to secure that communication.
True
WAPs use an access control list (ACL) to enable or deny specific MAC addresses.
True
Whitelisting and blacklisting are labor-intensive processes, with whitelisting requiring far more work.
True
You can think of a link-local address as IPv6's equivalent to IPv4's APIPA/zeroconf address.
True
Which term refers to the first generation of packet-switching technology?
X.25
