1. What topology connects
Star Topology
each network device to a
central hub?
2. What is a short circuit? When electrical signals take a path other than the
intend-
ed path. In twisted pair wiring, a short means that
a signal sent on one wire might arrive on a
ditterent wire. CAUSES: worn wire jackets, crushed
wires that touch, and pierced wires that touch
metal.
3. What is CROSSTALK? Interference that is caused by signals within twisted
pairs
of wires.
4. What is attenuation? The loss of signal strencth from one end of a cable
to the
other caused by distance.
5. What is a split pair condition? A condition where a single wire in two ditterent
pairs is
reversed at both ends. EX: instead of matching
the green and green/white wires in pins 1 and 2,
you swap the solid green wire with the solid
brown wire.
6. What security improvements 1) Authentication for agents and managers
are added by SNMP v3?
2) Encryption of SNMP information
3) Message integrity to ensure that data is not
altered in transit
7. Must Class B addresses on all net- Yes. EX: Class B address is 130.15.0.0 the
other addresses

What networking device or NAT
ser- vice prevents the use of
IPsec in most cases?
10. What is a PACKET SNIFFER? Special software that captures (records) frames that
are
transmitted on a network.
11. How is a packet sniffer used? -To identify the types of traflc on a network
-To view the exchange of packets between
communicat- ing devices
-To analyze packets sent to and from specific
devices
-View packet contents
12. What is a port scanner used for? To identify protocol ports that are opened in a
firewall or
active on a device.
13. What does a port scanner check? It checksindividual systems
14. What is a throughput tester? It measures the amount of data that can be
transferred
through a network or processed by a device.
15. What is an Intrusion A special network device that can dtect attacks and
Detection System (IDS)?
sus- picious activity. Passive IDS monitors, logs,
and detects security breaches but takes not action to
stop attack. Ative IDS (Or Itrusion Protection
System IPS) performs funtions of an IDS and also
reacts when security breaches occur.
16. What is a TDR? Time Domain Reflector: A special device that
sends elec- trical pulses on a wire IOT discover
