Which of the cabling types listed below provide(s) protection against an outside signal interference? (Select all that apply)

Coaxial


Fiber-optic


STP

One of the differences between the UTP and STP cabling is that the STP cable takes advantage of additional protective cover reducing signal interference from outside sources.
True
In twisted-pair cabling wires are grouped into pairs and wires in each pair are twisted around each other in order to reduce:
Cross-talk
What is the typical cable segment length for a copper twisted-pair Ethernet cable?
100 meters
Category 3 (CAT3) cable is a 10 Mbps twisted-pair copper cable used in telephone wiring.
True
Which of the following twisted-pair copper cabling types is most commonly used in modern Ethernet networks?
CAT5e
What is the maximum cable segment length for a CAT5e cable?
100 meters
Which of the answers listed below refer(s) to the characteristics of a Category 5e (CAT5e) cabling? (Select all that apply)

Twisted-pair cabling


RJ-45 connector


Copper cabling


1 Gbps Ethernet

What is the minimum cabling requirement for a 10 Gbps connection over copper twisted-pair?
CAT6
The Category 6 (CAT6) cabling supports 10 Gbps data transfer rate at a limited range of up to 55 meters, whereas CAT6A (Augmented) cabling allows for 10 Gbps data transfer rate over a standard cable segment length of 100 meters.
True
The term "Plenum" refers to an enclosed space used for airflow, such as the one between dropped ceiling and structural ceiling in a building. Cabling coated with a fire-retardant jacket placed in this space is referred to as plenum-rated cabling. Plenum-rated cabling must meet special requirements so that it doesn't catch on fire easily.
True
Materials from which the plenum-rated cable's cover is made include: (Select 2 answers)

PVC


FEP

Which of the following answers list examples of coaxial cabling types? (Select 2 answers)

RG-59


RG-6

Which of the terms listed below refers to a loss in signal strength during transmission caused by increasing distance and obstacles encountered on the signal path?
Attenuation
What is the bit length of an IPv4 address?
32 bits
Which of the following answers refer to the characteristic features of the 10.0.0.0 - 10.255.255.255 IPv4 address space? (Select 2 answers)

Class A range


Non-routable (private) IP address range

Which of the answers listed below refer to the 172.16.0.0 - 172.31.255.255 IPv4 address space? (Select 2 answers)

Class B range


Non-routable (private) IP address range

What are the characteristic features of the 192.168.0.0 - 192.168.255.255 IP address space? (Select 2 answers)

Non-routable (private) IP address range


Class C range

An IPv4 address in the range 169.254.0.1 through 169.254.255.254 indicates problem with what type of service?
DHCP
An IPv6 address consists of:
128 bits
IPv6 addresses are expressed with the use of:
Hexadecimal numbers
A double colon in an IPv6 address indicates that part of the address containing only zeroes has been compressed to make the address notation shorter.
True
Which of the following answers refers to an IPv6 link-local address?
FE80::/64
An IP address assigned permanently to a computer by an Internet Service Provider (ISP) is known as:
Static IP address
A system containing mappings of domain names to various types of data, such as for example numerical IP addresses is known as:
DNS
