19
Q

_____ is used to run in plenum space, typically above a drop ceiling. This special type of cable helps reduce the chemicals that may burn during a fire.

A

Plenum Cable

20
Q

______ is used in standard network cabling as a jacket for the cables.

A

Polyvinyl Chloride (PVC)

21
Q

______ allows you to use the wires in the cabling for more than one device. This is not recommended. It reduces signal quality.

A

Splitters

22
Q

______ is used for longer cable runs, typically for the service providing company for carrying Internet or digital applications.

A

RG-6

23
Q

______ is used by service providers for shorter cable runs, typically its found inside of buildings. It is not intended to carry ethernet traffic since it has an impedance of 75 ohms.

A

RG-59

24
Q

_____ is a 32-bit address used for IP communication. Its address is separated into 4 octets, with 1 to 3 numbers in each octet.

A

IPv4

25
Q

_____ is a 128-bit address used for IP communication. It was the result of an overhaul to IPv4, as the depletion of IP addresses began to become a concern. It created 340 undecillion unique addresses.

A

IPv6

26
Q

_____ is an address that is routable and reachable on the internet. This is typically used in WAN applications to communicate across a service provider’s backbone.

A

A public address

27
Q

____ is an address that is not routable via the internet, and is used only for local communication within a LAN. An ISP will block private IP addresses to/from the internet. These are defined in RFC 1918 for further research.

A

A private address

28
Q

____ is a Microsoft developed protocol which assigns you an IP address within a reserved, private class when you have failed to receive an IP address from a Dynamic Host Configuration Protocol (DHCP) server. This address will always begin with 169.254.

A

APIPA Automatic Private IP Addressing

29
Q

____ is an address that is put in manually by a user or administrator. It is often used in smaller or niche environments that don’t use dynamic addressing.

A

A Static Address

30
Q

_____ is an address that is automatically assigned, typically by a router or DHCP server. This is typically used in larger environments with lots of nodes.

A

A dynamic address
