Q

Manages the assignment of IP addresses on the internet.

A

The Internet Assigned Numbers Authority (IANA)

19
Q

In the subnet mask: The 0’s identify

A

Host ID

20
Q

Each IP class has a reserved range for private IP addresses. This is due to the following two factors:

A

Each IP address on any network, including the internet, must be unique.
There is a finite number of IP addresses using IPv4.

21
Q

This special address is also known as home or localhost. This address is reserved by each network interface card (NIC) and is used for testing purposes.

A

Loopback
127.0.0.1

22
Q

Breaking a network into smaller networks (subnetting) provides some benefits including:

A

Increased security
Easier network management
Improved network performance
Separation of departments

23
Q

Supernetting has many advantages including:

A

Reducing the size of routing tables.
Simplifying the network overview.
Decreasing CPU and RAM resources on the routers.
Improving network performance.

24
Q

With this method of addressing, you manually configure IP information on each host.

A

Static addressing

25
Q

Static addressing is best used in the following situations:

A

Networks with a small number of hosts.
Networks that do not change devices often.
Devices that must always have the same address (e.g., servers, printers, and routers). You assign permanent IP addresses to these devices.

26
Q

The Windows function that provides DHCP autoconfiguration addressing.

A

Automatic Private IP Addressing

27
Q

A protocol used to centrally manage the distribution of IP addresses within a network.

A

Dynamic Host Configuration Protocol

28
Q

A system that translates domain names into IP addresses, which computers can understand.

A

Domain Name System
(DNS)

29
Q

A command that sends an ICMP echo request/reply packet to a remote host. A response from the remote host indicates that both hosts are correctly configured and a connection exists between them.

A

Ping

30
Q

A protocol that hosts use to discover the MAC address of a device.

A

Address Resolution Protocol
(ARP)

31
Q

Defines the range of IP addresses that the DHCP server can assign.

A

IP range

32
Q

Defines the network ID and host ID.

A

Subnet mask

33
Q

Identifies the IP addresses that the DHCP server will not assign.

A

IP exclusions

34
Q

Are static IP addresses that are not dynamically assigned by the DHCP server.

A

IP reservations

35
Q

Specifies the amount of time a DHCP lease is valid.

A

DHCP lease time

36
Q

Defines the router that data packets leaving the network are sent to.

A

Default gateway
