IP Addressing

Question 1

What allows to determine which network segment an IP address belongs to?
Physical address
Dynamic Host Configuration Protocol (DHCP)
Address Resolution Protocol (ARP)
Subnet mask

Answer 1

Subnet Mask

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs.

Question 2

In a network using subnets, the term “Default gateway” refers to a network device that enables exchange of data between hosts residing in different subnets.

Question 16

Automatic Private IP Addressing (APIPA) allows a Windows host to self-configure an IPv4 address and subnet mask when Dynamic Host Configuration Protocol (DHCP) is unavailable. APIPA uses an address block range between 169.254.0.0 and 169.254.255.255. APIPA-assigned addresses are valid only for communications within a network segment that a given host is connected to (a host with APIPA-assigned address cannot connect to the Internet).
True
