Quiz 5C: Configure IP Networks and Subnets

What is the primary function of a subnet mask?

• To define the number of available IP addresses in a subnet

• To identify the first octet of an IP address

• To specify the network portion of an IP address

• To allocate IP addresses to hosts dynamically

How does a VLAN address the issue of excessive broadcast traffic in a network?

• By assigning unique IP addresses to each host

• By dividing the network into separate broadcast domains

• By increasing the bandwidth of network connections

• By implementing network address translation (NAT)

What is the primary goal of subnet calculations?

• To identify the first octet of an IP address

• To determine the number of bits needed for subnetting

• To allocate IP addresses dynamically using DHCP

• To divide a network into smaller, manageable subnetworks

What is the purpose of Automatic Private IP Addressing (APIPA)?

• To allocate public IP addresses to hosts dynamically

• To assign private IP addresses to hosts automatically

• To enable communication between hosts on different subnets

• To allow hosts to communicate even when DHCP is unavailable

How many bits are borrowed for subnetting in a /28 subnet mask?

• 4

• 8

• 16

• 32

What range of IP addresses belongs to Class A networks?

• 1.0.0.0 to 127.255.255.255

• 128.0.0.0 to 191.255.255.255

• 192.0.0.0 to 223.255.255.255

• 224.0.0.0 to 239.255.255.255

How does classful addressing allocate network IDs?

• Based on the subnet mask

• Based on the first octet of the IP address

• Based on the default gateway configuration

• Based on the number of hosts in the network

What does the term 'classless addressing' refer to?

• Assigning IP addresses based on classes A, B, or C

• Using subnet masks to identify network IDs

• Allocating IP addresses dynamically using DHCP

• Reserving specific IP address ranges for private use

What is the primary purpose of subnetting in networking?

• To increase the number of available IP addresses

• To divide networks into smaller segments for performance and security

• To allocate IP addresses to hosts dynamically

• To establish connections between different VLANs

In a subnetting scheme, what does each power of 2 represent?

• The number of available subnets

• The number of bits needed for host IDs

• The number of bits needed for subnetting

• The number of available IP addresses
