Chapter 1 Revision Mastering IP Addressing Concepts

Which of the following is the correct subnet mask for a network that requires exactly 30 usable host addresses?

• 255.255.255.224

• 255.255.255.240

• 255.255.255.248

• 255.255.255.252

What does VLSM stand for in the context of IP addressing?

• Variable Length Subnet Mask

• Virtual Local Subnet Mask

• Variable Logical Subnet Mask

• Virtual Length Subnet Mask

Which of the following is a valid public IPv4 address?

• 10.0.0.1

• 172.16.5.4

• 192.168.1.100

• 8.8.8.8

Which of the following is NOT a difference between IPv4 and IPv6?

• IPv6 addresses are 128 bits long, while IPv4 addresses are 32 bits long.

• IPv6 uses hexadecimal notation, while IPv4 uses decimal.

• IPv6 supports broadcast communication, while IPv4 does not.

• IPv6 has a much larger address space than IPv4.

What is the CIDR notation for the subnet mask 255.255.255.192?

• /24

• /25

• /26

• /27

Which of the following is a private IP address range?

• 11.0.0.0 – 11.255.255.255

• 172.16.0.0 – 172.31.255.255

• 192.0.2.0 – 192.0.2.255

• 224.0.0.0 – 239.255.255.255

How many usable host addresses are available in a /29 subnet?

• 6

• 8

• 14

• 30

Which protocol is commonly used for dynamic IP address allocation in a network?

• DNS

• DHCP

• FTP

• SNMP

Which of the following routing protocols is classified as a distance vector protocol?

• OSPF

• EIGRP

• RIP

• IS-IS

What is the main advantage of using CIDR over traditional classful addressing?

• It increases the number of available IP addresses.

• It allows for more efficient use of IP address space.

• It eliminates the need for subnetting.

• It supports only IPv6.
