Networking Fundamentals - Part 2

Subnetting makes the network more efficient by dividing the network into smaller, interconnected networks which helps to minimize network traffic.

• True

• False

How many bits would the network portion need to “borrow” from the host portion in order to create 16 new sub-networks?

• 1 host bits

• 2 host bits

• 4 host bits

• 3 host bits

Complete the sentence. An IPv4 address consists of _____

• 64 bits divided into four blocks.

• 128 bits divided into eight blocks.

• 32 bits divided into four octets.

• 64 bits divided into eight octets.

What best describes Variable Length Subnet Mask (VLSM)?

• A method for assigning IP addresses to devices that allow different subnets to have different subnet masks depending on their size.

• A way of creating multiple VLANs on a single switch to improve network security.

• A technique for assigning IP addresses that uses a fixed-length subnet mask to simplify network design.

• A technique for optimizing routing tables by summarizing multiple subnets into a single network address.

What is a limitation of the IPv4 address space?

• The maximum size of an IPv4 address is 32 bits, which limits the number of unique addresses that can be assigned.

• IPv4 addresses are not compatible with modern networking protocols.

• IPv4 addresses are difficult to remember and prone to typographical errors.

• IPv4 addresses are not hierarchical, which can make routing inefficient and slow.

Which statement best describes how IP addresses and subnet masks work together?

• An IP address and subnet mask work independently and do not have any relationship with each other.

• An IP address and subnet mask are interchangeable terms used to identify a device on a network.

• An IP address is used to identify a device on a network, while a subnet mask is used to determine the physical location of the device.

• An IP address and subnet mask work together to determine the network and host portions of an IP address.

What is the best definition for Classless Inter-Domain Routing (CIDR) notation?

• CIDR is a strategy used to separate the physical devices within a network infrastructure.

• CIDR is a method by which a network is subnetted, and the subnets are then subnetted further.

• CIDR is a method that allows an IP address to use any subnet mask, regardless of predefined classes.

• CIDR is a class-based system that uses different ranges of bits for subnets.

What definition best describes "binary"?

• A numbering system with a base of 2, using digits 0 and 1.

• A numbering system with a base of 16, using digits 0-9 and letters A-F.

• A numbering system with a base of 48, using digits and special characters.

• A numbering system with a base of 10, using digits 0-9.

Which statement represents the binary equivalent of the hexadecimal number AF?

• 00001011

• 00101111

• 11111000

• 10101111

What is an advantage of using hexadecimal over binary?

• Hexadecimal numbers are easier to convert to decimal than binary numbers.

• Hexadecimal numbers take up less memory than binary numbers.

• Hexadecimal notation allows for a more compact representation of binary data.

• Hexadecimal numbers are easier to understand than binary numbers.
