Q1Domain Verified
In the context of IPv4 subnetting, what is the primary advantage of using a /24 subnet mask over a /23 subnet mask for a small, isolated network that requires 100 unique IP addresses?
A /24 mask conserves IP addresses by reducing the number of usable hosts per subnet.
A /24 mask provides a smaller broadcast domain, enhancing network security and performance.
A /23 mask is more complex to configure, leading to fewer misconfigurations.
A /23 mask allows for more broadcast addresses, improving network efficiency.

When migrating from a classful addressing scheme to CIDR, a network administrator is presented with the IP address 192.168.10.0. What is the most efficient CIDR block that can accommodate at least 200 hosts while maintaining the 192.168.10.0 network address?
192.168.10.0/23
192.168.10.0/22
192.168.10.0/25
192.168.10.0/24

Question: In the context of IPv4 subnetting, what is the primary characteristic that defines the boundary between the network portion and the host portion of an IP address, and how does the subnet mask facilitate this division
The broadcast address, used for sending packets to all hosts on a subnet, dictates the separation.
The default gateway, which directs traffic to different networks, determines the network and host portions.
The class of the IP address (A, B, or C) inherently defines the network and host portions, making the subnet mask redundant.
The subnet mask, a 32-bit number with contiguous '1's followed by contiguous '0's, logically ANDed with the IP address, isolates the network and host portions.
