The maximum length of a standard Ethernet cable (Cat 5e or Cat 6) is 100 meters for effective WAN connections.

The maximum length of a TCP segment is 65,535 bytes, which includes both the header and the data.

A Class C network with a default subnet mask of 255.255.255.0 can be subnetted into 8 subnets by borrowing 3 bits from the host portion.

IPv6 can theoretically support approximately 340 undecillion unique addresses due to its 128-bit address space.

The 802.1Q standard allows for a maximum of 4096 VLANs to be created on a switch.

The 802.1Q standard allows for the creation of up to 4096 VLANs, as it uses a 12-bit VLAN ID.

A typical Wi-Fi network can reach up to 100 meters in open space, although this can vary based on environmental factors and the specific technology used.

The multicast address range in IPv6 is defined as FF00::/8, which is used for multicast communication.

Fiber optic cables provide higher bandwidth and can transmit data over longer distances compared to other media, making them ideal for WANs.

VLANs reduce broadcast traffic by segmenting a network into smaller, isolated groups, which improves overall network performance.

VLSM allows for subnets of different sizes, which helps to reduce IP address wastage by allocating only as many addresses as needed for each subnet.

A router's primary function is to forward packets between different networks, determining the best path for data.

A router's primary function in a WAN is to route packets between different networks, enabling communication across the WAN.

A router's primary function is to forward data packets between different networks, directing traffic efficiently.

In a WAN, a switch primarily connects multiple networks and manages data traffic between them.

A wireless access point connects wired devices to a wireless network, allowing them to communicate with wireless clients.

Error control in WANs is primarily focused on ensuring data integrity during transmission by detecting and correcting errors.

The primary function of the Transport layer is to provide reliable or unreliable delivery of data, depending on the protocol used.

EIGRP primarily uses bandwidth as its metric, but it also considers delay, load, and reliability to calculate the best path.

A firewall is used to filter incoming and outgoing traffic based on predetermined security rules.

A firewall is used to filter incoming and outgoing traffic based on predetermined security rules.

The primary purpose of error control in wireless communication is to ensure data integrity by detecting and correcting errors that may occur during transmission.

IP routing is primarily used to determine the best path for data packets to travel across networks.

IPv6 was developed to address the limitations of IPv4, particularly the exhaustion of available IP addresses, by providing a vastly larger address space.

IPv6 was developed to address the limitations of IPv4, particularly the exhaustion of available IP addresses, by providing a vastly larger address space.

NAT allows multiple devices on a local network to share a single public IP address, which helps conserve the limited number of available public IP addresses.

STP is designed to prevent loops in a network by creating a loop-free logical topology.

The TCP/IP model provides a framework for network communication, allowing different devices to communicate over the internet.

In a WAN, switches connect multiple networks and facilitate communication between them, although they primarily operate at the Data Link Layer.
