In a WAN environment, switches connect multiple networks and facilitate communication between them.

BPDUs are used by STP to share information about the network topology and help in loop prevention.

The NAT table keeps track of active connections and their translations between private and public IP addresses, allowing NAT to function correctly.

The Root Bridge serves as a reference point for all path calculations in the STP topology.

An IPv6 address is 128 bits long, which allows for a significantly larger number of unique addresses compared to the 32-bit IPv4 address.

The TCP/IP protocol suite primarily operates at the Transport Layer, which is responsible for end-to-end communication and error recovery.

Wi-Fi operates at the Data Link Layer (Layer 2) of the OSI model, where it handles the framing and transmission of data over the wireless medium.

The Presentation Layer is responsible for data formatting, encryption, and decryption.

The Presentation Layer is responsible for data translation and encryption, ensuring that data is presented in a readable format.

TCP (Transmission Control Protocol) is used for reliable data transmission, providing error checking and guarantees delivery.

A port in the Forwarding state actively forwards traffic to and from the network.

MIMO (Multiple Input Multiple Output) technology allows multiple devices to connect to a single wireless access point by using multiple antennas to send and receive more data simultaneously.

A repeater is used to extend the range of a wireless network by receiving and retransmitting the wireless signal.

An IP address is used to identify a device on a network, while a MAC address identifies a device at the data link layer.

OSPF supports a hierarchical network topology, allowing for efficient routing and management of large networks through the use of areas.

OSPF uses a hierarchical network topology, which allows for efficient routing and management of large networks through the use of areas.

EIGRP (Enhanced Interior Gateway Routing Protocol) is classified as a hybrid routing protocol because it combines features of both distance vector and link state protocols.

Both IPv4 and IPv6 addressing schemes are commonly used in WANs for routing purposes, allowing for a large number of devices.

The command 'router eigrp [AS number]' is used to enter EIGRP configuration mode on a Cisco router.

A router is primarily responsible for routing traffic between VLANs, enabling communication between different network segments.

A router is typically used to perform Inter-VLAN routing, enabling communication between different VLANs.

802.11n can operate on both the 2.4 GHz and 5 GHz frequency bands, providing flexibility in network design.

Wi-Fi networks commonly operate on the 2.4 GHz and 5 GHz frequency bands, providing different ranges and speeds.

IEEE 802.1Q defines the VLAN tagging protocol, which allows for the identification of VLANs in Ethernet frames.

Both static and dynamic IP addressing are commonly used in WANs to accommodate various network configurations and requirements.

Multicast addresses in IPv6 are specifically designed for one-to-many communication, allowing a single packet to be sent to multiple destinations.
