Network redundancy is designed to ensure that there are multiple paths available for data to travel between two points, so that if one path fails, the data can still be transmitted via an alternate path.

Spanning Tree Protocol is a network protocol that prevents loops in a network, not a type of network redundancy.

Active-active redundancy typically involves two devices that are both active and forwarding traffic.

Active-active redundancy provides improved fault tolerance because if one device fails, the other device can immediately take over without any interruption in service.

Network redundancy can increase the cost of a network due to the additional hardware and configuration required.

A mesh topology is a network topology in which each device is connected to every other device, creating multiple paths for data to travel.

Transmission Control Protocol (TCP) is a transport layer protocol, not a redundancy protocol.

Load balancing in network redundancy is used to distribute traffic across multiple paths, thereby improving network performance and reliability.

First-come, first-served is a scheduling algorithm, not a load balancing algorithm.

A router is a network device that is used to connect two or more networks and determine the best path for data to travel.

Spanning Tree Protocol is a network protocol that prevents loops in a network, not a type of router redundancy.

A spanning tree protocol is used in network redundancy to prevent loops in a network, which can cause network instability and outages.

VLAN Trunking Protocol (VTP) is a protocol used to manage VLANs, not a spanning tree protocol.

A switch is a network device that is used to connect multiple devices to a network and forward data between them.

Spanning Tree Protocol is a network protocol that prevents loops in a network, not a type of switch redundancy.
