RJ11 as discussed before was widely used in analog telephony to connect the phone instrument and the cable.

* Diverse paths are network connections that use different physical routes or mediums to reach the same destination12.
* Diverse paths provide redundancy and fault tolerance in case of a network failure or outage, as traffic can be rerouted to an alternative path12.
* In this scenario, the company has a secondary connection to the same ISP, but it uses a different path than the primary connection, which is experiencing an outage12.
* Therefore, the traffic can continue to flow through the secondary connection, which is a diverse path12.
* Load balancing is a technique that distributes network traffic across multiple servers or links to optimize performance and availability12. Load balancing does not necessarily imply diverse paths, as the traffic may use the same or similar routes to reach the destination12.
* Multipathing is a technique that allows a device to use more than one path to communicate with another device, such as a server or a storage array12. Multipathing can improve performance, reliability, and load balancing, but it is not the same as diverse paths, as the paths may share some common segments or components12.
* Virtual Router Redundancy Protocol (VRRP) is a protocol that allows multiple routers to act as a single virtual router for a group of hosts on a network segment12. VRRP provides redundancy and failover for the default gateway, but it does not describe the configuration of the network connections between the routers and the ISP12. References:

* VLAN hopping is a type of network attack that allows an attacker to access network resources or traffic that belong to a different VLAN than the one the attacker is connected to12.
* VLAN hopping can be performed in two ways: switch spoofing or double tagging12.
* Switch spoofing is when an attacker configures their device to act as a trunk port and negotiates trunking with the switch, allowing the attacker to access all VLANs on the trunk link12.
* Double tagging is when an attacker sends a packet that contains two VLAN tags, one for the attacker's VLAN and one for the target VLAN. The first tag is stripped off by the switch, and the second tag is forwarded to the target VLAN, bypassing the VLAN isolation12.
* Double tagging is an example of an attack that utilizes a network packet that contains multiple network tags12.
* MAC flooding is a type of network attack that floods the switch's MAC address table with fake or spoofed MAC addresses, causing the switch to enter a fail-open mode and broadcast all traffic to all ports, allowing the attacker to capture or modify the traffic12. MAC flooding does not involve multiple network tags12.
* DNS spoofing is a type of network attack that alters the DNS records or responses to redirect the user to a malicious website or server, instead of the legitimate one12. DNS spoofing does not involve multiple network tags12.
* ARP poisoning is a type of network attack that sends fake or spoofed ARP messages to associate the attacker's MAC address with the IP address of another device, such as the gateway or the server, allowing the attacker to intercept or modify the traffic between the devices12. ARP poisoning does not involve multiple network tags12. References:
