The question asks about the least amount of equipment to segment two departments that have cables terminating in the same room.
Segmentation is the process of dividing a network into smaller logical units for security, performance, or management purposes.
One way to segment a network is by using VLANs (virtual LANs), which are logical groups of devices that share the same broadcast domain, regardless of their physical location or connection.
VLANs can be configured on switches that support Layer 2 or Layer 3 functionality. Layer 2 switches operate at the data link layer and forward frames based on MAC addresses. Layer 3 switches operate at the network layer and forward packets based on IP addresses.
A Layer 3 switch can perform both Layer 2 and Layer 3 functions, and can also route traffic between different VLANs without the need for an external router. This makes it a versatile and efficient device for network segmentation.
Therefore, the answer is C, a Layer 3 switch, as it can segment two departments with the least amount of equipment.

An AAAA record is a type of DNS record that maps a domain name to an IPv6 address. It is similar to an A record, which maps a domain name to an IPv4 address, but it uses a 128-bit address instead of a 32-bit one. An AAAA record allows a domain name to be resolved by both IPv4 and IPv6 clients, and it is necessary for accessing websites and services that use IPv6.

ping -t is an option for the ping command in Windows that allows the user to send continuous ping requests to a target until stopped by pressing Ctrl-C. This can help the technician run a constant ping command while testing various possible reasons for the connectivity issue. ping -w is an option for the ping command in Windows that allows the user to specify a timeout value in milliseconds for each ping request. ping -i is an option for the ping command in Linux that allows the user to specify the time interval in seconds between each ping request. ping -s is an option for the ping command in Linux that allows the user to specify the size of the data payload in bytes for each ping request.

The issue is that new employees are not able to print to the main networked copiers from their workstations after Switch 3 was added to the stack. Looking at the port configurations for Switch 3, we can see that the ports for printers (Ports 13-24) are shut down.
A . Enable the printer ports on Switch 3: This should be done because, as per the configuration shown in the image, these ports are currently shut down. Enabling them would restore connectivity for printing.
E . Reconfigure the VLAN on the printer ports on Switch 3: The VLAN for printers is set to 80 on Switch 3 while it is set to 60 on Switches 1 and 2. Changing VLAN of printer ports on Switch 3 to match with other switches (VLAN60) will ensure that they are all in the same broadcast domain and can communicate effectively.
The duplex settings do not need reconfiguration as they are already set to full duplex across all switches which facilitates efficient two-way communication.

BGP stands for Border Gateway Protocol and it is used to exchange routing information between autonomous systems (AS) on the Internet. A perimeter router is a router that connects an AS to another AS or to the Internet. Therefore, BGP is the best suited routing protocol for a perimeter router.
