Drag each description on the left to the appropriate switch attack type on the right.
ARP spoofing/poisoning - The source device sends frames to the attacker's MAC address instead of to the correct device. Dynamic Trunking Protocol - Should be disabled on the switch's end user (access) ports before implementing the switch configuration in to the network. MAC flooding - Causes packets to fill up the forwarding table and consumes so much of the switch's memory that it enters a state called fail open mode. MAC spoofing - Can be used to hide the identity of the attacker's computer or impersonate another device on the network.

This means that the cable may not have been bad. It's time to check for issues in the Networking Closet. From the Networking Closet, check the switch to ensure that it's powered on.From the top left, select Floor 1 Overview.Under Networking Closet, select Hardware.Notice that the system light for the switch indicates that it is powered off. In addition, since the workstations in the Support Office and the Executive Office could not successfully ping the network, you can conclude that the device is turned off. Check to see if the switch has power.Above the rack, select Back to switch to the back view of the rack.Select the switch's power cable and verify that it is plugged into the UPS.Notice that the switch is plugged into the UPS, but it is not plugged into the critical load section. This means that if the main power goes off, the switch loses power as well.Move the switch's power cable from the non-critical load (Bank 2) outlet to the empty critical load (Bank 1) outlet.Notice that the Ethernet cables plugged into the server have link status lights that indicate they have power and a connection.Above the rack, select Front to switch to the front view of the rack.Observe the power light and activity lights for all ports on the switch.The lights are all on and active (except for the wireless access point, as it is still connected to the non-critical load (Bank 2) on the UPS) From the Executive Office, check for a network connection.From the top left, select Floor 1 Overview.Under Executive Office, select Hardware.Check for an active light on the computer's network card.The light is blinking, indicating a network connection.On the Exec monitor, select Click to view Windows 10.Right-click Start and select Settings.Select Network & Internet.The diagram in Status page shows a connection to the network and internet.(Optional) Ping each workstation on the network using their IP address.Each ping attempt now succeeds.

You manage a network with two switches. The switches are connected together through their Gigabit Ethernet uplink ports. You define VLAN 1 and VLAN 2 on each switch. A device on the first switch in VLAN 1 needs to communicate with a device on the second switch in VLAN 1. What should you configure to allow communication between these two devices through the switches?
Trunking
You have two switches connected together as shown in the following diagram. How many broadcast domains are in the network?
Two
You run a small network for your business that has a single router connected to the internet and a single switch. You keep sensitive documents on a computer that you would like to keep isolated from other computers on the network. Other hosts on the network should not be able to communicate with this computer through the switch, but you still need to access the network through the computer. Which of the following should you use in this situation?
VLAN
