Why would a threat actor launch a MAC address overflow attack on a small network?

To capture frames destined for other LAN devices

To ensure legitimate hosts cannot forward traffic

To overwhelm the switch and drop frames

Which is an example of a DHCP starvation attack?

A threat actor leases all the available IP addresses on a subnet to deny legitimate clients DHCP resources.

A threat actor changes the MAC address of the threat actor’s device to the MAC address of the default gateway.

A threat actor configures a host with the 802.1Q protocol and forms a trunk with the connected switch.

A threat actor discovers the IOS version and IP addresses of the local switch.

A threat actor sends a message that causes all other devices to believe the MAC address of the threat actor’s device is the default gateway.

Which is an example of an STP attack?

A threat actor sends a BPDU message with priority 0.

A threat actor changes the MAC address of the threat actor’s device to the MAC address of the default gateway.

A threat actor configures a host with the 802.1Q protocol and forms a trunk with the connected switch.

A threat actor discovers the IOS version and IP addresses of the local switch.

A threat actor sends a message that causes all other devices to believe the MAC address of the threat actor’s device is the default gateway.

Which is an example of an address spoofing attack?

A threat actor changes the MAC address of the threat actor’s device to the MAC address of the default gateway.

A threat actor configures a host with the 802.1Q protocol and forms a trunk with the connected switch.

A threat actor discovers the IOS version and IP addresses of the local switch.

A threat actor sends a BPDU message with priority 0.

A threat actor sends a message that causes all other devices to believe the MAC address of the threat actor’s device is the default gateway.

Which is an example of an ARP spoofing attack?

A threat actor sends a message that causes all other devices to believe the MAC address of the threat actor’s device is the default gateway.

A threat actor changes the MAC address of the threat actor’s device to the MAC address of the default gateway.

A threat actor configures a host with the 802.1Q protocol and forms a trunk with the connected switch.
