1. What type of attack occurs when a threat actor sends packets with false MAC or IP addresses?
- VLAN attacks
- address spoofing
- DHCP attacks
- ARP attacks
Explanation: Address spoofing occurs when a threat actor sends packets that have false MAC or IP addresses.
2. What prevents many types of attacks including MAC table overflow attacks and DHCP starvation attacks?
- IP Source Guard (IPSG)
- DHCP Snooping
- Dynamic ARP inspection (DAI)
- Port Security
Explanation: Port Security prevents many types of attack including CAM table overflow attacks and DHCP starvation attacks.
3. What type of attack sends false address requests to a server until all addresses are used and none are available for legitimate users?
- VLAN attack
- address spoofing
- DHCP attack
- ARP attack
Explanation: DHCP attacks include DHCP starvation which is an attack in which false requests are made to a DHCP server until all available addresses are exhausted.
4. What prevents DHCP starvation and spoofing attacks?
- IP Source Guard (IPSG)
- Dynamic ARP Inspection (DAI)
- Port Security
- DHCP Snooping
Explanation: DHCP Snooping prevents DHCP starvation and DHCP spoofing attacks.
5. What prevents MAC and IP address spoofing attacks?
- IP Source Guard (IPSG)
- Dynamic ARP Inspection (DAI)
