What are some common IP spoofing attacks? Select all that apply.

• on-path attacks
• replay attacks
• smurf attacks
• KRACK attacks

Question 8)
A malicious actor impersonates a web browser or web server by placing themselves between two devices, then sniffing the packet information to discover the IP and MAC addresses. Which type of attack is this?

• Malware attack
• On-path attack
• Smurf attack
• Packet flooding attack

Question 9)
Fill in the blank: The _____ network attack occurs when an attacker intercepts a data packet in transit, then repeats it at another time.

• replay

Question 10)
Which attack involves an attacker sniffing an authorized user’s IP address and flooding it with packets?

• Ping of Death

Question 11)
A security team investigates a server that has been overwhelmed with SYN packets. What does this scenario describe?

• Ping of Death
• On-path attack
• ICMP flood attack
• SYN flood attack

Question 12)
Which of the following statements correctly describe passive and active packet sniffing? Select three answers.

• Passive packet sniffing may enable attackers to change the information a packet contains.
• The purpose of passive packet sniffing is to read data packets while in transit.
• Using only websites with HTTPS at the beginning of their domain names provides protection from packet sniffing.
• Active packet sniffing may enable attackers to redirect the packets to unintended ports.

Question 13)
As a security professional, you research on-path, replay, and smurf attacks in order to implement procedures that will protect your company from these incidents. What type of attack are you learning about?

• Ping of death
• Packet sniffing
• SYN flooding

Question 14)
In which attack would malicious actors gain access to a network, put themselves between a web browser and a web server, then sniff the packet to learn the devices’ IP and MAC addresses?

• On-path attack
• Malware attack
• Smurf attack
• Packet flooding attack

Question 15)
What type of attack occurs when an attacker intercepts a data packet in transit and delays it or repeats it at another time?

• SYN flood
• smurf
• on-path
• replay

Question 16)
Fill in the blank: A ___ attack happens when a malicious actor sniffs an authorized user’s IP address and floods it with packets.
