What happens in a DDoS attack?

A large e-commerce company is preparing its infrastructure to withstand potential Distributed Denial of Service (DDoS) attacks, especially during peak shopping seasons. Which of the following strategies would be most effective in mitigating the impact of a DDoS attack?Group of answer choicesImplementing strict password policies and two-factor authentication for all user accounts.Regularly updating website content and server software to prevent malware infections.Distributing network traffic across multiple servers using a load balancer.Encrypting all data transmissions with high-level encryption protocols.

Question 1What do network-level Denial of Service (DoS) attacks target?1 pointThe personal information of employeesCommonly used software applicationsAll hardware within an organizationNetwork bandwidth2.Question 2Which of the following statements accurately describe Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks? Select three answers.1 pointA DoS attack targets a network or server.In both DoS and DDoS attacks, if any part of the network is overloaded, the attacks are successful.A DDoS attack may use multiple devices in different locations to flood the target network with unwanted traffic.A DoS attack involves multiple hosts carrying out the attack.3.Question 3A security manager is training their team to identify when a server has experienced a SYN-flood attack. What might indicate to the team members that their organization is at risk?1 pointThe port numbers in the data packets are incorrect.An oversized ICMP packet is sent to the network server.The server has stopped responding after receiving an unusually high number of incoming SYN packets.A large number of ICMP packets are delivered to the organization’s servers.4.Question 4Fill in the blank: The DoS attack _____ occurs when a malicious actor sends an oversized ICMP packet to a server.1 pointon-pathSYN flood Ping of Deathsmurf5.Question 5Which of the following statements correctly describe passive and active packet sniffing? Select three answers.1 pointActive packet sniffing may enable attackers to redirect the packets to unintended ports.A company can avoid using unprotected Wi-Fi to help protect itself from packet sniffing.Passive packet sniffing enables attackers to change the information a packet contains.Passive packet sniffing allows malicious actors to view the information going in and out of the targeted device.6.Question 6As a security professional, you implement safeguards against attackers changing the source IP of a data packet in order to communicate over your company’s network. What type of network attack are you trying to avoid?1 pointPing of DeathPassive packet sniffingActive packet sniffingIP spoofing7.Question 7Fill in the blank: _____ is a network attack performed when an attacker changes the source IP of a data packet to impersonate an authorized system and gain access to a network.1 pointA KRACK attackIP spoofingSYN floodingA DoS attack8.Question 8In 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?1 pointSmurf attackPacket flooding attackMalware attackOn-path attack9.Question 9Fill in the blank: The _____ network attack occurs when an attacker intercepts a data packet in transit, then repeats it at another time.1 pointSYN floodsmurfreplayon-path10.Question 10Which combination of DoS and IP spoofing attack can bring down an entire network by flooding an authorized user’s IP address with packets?1 pointSmurf attackOn-path attackReplay attackPing of Death

Which type of DDoS attack involves overwhelming a target system's network bandwidth?Select one:a. Resource exhaustion DDoSb. Protocol-based DDoSc. Volumetric DDoSd. Application-layer DDoS
