Question 1Which of the following protocols is a TCP/IP-based protocol used to exchange management information between devices connected on a network? 1 pointPOPTelnet HTTP SNMP 2.Question 2Clark, a professional hacker, targeted an organization’s network to steal credentials being shared during active sessions. He collected the physical address of the legitimate users connected to the switch port. Then, Clark started spoofing his physical address with the physical address of a legitimate client and received all the traffic destined for that client.Which of the following attacks has Clark performed in the above scenario? 1 pointDNS poisoning DHCP starvation attack MAC duplicating ARP spoofing 3.Question 3Identify the type of attack in which the attacker sends a large number of connection requests to the target server with fake source IP addresses, creating incomplete TCP connections that use up all network resources. 1 pointDNS poisoning Packet sniffing MAC flooding SYN flood attack 4.Question 4Zara, a network administrator, implements defensive strategies in her organization to increase network security. She follows a list of security best practices to prevent DoS/DDoS attacks.Which of the following practices is not a defensive measure against DoS/DDoS attacks? 1 pointPrevent the return addresses from being overwritten Update the kernel to the latest release and disable unused and insecure services Block all inbound packets originating from the service ports to block the traffic from reflection servers Disable TCP SYN cookie protection 5.Question 5Identify the type of attack in which an attacker seizes control of a valid TCP communication between two computers and gains access to a machine while the communication is in progress. 1 pointPacket sniffing MAC flooding Session hijacking DoS attack

Question 1Smith, a professional hacker, initiated a network sniffing attack on the switched Ethernet environment of a target organization. He employed an automated tool to flood the switch with a fake physical address until the switch translation table became full. When the switch entered fail-open mode, it started acting as a hub by broadcasting packets. Now, Smith could easily accomplish his goal of network sniffing.Identify the type of attack performed by Smith in the above scenario. 1 pointARP spoofing DHCP starvation MAC flooding DNS poisoning 2.Question 2Which of the following tool helps an attacker perform an ARP poisoning attack? 1 pointWireshark High Orbit Ion Cannon BetterCAP Nbtstat

Question 1Williams, a professional hacker, was hired by an organization to damage the reputation of their rival company. Williams spoofed a customer’s rival company’s IP address and initiated sending multiple ICMP ECHO request packets to an IP broadcast network. As a result, all the hosts together started sending responses to the customer’s IP address. These responses were sent to the customer machine, diverting significant traffic toward it and crashing it in the process.Identify the type of attack performed by Williams in the above scenario. 1 pointPing of death attack Smurf attack Fragmentation attack SYN flood attack 2.Question 2Identify the attack technique that purely targets hardware devices by exploiting their security flaws and causes irreversible damage to the system hardware, requiring the victim to replace the hardware. 1 pointPhlashing MAC flooding ARP spoofing DHCP starvation
