7 / 30

7. How does ARP poisoning work in a Man-in-the-Middle (MitM) attack?

a) ARP poisoning involves flooding a target system with ARP requests to exhaust its ARP cache and disrupt network communication.

b) ARP poisoning involves sending falsified ARP messages to associate the attacker's MAC address with the IP address of a legitimate network device, allowing the attacker to intercept and potentially alter communication between the legitimate parties.

c) ARP poisoning involves intercepting and modifying network traffic to exploit vulnerabilities in the TCP/IP stack of a target system.

d) ARP poisoning involves flooding a target system with ICMP echo request packets (pings) to consume its network bandwidth and resources, rendering it unreachable.

8 / 30

8. How can hybrid topologies enhance network reliability?

10 / 30

10. In a client-server architecture, what is typically stored on the server?

a) Minimal processing power and storage

b) Client-specific data only

c) Shared resources, applications, and databases

d) Temporary cache files

11 / 30

11. How does the `traceroute` command work?

a) By sending ICMP echo requests to the destination host

b) By using the ARP (Address Resolution Protocol) to resolve MAC addresses

c) By sending packets with increasing TTL (Time to Live) values and recording the intermediate router responses

d) By querying the DNS (Domain Name System) server for the IP address of the destination host

12 / 30

12. What is ping flooding in a DoS attack?

a) Ping flooding involves sending a flood of ICMP echo request packets (pings) to a target system to consume its network bandwidth and resources.

b) Ping flooding involves flooding a target system with HTTP requests to overload its web server and render it unavailable.

c) Ping flooding involves flooding a target system with DNS queries to exhaust its DNS server resources and disrupt its domain resolution services.

d) Ping flooding involves intercepting and redirecting network traffic to a malicious server to eavesdrop on communications.
