Network+ DoS and ARP Poisoning Attack Quiz

1. What is a ping flood attack?

Sending excessive ICMP echo requests to overwhelm a target

Poisoning ARP tables with fake entries

Exploiting DNS vulnerabilities

Manipulating routing protocols

2. What is the main advantage of using a content delivery network (CDN) against DDoS attacks?

It distributes traffic across multiple servers globally

It eliminates the need for firewalls

It encrypts all network data

It removes the target from the internet

3. Which tool is commonly used to detect and analyze ARP poisoning attacks?

Wireshark packet analyzer

DHCP server logs only

DNS query logs

Firewall ACLs

4. What is ARP inspection used for in network security?

To verify legitimate ARP messages and prevent spoofing

To increase network bandwidth

To encrypt ARP traffic

To monitor DNS queries

5. How does an amplification attack work in DDoS scenarios?

It uses compromised servers to reflect traffic to the target

It increases the attacker's bandwidth

It encrypts network packets

It modifies routing protocols

6. What type of DoS attack targets application-level services?

Volumetric attack

Protocol attack

Application-layer attack

Amplification attack

7. Which of the following is a defense mechanism against SYN flood attacks?

SYN cookies

MAC filtering

DNS filtering

VLAN segmentation

8. In an ARP poisoning attack, what is being spoofed?

The MAC address is associated with a false IP address

The IP address is associated with a false MAC address

The DNS records are modified

The routing table entries are changed

9. What is the purpose of rate limiting in DoS mitigation?

To block all traffic

To restrict the amount of traffic processed per time unit

To encrypt all packets

To disable network interfaces

10. Which network device can help prevent ARP poisoning by validating ARP messages?

Managed switches with DHCP snooping

Hubs

Repeaters

Wireless access points

11. What is the primary goal of a Denial of Service (DoS) attack?

Steal sensitive data from servers

Make network resources unavailable to legitimate users

Gain unauthorized administrative access

Encrypt files for ransom

12. Which protocol is vulnerable to ARP poisoning attacks?

HTTPS

ARP (Address Resolution Protocol)

TLS

SSH

13. What is the difference between a DoS and DDoS attack?

DoS uses one source; DDoS uses multiple sources

DoS targets servers; DDoS targets routers

DoS is illegal; DDoS is legal

DoS uses TCP; DDoS uses UDP

14. Which mitigation technique helps protect against ARP poisoning?

Implementing static ARP entries

Disabling all network devices

Increasing bandwidth capacity

Enabling DHCP snooping alone

15. How can you detect an ARP poisoning attack in progress?

Monitor for duplicate IP addresses on the network

Check for excessive bandwidth usage

Review firewall logs only

Monitor DNS query logs

16. What is a botnet in the context of DDoS attacks?

A network of infected computers controlled by an attacker

A legitimate tool for network monitoring

A firewall configuration

A type of VPN protocol

17. Which of the following is a characteristic of a SYN flood attack?

It manipulates MAC address tables

It exploits the three-way TCP handshake

It targets the application layer

It uses DHCP requests

18. What does ARP poisoning accomplish on a local network?

It encrypts all network communications

It associates an attacker's MAC address with a legitimate IP address

It blocks DNS resolution

It floods the network with ICMP packets

19. Which layer of the OSI model is primarily targeted by ARP poisoning attacks?

Application layer

Transport layer

Network layer

Data Link layer

20. In a Distributed Denial of Service (DDoS) attack, what role do compromised computers play?

They store stolen data

They serve as botnets to flood the target

They encrypt network traffic

They authenticate users
