Q11.
How does DNS cache poisoning work?

a.

By exploiting vulnerabilities in DNS servers

b.

By modifying the local hosts file

c.

By redirecting traffic to a different host

d.

Both a and c

Discuss
Answer: (d).Both a and c Explanation:DNS cache poisoning works by exploiting vulnerabilities in DNS servers and redirecting traffic to a different host.
Q12.
What is a potential method for penetration testers to achieve effects similar to DNS cache poisoning?

a.

Conducting timing attacks

b.

Modifying the local hosts file

c.

Securing DNS servers

d.

Exploiting vulnerabilities in DNS software

Discuss
Answer: (b).Modifying the local hosts file Explanation:Penetration testers can modify the local hosts file on compromised systems to achieve effects similar to DNS cache poisoning.
Q13.
Why are DNS cache poisoning attacks less likely to be usefully exploitable for most penetration testers?

a.

Lack of awareness about DNS vulnerabilities

b.

Widespread DNS server security improvements

c.

Difficulty in conducting timing attack windows

d.

Both b and c

Discuss
Answer: (d).Both b and c Explanation:DNS cache poisoning attacks are less likely to be usefully exploitable due to widespread DNS server security improvements and the difficulty in conducting timing attack windows.
Q14.
What is the primary objective of penetration testers in on-path attacks?

a.

Compromising network equipment

b.

Capturing traffic sent to or from a target system

c.

Conducting timing attacks

d.

Inserting themselves into the target system

Discuss
Answer: (b).Capturing traffic sent to or from a target system Explanation:The primary objective of penetration testers in on-path attacks is to capture traffic sent to or from a target system.
Q15.
What is another term used for on-path attacks?

a.

In-Path Attacks

b.

Middle-of-the-Path Attacks

c.

Man-in-the-Middle Attacks

d.

Traffic Manipulation Attacks

Discuss
Answer: (c).Man-in-the-Middle Attacks Explanation:On-path attacks are also referred to as man-in-the-middle attacks.
Q16.
How does ARP spoofing work in conducting on-path attacks?

a.

By compromising network equipment

b.

By manipulating the ARP cache of target machines

c.

By inserting attackers into the target system

d.

By conducting timing attacks

Discuss
Answer: (b).By manipulating the ARP cache of target machines Explanation:ARP spoofing in on-path attacks involves manipulating the ARP cache of target machines, allowing attackers to capture and forward traffic.
Q17.
In the context of ARP spoofing, what can an attacker achieve by falsifying ARP messages on a local network?

a.

Compromising network equipment

b.

Intercepting or capturing and forwarding traffic

c.

Conducting timing attacks

d.

Hijacking sessions on remote systems

Discuss
Answer: (b).Intercepting or capturing and forwarding traffic Explanation:Falsifying ARP messages in ARP spoofing allows attackers to intercept or capture and forward traffic.
Q18.
Where is ARP spoofing effective, and what tool in Kali Linux can be used to conduct this attack?

a.

Only on remote networks; arpsniff

b.

Only on local networks; arpspoof

c.

Both on local and remote networks; wireshark

d.

Only on broadcast domains; metasploit

Discuss
Answer: (b).Only on local networks; arpspoof Explanation:ARP spoofing is effective on local networks, and in Kali Linux, the arpspoof command can be used to conduct this attack.
Q19.
What is the primary purpose of MAC address spoofing for a penetration tester?

a.

Changing the MAC address for security reasons

b.

Identifying devices on a network

c.

Bypassing network access controls and security filters

d.

Manually setting MAC addresses for all network adapters

Discuss
Answer: (c).Bypassing network access controls and security filters Explanation:The primary purpose of MAC address spoofing for a penetration tester is to bypass network access controls, captive portals, and security filters that rely on a system's MAC address for identification.
Q20.
What is a common use for replay attacks?

a.

Modifying network traffic

b.

Intercepting authentication attempts

c.

Conducting timing attacks

d.

Spoofing MAC addresses

Discuss
Answer: (b).Intercepting authentication attempts Explanation:A common use for replay attacks is intercepting authentication attempts.
