Validation
Correct Answer
A. AuthenticationExplanation
Authentication is the process of verifying the claimed identity of a user. It involves confirming the user's identity through the use of credentials such as passwords, biometrics, or security tokens. This ensures that the user is who they claim to be before granting them access to a system or resource. Identification refers to the act of identifying a user, while verification is the process of confirming the accuracy of the information provided. Validation, on the other hand, typically refers to the process of checking the integrity and validity of data.Rate this question:

QUESTION NO: 344 Which of the following is planted on an infected system and deployed at a predetermined time?
- A.
Logic bomb
- B.
Trojan horse
- C.
Worm
- D.
Rootkit
Correct Answer
A. Logic bombExplanation
A logic bomb is a malicious code that is planted on an infected system and is programmed to execute a specific action at a predetermined time or when certain conditions are met. Unlike a Trojan horse or a worm, which are designed to spread and infect other systems, a logic bomb remains dormant until triggered. Once triggered, it can cause damage to the system, such as deleting files, stealing data, or disrupting operations. Therefore, a logic bomb fits the description of being planted on an infected system and deployed at a predetermined time.Rate this question:

QUESTION NO: 345 Which of the following allows a user to float a domain registration for a maximum of five days?
- A.
DNS poisoning
- B.
Domain hijacking
- C.
Spoofing
- D.
Kiting
Correct Answer
D. KitingExplanation
Kiting allows a user to float a domain registration for a maximum of five days. Kiting refers to the practice of registering a domain name and then canceling the registration within the grace period, which is typically five days. This allows the user to temporarily use the domain without actually paying for it. It is a deceptive practice that takes advantage of the grace period offered by domain registrars.Rate this question:

QUESTION NO: 346 According to company policy an administrator must logically keep the Human Resources department separated from the Accounting department. Which of the following would be the simplest way to accomplish this?
- A.
NIDS
- B.
DMZ
- C.
NAT
- D.
VLAN
Correct Answer
D. VLANExplanation
A VLAN (Virtual Local Area Network) would be the simplest way to logically separate the Human Resources department from the Accounting department. VLANs allow for the creation of separate virtual networks within a physical network infrastructure, allowing for different departments to be isolated from each other while still sharing the same physical resources. This would ensure that the two departments remain separate and their network traffic does not mix, in accordance with the company policy.Rate this question:

QUESTION NO: 347 Which of the following is an attack which is launched from multiple zombie machines in attempt to bring down a service?
- A.
DoS
- B.
Man-in-the-middle
- C.
DDoS
- D.
TCP/IP hijacking
Correct Answer
C. DDoSExplanation
A DDoS (Distributed Denial of Service) attack is launched from multiple zombie machines, which are compromised computers or devices controlled by an attacker. The goal of a DDoS attack is to overwhelm a targeted service or website with a flood of traffic, making it unavailable to legitimate users. This attack is different from a DoS (Denial of Service) attack, which is launched from a single source, as it utilizes multiple sources to amplify the impact and make it harder to defend against. A DDoS attack can cause significant disruption and financial loss for the targeted organization.Rate this question:

QUESTION NO: 348 Which of the following will MOST likely allow an attacker to make a switch function like a hub?
- A.
MAC flooding
- B.
ARP poisoning
- C.
DNS poisoning
- D.
DNS spoofing
Correct Answer
A. MAC floodingExplanation
MAC flooding is a technique in which an attacker floods a switch with fake MAC addresses, causing the switch to enter into a fail-open mode and behave like a hub. This allows the attacker to intercept and view all network traffic passing through the switch, compromising the security of the network. ARP poisoning, DNS poisoning, and DNS spoofing are all different attack techniques that can be used to manipulate network traffic, but they do not specifically cause a switch to function like a hub.Rate this question:

QUESTION NO: 349 Which of the following is commonly programmed into an application for ease of administration?
- A.
Back door
- B.
Worm
- C.
Zombie
- D.
Trojan
Correct Answer
A. Back doorExplanation
A back door is commonly programmed into an application for ease of administration. It allows authorized individuals to bypass normal authentication processes and gain access to the system or application. This can be useful for system administrators or developers who need to troubleshoot or make changes without going through the usual authentication steps. However, back doors can also be exploited by unauthorized individuals, making them a potential security risk if not properly managed and secured.Rate this question:

QUESTION NO: 350 Which of the following is a technique used by hackers to identify unsecured wireless network locations to other hackers?
- A.
Bluesnarfing
- B.
War dialing
- C.
War chalking
- D.
War driving
Correct Answer
C. War chalkingExplanation
War chalking is a technique used by hackers to identify unsecured wireless network locations to other hackers. It involves marking or drawing symbols on public spaces, such as walls or pavements, to indicate the presence of an unsecured Wi-Fi network. These symbols serve as a signal to other hackers that the network is vulnerable and can be easily exploited. By using war chalking, hackers can quickly identify and target unsecured networks for unauthorized access or malicious activities.Rate this question:
