1. Which of the following protocols can be used to provide
encrypted communication over an untrusted network?
A. SSH
B. ICMP
C. POP3
D. Telnet
Answer: A) SSH
Rationale: SSH (Secure Shell) is used for securely accessing
network devices and systems over untrusted networks, providing
encrypted communication.
2. Which network protocol provides secure communication for
web traffic by encrypting data between the client and server?
A. FTP
B. HTTP
C. SMTP
D. HTTPS
Answer: D) HTTPS
Rationale: HTTPS (HyperText Transfer Protocol Secure)
encrypts data exchanged between a web browser and a web server,
,ensuring that sensitive data, such as login credentials, remains
secure.
3. What is the purpose of an Intrusion Prevention System (IPS)?
A. To detect malicious activity and block it in real-time
B. To log network activity for later analysis
C. To monitor network bandwidth usage
D. To provide secure remote access to the network
Answer: A) To detect malicious activity and block it in real-time
Rationale: An IPS monitors network traffic for potential threats
and actively takes steps to block malicious activities in real-time.
4. What is the function of a honeypot in network security?
A. To deceive attackers into engaging with a decoy system
B. To prevent unauthorized access to a network
C. To monitor traffic between two devices
D. To create secure remote connections for users
Answer: A) To deceive attackers into engaging with a decoy
system
Rationale: A honeypot is a decoy system set up to attract and
deceive attackers, providing valuable information about attack
methods without risking the main network.
, 5. What is the function of a network firewall?
A. To increase network bandwidth
B. To block unauthorized network traffic
C. To monitor network devices
D. To route packets between subnets
Answer: B) To block unauthorized network traffic
Rationale: A firewall's main function is to monitor and filter
traffic between networks based on predefined security rules,
blocking unauthorized access.
6. Which of the following is an example of a brute-force attack?
A. An attacker intercepting traffic between two systems
B. An attacker attempting to guess a password by trying all
possible combinations
C. An attacker exploiting a vulnerability to crash a server
D. An attacker sending a large volume of traffic to overwhelm a
network
Answer: B) An attacker attempting to guess a password by trying
all possible combinations
Rationale: A brute-force attack involves systematically trying all
possible combinations of passwords until the correct one is found.
