Question 23
What is a honeypot used for in network security?
a) To monitor legitimate traffic
b) To act as a decoy system to attract and analyze attacks
c) To filter out malicious traffic
d) To encrypt sensitive data
Correct Answer: b) To act as a decoy system to attract and analyze attacks
Explanation: A honeypot is a deliberately vulnerable system set up to lure attackers, allowing network administrators to analyze attack methods without compromising actual systems.
Question 24
What does an Access Control List (ACL) do in networking?
a) It assigns dynamic IP addresses
b) It filters network traffic based on security rules
c) It creates VLANs on a network
d) It logs user activities on the network
Correct Answer: b) It filters network traffic based on security rules
Explanation: ACLs control access to network resources by filtering traffic according to predefined rules, enhancing network security.
Question 25
What happens during the power-on self-test (POST) process?
a) The operating system is loaded into memory
b) A quick check of hardware components is performed at startup
c) The system connects to the internet
d) The CPU is overclocked for faster performance
Correct Answer: b) A quick check of hardware components is performed at startup
Explanation: POST is a diagnostic testing process that checks hardware components like the CPU, memory, and storage devices before the operating system loads.
Question 26
What is a rogue access point?
a) A wireless access point with advanced encryption
b) A wireless access point installed without authorization
c) A wired device that monitors network traffic
d) A firewall used to block unwanted traffic
Correct Answer: b) A wireless access point installed without authorization
Explanation: A rogue access point is an unauthorized device on a network, potentially compromising network security by creating vulnerabilities.
Question 27
What does attenuation refer to in networking?
a) Signal interference from other devices
b) Loss of signal strength over distance
c) Amplification of weak signals
d) Data encryption for secure transmission
Correct Answer: b) Loss of signal strength over distance
Explanation: Attenuation is the gradual weakening of a signal as it travels over a medium, reducing the quality or speed of data transmission.
Question 28
What is the primary purpose of DHCP (Dynamic Host Configuration Protocol)?
a) To encrypt network traffic
b) To assign IP addresses automatically
c) To resolve domain names to IP addresses
d) To provide remote access to a network
Correct Answer: b) To assign IP addresses automatically
Explanation: DHCP automates the process of assigning IP addresses to devices on a network, ensuring efficient address management.
Question 29
Which protocol is used to securely transfer files between systems over the internet?
a) FTP
b) SFTP
c) SMTP
d) POP
Correct Answer: b) SFTP
Explanation: Secure File Transfer Protocol (SFTP) provides a secure method for transferring files between systems, unlike FTP, which does not encrypt data.
Question 30
What is a key feature of the RADIUS protocol in network security?
a) It assigns dynamic IP addresses
b) It authenticates users connecting to a network remotely
c) It resolves MAC addresses to IP addresses
d) It provides encrypted communication between servers
Correct Answer: b) It authenticates users connecting to a network remotely
Explanation: RADIUS (Remote Authentication Dial-In User Service) is used to authenticate and authorize remote users connecting to a network.
Question 31
Which IPv6 address type is used to send data to the nearest router?
a) Unicast
b) Multicast
c) Broadcast
d) Anycast
Correct Answer: d) Anycast
Explanation: Anycast addresses in IPv6 are designed to route data to the nearest interface in terms of routing distance, commonly used for routers.
Question 32
What is a “collision domain” in networking?
a) A network segment where data collisions occur
b) A wireless network with low signal strength
c) A VLAN segment that restricts communication
d) A section of a network with encrypted traffic
Correct Answer: a) A network segment where data collisions occur
Explanation: A collision domain is a network segment where data collisions can occur if two devices attempt to send data simultaneously.
Question 33
What is the role of Active Directory in a Windows Server environment?
a) It provides firewall protection
b) It manages user accounts, permissions, and network resources
c) It assigns IP addresses automatically
d) It filters network traffic based on predefined rules
Correct Answer: b) It manages user accounts, permissions, and network resources
Explanation: Active Directory is a directory service in Windows Server environments used to manage user accounts, access permissions, and resources across the network.
Question 34
What type of backup method involves copying all data that has changed since the last full backup?
a) Incremental backup
b) Differential backup
c) Full backup
d) Mirror backup
Correct Answer: b) Differential backup
Explanation: A differential backup saves all data that has changed since the last full backup, unlike incremental backups, which only save data changed since the last backup (full or incremental).
Question 35
Which topology uses a central hub to connect all devices in a network?
a) Ring topology
b) Star topology
c) Mesh topology
d) Bus topology
Correct Answer: b) Star topology
Explanation: In a star topology, all devices connect to a central hub or switch, which manages the flow of data between devices on the network.
Question 36
What is a MAC address used for in networking?
a) It assigns IP addresses to network devices
b) It encrypts data being transmitted
c) It provides a unique identifier for a network device
d) It filters unwanted traffic from the network
Correct Answer: c) It provides a unique identifier for a network device
Explanation: A MAC (Media Access Control) address is a unique physical identifier assigned to network interfaces, ensuring devices can be properly identified within a network.
Question 37
What is the main purpose of a packet sniffer in network management?
a) To encrypt data packets for secure transmission
b) To capture and analyze network traffic
c) To block malicious packets from entering the network
d) To assign IP addresses to network devices
Correct Answer: b) To capture and analyze network traffic
Explanation: A packet sniffer is a network monitoring tool that captures data packets as they travel across a network, allowing administrators to analyze traffic for troubleshooting or security purposes.
Question 38
What is the purpose of NAT (Network Address Translation)?
a) To resolve domain names to IP addresses
b) To allow private IP addresses to communicate with public networks
c) To assign IP addresses to devices on a network
d) To provide encrypted communication between devices
Correct Answer: b) To allow private IP addresses to communicate with public networks
Explanation: NAT enables devices with private IP addresses to access external networks (like the internet) by translating private addresses into public ones.
Question 39
What is the maximum transmission rate for a 10BaseT network?
a) 10 Mbps
b) 100 Mbps
c) 1 Gbps
d) 10 Gbps
