Amplifying network signals Filtering network traffic Routing network traffic between different networks Providing network security A router is a Layer 3 device that routes packets between different networks based on IP addresses. 2 / 17 2. 12. What is the purpose of the Address Resolution Protocol (ARP)? a) To map IP addresses to MAC addresses b) To map MAC addresses to IP addresses ) To route packets between networks d) To provide network security Explanation: ARP is used to map IP addresses to MAC addresses. 3 / 17 3. 9. Which class of IP addresses is used for private networks? a) Class A b) Class B c) Class C d) Above All Explanation: Class A, B, and C addresses are public IP addresses. Class D and E are reserved for special purposes. Private IP addresses belong to classes A, B, and C. 4 / 17 4. 3. What type of switch port is used to connect multiple switches together to form a larger network? a) Trunk port b) Access port c) Hybrid port d) Router port Explanation: Trunk ports are used to connect multiple switches together. 5 / 17 5. 14. Which layer of the OSI model is responsible for error detection and correction? a) Physical layer b) Data Link layer c) Network layer d) Transport layer Explanation: The Data Link layer handles error detection and correction. 6 / 17 6. 16. Which type of UTP cable is commonly used for short-distance connections, such as between a computer and a switch? a) Cat5e b) Cat6 c) Cat7 d) Fiber Optic Explanation: Cat5e is a common type of UTP cable used for short-distance connections. 7 / 17 7. 7. How many subnets can be created from a Class C network with a subnet mask of 255.255.255.224? a) 2 b) 4 c) 8 d) 16 Explanation: With a subnet mask of 255.255.255.224, you can create 8 subnets from a Class C network. 8 / 17 8. 10. What is the purpose of a subnet mask? a) To identify the network portion of an IP address b) To identify the host portion of an IP address c) To provide network security d) To route packets between networks Explanation: A subnet mask identifies the network portion of an IP address. 9 / 17 9. 8. Which protocol is connectionless and unreliable? a) TCP b) UDP c) ARP d) ICMP Explanation: UDP is a connectionless and unreliable protocol. Where TCP is a Connection oriented and Reliable protocol. 10 / 17 10. 15. What is the purpose of a MAC address? a) To uniquely identify a network device on a network b) To route packets between different networks c) To provide network security d) To assign IP addresses to devices Explanation: A MAC address is a unique identifier assigned to network interfaces. 11 / 17 11. Which network device operates at the physical and data link layers of the OSI model and forwards frames based on MAC addresses? Router Switch Hub Modem A switch is a Layer 2 device that forwards frames based on MAC addresses. 12 / 17 12. 11. What is the maximum data transfer rate of a 10 Gigabit Ethernet network? a) 10 Mbps b) 100 Mbps c) 1 Gbps d) 10 Gbps Explanation: 10 Gigabit Ethernet has a maximum data transfer rate of 10 Gbps. 13 / 17 13. 4. What is the purpose of DTP? a) To negotiate trunk links between switches b) To assign IP addresses to devices c) To provide network security d) To route packets between networks Explanation: DTP is used to negotiate trunk links between switches. 14 / 17 14. 13. At which layer of the OSI model does encryption and decryption occur? a) Physical layer b) b) Data Link layer c) Network layer d) Presentation layer Explanation: Encryption and decryption typically occur at the Presentation layer. 15 / 17 15. 5. What is the purpose of VLANs? a) To segment a network into multiple logical networks b) To provide network security c) To route packets between networks d) To amplify network signals Explanation: VLANs are used to segment a network into multiple logical networks. 16 / 17 16. 6. What type of switch port is used to connect devices to a network, such as computers and printers? a) Trunk port b) Access port c) Hybrid port d) Router port Explanation: Access ports are used to connect devices to a network. 17 / 17 17. 2. Which DTP mode allows a port to automatically negotiate a trunk link if the connected port is in desirable or auto mode? a) Dynamic auto b) Dynamic desirable c) Passive d) None of the above Explanation: Dynamic desirable mode allows a port to automatically negotiate a trunk link.
