Cuestionario Capa de Red - Redes de datos

What is the main purpose of the network layer in the OSI model?

• Route data across the network.

• Establish and terminate connections between devices.

• Provide end-to-end communication services.

• Control the flow of data in the network.

What function does the Internet Protocol (IP) perform in the network layer?

• Assign MAC addresses to network devices.

• Determine the optimal route to send data across the network.

• Provide point-to-point communication services.

• Manage access to the physical transmission medium.

What is the difference between IPv4 and IPv6 in the network layer?

• IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses.

• IPv4 is more secure than IPv6 due to its addressing structure.

• IPv4 offers a greater number of available IP addresses compared to IPv6.

• IPv6 is faster than IPv4 due to its improved design.

What network device operates at the network layer and is used to interconnect separate networks?

• Hub.

• Router.

• Switch.

• Bridge.

What is the main function of a router in the network layer?

• Filter and forward traffic based on MAC addresses.

• Segment a network into broadcast domains.

• Determine the best route to send data across the network.

• Learn MAC addresses and forward traffic based on them.

What is packet fragmentation in the network layer?

• The process of dividing large data packets into smaller fragments for transmission.

• The process of reassembling lost data packets during transmission.

• Converting IP addresses to MAC addresses.

• Assigning IP addresses to network devices.

What is the difference between a public IP address and a private IP address?

• A public IP address is unique on the Internet, while a private IP address is unique within a private network.

• A public IP address is used to access local network resources, while a private IP address is used to access public network resources.

• A public IP address is static, while a private IP address can be dynamic.

• A public IP address is secure and private, while a private IP address is public and accessible from the Internet.

What is a routing protocol in the network layer?

• A set of rules determining how data is transmitted in the network.

• A mechanism used to manage concurrent access to the network.

• A protocol used to establish secure connections on the network.

• A protocol used to determine optimal routes for sending data across the network.

What is the function of the Internet Control Message Protocol (ICMP) in the network layer?

• Provide dynamic routing services.

• Facilitate communication between network devices.

• Diagnose network issues and send error messages.

• Assign IP addresses to network devices.

What is the broadcast address in the network layer?

• An IP address reserved for communications between network devices.

• A unique MAC address assigned to a network device.

• An address used to identify the origin of a data packet.

• An address indicating all devices on a specific network.
