• Placeholder for the subnet identifier

• Abbreviation for a consecutive group of zero blocks

• Loopback address

• Gateway address

What is the purpose of the ICMP protocol?

• Routing data between different networks

• Sending error messages and operational information about network interactions

• Managing IP address assignments

• Establishing secure communication channels

What protocol is used for dynamically assigning IP addresses to devices on a network?

• DNS

• DHCP

• ICMP

At which level of the OSI model is end-to-end communication and error recovery provided?

• Data Link

• Network

• Transport

• Application

What protocol is used by devices for dynamic discovery of a device's MAC address in a network?

• ARP (Address Resolution Protocol)

• DNS

• ICMP

• HTTP

The router receives a packet intended for the IP address 192.168.1.100, but does not have the corresponding MAC address in its ARP cache. What does the router do next?

• The router sends an ARP request to find the MAC address of 192.168.1.100.

• The router drops the packet.

• The router forwards the packet to all other devices on the network.

• The router assigns a default MAC address to the packet.

How to enable the router interface?

• start interface

• no shutdown

• enable interface

• activate interface

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

• A private IP address can be used on the Internet, while a public IP address cannot.

• A private IP address is used for communication within a local network, while a public IP address is used for communication over the Internet.

• A private IP address is faster than a public IP address.

• A private IP address is automatically assigned by a router.
