What is the correct command to configure a switch to use DNS to resolve a name to a matching IP address?
Final answer: The correct command to configure a switch to use DNS to resolve a name to a matching IP address is (option D) ip name-server ip-address1 ip-address2. The 'ip name-server ip-address1 ip-address2' command is used to configure a switch to use DNS to resolve a name to a matching IP address.
Explanation:
In the context of configuring a switch to use DNS (Domain Name System) to resolve a name to a matching IP address, the correct command would be 'ip name-server ip-address1 ip-address2'. This command sets up the DNS server for the network device, and link the DNS name of the device to its IP address. Here, ip-address1 and ip-address2 are the IP addresses of the DNS servers to be used. The switch then can resolve names into IP addresses using these configured DNS servers.
To configure a switch to use DNS for name resolution, you need to specify the IP addresses of the DNS servers that the switch will use to resolve names to IP addresses. The 'ip name-server' command allows you to configure one or more DNS servers on the switch. By providing the IP addresses of the DNS servers in the command, the switch will be able to query these servers for name resolution.
Using DNS for name resolution is important in network settings as it eliminates the need to remember and manually input IP addresses for devices. Instead, you can refer to devices by their domain names, which are easier to remember and manage.
In summary, by using the 'ip name-server' command with the appropriate IP addresses of DNS servers, you can configure a switch to use DNS for name resolution, allowing the switch to resolve names to matching IP addresses efficiently.
