27. Using the output below: IP Address: 172.25.1.39 Subnet Mask: 255.255.255.0 Router: 172.25.1.252 Name Server: 172.25.1.4 Which of the following is the default gateway?
Answer: A
The default gateway is 172.25.1.252.
The default gateway is the IP address of the router that connects the local network to other networks. In this case, the router's IP address is identified as 172.25.1.252.
A) 172.25.1.252
This option is correct because it represents the IP address of the router, which functions as the default gateway for devices on the local network. The default gateway is essential for routing traffic from the local network to external networks.
B) 172.25.1.39
This option is incorrect because it is the IP address assigned to a specific device on the network, not the gateway. A device's IP address does not serve the function of routing traffic outside the local subnet.
C) 172.25.1.4
This option is incorrect as it represents the name server's IP address, which is used for domain name resolution. While it is a necessary component of network configuration, it does not serve as the default gateway.
D) 255.255.255.0
This option is incorrect because it indicates the subnet mask, which is used to define the network and host portions of an IP address. It does not refer to a gateway and cannot route traffic.
Conclusion
The option 172.25.1.252 is definitively the correct answer as it is the address of the router, serving as the default gateway for the local network. Other options either represent individual device addresses or configurations that do not fulfill the function of routing traffic to external networks.
