Ensure Subnet Connectivity: Route Table Configuration

Answer - C.

This is the default route.

For more information on the default route , please refer to the below link:

To ensure that a subnet can receive requests from all destinations, you need to add a route in the route table that specifies the destination as 0.0.0.0/0. This is known as the default route, and it directs all traffic that does not match any other route in the route table to a particular gateway or internet gateway.

Option A: 255.255.255.255/32 is a broadcast address and is used to send packets to all devices on the same network segment. It is not used to specify a route in a route table.

Option B: 255.255.255.255/0 is not a valid CIDR notation, as the prefix length of the subnet mask cannot be 0.

Option C: 0.0.0.0/0 is the correct option, as it specifies the default route and directs all traffic to a specific gateway or internet gateway.

Option D: 0.0.0.0/32 is also not a valid CIDR notation, as the prefix length of the subnet mask cannot be 32 for a default route.

Therefore, the correct answer is C. 0.0.0.0/0.
