101 · Question #578

A server is operating on the network 10.1.0.0/24. The BIG-IP device is operating on the 192.168.0.0/24 net. What is required to enable the several and BIG-IP device to communicate properly?

The correct answer is C. Router. Two hosts on different IP subnets require a router to forward packets between them, as switches and hubs only operate within a single broadcast domain.

Why each option

Two hosts on different IP subnets require a router to forward packets between them, as switches and hubs only operate within a single broadcast domain.

AFirewall

A firewall filters and controls traffic based on rules but does not inherently route packets between separate IP networks without also functioning as a router.

BSwitch

A switch operates at Layer 2 (Data Link) and connects devices within the same subnet using MAC addresses, so it cannot forward traffic between two different IP networks.

CRouterCorrect

A router operates at Layer 3 and is specifically designed to forward packets between different IP networks. Because 10.1.0.0/24 and 192.168.0.0/24 are distinct subnets, a router is required to look up the destination network in its routing table and forward traffic accordingly. Without a router, hosts on these two subnets have no path to reach each other.

DHub

A hub is a Layer 1 (Physical) device that simply repeats electrical signals to all ports within a single network segment and has no awareness of IP addressing.
