Question 300
A branch design for Copperline Studios has two requirements: (1) create equal /27 subnets from a /24, and (2) distinguish a directed broadcast from an ordinary host IP. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) Borrowing three host bits creates eight /27 subnets, each normally offering 30 usable hosts. (2) The all-ones host portion represents the subnet-directed broadcast in ordinary IPv4 subnets. Neither action is a substitute for the other.
Incorrect Answers
The second step covers (2), but the first addresses serve a home office with one combined firewall, switch, and wireless radio. An all-in-one small-office appliance consolidates routing, NAT, Ethernet access and Wi-Fi. It leaves outcome (1) unfulfilled.
The first step covers (1), but the second addresses enable inter-VLAN routing on a campus distribution device. SVIs terminate VLAN IP subnets while hardware routing forwards packets between VLANs. It leaves outcome (2) unfulfilled.
Neither step is the requested pair: Use a Layer 2 Ethernet switch is for provide wire-speed forwarding within the same access VLAN, and Deploy an application server on a reachable network is for host a central application consumed by employee laptops. A Layer 2 switch learns source MAC addresses and forwards frames by destination MAC within a broadcast domain. The proposed plan misses the two stated outcomes.
