| A network engineer is tasked with designing the subnetting for a new corporate network using a 192.168.10.0/24 address space. The engineer needs to create subnets for different departments: IT, HR, Finance, and a Guest network.The requirements are as follows: the IT department needs the most IP addresses, followed by the HR department, then the Finance department,and the Guest network needs the least. Considering the efficient use of address space, which approach should the engineer take to allocate subnet masks appropriately for each department, and what is the expected number of remaining subnets? Option A: The largest subnet is for IT, smaller for HR, even smaller for Finance, smallest for Guest, and 5 subnets remaining. Option B: Equal subnet masks for all departments, no remaining subnets. Option C: Smallest possible subnet masks for all, maximizing the number of subnets. Option D: Allocate based on needs: largest to IT, then HR, Finance, Guest, 5 subnets remaining.right |
| Correct Answer: D |
| Explanation/Reference: Correct Answer – D The engineer should allocate subnet masks based on the specific IP address needs of each department. The IT department, needing the most IP addresses, gets the largest subnet mask. The HR department, with moderate needs, gets a smaller subnet mask. The Finance department, with fewer needs, gets an even smaller subnet mask, and the Guest network, needing the least, gets the smallest subnet mask. This ensures efficient use of address space while meeting each department’s needs and leaves 5 subnets remaining for future use. Option A is incorrect – This option does not clearly indicate the needs-based allocation, which is essential for efficient address space usage. |
