CompTIA DataX (CNX-001) — Question 40

A company's IT department is expected to grow from 100 to 200 employees, and the sales department is expected to grow from 1,000 to a maximum of 2,000 employees. Each employee owns a single laptop with a single IP allocated. The network architect wants to deploy network segmentation using the IP range 10.0.0.0/8. Which of the following is the best solution?

Answer options

• A. Allocate 10.1.0.0/30 to the IT department. Allocate 10.2.0.0/16 to the sales department.
• B. Allocate 10.1.0.0/16 to the IT department. Allocate 10.2.1.0/24 to the sales department.
• C. Allocate 10.1.0.0/22 to the IT department. Allocate 10.2.0.0/15 to the sales department.
• D. Allocate 10.1.0.0/16 to the IT department. Allocate 10.2.1.0/25 to the sales department.

Correct answer: C

Explanation

The correct answer is C because allocating 10.1.0.0/22 provides enough IP addresses for the IT department's growth, allowing for 1024 addresses, which accommodates the increase from 100 to 200 employees. For the sales department, 10.2.0.0/15 offers enough addresses for growth from 1,000 to 2,000 employees, providing over 30,000 addresses. The other options do not provide sufficient addresses for either department's future needs.
