CompTIA Network+ (N10-009) — Question 471

A global company has acquired a local company. The companies are geographically separate. The fully utilized IP address ranges for the two companies are as follows:

• Global company: 10.0.0.0/16
• Local company: 10.0.0.0/24

Which of the following can the network engineer do to quickly connect the two companies and minimize user disruption?

Answer options

• A. Assign static routing to advertise the local company's network.
• B. Assign an overlapping IP address range to both companies.
• C. Assign a new IP address range to the local company.
• D. Assign a NAT range to the local company.

Correct answer: D

Explanation

The correct answer is D, as assigning a NAT range allows the local company's IP addresses to be translated into a different address space, facilitating communication without conflict. Option A is incorrect because static routing won't resolve the overlap issue. Option B is not feasible as overlapping IP ranges would cause routing conflicts. Option C would work but may require significant reconfiguration and could disrupt users.
