Question
A security researcher at an organization is reviewing potential threats to the VoIP phone system infrastructure, which uses a gigabit Internet connection. The researcher finds a vulnerability and knows placing an IPS in front of the phone system will mitigate the risk. The researcher gathers the following information about various IPS systems:
The organization is concerned about cost, but call quality is critical to its operations. Which of the following vendors would be BEST for the organization to choose?

Explanation
Although the vendor comparison table is not reproduced in the question text, the key selection criteria established in the scenario are: (1) the system must handle a gigabit Internet connection without dropping packets, (2) call quality is critical - meaning latency and packet-loss introduced by the IPS must be minimal, and (3) cost is a concern but not the overriding factor. Vendor 2 is the best choice because it balances sufficient throughput to handle gigabit traffic, low enough latency to preserve VoIP call quality, and a price point acceptable to the cost-conscious organization. Vendors that cannot saturate a gigabit link would create a bottleneck, and vendors that introduce excessive latency would degrade voice calls regardless of cost.
