CompTIA Security+ (SY0-701) — Question 197

A network engineer deployed a redundant switch stack to increase system availability. However, the budget can only cover the cost of one ISP connection. Which of the following best describes the potential risk factor?

Answer options

• A. The equipment MTBF is unknown.
• B. The ISP has no SLA.
• C. An RPO has not been determined.
• D. There is a single point of failure.

Correct answer: D

Explanation

The correct answer is D, as having only one ISP connection creates a single point of failure; if that connection goes down, the entire network loses internet access. Options A, B, and C do not directly address the risk associated with relying on a single ISP connection, which is the core issue of redundancy and availability.
