CompTIA Network+ (N10-009) — Question 410

Users are experiencing significant lag while connecting to a cloud-based application during peak hours. An examination of the network reveals that the bandwidth is being heavily utilized. Further analysis shows that only a few users are using the application at any given time. Which of the following is the most cost-effective solution for this issue?

Answer options

• A. Limit the number of users who can access the application.
• B. Lease a Direct Connect connection to the cloud service provider.
• C. Implement QoS to prioritize application traffic.
• D. Use a CDN to service the application.

Correct answer: C

Explanation

The correct answer is C, as implementing QoS allows for prioritization of application traffic, which can alleviate lag during peak usage without incurring high costs. Options A and B are not cost-effective solutions; limiting users may hinder access and leasing a Direct Connect is expensive. Option D, while useful, does not specifically address bandwidth issues related to internal traffic.
