Question
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?
Options
- ALimit the number of users who can access the application.
- BLease a Direct Connect connection to the cloud service provider.
- CImplement QoS to prioritize application traffic.
- DUse a CDN to service the application.

Explanation
QoS (Quality of Service) allows the network administrator to prioritize critical traffic - such as the cloud-based application - over less important traffic. This ensures that even during high bandwidth usage, essential application traffic maintains acceptable performance. Limiting users is restrictive and does not address the root cause. Leasing a Direct Connect (or dedicated line) is effective but expensive, not cost-effective for most use cases. A CDN (Content Delivery Network) improves performance for static content delivery, not for cloud applications requiring real-time interaction. Implementing QoS is the most cost-effective way to reduce lag for prioritized application traffic during congestion.
