Which of the following is a Network Performance Enhancement offered by Akamai?

Traffic shaping is a Network Performance Enhancement provided by Akamai. This technique refers to the management of data transfer rates to optimize or guarantee performance, lower latency, and ensure a fair share of available bandwidth among users. It allows organizations to prioritize certain types of traffic based on their specific needs, ensuring that critical applications operate efficiently even during peak load times.

By implementing traffic shaping, Akamai can enhance the user experience by reducing congestion and improving the delivery speed of content. This is particularly important for services that require consistent performance, such as video streaming or real-time communications.

In contrast, the other options do not focus specifically on network performance enhancement. VPN services primarily provide security and privacy for users, while email marketing tools and social media integration serve marketing purposes rather than enhancing network performance.
