Which of the following is a common risk when using public Wi-Fi networks?

The identified risk of eavesdropping on unencrypted communication when using public Wi-Fi networks highlights a significant security concern associated with such connections. Public Wi-Fi networks are often unsecured, meaning that data transmitted over these networks can be intercepted by malicious actors. When users connect to a public Wi-Fi network without using encryption protocols, their activities—such as emails, online transactions, and personal information—can be accessed and monitored by anyone else on the same network.

This poses a serious threat to privacy and data security, making it essential for individuals to exercise caution when using public Wi-Fi. Utilizing virtual private networks (VPNs) or ensuring that websites use HTTPS can help mitigate this risk. Awareness of this issue is crucial for maintaining data security in a world where public Wi-Fi is prevalent in locations such as cafes, airports, and hotels.

The other options, while they might present certain inconveniences, do not represent the same level of security risk as eavesdropping. Connection speed fluctuations and the inability to stream media are typical concerns that can arise from network conditions but do not compromise the security of user data. Access to faster internet speeds is desirable but unrelated to the risks associated with public Wi-Fi usage. Thus, focusing on eavesdropping emphasizes
