Exam CFR-310 topic 1 question 94 discussion

A. Wireless router Explanation: KRACK (Key Reinstallation Attack) is a vulnerability in the WPA2 protocol used in many wireless routers, making them susceptible to attacks that can decrypt network traffic. D. Access point Explanation: Access points, which also use the WPA2 protocol for wireless communication, are vulnerable to KRACK attacks since the flaw exists in the Wi-Fi security protocol. Incorrect Responses: B. Switch: Switches are used in wired networks, so they are not affected by KRACK, which targets wireless communication. C. Firewall: Firewalls operate at the network level, but KRACK is specific to wireless encryption and does not directly affect firewalls. E. Hub: Hubs are older networking devices used in wired networks, and KRACK is a wireless-related vulnerability.
