Exam CFR-310 topic 1 question 51 discussion

B. A malicious user is exporting sensitive data. Explanation: The scenario describes excessive traffic from an external-facing host to an unknown location on the Internet, which suggests the possibility of data exfiltration. Why the other answers are less suitable: A. The network is experiencing a denial of service (DoS) attack: A DoS attack typically involves overwhelming a target with inbound traffic to disrupt services, not outbound traffic to an unknown destination. C. Rogue hardware has been installed: Rogue hardware refers to unauthorized devices installed on the network, but the scenario focuses on abnormal traffic patterns rather than unauthorized devices. D. An administrator has misconfigured a web proxy: While a misconfigured proxy could cause connectivity issues, it would not typically result in excessive traffic to an unknown external destination.
