Question 880
An analyst receives only critical events although a failed AAA attempt was logged at a lower severity. Which observed result BEST confirms that the security requirement is met?
Explanation
Correct Answer
Firewall and switch events share consistent time ordering and protected transport to the authorized log collector. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. Central logging loses forensic value when clocks disagree or records are dropped; authenticated time and secure logging improve evidence quality. Situation: An analyst receives only critical events although a failed AAA attempt was logged at a lower severity.
Incorrect Answers
An unusual high-volume conversation is identified with attributable endpoints without claiming NetFlow reveals complete application content. This outcome tests NetFlow and telemetry flow analysis and is not sufficient proof of the stated requirement. Here the relevant validation is: Firewall and switch events share consistent time ordering and protected transport to the authorized log collector. Situation: An analyst receives only critical events although a failed AAA attempt was logged at a lower severity.
Unapproved categories or applications are denied while required business services match the intended allow criteria. This outcome tests Application visibility control and URL filtering and is not sufficient proof of the stated requirement. Here the relevant validation is: Firewall and switch events share consistent time ordering and protected transport to the authorized log collector. Situation: An analyst receives only critical events although a failed AAA attempt was logged at a lower severity.
Spoofed gateway ARP frames are rejected while authorized static-IP hosts continue normal access with explicit bindings. This outcome tests Dynamic ARP inspection and spoofed gateway and is not sufficient proof of the stated requirement. Here the relevant validation is: Firewall and switch events share consistent time ordering and protected transport to the authorized log collector. Situation: An analyst receives only critical events although a failed AAA attempt was logged at a lower severity.
