QUESTION 1
A security team is discussing lessons learned and suggesting process changes after a security breach incident. During the incident, members of the security team failed to report the abnormal system activity due to
a high project workload. Additionally, when the incident was identified, the response took six hours due to management being unavailable to provide the approvals needed. Which two steps will prevent these issues
from occurring in the future? (Choose two.)

A. Introduce a priority rating for incident response workloads.
B. Provide phishing awareness training for the fill security team.
C. Conduct a risk audit of the incident response workflow.
D. Create an executive team delegation plan.
E. Automate security alert timeframes with escalation triggers.

Correct Answer: A,E

QUESTION 2
An engineer is investigating a ticket from the accounting department in which a user discovered an unexpected application on their workstation. Several alerts are seen from the intrusion detection system of unknown outgoing internet traffic from this workstation. The engineer also notices a degraded processing capability, which complicates the analysis process. Which two actions should the engineer take? (Choose two.)

A. Restore to a system recovery point.
B. Replace the faulty CPU.
C. Disconnect from the network.
D. Format the workstation drives.
E. Take an image of the workstation.

Correct Answer: A,E

QUESTION 3
What is a concern for gathering forensics evidence in public cloud environments?

A. High Cost: Cloud service providers typically charge high fees for allowing cloud forensics.
B. Configuration: Implementing security zones and proper network segmentation.
C. Timeliness: Gathering forensics evidence from cloud service providers typically requires substantial time.
D. Multitenancy: Evidence gathering must avoid exposure of data from other tenants.

Correct Answer: D
