NEW QUESTION # 187
Based on recent alerts, a security analyst thinks a web application server was compromised. The analyst reviews the following server output:
Which of the following best describes what has occurred?
Answer: C
Explanation:
The web-service account www has an interactive tty2 session originating from an external IP address. A service account should not normally have an interactive remote login, indicating unauthorized access.
NEW QUESTION # 188
A security architect works with a client on security operations center (SOC) capabilities. The security architect wants to ensure the log correlation and investigation activities are accurate across the infrastructure.
Which of the following is the best for the client to implement?
Answer: C
Explanation:
Accurate time synchronization is essential for reliable log correlation, making Network Time Protocol the best answer. Security investigations routinely combine events from endpoints, servers, authentication infrastructure, firewalls, cloud services, intrusion-detection systems, and other platforms. If those systems maintain inconsistent clocks, the apparent order of events may be incorrect, making it difficult to reconstruct an attack timeline or correlate activity across multiple sources.
NTP is specifically designed to synchronize computer clocks across distributed systems. RFC 5905 defines NTPv4 as a protocol used to synchronize clocks across internet-connected systems. Synchronized timestamps enable the SOC to determine whether events occurring on separate systems actually belong to the same sequence-for example, authentication followed by process execution, lateral movement, and a subsequent network connection.
ZTNA controls access according to Zero Trust principles but does not synchronize timestamps. Account federation addresses identity interoperability. SASE combines network and security services for distributed environments. APIs can integrate tools and exchange information, but integrated data remains difficult to correlate accurately if each system's timestamps are inconsistent.
For forensic and operational analysis, a consistent time reference is therefore foundational to timeline reconstruction, event sequencing, SIEM correlation, and evidentiary accuracy .

NEW QUESTION # 189
A security operations center manager is concerned that after action reporting is not being completed in a timely manner.
Which of the following will allow the manager to quantify this concern?
Answer: D
Explanation:
Mean time to close is the most relevant measurement because the manager needs to quantify how long cases or incidents remain open before all required closure activities-including after-action documentation-are completed.
An incident may already be technically contained and remediated while administrative closure remains outstanding. Mean time to remediate measures how long it takes to correct or neutralize the security problem, but it does not necessarily include final reporting and formal case closure. Mean time to respond measures how quickly responders begin or perform response activity after detection. Mean time between failures is primarily a reliability metric describing the average operating duration between failures and does not measure SOC reporting performance.
Current Microsoft Sentinel SOC guidance explicitly includes mean time to closure and time-to-closure percentiles among incident-management metrics used to evaluate SOC performance. This directly maps to the manager's concern: if after-action reports delay completion of incidents, the organization's mean closure time will increase and can be trended by analyst, severity, team, or incident category.
Therefore, B provides the quantitative evidence needed to determine whether after-action reporting is preventing incidents from being closed promptly.
Study Guide Reference: Reporting and Communication # Incident Metrics # Mean Time to Close # After- Action Reporting # SOC Performance Measurement # Continuous Improvement.
NEW QUESTION # 190
Which of the following will most likely help decrease false positives?
Answer: B
Explanation:
Alert tuning refines detection rules and thresholds based on environment-specific behavior, reducing noise and eliminating unnecessary or incorrect alerts, which directly decreases false positives.
NEW QUESTION # 191
Multiple users report unexpected mouse movements and terminal windows opening. An analyst reviewing the network traffic logs observes the following:
Which of the following is the most likely reason for the reported symptoms?
Answer: A
Explanation:
TCP port 5900 is the standard port for VNC, which provides interactive remote control of a system's desktop, including mouse movement and opening terminal windows.
