NEW QUESTION # 153
Which of the following is a reason why a SOC team member might spend extra time on a routine incident prior to closing it?
Answer: D
Explanation:
Spending additional time on a routine incident can allow the analyst to develop automation or documented procedures that will handle similar incidents more efficiently in the future. Creating an automated process reduces manual effort, improves response consistency, and enables faster handling of repeated incidents.
NEW QUESTION # 154
Which of the following is the most important reason why tactics, techniques, and procedures (TTP) are beneficial to a defensive strategy?
Answer: C
Explanation:
Tactics, techniques, and procedures represent the behavioral characteristics of an adversary rather than merely individual technical artifacts. A tactic describes the adversary's objective, a technique identifies how that objective is achieved, and procedures represent the specific implementation observed during an intrusion.
Consequently, TTP intelligence allows defenders to understand how an attacker operates , including patterns of reconnaissance, persistence, privilege escalation, lateral movement, command-and-control activity, and other operational behaviors.
Options A and B focus primarily on indicators of compromise such as IP addresses and hashes. These are useful for detection, but they are comparatively fragile because attackers can replace infrastructure, change domains, regenerate malware, or modify files to produce different hashes. Option C is broader than an individual IoC, but tools can likewise be replaced or modified. Behavioral knowledge is generally more durable because changing established operational methods imposes greater cost on an adversary.
The CS0-004 objectives explicitly place TTPs, Pyramid of Pain, MITRE ATT & CK, attribution, IoC analysis, and behavioral indicators within threat intelligence and threat-hunting concepts.

NEW QUESTION # 155
A security analyst needs to identify the devices in a critical infrastructure network that handles an oil and gas pipeline. The network has devices connected over IPv4 using either HTTP or Modbus protocols running on the standard ports. Which of the following approaches should the analyst use to achieve the objective?
Answer: B
Explanation:
Critical infrastructure and ICS environments require non-intrusive identification methods to avoid disrupting operational technology devices. Banner grabbing with netcat against the standard HTTP (80) and Modbus (502) ports allows the analyst to identify devices and services with minimal impact. More aggressive scanning techniques, service enumeration, and vulnerability scanning can adversely affect sensitive ICS systems and are generally avoided unless specifically approved and tested.
NEW QUESTION # 156
Which of the following should a cybersecurity analyst utilize when a notification is inaccurate?
Answer: B
Explanation:
Alert tuning is the appropriate response when a security notification is inaccurate. Detection technologies depend on rules, thresholds, signatures, behavioral models, correlation conditions, exclusions, and environmental context. When these settings are too broad or poorly calibrated, the result may be false positives, unnecessary notifications, or detections that do not accurately represent the underlying activity.
Tuning involves examining the detection that generated the notification and modifying its logic so it more accurately distinguishes malicious activity from legitimate behavior. This can include adjusting thresholds, excluding known-benign entities, refining queries, changing correlation windows, or adding contextual conditions. Microsoft Sentinel specifically recommends modifying analytics rules or creating appropriate exceptions to manage false positives, and its current guidance identifies tuning as a method of reducing noise and improving detection quality.
Data enrichment adds additional context but does not inherently correct an inaccurate detection. Dashboard creation changes visualization rather than detection logic. Threat hunting is a proactive investigative activity used to search for threats that may not have generated alerts; it is not the primary technique for correcting inaccurate notifications.

NEW QUESTION # 157
During a recent security event, log files were being sent to a stand-alone console that was not being checked on a daily basis. As a result, the stated SLA for detection was exceeded. Which of the following is a way to prevent this delay in the future?
Answer: C
Explanation:
The issue was not that logs were unavailable, but that they were being sent to a stand-alone console that was not routinely monitored. A centralized dashboard improves visibility by aggregating logs and alerts into a single monitoring platform, making it more likely that security events are detected within the required SLA.
