Cisco 300-220 Exam Dumps - Actual Questions Answers

The correct answer isit reflects the attacker’s operational preferences. Attribution relies on understandinghow attackers operate, not just what tools they use.

Operational preferences—such as avoiding PowerShell logging, disabling AMSI, and favoring WMI—arebehavioral signatures. These patterns often persist across campaigns and are documented in threat intelligence reports associated with specific adversaries.

Option A is incorrect because malware families change frequently. Option B is unreliable due to infrastructure rotation. Option D is unrelated to post-access tradecraft.

Professional attribution focuses on:

Execution methods

Defensive evasion choices

Tooling preferences

Workflow consistency

Mapping these behaviors toMITRE ATT&CK techniquesenables analysts to compare findings against known threat actor profiles. This provides higher confidence attribution than artifact-based indicators.

Thus, optionCis the correct answer.

The correct answer isDiscovery of unknown attacker behaviors and closure of detection gaps. This outcome best reflects thestrategic valueof threat hunting beyond incident response.

Threat hunting is not primarily about cleanup actions such as credential resets or file removal—those areincident response tasks. The real value of hunting lies in uncoveringpreviously undetected attacker behaviors, understanding how adversaries bypass controls, and translating those findings intoimproved detection and prevention.

Option A represents low-value indicators that attackers can easily change. Option C assumes malware was involved, which is not the case. Option D is necessary but tactical, not strategic.

By identifying credential misuse patterns, lateral movement paths, and data exfiltration techniques, the team can:

Create new SIEM and EDR detections

Harden identity and access controls

Reduce dwell time for future intrusions

Force attackers higher up the Pyramid of Pain

This demonstratesorganizational resilience, not just containment. Mature security programs measure success by how effectively theyeliminate blind spots, not how many alerts they close.

Thus, optionBis the correct answer.

The correct answer isThey produce false positives and false negatives. Automated dynamic malware analysis tools, such as sandboxes, execute suspicious files in isolated environments to observe runtime behavior. While these tools are extremely valuable in modern SOCs, they are not infallible and have well-known limitations.

False positives occur when benign software exhibits behaviors that resemble malicious activity, such as creating registry keys, spawning child processes, or making network connections. Conversely, false negatives occur when malware intentionallyevades detectionby altering its behavior. Many modern malware samples include sandbox evasion techniques such as checking for virtualized environments, delaying execution, requiring user interaction, or disabling malicious functionality when analysis artifacts are detected.

Option A is incorrect because dynamic analysis can, in fact, uncover runtime vulnerabilities and exploit behavior. Option C is misleading; while tooling coverage varies, language support is not the primary limitation. Option D refers tomanual analysis, whereas the question explicitly addresses automated tools.

From a threat hunting and malware analysis standpoint, professionals understand that sandbox results must becorrelated with other telemetry, including endpoint behavior, network traffic, and threat intelligence. Automated tools are best used as part of a layered analysis strategy, not as a single source of truth.

This limitation reinforces a core security principle:automation accelerates detection, but human judgment validates impact. Skilled analysts interpret sandbox results, investigate anomalies, and determine real-world risk. Understanding the strengths and weaknesses of dynamic analysis tools allows SOC teams to avoid overreliance on automation while still benefiting from its speed and scale.
