350-401 Question #546: Real Exam Question with Answer & Explanation

Question

Which technology uses network traffic telemetry, contextual information, and file reputation to provide insight into cyber threats?

Options

• Athreat defense
• Bsecurity services
• Csecurity intelligence
• Dsegmentation

Explanation

Threat Defense is the correct answer because it is a comprehensive security approach that combines network traffic telemetry (real-time data collection and analysis of network flows), contextual information (user, device, and application context), and file reputation (known good/bad file classifications) to deliver actionable insights into cyber threats - this is a core capability of platforms like Cisco's Firepower Threat Defense (FTD).

Why the distractors are wrong:

• B. Security services is a broad, generic term referring to any security-related offerings (firewalls, VPNs, etc.) and does not specifically describe this telemetry-driven threat insight capability.
• C. Security intelligence refers specifically to feeds of known malicious IP addresses, URLs, and domains used to block threats at the access layer - it is a component of threat defense, not the umbrella technology described.
• D. Segmentation is a network design strategy that divides networks into zones to limit lateral movement, and has no direct relationship to telemetry or file reputation analysis.

Memory tip: Think of Threat Defense as the "big picture" security technology - it defends by actively analyzing traffic + context + reputation together. If a question mentions all three of those data sources working in combination, think "Threat Defense" as the overarching solution.
