Which two security mechanisms are used by Cisco Threat Defense to gain visibility into the most dangerous cyber threats? (Choose two.)

Virtual private networks (VPNs) provide secure, encrypted communication channels but are not primarily a mechanism for gaining visibility into threats within the encrypted traffic itself.

File reputation services analyze files against a vast database of known malicious content, signatures, and behaviors, allowing Cisco Threat Defense to identify and block malware or suspicious files effectively. This capability is crucial for detecting zero-day threats and advanced persistent threats.

VLAN segmentation isolates network traffic into different broadcast domains, enhancing security by limiting lateral movement but not directly providing threat visibility mechanisms.

Traffic Telemetry involves collecting and analyzing network flow data, metadata, and packet information to detect anomalies, suspicious communication patterns, and indicators of compromise. This provides extensive visibility into network activity, enabling early detection of malicious traffic and potential breaches.

Dynamic enforce policy refers to adaptive security policy application but is a control mechanism, not a specific mechanism for gaining threat visibility.
