Exam 350-401 topic 1 question 269 discussion

Stealthwatch collects telemetry from every part of the network and applies advanced security analytics to the data. It creates a baseline of normal web and network activity for a network host, and applies context-aware analysis to automatically detect anomalous behaviors.

The given solution is correct

B is correct

Stealthwatch is now a deprecated name, as the 1.1 OCG points out it is now called Cisco Secure Network Analytics. "Cisco Secure Network Analytics, formerly Stealthwatch Enterprise, is a collector and aggregator of network telemetry data..." Similarly, Stealthwatch Cloud is now Cisco Secure Cloud Analytics. However, past experience has shown that questions like this WILL still be asked using the old terms, so knowing the answer is B here is still useful.

Of course B is right from OCG Cisco Stealthwatch is a collector and aggregator of network telemetry data that performs network security analysis and monitoring to automatically detect threats that manage to infiltrate a network as well as the ones that originate from within a network.

Given answer is correct. https://www.cisco.com/c/dam/en/us/td/docs/security/network_security/ctd/ctd2-0/design_guides/ctd_2-0_cvd_guide_jul15.pdf Page 4.
