Question 320
During a staged rollout, the team needs to send web events through a customer-hosted streaming relay to a private collector. Which approach is the best fit for this purpose?
Explanation
Correct Answer
ZIA VM NSS on-prem SIEM is appropriate because VM-based NSS receives cloud Nanolog data and forwards filtered output to the SIEM. That directly serves the stated need to send web events through a customer-hosted streaming relay to a private collector. Its boundary is that the collector protocol and feed filtering must match the receiving parser.
Incorrect Answers
ZPA LSS receiver integration is used to correlate private-app access and App Connector status outside the ZPA console. It works because LSS forwards supported ZPA diagnostics to an external log receiver, but does not directly implement the named need for ZIA VM NSS on-prem SIEM.
Incident correlation by identity is used to join permitted security events across ZIA and ZPA in an enterprise analytics workflow. It works because shared user and time fields can support correlation between web and private-app activity, but does not directly implement the named need for ZIA VM NSS on-prem SIEM.
ZIA Cloud NSS HTTPS collector is used to send selected ZIA security logs to a cloud SIEM ingestion endpoint. It works because cloud NSS can deliver selected supported log types over HTTPS to a compatible collector, but does not directly implement the named need for ZIA VM NSS on-prem SIEM.
