Question 180
After the endpoint security engineer at the remote industrial maintenance site applies this approved action — Remove unnecessary public listeners and allow approved management access through restricted administrative paths. — the original issue is revisited: A service publishes SSH, database, and HTTP ports publicly although customers only require HTTPS. Which measured result is the strongest evidence that this specific control or investigation objective has been met?
- External probes reach only intended HTTPS while authorized restricted management remains available.
- The telemetry shows abnormal incomplete handshakes and the mitigation preserves ordinary connections.
- The case contains the anomalous transfer metrics and confirmed destination ownership before incident classification.
- The base-score explanation records the unusual timing condition and applies the corresponding complexity criterion.
Explanation
Correct Answer
A:This outcome is the direct verification of the approved action: Remove unnecessary public listeners and allow approved management access through restricted administrative paths. It proves the corrective or detection objective through observed evidence, not simply because a rule was saved or an alarm was acknowledged.
Incorrect Answers
B:This observation validates another tcp syn flood indicators issue and the corrective action Correlate SYN/SYN-ACK completion, source dispersion and edge resource metrics to classify a suspected SYN flood.

Question 181
An incident at the identity federation production tenant is escalated to a host incident responder after forensic evidence quality assessment reveals: A malicious document requires a user to open it, but the incident team treats it as a zero-click network flaw. Do not treat a healthy dashboard status as proof of the required security property. A limited change window is approved, with a prechange reference, a tested rollback and a negative control action. Which targeted defensive analysis or remediation action most directly addresses the stated failure while honoring the constraints?
- Mark user interaction according to the necessary victim action and document the observed click or open trigger.
- Use approved agent-based runtime telemetry for process-level evidence and retain agentless assessment for scheduled configuration coverage.
- Treat a nontriggered detonation as limited observation and correlate static clues and environment requirements.
- Classify the record as flow/transaction summary telemetry and preserve limits on missing payload visibility.
Explanation
Correct Answer
A:This action addresses the cvss user interaction issue in the identity federation production tenant, matching the observed mechanism rather than a different threat or tool. The acceptance test must demonstrate: The score captures the requirement for a user action rather than an unattended exploit.

Question 183
After the security monitoring architect at the vendor access management console applies this approved action — Publish a response plan defining roles, escalation paths, decision authority, contact methods and evidence responsibilities. — the original issue is revisited: A ransomware alert arrives outside office hours and analysts cannot identify who may authorize network isolation or customer notifications. Which measured result is the strongest evidence that this specific control or investigation objective has been met?
- A bounded report identifies the abnormal byte-rate and its exact destination without relying on one sampled packet.
- A tabletop event reaches the authorized decision maker and produces a logged containment decision.
- The analysis correctly identifies the true destination domain despite the brand word in the URL path.
- The event sequence aligns correctly across both logs and preserves original timestamps for audit.
Explanation
Correct Answer

Question 185
A vulnerability management analyst at the telemedicine portal investigates during postincident evidence review: A server's advertised TLS suites include obsolete weak key-exchange modes that remain negotiable with legacy clients. Keep packet collection within the approved scope and do not assume encrypted payloads are readable. The team compares the result to a known-good baseline from another authorized system, and records the source clock offset. This alternate observation is collected from a second routed segment with different sensor coverage and timestamped NAT mappings; preserve raw flow direction and explicitly label whether application data or only transport metadata was available. Which targeted defensive analysis or remediation action most directly addresses the stated failure while honoring the constraints?
- Use timestamped NAT translation records with flow tuples to recover the original internal client identity.
- Distinguish SYN, SYN-ACK, ACK, FIN and RST states when evaluating connection establishment.
- Score remediation priority using asset value, exposure, likelihood and business impact instead of technical severity alone.
- Restrict negotiated TLS cipher suites to the current approved authenticated encryption and key-exchange profile.
Explanation
Correct Answer
D:This action addresses the cipher suite selection issue in the telemedicine portal, matching the observed mechanism rather than a different threat or tool.
