Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) 200-201 Practice Test 24
Question 230
After the vulnerability management analyst at the telemedicine portal applies this approved action — Restrict negotiated TLS cipher suites to the current approved authenticated encryption and key-exchange profile. — the original issue is revisited: A server's advertised TLS suites include obsolete weak key-exchange modes that remain negotiable with legacy clients. Which measured result is the strongest evidence that this specific control or investigation objective has been met?
- The telemetry shows abnormal incomplete handshakes and the mitigation preserves ordinary connections.
- The correct sensitive export request is isolated from routine login requests.
- The test client negotiates an approved suite and a weak-suite-only client cannot complete negotiation.
- Only the two authorized target login failure variants match the corrected rule.
Explanation
Correct Answer
C:This outcome is the direct verification of the approved action: Restrict negotiated TLS cipher suites to the current approved authenticated encryption and key-exchange profile.

Question 231
An incident at the vendor access management console is escalated to a endpoint security engineer after incident-response triage reveals: A request is relayed through multiple permitted proxies, and analysts mistakenly claim the final proxy IP identifies the initial user. Correlate network records to the correct identity and time without revealing unrelated customers. Operations needs evidence that the proposed defense remains effective after a routine service restart. Which targeted defensive analysis or remediation action most directly addresses the stated failure while honoring the constraints?
- Correlate trusted proxy request identifiers and authorization logs through each forwarding hop.
- Use DNS, certificate, SNI where available, timing and endpoint logs; explicitly limit claims about encrypted payloads.
- Limit the host firewall rule to the jump-host source and expected management port with auditing enabled.
- Rank collection by volatility and business/legal constraints, including memory and live connections before persistent files where safe.
Explanation
Correct Answer
A:This action addresses the proxy chaining attribution issue in the vendor access management console, matching the observed mechanism rather than a different threat or tool.
