Cisco 300-710 Practice Test 49
Question 480
A Secure Firewall deployment change request reports: An analyst labels an intrusion event as evidence of prevention despite the policy action permitting traffic to continue. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Assume any Snort intrusion alert always means the associated traffic was dropped before reaching the destination.
- Inspect DNS policy order, query events, resolver path and lookup outcomes for both blocked and approved domains.
- Select the appropriate rule or intrusion policy action for detection versus prevention and verify by controlled flows.
- Use supported application identification or custom detector methods based on recognizable traffic attributes and validate on controlled samples.
- Inspect effective intrusion action, relevant event disposition, packet capture and completion or reset of a controlled test session.
Explanation
Correct Answers
C:Appropriate implementation: Select the appropriate rule or intrusion policy action for detection versus prevention and verify by controlled flows. Case details: An analyst labels an intrusion event as evidence of prevention despite the policy action permitting traffic to continue. Governing behavior: Intrusion detection events and enforced packet drops are distinct outcomes; an alert can occur without blocking a session.
E:Direct independent How to verify: Inspect effective intrusion action, relevant event disposition, packet capture and completion or reset of a controlled test session.
Incorrect Answers
A:Unsafe or unsupported shortcut for this firewall scenario: Assume any Snort intrusion alert always means the associated traffic was dropped before reaching the destination.
B:That option would inspect DNS policy order, query events, resolver path and lookup outcomes for both blocked and approved domains, but it addresses a different concern. Governing behavior: Intrusion detection events and enforced packet drops are distinct outcomes; an alert can occur without blocking a session.
D:That option would use supported application identification or custom detector methods based on recognizable traffic attributes and validate on controlled samples, but it addresses a different concern. Governing behavior: Intrusion detection events and enforced packet drops are distinct outcomes; an alert can occur without blocking a session.
Question 481
An FMC policy and traffic review discovers: An administrator edits an access-control rule but users see old behavior because the change is saved in FMC and never deployed to the sensor. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Configure explicit dashboard widgets, filters, device scope and time windows and validate against raw events.
- Review deployment preview and per-device result, resolve failures and confirm the effective revision on the target Threat Defense device.
- Assume saving a rule in FMC instantaneously installs it on every managed device, including those reporting failed deployment.
- Use packet-path simulation to inspect translation, access rule, egress route and then independently test reverse traffic and peer availability.
Explanation
Correct Answer
B:Appropriate implementation: Review deployment preview and per-device result, resolve failures and confirm the effective revision on the target Threat Defense device.
Incorrect Answers
A:This alternative describes a different control, FMC dashboard data freshness and operational scope, rather than this scenario’s FMC device deployment job and configuration health: Configure explicit dashboard widgets, filters, device scope and time windows and validate against raw events.

Independent evidence: Inspect pending changes, deployment task details, target revision and a matched connection test on the affected firewall.
D:This alternative describes a different control, Packet Tracer NAT and route evaluation, rather than this scenario’s FMC device deployment job and configuration health: Use packet-path simulation to inspect translation, access rule, egress route and then independently test reverse traffic and peer availability.
Question 482
An engineer validates a Cisco Secure Firewall implementation: An administrator edits an access-control rule but users see old behavior because the change is saved in FMC and never deployed to the sensor.

- Low-level firewall diagnostics can reveal processing details but excessive debug may affect performance and produce misleading volume.
- Assume saving a rule in FMC instantaneously installs it on every managed device, including those reporting failed deployment.
