Cisco 300-710 Practice Test 63
Question 620
During a firewall implementation acceptance test: A malware alert references a file hash from an earlier transfer, while a dashboard presents it as if it happened in the current hour. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Capture packets at the relevant supported ingress and egress points with bounded filter, direction and retention settings.
- Assume every high-severity intrusion or malware alert conclusively proves an attacker executed code on the destination host.
- Inspect event signature, action, file hash or disposition, host identity, source telemetry and correlated endpoint evidence.
- Review intrusion or malware details, signatures or file disposition, time and asset context before declaring impact.
- Review report definition, recipient list, last-generation timestamp, source events and a controlled delivered report.
Explanation
Correct Answers
C:Direct independent How to verify: Inspect event signature, action, file hash or disposition, host identity, source telemetry and correlated endpoint evidence.
D:Appropriate implementation: Review intrusion or malware details, signatures or file disposition, time and asset context before declaring impact. Case details: A malware alert references a file hash from an earlier transfer, while a dashboard presents it as if it happened in the current hour. Governing behavior: Severity and detection labels convey prioritization or engine verdict, not independent proof of host compromise or successful execution.
Incorrect Answers
A:This alternative describes a different control, FMC packet capture ingress and egress placement, rather than this scenario’s Intrusion and malware event severity interpretation: Capture packets at the relevant supported ingress and egress points with bounded filter, direction and retention settings.
B:Unsafe or unsupported shortcut for this firewall scenario: Assume every high-severity intrusion or malware alert conclusively proves an attacker executed code on the destination host.
E:That option would review report definition, recipient list, last-generation timestamp, source events and a controlled delivered report, but it addresses a different concern. Governing behavior: Severity and detection labels convey prioritization or engine verdict, not independent proof of host compromise or successful execution.
Question 621
A CCNP Security practice scenario presents this condition: A newly discovered host is presented as a critical production server although the system fingerprint is stale from a prior DHCP client. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Assume a discovery map is always a real-time authoritative list of every asset on every network.
- Use documented narrowly filtered firewall engine debug only when necessary and capture enough context to explain the actual drop.
- Cross-check discovery inventory and network map against current authoritative ownership, addresses and monitored traffic coverage.
- Use packet-path simulation to inspect translation, access rule, egress route and then independently test reverse traffic and peer availability.
Explanation
Correct Answer
C:Appropriate implementation: Cross-check discovery inventory and network map against current authoritative ownership, addresses and monitored traffic coverage.
Incorrect Answers
A:That option would assume a discovery map is always a real-time authoritative list of every asset on every network, but it addresses a different concern. Governing behavior: Asset maps depend on discovery telemetry, IP reuse and monitoring scope and may not represent a live complete inventory.

Governing behavior: Asset maps depend on discovery telemetry, IP reuse and monitoring scope and may not represent a live complete inventory.
D:That option would use packet-path simulation to inspect translation, access rule, egress route and then independently test reverse traffic and peer availability, but it addresses a different concern. Governing behavior: Asset maps depend on discovery telemetry, IP reuse and monitoring scope and may not represent a live complete inventory.
Question 622
A firewall service owner escalates the following: A newly discovered host is presented as a critical production server although the system fingerprint is stale from a prior DHCP client. Which firewall behavior or technical principle BEST explains the observed condition? Select ONE best answer.
- Assume a discovery map is always a real-time authoritative list of every asset on every network.
- Simulated policy allow can verify configured local processing but not remote application response or the external network's actual state.
- Management-plane enrollment and telemetry can fail while data-plane forwarding continues, and troubleshooting must identify the affected plane.
- Asset maps depend on discovery telemetry, IP reuse and monitoring scope and may not represent a live complete inventory.
Explanation
Correct Answer
D:Underlying platform principle: Asset maps depend on discovery telemetry, IP reuse and monitoring scope and may not represent a live complete inventory.
Incorrect Answers
A:Unsafe or unsupported shortcut for this firewall scenario: Assume a discovery map is always a real-time authoritative list of every asset on every network. It cannot establish the stated security outcome.
B:This alternative describes a different control, Packet Tracer NAT and route evaluation, rather than this scenario’s Network discovery map and asset context validation: Simulated policy allow can verify configured local processing but not remote application response or the external network's actual state.
C:This alternative describes a different control, Management communication and FTD registration troubleshooting, rather than this scenario’s Network discovery map and asset context validation: Management-plane enrollment and telemetry can fail while data-plane forwarding continues, and troubleshooting must identify the affected plane.
Question 623

Which observed result BEST confirms that the change meets the intended security requirement? Select ONE best answer.
- The root-causing change is identified and corrected with a traceable audit and no new unexplained policy drift.
- The response gathers sufficient network evidence without unsupported plaintext claims or excessive capture storage and privacy impact.
- Assume a discovery map is always a real-time authoritative list of every asset on every network.
- Investigators use current corroborated asset context and explicitly acknowledge unmonitored segments or uncertainty.
Explanation
Correct Answer
D:Required acceptance evidence: Investigators use current corroborated asset context and explicitly acknowledge unmonitored segments or uncertainty.
Incorrect Answers
A:This alternative describes a different control, Policy revision rollback and controlled troubleshooting, rather than this scenario’s Network discovery map and asset context validation: The root-causing change is identified and corrected with a traceable audit and no new unexplained policy drift.

Question 625
An FMC policy and traffic review discovers: A newly discovered host is presented as a critical production server although the system fingerprint is stale from a prior DHCP client. Which misleading assumption MOST directly causes this issue and must be rejected? Select ONE best answer.
- Assume saving a rule in FMC instantaneously installs it on every managed device, including those reporting failed deployment.
- Assume scheduling a report automatically keeps its recipient list, asset inventory and data range accurate indefinitely.
- Assume a discovery map is always a real-time authoritative list of every asset on every network.
- Assume every unified event entry is a distinct confirmed incident regardless of underlying source overlap.
