Question 630
A firewall service owner escalates the following: An incident map omits a disconnected subnet and a report incorrectly states the network has no devices there. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Cross-check discovery inventory and network map against current authoritative ownership, addresses and monitored traffic coverage.
- Inspect host history, IP-to-MAC transitions, last-seen fields, subnets monitored and inventory records.
- Inspect matched policy, initiator and responder addresses, bytes and disposition plus reverse-flow captures.
- Use packet-path simulation to inspect translation, access rule, egress route and then independently test reverse traffic and peer availability.
- Assume a discovery map is always a real-time authoritative list of every asset on every network.
Explanation
Correct Answers
A:Appropriate implementation: Cross-check discovery inventory and network map against current authoritative ownership, addresses and monitored traffic coverage. Case details: An incident map omits a disconnected subnet and a report incorrectly states the network has no devices there. Governing behavior: Asset maps depend on discovery telemetry, IP reuse and monitoring scope and may not represent a live complete inventory.
B:Direct independent How to verify: Inspect host history, IP-to-MAC transitions, last-seen fields, subnets monitored and inventory records.
Incorrect Answers
C:That option would inspect matched policy, initiator and responder addresses, bytes and disposition plus reverse-flow captures, 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.
D:This alternative describes a different control, Packet Tracer NAT and route evaluation, rather than this scenario’s Network discovery map and asset context validation: Use packet-path simulation to inspect translation, access rule, egress route and then independently test reverse traffic and peer availability.
E: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.
Question 631
An approved maintenance window surfaces this issue: A unified event list merges several alert types for one host and a team counts each row as a separate confirmed security breach. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Assume every unified event entry is a distinct confirmed incident regardless of underlying source overlap.
- Review deployment preview and per-device result, resolve failures and confirm the effective revision on the target Threat Defense device.
- Correlate event families, asset identities, timestamps and source coverage before interpreting unified risk patterns.
- Use packet-path simulation to inspect translation, access rule, egress route and then independently test reverse traffic and peer availability.
Explanation

Question 635
A security operations incident describes: A unified event list merges several alert types for one host and a team counts each row as a separate confirmed security breach. Which misleading assumption MOST directly causes this issue and must be rejected? Select ONE best answer.
- Assume a local packet-tracer final allow verdict guarantees the remote application can respond successfully.
- Assume every unified event entry is a distinct confirmed incident regardless of underlying source overlap.
