Question 200
A Secure Firewall deployment change request reports: A team repeatedly forces failback to its preferred member during an incident, causing connection churn. Which THREE complementary elements form the corrective action, diagnostic proof and successful acceptance outcome? Select THREE answers.
- Configure Layer 3 interfaces, appropriate security zones and forward and return routing, then deploy the intended policy after validating topology.
- Verify partner synchronization and health, follow supported phased upgrade and failback procedures and monitor critical sessions.
- Review logical packet path, appliance mode, interface fail-open or bypass support and controlled downtime tests.
- Assume standby status alone proves a peer can safely take over any workload during an unplanned upgrade.
- The pair returns to the approved software and role configuration with bounded service disruption and documented rollback readiness.
- Inspect prechange HA state, release compatibility, last policy deployment, upgrade sequence and application transaction tests.
Explanation
Correct Answers
B:Appropriate implementation: Verify partner synchronization and health, follow supported phased upgrade and failback procedures and monitor critical sessions. Case details: A team repeatedly forces failback to its preferred member during an incident, causing connection churn. Approved action: Verify partner synchronization and health, follow supported phased upgrade and failback procedures and monitor critical sessions.
E:Required acceptance evidence: The pair returns to the approved software and role configuration with bounded service disruption and documented rollback readiness. Case details: A team repeatedly forces failback to its preferred member during an incident, causing connection churn. Approved action: Verify partner synchronization and health, follow supported phased upgrade and failback procedures and monitor critical sessions.
F:Direct independent How to verify: Inspect prechange HA state, release compatibility, last policy deployment, upgrade sequence and application transaction tests.
Incorrect Answers
A:That option would configure Layer 3 interfaces, appropriate security zones and forward and return routing, then deploy the intended policy after validating topology, but it addresses a different concern. Governing behavior: Planned HA maintenance must account for role transitions, software compatibility and traffic-state continuity rather than simply rebooting nodes.
C:That option would review logical packet path, appliance mode, interface fail-open or bypass support and controlled downtime tests, but it addresses a different concern. Governing behavior: Planned HA maintenance must account for role transitions, software compatibility and traffic-state continuity rather than simply rebooting nodes.
D:Unsafe or unsupported shortcut for this firewall scenario: Assume standby status alone proves a peer can safely take over any workload during an unplanned upgrade. Case details: A team repeatedly forces failback to its preferred member during an incident, causing connection churn. Governing behavior: Planned HA maintenance must account for role transitions, software compatibility and traffic-state continuity rather than simply rebooting nodes.
Question 201
An FMC policy and traffic review discovers: A Threat Defense virtual appliance boots on a hypervisor but its data-plane vNIC connects to the wrong virtual switch and cannot inspect intended tenant traffic. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Connect a supported passive sensing interface to an accurately configured mirror or TAP feed and validate observed directional coverage.

An engineer validates a Cisco Secure Firewall implementation: A Threat Defense virtual appliance boots on a hypervisor but its data-plane vNIC connects to the wrong virtual switch and cannot inspect intended tenant traffic. Which firewall behavior or technical principle BEST explains the observed condition? Select ONE best answer.
