Cisco 300-710 Practice Test 19
Question 180
During a firewall implementation acceptance test: A cluster expansion introduces a node without confirming the platform's supported member and interface requirements. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Build a supported cluster with consistent member settings, control and data connectivity and platform-specific prerequisites.
- Inspect approved runbook, prechange snapshots, recovery access, lab cutover results and reachability tests after each step.
- Inspect cluster membership and roles, interface assignments, control link health and supported platform matrix.
- Assume any mix of firewall models can be clustered merely by attaching them to the same subnet.
- Configure supported equal-cost paths with appropriate next-hop health and ensure a stateful-inspection-compatible return design.
Explanation
Correct Answers
A:Appropriate implementation: Build a supported cluster with consistent member settings, control and data connectivity and platform-specific prerequisites. Case details: A cluster expansion introduces a node without confirming the platform's supported member and interface requirements. Governing behavior: Clustering coordinates multiple nodes for scalability or resiliency under documented platform constraints and is not identical to an active-standby HA pair.
C:Direct independent How to verify: Inspect cluster membership and roles, interface assignments, control link health and supported platform matrix.
Incorrect Answers
B:That option would inspect approved runbook, prechange snapshots, recovery access, lab cutover results and reachability tests after each step, but it addresses a different concern. Governing behavior: Clustering coordinates multiple nodes for scalability or resiliency under documented platform constraints and is not identical to an active-standby HA pair.
D:Unsafe or unsupported shortcut for this firewall scenario: Assume any mix of firewall models can be clustered merely by attaching them to the same subnet.
E:This alternative describes a different control, ECMP equal-cost multipath routing control, rather than this scenario’s Secure Firewall clustering control and data roles: Configure supported equal-cost paths with appropriate next-hop health and ensure a stateful-inspection-compatible return design.
Question 181
A CCNP Security practice scenario presents this condition: A firewall cluster loses one member and a portion of application flows fails because the design never tested ownership or rebalancing. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Assume a clustered security service retains full throughput after any number of member outages with no traffic impact.
- Verify HA configuration and policy synchronization, supported connection state preservation and peer software compatibility before change.
- Verify the chosen Threat Defense version and deployment mode support the proposed NAT and inspection features, then redesign and retest unsupported configurations.
- Plan staged member failure tests and supported connection ownership behavior, retaining sufficient capacity and recovery access.
Explanation
Correct Answer
D:Appropriate implementation: Plan staged member failure tests and supported connection ownership behavior, retaining sufficient capacity and recovery access.
Incorrect Answers
A:That option would assume a clustered security service retains full throughput after any number of member outages with no traffic impact, but it addresses a different concern. Governing behavior: Clustered traffic distribution and state handling depend on node roles, ownership rules and member health; a cluster is not immunity to capacity loss.
B:That option would verify HA configuration and policy synchronization, supported connection state preservation and peer software compatibility before change, but it addresses a different concern. Governing behavior: Clustered traffic distribution and state handling depend on node roles, ownership rules and member health; a cluster is not immunity to capacity loss.
C:That option would verify the chosen Threat Defense version and deployment mode support the proposed NAT and inspection features, then redesign and retest unsupported configurations, but it addresses a different concern. Governing behavior: Clustered traffic distribution and state handling depend on node roles, ownership rules and member health; a cluster is not immunity to capacity loss.
Question 182
A firewall service owner escalates the following: A firewall cluster loses one member and a portion of application flows fails because the design never tested ownership or rebalancing. Which firewall behavior or technical principle BEST explains the observed condition? Select ONE best answer.
- Deployment mode determines forwarding behavior and interface capabilities; transparent inspection is not interchangeable with a routed firewall topology.
- Clustered traffic distribution and state handling depend on node roles, ownership rules and member health; a cluster is not immunity to capacity loss.
- Assume a clustered security service retains full throughput after any number of member outages with no traffic impact.
- A port channel aggregates compatible physical links into a logical interface; one failed or mismatched member can reduce effective capacity or prevent bundling.
Explanation
Correct Answer
B:Underlying platform principle: Clustered traffic distribution and state handling depend on node roles, ownership rules and member health; a cluster is not immunity to capacity loss.
Incorrect Answers
A:This alternative describes a different control, Routed versus transparent insertion tradeoffs, rather than this scenario’s Cluster member failure and connection ownership: Deployment mode determines forwarding behavior and interface capabilities; transparent inspection is not interchangeable with a routed firewall topology.
C:Unsafe or unsupported shortcut for this firewall scenario: Assume a clustered security service retains full throughput after any number of member outages with no traffic impact. It cannot establish the stated security outcome.
D:This alternative describes a different control, LACP port channels and logical interfaces, rather than this scenario’s Cluster member failure and connection ownership: A port channel aggregates compatible physical links into a logical interface; one failed or mismatched member can reduce effective capacity or prevent bundling.
Question 183
An approved maintenance window surfaces this issue: A firewall cluster loses one member and a portion of application flows fails because the design never tested ownership or rebalancing. Which specific evidence is MOST useful to confirm the real root cause? Select ONE best answer.

Which observed result BEST confirms that the change meets the intended security requirement? Select ONE best answer.
- Assume a clustered security service retains full throughput after any number of member outages with no traffic impact.

C:This alternative describes a different control, Transparent firewall Layer 2 adjacency and MAC learning, rather than this scenario’s Cluster member failure and connection ownership: End hosts keep their intended gateway, frames traverse a single intended inspected path and MAC flapping stops.
Question 185
An FMC policy and traffic review discovers: A firewall cluster loses one member and a portion of application flows fails because the design never tested ownership or rebalancing. Which misleading assumption MOST directly causes this issue and must be rejected? Select ONE best answer.
- Assume a passive copy-based sensor can always drop the original attack packet or infer unmirrored return traffic.
- Assume a clustered security service retains full throughput after any number of member outages with no traffic impact.

Question 187
A security operations incident describes: During a clustered firmware change, engineers simultaneously remove multiple members without verifying remaining throughput. Which firewall behavior or technical principle BEST explains the observed condition? Select ONE best answer.
- Passive inspection sees replicated traffic outside the forwarding path and generally cannot directly prevent the original packets from arriving.
