Cisco 300-710 Practice Test 4
Question 30
A firewall service owner escalates the following: A campus firewall has multiple external interfaces but a rule tied to one unrelated interface zone accidentally permits the wrong path. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Place the inline NGIPS interface pair directly in the intended traffic path and confirm bidirectional inspection and policy behavior.
- Assume every interface name automatically creates the correct security-zone mapping for all inherited access rules.
- Inspect aggregation state, LACP neighbor and member state, physical counters and controlled flow load across the bundle.
- Map the actual interface or logical segment into the intended security zone and use verified source and destination zones in access-control policy.
- Review configured interface-to-zone membership, deployed access rules, input and output interfaces in connection events and representative packet decisions.
Explanation
Correct Answers
D:Appropriate implementation: Map the actual interface or logical segment into the intended security zone and use verified source and destination zones in access-control policy. Case details: A campus firewall has multiple external interfaces but a rule tied to one unrelated interface zone accidentally permits the wrong path. Governing behavior: Security zones are logical interface groupings used by policy matching, and changing a label alone does not reliably put traffic into a matching zone.
E:Direct independent How to verify: Review configured interface-to-zone membership, deployed access rules, input and output interfaces in connection events and representative packet decisions.
Incorrect Answers
A:This alternative describes a different control, NGIPS inline interface pair placement, rather than this scenario’s Security zones for routed and transparent contexts: Place the inline NGIPS interface pair directly in the intended traffic path and confirm bidirectional inspection and policy behavior.
B:Unsafe or unsupported shortcut for this firewall scenario: Assume every interface name automatically creates the correct security-zone mapping for all inherited access rules.
C:That option would inspect aggregation state, LACP neighbor and member state, physical counters and controlled flow load across the bundle, but it addresses a different concern. Governing behavior: Security zones are logical interface groupings used by policy matching, and changing a label alone does not reliably put traffic into a matching zone.
Question 31
An approved maintenance window surfaces this issue: An operations team wants to inspect traffic without changing endpoint gateways, but its proposed routed insertion would require new Layer 3 adjacencies. 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.
- Treat routed and transparent modes as identical choices that can be swapped without revisiting topology or access policy.
- Choose routed or transparent deployment based on whether the firewall must act as a Layer 3 hop or preserve an existing Layer 2 path, then validate the resulting traffic route.
- Place the inline NGIPS interface pair directly in the intended traffic path and confirm bidirectional inspection and policy behavior.
Explanation
Correct Answer
C:Appropriate implementation: Choose routed or transparent deployment based on whether the firewall must act as a Layer 3 hop or preserve an existing Layer 2 path, then validate the resulting traffic route.

Question 32
A Secure Firewall deployment change request reports: An operations team wants to inspect traffic without changing endpoint gateways, but its proposed routed insertion would require new Layer 3 adjacencies.
