                          HPE Networking Central Exam Sample Questions (Q68-Q73):

                          NEW QUESTION # 68
                          A retail stack must survive a member failure with minimal disruption. Which configuration in HPE Aruba Networking Central addresses this goal?

                          Answer: C

                          Explanation:
                          A VSX-based design with multiple members and MC-LAG provides high availability by maintaining independent control planes while ensuring active-active forwarding. This allows traffic to continue flowing with minimal disruption if one stack member fails, making it suitable for retail environments requiring resilient redundancy.


                          NEW QUESTION # 69
                          In cases where spanning tree protocols cannot be used to prevent loops at the edge of the network, which switch feature should you enable to avoid loops?

                          Answer: B

                          Explanation:
                          Technical explanation
                          Loop protection can emit and detect dedicated loop-detection frames on ports where spanning-tree participation is unavailable or inappropriate. When the device sees its loop-detection traffic return, it can disable or otherwise isolate the problem interface according to configured action and recovery behavior.
                          BPDU Guard requires reception of spanning-tree BPDUs; a loop formed between two ordinary edge ports or through a device that does not emit BPDUs can evade that trigger. Define recovery policy to avoid repeated flapping into an unresolved loop.
                          LACP bundles links but is not a general defense against accidental edge patch loops. BPDU Guard reacts to received BPDUs; a silent loop can bypass it. Loop protection tests for loopback behavior itself.

                          NEW QUESTION # 70
                          Which HPE Aruba Networking Central feature allows administrators to receive alerts and notifications about network issues?

                          Answer: C

                          Explanation:
                          The Alerts & Events Dashboard provides real-time visibility into network issues, alarms, and system-generated notifications. It helps administrators quickly identify and troubleshoot problems before they impact users.


                          NEW QUESTION # 71
                          How can you safely upgrade firmware across hundreds of APs while minimizing disruption?

                          Answer: B

                          Explanation:
                          Live Upgrade is an automated feature designed to minimize network downtime by orchestrating the firmware update process in a hitless manner. Instead of rebooting every access point at once, the system intelligently selects specific APs to upgrade while ensuring that neighboring APs remain active to handle client traffic. This rolling update approach maintains continuous wireless coverage across the campus, allowing the upgrade to proceed during active hours without causing a widespread loss of connectivity.


                          NEW QUESTION # 72
                          A pair of aggregation switches needs independent control planes and rapid recovery. Which deployment meets this requirement?

                          Answer: C

                          Explanation:
                          Technical explanation
                          VSX preserves independent control planes and distinct management endpoints for the two aggregation peers while coordinating shared L2 behavior and downstream multi-chassis LAGs. Test failures of the ISL, keepalive path and one switch separately, because their protective actions are not identical. Static routing between unrelated switches supplies reachability but not the paired logical aggregation capabilities requested.
                          VSF is suitable for a single-control-plane stack, but that is the opposite of the independent-control-plane design requirement. Split-brain handling, peer keepalive and ISL loss are distinct failure cases; the design review should document all three rather than assuming a single "core failed" test covers VSX behavior.
                          Static routes alone do not supply MC-LAG-like dual-attached switching, and VSF deliberately shares its stack control plane. VSX retains two independently managed systems and coordinates their high-availability role.
