                          NEW QUESTION # 101
                          You must upgrade AP firmware across 40 sites with limited downtime. Which HPE Aruba Networking Central capability supports this plan?

                          Answer: B

                          Explanation:
                          Technical explanation
                          Firmware policy allows administrators to select devices by deployment scope, desired image and an upgrade mechanism. A live upgrade organizes participating APs into reboot sets rather than restarting the entire RF neighborhood together. Prechecks include supported AP hardware, appropriate licensing, access to image distribution and sufficient overlapping coverage. Schedule sites in controlled waves, observe client experience between waves and retain a backout plan. BIOS-dependent transitions and unsupported combinations may require a standard maintenance-window upgrade. For forty sites, stagger upgrade waves by RF coverage and criticality; avoid putting neighboring radios into the same reboot wave. Check the actual release supports the desired live-upgrade procedure for the APs involved.
                          Manually touching every AP multiplies administrative effort and risk across forty sites. An unscheduled global push can take adjacent radios offline together. A planned live-upgrade sequence is designed to preserve coverage while individual APs change software.

                          NEW QUESTION # 102
                          A site requires a common syslog target and NTP server for all switches. Which HPE Aruba Networking Central configuration approach reduces duplicated effort?

                          Answer: C

                          Explanation:
                          Defining shared NTP and syslog-related settings at the site level in HPE Aruba Networking Central ensures consistent configuration across all switches within that site while avoiding repetitive per-device configuration. Site-level profiles are designed for common services like time synchronization and logging targets, improving operational efficiency and standardization.


                          NEW QUESTION # 103
                          Which HPE Aruba Networking Central feature provides RF management?

                          Answer: C

                          Explanation:
                          Technical explanation
                          AirMatch is the Central-hosted RF optimization service that computes channel, bandwidth and EIRP plans from aggregated radio telemetry. It can optimize neighboring radios together rather than having each AP operate on purely local observations. The service normally calculates scheduled improvements and can react to urgent RF events, subject to regulatory channel constraints and deployment settings. ARM is an earlier local RF-management approach, while ClientMatch primarily addresses client-to-AP association and steering rather than the overall channel/power plan.
                          ARM is the legacy/local RF adjustment concept, while ClientMatch steers associations among available APs.
                          AirMatch plans channels, channel widths, and transmit powers using network-wide conditions; that is the AOS-10 RF management component.

                          NEW QUESTION # 104
                          A user's role should restrict access to internal resources but allow internet access. Which policy configuration enforces this?

                          Answer: C

                          Explanation:
                          Aruba policies operate on a "first-match" principle, meaning the switch or gateway processes rules sequentially from top to bottom. To effectively restrict access to internal resources while allowing everything else (like the internet), the restrictive rule must be placed at the beginning of the policy. If the restriction were at the end, a more general "allow" rule might trigger first, inadvertently permitting access to the internal network before the "deny" rule is ever reached.
                          This ensures the security boundary is checked before any broader permissions are granted.


                          NEW QUESTION # 105
                          Which design ensures continuous WLAN coverage if an AP fails?

                          Answer: B

                          Explanation:
                          Deploying Access Points with overlapping coverage zones (typically 15% to 20% overlap) is the fundamental principle of high-availability wireless design. If a single AP fails, the neighboring APs are positioned close enough to provide a usable signal to the area previously served by the failed device. This prevents "dead zones" and allows client devices to roam to a healthy AP without losing connectivity.
