NEW QUESTION # 65
Users report intermittent drops on the corporate SSID. Which HPE Aruba Networking Central tool helps isolate authentication failures?
Answer: C
Explanation:
The Client Event log provides detailed authentication and association history for individual clients, including failures, reauthentication attempts, and disconnect reasons. This makes it the most effective tool for isolating intermittent SSID drops caused by authentication issues.
NEW QUESTION # 66
HPE Aruba Networking Central reports that several switches are out of firmware compliance.
Which action ensures all sites meet the standard version?
Answer: A
Explanation:
A firmware policy at the Global scope ensures consistent enforcement of the desired firmware version across all sites and devices. This central policy-driven approach allows HPE Aruba Networking Central to continuously assess compliance and guide or automate upgrades so that all switches align with the defined standard version.
NEW QUESTION # 67
You want to prevent edge ports from creating loops if patched together. Which protection should you enable?
Answer: A
Explanation:
Technical explanation
BPDU Guard is appropriate on edge interfaces that should never receive spanning-tree bridge protocol data units. If somebody connects a downstream switch or another bridge that sends a BPDU, the guard transitions the port to a protected state, limiting a potential topology disturbance. It does not detect every possible loop between ordinary ports when no BPDU is emitted; loop protection or storm control may also be required. Do not enable edge BPDU Guard on legitimate switch-to-switch uplinks.
BPDU Filter suppresses information STP needs, potentially hiding a loop. Root Guard protects bridge-root selection on specified ports, not arbitrary edge patching. BPDU Guard disables an unexpected bridge-facing edge port when a BPDU appears.

NEW QUESTION # 68
You need to define DHCP relay settings for multiple VLANs across all access switches. Which configuration method is the most efficient?
Answer: A
Explanation:
Technical explanation
A VLAN profile allows DHCP helper-address configuration to follow the VLAN's Layer 3 interface requirements rather than attaching IP relay settings to an unrelated physical access port. Ensure that an SVI exists and has Layer 3 reachability to the DHCP server; DHCP relay is meaningful on the routing device that receives the broadcast. Scope the VLAN profile to the intended site and device functions and check whether any switch needs a unique local SVI address. Validate that both request and reply traffic can traverse the VRF and ACL policies. The VLAN profile workflow starts at Configuration > VLANs & Networks > VLAN > Create Profile, with the desired scope and switch function selected.
A port profile describes physical or logical interface attributes, not VLAN-specific relay across all switches.
A generic System profile does not replace the VLAN/SVI-facing helper relationship; tie the helper to the routed VLAN at the intended scope. Be precise about the Layer 3 termination: DHCP relay runs where the client VLAN broadcast reaches a routed VLAN interface. Defining a helper on a switch that only transports the VLAN at Layer 2 will not relay those broadcasts.

NEW QUESTION # 69
Per the "Rule of Threes," what does a 3 dBm increase correspond to?
Answer: D
Explanation:
Technical explanation
The rule is a logarithmic shortcut. A 3 dB gain multiplies linear power by 10
