HPE7-A07 Exam Dumps - HP Aruba Certified Professional - Campus Access Questions and Answers

The Aruba AP-615 is a tri-band Wi-Fi 6E access point, capable of operating on the 2.4 GHz, 5 GHz, and 6 GHz bands. However, in the default configuration, Aruba AP-615 radios operate in dual-band mode (2.4 GHz and 5 GHz).

The 6 GHz radio (the “E” band for Wi-Fi 6E) remains disabled by default until explicitly enabled by configuration through the ArubaOS or Aruba Central interface.

According to the Aruba Access Point Configuration Guide and Wi-Fi 6E Deployment Guide:

“Tri-band APs such as the AP-615 support operation in 2.4GHz, 5GHz, and 6GHz frequency bands. By default, the AP operates in dual-band mode (2.4GHz and 5GHz). The 6GHz band must be explicitly enabled by configuring the radio profile to tri-band mode.”

Thus, when a tri-band SSID is created without explicitly modifying the radio band configuration, the AP-615 continues to use 2.4GHz and 5GHz by default.

Option Analysis:

A. Incorrect – The 6GHz radio is not enabled by default.

B. Correct – Default operation is on the 2.4GHz and 5GHz bands.

C. Incorrect – 6GHz is only enabled through manual configuration.

D. Incorrect – While partially true, the question specifies default tri-band SSID behavior, which defaults to 2.4GHz and 5GHz.

Final Verified Answer: B

AOS-CX BGP community advertisement control:

“For each BGP neighbor and address-family you can control the advertisement of community attributes using the send-community command. The options are standard, extended, and both. When both is configured, the neighbor is sent both the standard and extended community attributes with the NLRI updates.”

“BGP accepts community attributes received from a neighbor by default; the send-community setting governs outbound advertisement. The configuration does not require resetting the peering session.”

These extracts establish that adding send-community both under the IPv4 unicast address-family for neighbor 10.2.0.3 makes R1 include community attributes with its UPDATEs and that the choice both covers standard and extended communities. Because BGP already accepts communities on receive, this effectively enables the exchange of communities in both directions when the peer is similarly capable. This matches B (exchange with NLRI in and out) and D (standard and extended communities are included).

Why A is incorrect:

“The term type-1/type-2 is used in EVPN route types and is not the nomenclature for BGP communities. The send-community command does not reference EVPN route types; it controls standard/extended community attributes.”

Thus, A references the wrong concept.

Why C is incorrect:

“Changing send-community for a neighbor is applied dynamically in the address-family context and does not require tearing down the BGP session.”

Therefore, enabling send-community both will not “bounce” the peering.

USB dongles often require additional power, which may exceed the power delivery capabilities of Class 4 PoE switches. Aruba AP-615 and AP-635 are designed to work with USB dongles that require additional power for proper operation. Since the Cat 6A cable can support higher power levels, replacing the Class 4 PoE switches with Class 6 PoE switches, which can deliver higher power, should resolve the issue with the dongles not powering up.

In a packet capture from an upstream switch port mirror, you would see the VLAN assignment. The port mirror captures the traffic as it is on the network, including any VLAN tags. GRE or IPsec tunnels encapsulate the original packet, including VLAN tags, but the VLAN information is not visible within the encapsulation headers.

On Aruba CX, LAG members must be link compatible (same speed/duplex and L2 characteristics). If one AP uplink (e0) negotiates SmartRate (e.g., 2.5/5 GbE) while the other (e1) negotiates 1 GbE, the switch detects the speed mismatch between the two member links and will not place both links in the distributing state. The second link is held in lacp-block to prevent forwarding on an incompatible member.

LACP active/passive (Option A) would affect whether a bundle forms at all, not cause lacp-block on just one member.

Routed-only interfaces (Option B) would prevent L2 aggregation entirely, not partially form with one member blocked.

Spanning tree/loop protect (Option C) do not produce an LACP member state of lacp-block.

Therefore, mixing a SmartRate port with a non-SmartRate port in the same LAG is the cause of the lacp-block state.

Option A includes all necessary steps for a full setup of an AOS 10 mobility gateway cluster, including setting the system name, switch role, ACP FQDN address, uplink port information, IP address and default gateway, DNS IP address, controller country code, timezone and clock, and admin password. Since the gateways must have static IP addresses and can only communicate on port 443 for a specific URL, this configuration would need to allow for static IP configuration and restrict communication to the required URL.

Adding an additional IP subnet to the same VLAN means that devices configured with either subnet can communicate at Layer 2 without the need for routing. This is because they are on the same VLAN and thus in the same broadcast domain. However, to communicate between subnets, an L3 device or inter-VLAN routing would be required.

The exhibit shows that the SSID supports 802.11ax clients, which is indicated by the presence of HT (High Throughput) information, VHT (Very High Throughput) capabilities, and HE (High-Efficiency) operation, which are all features associated with 802.11ax, also known as Wi-Fi 6.

The CLI output indicates a tunnel creation process, where "SW hw tun created" refers to the switch hardware tunnel being created. The line mentioning "BYP-10.10.10.101 -> SW hw tun created to 10.10.10.151 tunnel 15." implies that a tunnel was established to the secondary tunnel endpoint with the IP address 10.10.10.151. This is a common configuration for User-Based Tunneling (UBT) setups where traffic is tunneled to a specific endpoint.

The CLI output displays EVPN routes and their corresponding next hops. The "Route Distinguisher" entries followed by IP addresses in the 172.21.11.x range indicate these are loopback addresses used by the underlay network. The underlay network provides the basic routing and forwarding plane for the overlay network that EVPN is part of. These loopback addresses are crucial for the proper functioning of the EVPN control plane.
