Aruba Certified Campus Access Professional

To onboard a new UXI in an existing environment with 802.1X authentication, you need to use the UXI app on your smartphone and connect the UXI via Bluetooth. The UXI app allows you to scan the QR code on the UXI sensor and configure its network settings, such as SSID, password, IP address, etc. The Bluetooth connection allows you to communicate with the UXI sensor without requiring any network access or cellular connection. The other options are incorrect because they either do not use the UXI app or do not use Bluetooth.

Opportunistic Wireless Encryption (OWE) is a feature that provides encryption for open wireless networks without requiring authentication. OWE uses an enhanced version of the 4-way handshake to establish a pairwise key between the client and the AP, which is then used to encrypt the wireless traffic using WPA2 or WPA3 protocols. OWE can be used for visitor networks where encryption is needed but authentication is not required.

Wi-Fi 6 is an industry certification for products that support the new wireless standard 802.11ax, also known as "high-efficiency wireless". Wi-Fi 6 offers increased capacities, improved resource utilization and higher throughput speeds than previous standards.

Option B: ClientMatch
This is because option B shows how to use ClientMatch to optimize the wireless performance of Wi-Fi 6 clients on a UniFi network. ClientMatch is a feature that uses machine learning to analyze the traffic patterns of each client and assign them to the best available AP based on their location, device type, and network conditions 2. Therefore,
option B is the best technology to implement for your customer's issue.

The correct answer is B. An event log message is created. The do-not-disable parameter is used to prevent the switch from disabling the port when a loop is detected by the loop-protect feature. Instead, the switch will generate an event log message that indicates the port number and the VLAN ID where the loop was detected. The switch will also send a trap to the SNMP manager, if configured 1.
The other options are incorrect because:
A. Port status will not be validated once status is cleared. The port will remain enabled even if a loop is
detected, unless the loop-protect action is changed to tx-disable or tx-rx-disable 1.
C. The network analytics engine will not be triggered by a loop detection. The network analytics engine is a
feature that allows users to monitor and troubleshoot network issues using scripts and agents 2.
D. Port status LED will not blink in amber with 100Hz. The port status LED will indicate the normal port
status, such as link speed and activity, regardless of the loop detection 3.

The reason is that PBR allows you to route packets based on policies that match certain criteria, such as source or destination IP addresses, ports, protocols, etc. PBR can also be used to set metrics, next-hop addresses, or tag traffic for different routes.

A session-based ACL is applied to traffic entering or leaving a port or VLAN based on the direction of the session initiation. To allow ping from any wired station to wireless clients but not vice versa, a session-based ACL should be used to deny icmp echo traffic from any source to any destination, and then permit icmp echo-reply traffic from any source to user destination. The user role represents wireless clients in
AOS 10.

Loop protection is a feature that detects and prevents loops in layer 2 networks. Loop protection can be enabled on ports, LAGs, or VLANs. When loop protection is enabled, the switch sends periodic loop protection messages on the interface and expects to receive them back. If a loop protection message is received back on the same interface, it indicates a loop and the switch takes an action to disable the interface or block traffic on it3. The loop-protect re-enable-timer command is used to configure the length of time the switch waits before re-enabling an interface that was disabled due to loop detection. The default value is 0, which means that the interface remains disabled until manually re-enabled 3. To automate the process of resuming the port operational state once a loop on a client port is cleared, the loop-protect re-enable-timer command can be used with a non-zero value on the interface range that includes the client ports 3. Therefore, answer C is correct.

According to the Aruba Documentation Portal1, the Aruba 6300 CX switches support various features to control the PoE devices on specific ports, such as device profiles and classifier policies. These features can help reduce the power consumption and improve the performance of the PoE devices.

802.11k is the correct answer because it defines radio resource measurement mechanisms that help clients learn more about the surrounding RF environment, including neighbor-related information. This can improve roaming efficiency by giving the client more useful data when selecting a candidate AP. 802.11r is focused on fast transition keying and reduced reauthentication delay. 802.11w protects management frames, and 802.3at is a PoE standard unrelated to WLAN roaming intelligence.

BSS coloring is a mechanism that helps identify the BSS Basic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. on the same channel and differentiate them from other BSS on the same channel 12. Each BSS is assigned a color code, which is a 6-bit value that is carried in the PHY header of the Wi-Fi frames 12. By using BSS coloring, the APs and clients can reduce the threshold for interference detection and avoid unnecessary backoff or retransmissions when they detect frames from other BSS with different colors 12. This can improve the spectral efficiency and throughput of the network 12. The other options are incorrect because they do not describe the primary benefit of BSS coloring.
