In the United States, the operation in the 6GHz band for Wi-Fi devices such as the AP-634 and AP-635 is regulated by the Automated Frequency Coordination (AFC) system, which determines the channels that can be used based on the location. Since the Proof of Concept (POC) was conducted in a different location using AP-635 APs, the allowable channels identified by the AFC service for that location would be different than the channels allowed for the actual deployment location of the AP-634 APs. This would result in a different set of broadcasting channels being available for use in the new warehouse deployment.

In VRRP (Virtual Router Redundancy Protocol), only one switch should be the primary (master) for a given virtual IP address, with the other switches being backups. If both switches are showing as active, it suggests a misconfiguration where both are set to act as the primary for the same VRRP group. The exhibits provided indicate that both switches believe they are the active or primary for the VRRP group, which is an incorrect configuration.

The configuration shown in the third exhibit details a client role mapping that associates different client profile tags with specific client roles. When a new device, such as an Android phone, connects to the network, it will be profiled and assigned a role based on the mappings defined. If the device does not match any predefined profiles, it would be assigned the "unmatched-device" role. This is under the assumption that default settings are in place and the client does not match the criteria for any of the specific roles like "byod", "iot-internet", or "iot-local". Therefore, an Android phone connecting for the first time and not matching any specific profile tag would be assigned to the "unmatched-device" role.

When cluster preemption is not enabled, access points (APs) will not automatically fail back to the primary gateway cluster once it is up again after having failed over to the secondary. This would result in an equal split of APs across primary and secondary clusters if both clusters are operational. Without preemption, there's no automatic rebalancing of APs back to the primary cluster, leading to the current distribution.

The sequence to return to the previous firmware version after an unsuccessful update would typically be:

• hit any key to stop autoboot(This would prevent the system from automatically booting into the current, problematic firmware.)
• def_part 1(This command sets the default boot partition, which is likely where the previous working firmware is located.)
• bootf(This command would boot from the specified flash partition, which after the second step, would be the previous firmware.)
• osinfo(After the system is booted, this command could be used to confirm the firmware version now running on the gateway.)

The event log showing PMK (Pairwise Master Key) and OKC (Opportunistic Key Caching) key add/update and delete operations is indicative of normal client behavior in a WLAN environment. These events are part of the standard process for maintaining client session security and do not necessarily indicate any issue.

It is a common practice to separate successful and failed test results into different files for ease of troubleshooting. If the "datagrams.pcap" file shows no issues, it's likely because it only contains successful test data, and the failed tests that could explain the poor user experience would be in a different file, such as "datagrams-failed.pcap."

The CLI output provided shows routing information from a CX 6300 switch. The output under "VRF: default" shows various IP routes, including a route for 10.203.1.100/32 with a next hop of 172.21.11.2. This indicates that the route to the client with IP address 10.203.1.100 is known in the network and is reachable via another device in the fabric, which has the loopback IP address 172.21.11.2. Since the route is present in the routing table, it means that the client is known and active within the fabric network.

When onboarding devices into a centralized management system, each device can have its individual admin password set during the onboarding process. If this password doesn't match what is expected at the group level in the central management platform, login issues such as the one described can occur.

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.

In OSPF, when a router learns about an external network through both E1 and E2 advertisements, and if both have the same path cost, the router will prefer the E1 path. This is because E1 routes consider both the external cost to reach the external network and the internal cost to reach the ASBR, providing a more comprehensive metric. E2 routes only consider the external cost and ignore the internal cost to the ASBR, which could potentially lead to suboptimal routing. Therefore, the router will choose the E1 path due to its more accurate representation of the total path cost.

In an Aruba network, if an SSID is configured for a primary and secondary gateway cluster with cluster preemption enabled, each AP individually will decide to move to the secondary gateway cluster if all of the nodes in the primary gateway cluster are down. This decentralized decision-making process enhances network resilience and ensures uninterrupted service for clients connected to the APs.

The Change of Authorization (CoA) messages are used in network access control scenarios and are typically received by the network access server, in this case, an Aruba AOS 10 Gateway. The correct command to verify the receipt of a CoA message is related to the control path traffic because CoA is a control plane function.

Option B,packet-capture controlpath udp 3799, is the correct answer because it specifies capturing control plane traffic on UDP port 3799, which is the standard port for CoA messages.

Options A, C, and D are incorrect because:

• Option A captures data plane traffic, not control plane traffic.
• Option C'spacket-capture interprocess udp 3799does not refer to a standard command for capturing CoA messages.
• Option D,tcpdump host-port 3799, does not specify the correct syntax for capturing traffic on Aruba devices.

When troubleshooting a WLAN with 802.1X tunneled SSID issues, AP tunnel states indicate the status of the connection between the AP and the gateway/controller. The states 'SM_STATE_REKEYING' and 'SM_STATE_CONNECTING' could indicate transitional states where the connection has not been fully established, hence users might face issues connecting to the SSID. 'SM_STATE_REKEYING' implies that the AP is in the process of re-establishing encryption keys, while 'SM_STATE_CONNECTING' indicates that the AP is trying to establish a connection with the controller or gateway. These states could lead to temporary connectivity issues until the state transitions to 'SM_STATE_CONNECTED'.

The issue indicated by the output is an invalid pre-shared key (PSK). The logs show multiple failures during the WPA2 key exchange process, which points to a mismatch between the PSK configured on the client device and the PSK expected by the AOS 10 mobility gateway.

To achieve the bandwidth limits set by the network administrator, both per-application and total limits need to be configured. Option B shows the configuration for setting a per-application bandwidth limit, which can restrict YouTube traffic to 10 Mbps in both directions. Option D shows the configuration for setting a total bandwidth limit for all users within the voice role to 50000 Kbps (or 50 Mbps), satisfying the requirement to restrict total wireless bandwidth. By applying these configurations in HPE Aruba Networking Central, the administrator will successfully implement the necessary controls to ensure that visitor traffic does not impede the network performance for employee traffic, aligning with the capabilities of Aruba solutions to manage and prioritize network resources effectively.

In a high availability setup where both primary and secondary gateway clusters are present, APs are typically designed to connect to the primary cluster. If the APs are equally split between the primary and secondary, this may indicate that some APs cannot reach the primary cluster due to connectivity issues or reachability constraints, thus falling back to the secondary cluster.

Based on the criteria provided for wireless guest users, the correct user role configuration must allow internet access, only allow access to public DNS servers, deny access to all internal networks except for any DHCP server, and place the Wi-Fi guests on VLAN 555. The ACLs must permit services necessary for basic internet access (such as DNS and DHCP) and block access to internal networks.

Option A satisfies these criteria with the following configurations:

• user-role "WiFi-guest": This defines the role for Wi-Fi guests.
• access-list session dhcp-acl: This applies the access list that likely permits DHCP, which is necessary for guests to obtain an IP address.
• access-list session dns-acl: This applies the DNS access list, which likely restricts guests to using public DNS servers.
• access-list session internal-networks: This applies the internal networks access list, which denies access to internal networks.
• vlan 555: This sets the VLAN for Wi-Fi guests to 555.

Options B, C, and D are incorrect because they includeaccess-list session allowallwhich would permit all traffic, contradicting the requirement to deny access to all internal networks.

The Modulation and Coding Scheme (MCS) used by wireless stations is directly affected by the signal-to-noise ratio (SNR) and the frequency band. Higher SNR can lead to higher MCS values, which means better data rates. The frequency band can affect MCS due to different channel characteristics, such as the presence of interference and propagation properties, which are factors in determining data rates.

Multi-Pre-Shared Key (MPSK) with ClearPass is the recommended solution for a scenario where the IT Helpdesk needs to configure IoT devices to connect to a single SSID using unique PSKs. MPSK allows for the use of different PSKs on the same SSID, and ClearPass enables the management of these unique keys efficiently.

When configuring Virtual Switching Extension (VSX) in a campus topology for link aggregation across two aggregation switches, it is important to synchronize Multi-Chassis Link Aggregation Group (MC-LAG) interfaces. The command "vsx-sync mclag-interfaces" ensures that the state and configuration of MC-LAG interfaces are synchronized between the two VSX-linked switches,providing consistent link aggregation and preventing any loops or mismatched configurations that might occur if the interfaces were not in sync.
