• Question 41:

  A customer has deployed an AOS 10 mobility gateway cluster consisting of three controllers at a single site The WLAN is configured to tunnel wireless device traffic to the AOS 10 mobility cluster The clients are authenticated by ClearPass using WPA3-Enterprise (opmode wpa3-aes-ccm-128). The security team has requested the ability to force a wireless device to reauthenticate using ClearPass.

  Which steps are required to ensure ClearPass can consistently initiate a change of authorization against an AOS 10 mobility cluster, including during gateway failover scenarios? (Select two)

  A. set cluster mode to Auto Site under High Availability - Cluster configuration
  B. modify WLAN - SSID - VLAN - Mode Configuration
  C. enable manual cluster configuration under High Availability - Cluster Configuration
  D. enable Dynamic Authorization CoA under High Availability - Cluster Configuration
  E. modify NAS IPv4 address under Security - Advanced - RADIUS Client
  D. enable Dynamic Authorization CoA under High Availability - Cluster Configuration
  E. modify NAS IPv4 address under Security - Advanced - RADIUS Client

  ---

  Explanation/Reference:

  To ensure that ClearPass can initiate a Change of Authorization (CoA) consistently, it's important to enable dynamic authorization to allow RADIUS CoA messages to be processed. This setting typically falls under the high-availability cluster configuration to ensure that it persists across gateway failovers. Additionally, the NAS IP address must be configured under RADIUS client settings to ensure that the correct IP address is used for RADIUS communications, which is necessary for CoA to function correctly.

• Question 42:

  Which data transmission method provides the most efficient use of airtime for VoIP traffic?

  A. FDMA
  B. OFDM
  C. MU-MIMO
  D. TWT
  C. MU-MIMO

  ---

  Explanation/Reference:

  MU-MIMO (Multi-User, Multiple Input, Multiple Output) provides the most efficient use of airtime for VoIP traffic among the options listed. MU-MIMO allows multiple users to receive multiple data streams simultaneously, improving the overall efficiency of the network, especially in dense environments where VoIP applications need consistent and reliable connectivity.

• Question 43:

  A customer would like to allow their IT Helpdesk to configure loT devices to connect lo a single SSID using a unique PSK that other devices cannot use. Which solution would you recommend?

  A. MPSK AES with MAC Auth
  B. MPSK Local
  C. MPSK AES with Cloud Auth
  D. MPSK AES with ClearPass
  D. MPSK AES with ClearPass

  ---

  Explanation/Reference:

  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.

• Question 44:

  A network technician racked up two 9240 mobility gateways in a single cluster that will be terminating 1700 APs in a medium-sized branch office Next, the technician cabled the gateways with two SFP28 Direct Attach Copper (DAC) cables, distributed between a two-member core switching stack and powered them up.

  What must the network administrator do next regarding the gateway configuration to ensure maximum wired bandwidth utilization?

  A. Map two physical ports to a port channel on each gateway.
  B. Make an ports trunk interfaces and permit data VLANs
  C. Disable the spanning tree and allocate unique VLANs to each port.
  D. Manually set 25Gbps speeds on all ports.
  A. Map two physical ports to a port channel on each gateway.

  ---

  Explanation/Reference:

  To maximize wired bandwidth utilization, especially when multiple APs are terminating on mobility gateways, it's best practice to aggregate physical ports into a port channel. This provides redundancy and increased bandwidth by combining the throughput of multiple ports.

• Question 45:

  A customer wan a gateway connected to a device on gigabitethernet0/0/3 configures an Asset ID TLVon the device for inventory management. Exhibit.

  

  The customer mentions me Asset ID is not shown What is causing the issue?

  A. LLDP TX is not enabled.
  B. LLPD-MED needs to be enabled.
  C. MTU size is too small.
  D. Unknown TLVs cannot be displayed.
  D. Unknown TLVs cannot be displayed.

  ---

  Explanation/Reference:

  The issue is that unknown TLVs (Type Length Values) cannot be displayed. LLDP (Link Layer Discovery Protocol) is used to share device information with network neighbors, but if a TLV is not recognized by the LLDP implementation on the gateway, it won't be displayed or processed. Hence, the Asset ID TLV set on the device for inventory management is not showing up because it is unrecognized or unsupported by the gateway's LLDP.

• Question 46:

  Which command would allow you to verity receipt of a CoA message on an AOS 10 GW?

  A. packet-capture datapath udp 3799
  B. packet-capture controipath udp 3799
  C. packet-capture interprocess udp 3799
  D. tcpdump host-port 3799
  B. packet-capture controipath udp 3799

  ---

  Explanation/Reference:

  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's packet-capture interprocess udp 3799 does 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.

• Question 47:

  Refer to the exhibit.

  

  Which statement is true?

  A. The client performed passive scanning
  B. The client is using BSS Fast Transition
  C. The client is failing 802.1X authentication
  D. The client used an incorrect passphrase
  C. The client is failing 802.1X authentication

  ---

  Explanation/Reference:

  The exhibit shows a series of 802.1X authentication steps with multiple "Deauthentication" frames, which indicate that the client is not successfully completing the authentication process. Since the frames show repeated attempts at authentication followed by deauthentication, this suggests that the client is failing the 802.1X authentication process, which is required for network access in a WPA2/WPA3-Enterprise security environment.

• Question 48:

  A customer's infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile cased on best practices. Why do they have an equal split of their 120 APs across the primary and secondary gateway clusters?

  A. The primary gateway cluster is a heterogeneous cluster with six nodes.
  B. The primary and secondary gateway clusters are up. and the cluster preemption is enabled
  C. The secondary gateway cluster is a homogeneous cluster with six nodes.
  D. The primary and secondary gateway clusters are up. but the cluster preemption Is not enabled
  D. The primary and secondary gateway clusters are up. but the cluster preemption Is not enabled

  ---

  Explanation/Reference:

  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.

• Question 49:

  A customer's infrastructure is set up to use Doth primary and secondary gateway clusters on the SSID profile What is a valid reason for the AP to failover to the secondary gateway cluster?

  A. The primary gateway cluster is up. out the AP is unable to reach the primary gateway cluster.
  B. The secondary gateway cluster is up. hut the AP is unable to reach the secondary gateway cluster
  C. The secondary gateway cluster is heterogeneous.
  D. The secondary gateway cluster is homogeneous.
  A. The primary gateway cluster is up. out the AP is unable to reach the primary gateway cluster.

  ---

  Explanation/Reference:

  In Aruba's infrastructure, the Access Points (APs) are configured with primary and secondary gateway clusters to ensure connectivity and resiliency. The APs will failover to the secondary gateway cluster if they are unable to reach the primary gateway cluster, even if the primary cluster is operational. This mechanism ensures that the APs maintain connectivity to the network infrastructure for continuous service delivery.
