The correct Bandwidth Control settings for 1024 Kbps down and 2048 Kbps up for the SSID are shown in Option D. In Option D, the downstream is set at 1024 Kbps and the upstream at 2048 Kbps, both configured per user, which matches the requested configuration. This setup ensures that each user has a guaranteed bandwidth allocation of the specified rates when connected to the SSID, providing a controlled and predictable user experience.

The command shown in the exhibit is:

Access-1# show ubt state

This command displays the User-Based Tunneling (UBT) status on an Aruba CX switch. UBT allows wired access devices (like CX 6300/6400) to extend tunneled connectivity to Aruba gateways, using GRE tunnels for user traffic.

The output contains the following sections:

1. Local Conductor Server (LCS) State

Primary : 172.16.200.252 ready_for_bootstrap operational_primary

Secondary : 172.16.200.253 ready_for_bootstrap operational_secondary

This confirms that two gateways (IP 172.16.200.252 and 172.16.200.253) form an LCS pair in an Aruba gateway cluster.

Exact extract:

“The Local Conductor Servers (LCS) represent the pair of Aruba Gateways that control and terminate UBT tunnels. One operates as the primary (active) and the other as the secondary (standby). These gateways must be configured as a cluster pair.”

2. Switch Anchor Controller (SAC) State

Active : 172.16.200.252 20:4c:03:81:e7:ca registered

Standby : 172.16.200.253 20:4c:03:b2:12:0a registered

Both gateways are registered as active and standby switch anchor controllers. This is a clear indication that the switch (Access-1) has successfully established tunnels to both gateways within the cluster.

Exact extract:

“The Switch Anchor Controller (SAC) section lists both cluster members to which the switch forms GRE tunnels. The switch maintains active and standby tunnels for redundancy.”

3. User Anchor Controller (UAC) State

Each connected user is mapped to a User Anchor Controller (UAC) — one of the two gateways — depending on cluster load balancing:

User Anchor Controller (UAC): 172.16.200.252

User Anchor Controller (UAC): 172.16.200.253

Each user session is anchored on a specific gateway within the cluster. The presence of two different UAC IPs confirms that users are being distributed across both gateways — a behavior that occurs only in a clustered gateway configuration.

Exact extract:

“In a clustered gateway deployment, each user session is dynamically anchored to one of the gateways. The UAC field shows which gateway currently handles each user session.”

Conclusion:

From the output:

Two gateways are shown as primary and secondary LCS.

Both are registered as SACs (tunnel endpoints).

Users are distributed across both gateways as UACs.

This confirms that Access-1 (the CX switch) has established GRE tunnels to a pair of gateways within a cluster.

Hence, the correct answer is A. A pair of gateways within a cluster.

Why the Other Options Are Incorrect:

B. A pair of switches running VXLAN:UBT tunnels are GRE-based and terminate on Aruba Gateways, not VXLAN-enabled switches.

“User-Based Tunneling uses GRE tunnels to Aruba Gateways; VXLAN is not used for UBT.”

C. A single gateway within a cluster:The output explicitly shows two controllers (active and standby) registered — not a single one.

D. A pair of standalone gateways:The LCS state shows primary/secondary operational roles, which exist only in a cluster, not standalone gateways.

In the context of an EVPN VXLAN fabric, the Route-Reflector Persona is most appropriately configured at the Services Aggregation layer. This layer is responsible for interconnecting different network services and typically includes more robust, higher-capacity devices capable of handling the route-reflection functions for EVPN VXLAN.

In an Aruba Networks fabric, route reflectors are used to optimize the distribution of BGP routes. The Services Aggregation layer, which is centrally located in the network topology, is best suited for this role due to its high availability and ability to efficiently manage routes between the core and access layers.

Therefore, if you were to click on the image provided, you would select the Services Aggregation layer to configure the Route-Reflector Persona.

Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:

When configuring an 802.1X supplicant in Microsoft Windows for EAP-PEAP (Protected EAP) using EAP-MSCHAPv2, both user and machine credentials can be used for authentication. The network administrator has already enabled user and machine authentication under Additional Settings, but to meet the stated requirements (AES encryption and server certificate validation), two critical steps remain:

Enable server certificate validationThis ensures the client validates the identity of the RADIUS server (such as Aruba ClearPass or another authentication server) to prevent man-in-the-middle attacks. It satisfies the requirement for “validation of server certificate in Windows 10”.

Exact Extract:

“For EAP-PEAP with EAP-MSCHAPv2, select ‘Validate server certificate’ to ensure the client trusts the authentication server’s identity. The server certificate must be signed by a CA trusted by the client.”

Enable user authenticationWhile both user and machine authentication are possible, user authentication must be explicitly enabled so that credentials (domain or local user) are sent after machine authentication completes. This enables the full EAP-MSCHAPv2-based user and machine authentication process.

Exact Extract:

“In EAP-PEAP properties, ensure ‘Enable user authentication’ is selected to authenticate both the workstation and logged-on user credentials when using EAP-MSCHAPv2.”

Additionally, Windows 10 uses AES encryption automatically when WPA2/WPA3-Enterprise is configured, fulfilling requirement (1). RC4 encryption is not applicable because AES is the default cipher for WPA2 Enterprise networks.

Why the Other Options Are Incorrect:

C. EAP-TLS-based user and machine authentication:The question specifies EAP-MSCHAPv2, not EAP-TLS. EAP-TLS uses digital certificates for mutual authentication, while PEAP with EAP-MSCHAPv2 uses username and password-based credentials.

“EAP-TLS is certificate-based; PEAP-MSCHAPv2 uses password-based authentication.”

D. Change default RC4 encryption for AES:RC4 is used in older WPA or TKIP security types. When using WPA2-Enterprise, AES is automatically selected and cannot be manually overridden.

“WPA2-Enterprise (802.1X) uses AES-CCMP encryption; RC4/TKIP is not applicable to modern configurations.”

The packet decode excerpt shows a QoS Data frame, not a multicast-control low-rate frame.

Frame control flags indicate:

Subtype: QoS Data → This is unicast, not broadcast/multicast

From DS bit = 1, To DS bit = 0 → Wireless unicast from AP to client

High-rate MCS data present → Indicates optimized transmission speed

This behavior aligns directly with Dynamic Multicast Optimization (DMO).

Aruba DMO Overview — Official Behavior

ArubaOS Wi-Fi optimization guides state:

“Dynamic Multicast Optimization converts multicast packets into unicast transmissions and sends them using the highest supported data rate, improving delivery reliability and efficiency.”

This means:

Before DMO

After DMO

Multicast sent at lowest basic rate (e.g., 6 Mbps)

Converted to unicast → can use high PHY rates (e.g., 300 Mbps+)

High drop probability

Reliable delivery

Poor performance

Optimized throughput

The packet remaining a Data/QoS Data subtype is correct — DMO does not change the 802.11 frame Type field; it changes transmission handling and rate control.

Why the Other Options Are Incorrect

Option

Why Incorrect

A BCMCO does not exist — incorrect feature name

B Type consistency is not the key validation point — rate increase is

D Packet length always appears in frame decode; optimization never hides it

✅ Final Verified Answer: C

The data rate increased from 6 Mbps to 300 Mbps because Dynamic Multicast Optimization (DMO) was configured.

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 the context of ArubaOS-CX, particularly with the 6300 series switches, setting the MTU on a routed Link Aggregation Group (LAG) interface requires the interface lag id command in the configuration, specifying the LAG interface you're configuring. The ip mtu command is then used to set the desired MTU size for that LAG. Option A correctly shows this configuration process, where the MTU is set to 9198 for the LAG interface, in line with the requirements for routing larger frames, which could be necessary for certain applications or data flows that require jumbo frames.

The information related to the configuration of Aruba switches is consistent with the principles and guidelines found in the technical documentation for the ArubaOS-CX 6300 series switches, which emphasizes the importance of correct MTU settings for network performance and stability.

The command output shows WMM transmit counters per access category on the AP:

Tx WMM [BK] 56

Tx WMM [BE] 35

Tx WMM [VI] 200093

Tx WMM [VO] 0

Drops: BE Dropped 566, VO Dropped 3

In Aruba WLAN QoS, traffic is queued using WMM access categories mapped from 802.1p/DSCP/UP values:

AC_VO (Voice) is for latency-sensitive voice; it should carry EF/DSCP 46 and UP 6.

AC_VI (Video) is for video; it should not carry voice traffic.

The statistics show zero traffic in AC_VO and a very large amount in AC_VI during the test calls. This indicates that voice frames are being mapped to the Video access category instead of Voice, which reduces priority and increases contention—consistent with poor call quality during busy periods.

HPE Aruba documentation states:

“Voice traffic (EF/46, UP 6) must be mapped to WMM Voice (AC_VO) to receive the highest priority.”

“Incorrect DSCP/UP-to-WMM mapping results in voice frames using lower-priority queues (e.g., AC_VI) and degraded call quality.”

Therefore, the corrective action is to reconfigure DSCP/UP-to-WMM mapping so that DSCP 46 (EF) maps to UP 6 → AC_VO on the SSID/user-role, ensuring voice traffic uses the proper Voice queue.

Why others are incorrect:

B. enable WMM for the SSID – WMM is already active (WMM counters are present).

C. disable AirSlice – Not indicated; issue is misclassification, not airtime reservation.

D. update ACLs – ACLs don’t fix QoS category mapping for voice marking.

In BGP, the route marked with a ">" symbol is the best route that is chosen based on BGP attributes in the following order: highest weight (Cisco-specific), highest local preference, originated by BGP running on the local router, shortest AS path, lowest origin type, lowest MED, eBGP over iBGP, closest IGP neighbor, and lowest BGP router ID. Based on the table provided, Option E would be marked with a ">" symbol as it has the highest local preference of 100 which is a decisive factor in the BGP best path selection process.
