The Aruba CX 6400 switch is a modular switch that supports high-performance and high-density Ethernet switching for campus and data center networks. One of the features that distinguishes the Aruba CX 6400 switch from most typical campus switches is virtual output queueing (VOQ).  VOQ is a technique that implements large ingress packet buffers on each port to prevent head-of-line blocking and packet loss due to congestion 2 .  VOQ allows each port to have multiple queues for different output ports and prioritize packets based on their destination and QoS class 2 .  VOQ enables the Aruba CX 6400 switch to achieve high throughput and low latency for various traffic types and scenarios.

HPE Aruba Networking Central performs rogue AP detection, classification, and containment through RAPIDS (Rogue Access Point Intrusion Detection System) . In the Classic Central interface, detected wireless devices are managed under Security > RAPIDS > Rogues . RAPIDS categorizes detected APs as Rogue, Suspected Rogue, Interfering, Neighbor, Manually Contained, or other applicable states. Aruba Networking

For manual reclassification, the administrator selects the detected AP, chooses Reclassify , and then selects the desired classification. Aruba documentation explicitly lists Rogue, Neighbor, and Manually contained among the available manual classifications. A Manually contained classification enables rogue containment against the selected AP, subject to the required containment configuration being enabled. Aruba Networking

Therefore, Security > RAPIDS is the appropriate location for this task. Applications > IDS/IPS is not the workflow used to reclassify detected APs. Devices > Access Points primarily manages authorized infrastructure APs rather than RAPIDS classifications. Audit Trail records administrative and system activities; it is not the rogue-device classification interface.

Study Guide Topics: Aruba Central Security, RAPIDS, WIDS/WIPS, Rogue AP Classification, Manual Containment, Neighbor APs.

According to the Aruba Documentation Portal 1 , the firewall role derivation flow in the correct order is:

Server derived role

User derived role

Authentication default role

Initiation role assigned

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 it 3 . 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.

On an AOS-CX switch , REST API authentication uses the HTTP POST method against the login resource. Aruba specifies that a REST API session is initiated by sending the username and password through a POST request. After successful authentication, the switch returns session information that is used for subsequent API requests. Aruba Networking

For changing the administrator password, Aruba documents the use of PUT against the user resource, for example PUT /rest/v10.xx/system/users/admin, with the new password included in the request data. Therefore, D correctly associates POST with login and PUT with changing the management password . Aruba Networking

Option A is incorrect because AOS-CX does not provide comprehensive semantic validation for REST writes. Aruba explicitly warns that configuration errors written directly to the database can destabilize the switch. Aruba Networking

Option B is also incorrect. Read-only mode blocks writes to most resources, but exceptions exist. POST is still permitted for functions such as login , and certain PUT/POST operations remain available. Aruba Networking Option C simply reverses the correct HTTP methods.

Study Guide Topics: AOS-CX REST API, REST Authentication, HTTP POST/PUT Methods, API Access Modes, Read-Write versus Read-Only Access.

VXLAN is a technology that can be used to meet the requirement of using a legacy application that communicates at layer-2 across a layer-3 network. Static VXLAN is a feature that allows the creation of layer-2 overlay networks over a layer-3 underlay network using VXLAN tunnels. Static VXLAN does not require any control plane protocol or VTEP discovery mechanism, and can be configured manually on the Aruba CX 6200 switches. The other options are incorrect because they either do not support layer-2 communication over layer-3 network or are not supported by Aruba CX 6200 switches.

The show aaa authentication port-access interface all client-status command displays the status of all clients authenticated by port-based access control on all interfaces. The output includes the MAC address, user role, VLAN ID, and session timeout for each client. This command can be used to examine information on which role the guest user has been assigned by the AOS-CX switch.
