The correct answer is D. Dynamic Segmentation. HPE Aruba Networking describes Dynamic Segmentation as an identity-based access control solution for Zero Trust and SASE security from edge to cloud. Dynamic Segmentation applies policy based on the identity and role of users and devices, rather than relying only on physical network location, VLAN placement, or static port configuration. This is important in Zero Trust because no user, device, or network segment should be automatically trusted. Access should be continuously controlled and limited to only the resources required. HPE Aruba Networking documentation also explains that Dynamic Segmentation establishes least-privilege access by segmenting traffic based on identity and associating consistent role-based access policies across wired, wireless, and WAN networks. The other options are not the best answer. Virtual Switching Framework and Virtual Switching Extension are resiliency or virtualization technologies, not the core Zero Trust/SASE policy feature. Network Analytics Engine is useful for monitoring, automation, and troubleshooting, but Dynamic Segmentation is the security framework feature directly tied to Zero Trust and SASE.

The correct answer is B. Connect the USB Bluetooth adapter to the switch’s USB-A port. HPE Aruba Networking CX 8100 installation documentation states that the Aruba CX mobile app and Aruba USB Bluetooth adapter enable switch configuration from a mobile device. It also identifies the CX 8100 front-panel USB-A auxiliary port as the port used for file management, switch software downloads, or Aruba accessories. Therefore, for an Android mobile setup workflow using the Aruba CX mobile app, the USB Bluetooth adapter connects to the switch’s USB-A auxiliary port. The USB-C port on the CX 8100 is a serial console port, not the port for the USB Bluetooth adapter. Connecting the Android phone directly to the USB-C console port is not the Bluetooth mobile-app method. Connecting the phone to the management port with an RJ-45 adapter is also not the recommended mobile-app setup method. The supported mobile method is the Aruba CX mobile app through the USB Bluetooth adapter.

The correct answer is C. Input errors have occurred. The interface output shows CRC/FCS errors with a value of 1254 under the RX column. CRC/FCS errors are receive-side frame check errors, so they indicate that the switch has received corrupted frames on this interface. HPE Aruba Networking AOS-CX show interface documentation lists interface statistics including packets, bytes, dropped frames, pause frames, errors, CRC/FCS, collisions, runts, and giants, which confirms that CRC/FCS is part of the interface error statistics. Option A is incorrect because the output says VLAN Mode: access and Access VLAN: 90; an access VLAN is untagged toward the endpoint, not an 802.1Q tagged trunk VLAN. Option B is incorrect because the MTU is shown as 1500, and the Jumbos counter is 0, so the output does not indicate jumbo-frame use. Option D is incorrect because the shown output does not state that PoE is disabled. The key troubleshooting clue is the nonzero receive CRC/FCS counter. ( arubanetworking.hpe.com )

The correct answer is B. The switch does not have enough PoE budget per port. The HPE Aruba Networking 580EX Series access point requires appropriate power to boot and illuminate its LEDs. HPE Aruba Networking documentation states that the 580EX Series supports 802.3bt Class 6 power or AC power. A standard HPE Aruba Networking CX 6000 48G 4SFP switch, such as the R8N86A model, is a non-PoE switch; the PoE-capable version is identified separately as the CX 6000 48G Class 4 PoE 4SFP 740W switch. Even when using a PoE-capable CX 6000 model, Class 4 PoE provides up to 30W per port, while the AP requires 802.3bt Class 6 or AC power for normal operation. Therefore, if the AP has no lights, the most likely cause from the options is insufficient or unavailable PoE power from the switch port. A wrong VLAN, missing STP configuration, or failure to connect to HPE Aruba Networking Central would not normally prevent the AP from receiving power and showing LEDs.

The correct answer is B. PoE is disabled on the interface. If there are no lights on the access point, the first issue to investigate is whether the AP is receiving power. HPE Aruba Networking 550 Series installation documentation identifies Power over Ethernet as a supported power source for the AP, including IEEE 802.3bt or 802.3at PoE. HPE Aruba Networking AOS-CX documentation for the CX 6000/6100 PoE command shows that per-interface power distribution can be enabled with power-over-ethernet and disabled with no power-over-ethernet. If PoE is disabled on the switch interface, the AP will not receive power from the Ethernet cable and therefore may show no LEDs. Option A is incorrect because a missing STP configuration would not prevent the AP from powering on. Option C is incorrect because failure to reach HPE Aruba Networking Central would occur after the AP is powered and network-connected. Option D is also incorrect because a wrong VLAN can prevent management or provisioning, but it would not normally stop the AP LEDs from turning on.

The correct answer is D. Create VSF on the CX 6200 switches and a LAG between the CX 6200 and 2530 switches. HPE Aruba Networking documentation explains that VSF allows multiple individual switches to operate as a single logical device using standard Ethernet links. The CX 6200 supports VSF stacking, so two CX 6200 aggregation switches can be combined into a single logical aggregation switch. HPE Aruba Networking Layer 2 documentation also describes link aggregation as grouping individual physical interfaces into a single logical link, increasing bandwidth and providing resiliency when links fail. In this design, the 2530 access switch can use two uplink ports in a trunk/LAG toward the aggregation layer, while the CX 6200 side operates as one logical switch because of VSF. Option A is incorrect because a CX 6200 and a 2530 cannot be placed into one common VSF stack. Option B is incorrect for the same reason: the 2530 is not stacked with the CX 6200. Option C is incomplete because a LAG from one access switch to two separate aggregation switches requires the aggregation side to act as one logical switch, which is provided by VSF in option D.

The correct answer is D. A DHCP server must be configured with the required options. HPE Aruba Networking AOS-CX documentation explains that ZTP is used to automatically load a switch configuration from a server when the switch boots from a factory-default configuration. The AOS-CX Fundamentals Guide for the 4100i, 6000, and 6100 switch series states that ZTP supports DHCP standards and DHCP options, and that support is limited to the listed DHCP options for ZTP on AOS-CX. The same guide describes setting up ZTP on a trusted network by preparing the configuration, setting up a TFTP server, and configuring DHCP-related information. Option B is incorrect because the guide references TFTP, not SFTP, for the ZTP server workflow. Option C is incorrect because the listed process does not use SCP for the initial template download. Option A is misleading because ZTP is enabled only when the switch is in factory-default configuration; the key requirement is the DHCP-based provisioning environment with the proper options.

The correct answer is A. Configure an SVI for each VLAN. Hosts in different VLANs are in different Layer 2 broadcast domains, so they cannot communicate directly through normal switching alone. To enable communication between VLANs, the switch must provide Layer 3 gateway interfaces for those VLANs. On HPE Aruba Networking CX switches, this is done with switched virtual interfaces, or SVIs, using interface vlan < VLAN-ID > and assigning an IP address to each VLAN interface. HPE Aruba Networking documentation shows Layer 3 VLAN interfaces using interface vlan with an IP address, and also refers to an SVI as the Layer 2 VLAN interface IP address used by the switch. Option B is not the best answer because simply enabling IP forwarding does not create gateway interfaces for the VLANs. Option C is incorrect because trunking VLANs to another Layer 2 switch only extends VLANs; it does not route between them. Option D is incorrect because VLANs separate Layer 2 domains, and inter-VLAN communication requires routing, not bridging.

The correct answer is D. If the ZTP operation detects that the switch configuration is different from the factory-default configuration, the ZTP operation ends. HPE Aruba Networking AOS-CX documentation explains that the ZTP process starts when the switch boots with the factory-default configuration. During the ZTP process, if the switch detects that its configuration is different from the factory-default configuration, the ZTP operation ends and the switch must be configured at the installation site. This directly addresses the customer’s concern: ZTP is intended for new or factory-default switches, and it should not overwrite or change switches that have already been manually configured or deployed. Option A is incorrect because the end condition is not based on a TFTP server detecting a serial-number configuration file. Option B is incorrect because being added to Central is not the stated stopping condition. Option C describes force provisioning, which can intentionally start provisioning behavior, but it does not address the concern about protecting already configured switches.

The correct answer is D. 3311. HPE Aruba Networking AOS-CX documentation identifies valid VLAN IDs as being in the range of 1 to 4094 for VLAN-related configuration, including access VLANs and trunk/native VLANs. Because 3311 falls inside the valid configurable VLAN ID range, it is the only valid option listed. Option A, 4096, is invalid because it is above the supported VLAN ID range. Option B, 0, is invalid because configurable VLAN IDs begin at 1. Option C, 32768, is far outside the supported VLAN ID range and cannot be configured as a VLAN ID on a CX switch. This question tests the standard IEEE 802.1Q VLAN ID range as applied in HPE Aruba Networking CX configuration. The supported configurable VLAN range is 1 through 4094, with VLAN 1 commonly used as the default VLAN and VLAN IDs such as 3311 available for administrator-defined VLANs.
