The correct answer is B. Transport Layer. Data segmentation is a Transport Layer function. At Layer 4, protocols such as TCP divide application data into smaller pieces called segments so that data can be transported between endpoints. The Transport Layer also uses TCP and UDP port numbers to identify application conversations between hosts. HPE Aruba Networking AOS-CX ACL documentation references TCP/UDP ports as Layer 4 ports, which aligns transport-layer port usage with the Transport Layer. The Application Layer provides user-facing application services, but it does not perform transport segmentation. The Network Layer handles logical IP addressing and routing. The Data Link Layer handles Ethernet framing, MAC addressing, and local delivery on a network segment. Therefore, when the question asks where data segmentation occurs in the OSI model, the correct answer is the Transport Layer. ( arubanetworking.hpe.com )

The correct answer is D. VSF stacking is supported within the same switch family members. HPE Aruba Networking AOS-CX VSF documentation states that a VSF stack supports combinations of models only within a supported switch family. For example, supported 6200 family models can stack with other supported 6200 family models, and supported 6300 family models can stack with other supported 6300 family models. The documentation also states that stacking is not supported across switch families. This means a VSF stack cannot mix unrelated platforms, such as chassis and fixed switches, or combine older AOS-S/Provision switches with AOS-CX switches in the same VSF stack. Option A is incorrect because VSF does not use proprietary backplane cabling; it uses supported Ethernet links, and the supported speeds depend on the switch family. Option B is incorrect because chassis and fixed platforms are not mixed in one VSF stack. Option C is incorrect because existing Provision/AOS-S switches cannot simply add CX switches as members in the same VSF stack.

The correct answer is D. CX 8400. The requirement asks for a chassis solution, 100G speeds to the aggregation layer, and a maximum size of 10U. HPE Aruba Networking describes the CX 8400 as a core and aggregation switch with line-rate 10GbE, 25GbE, 40GbE, and 100GbE connectivity in a compact 8-slot chassis. The installation guide also identifies the CX 8400 as an eight-slot chassis platform for core and aggregation switching. This satisfies both the 100G requirement and the physical-size requirement because 8U is below the 10U maximum. The CX 10000, CX 9300, and CX 8360 are fixed-form-factor platforms rather than chassis solutions, so they do not match the customer’s chassis requirement. Therefore, the best initial proposal from the listed options is the HPE Aruba Networking CX 8400.

The correct answer is D. As a response to the broadcast DHCP query. DHCP clients initially do not have an IP address, so they commonly use broadcast DHCP discovery/request traffic to locate a DHCP server on the local network. HPE Aruba Networking documentation for DHCP relay explains that when a DHCP client broadcasts a request, the DHCP relay agent on the switch receives the packets and forwards them to the DHCP server as unicast requests. In this scenario, the access points are in VLAN 50, and VLAN 50 also contains DHCP servers. Because the DHCP server is on the same local management VLAN as the APs, the APs can obtain addresses through the normal DHCP broadcast process within that VLAN. Anycast and multicast are not used for the basic DHCP address request in this scenario. A unicast DHCP relay message can occur between a relay agent and a DHCP server when the server is on another subnet, but the client-side DHCP discovery begins as broadcast traffic.

The correct answer is A. 10G-DAC. The limiting device in this connection is the CX 6200. HPE Aruba Networking CX 6200 models use built-in high-speed uplinks, and the CX 6200 product listings identify models with 4SFP+ uplinks. SFP+ uplinks support 10G, not 25G, 50G, or 100G single-port connectivity. HPE Aruba Networking transceiver guidance also notes that CX 6200 switches support split-side SFP connections only in available 10G-capable SFP ports, and that 50G transceivers can only be used in ports capable of 50G speeds, such as SFP56-capable ports. Therefore, even though the CX 8100 supports higher-speed connectivity options, the shared validated single-port option between the two switch families is 10G over DAC for a short 3-meter connection. Option B is incorrect because the CX 6200 does not have 100G ports. Option C is incorrect because 25G-LR is not the best validated 3-meter option and exceeds the CX 6200 SFP+ port capability. Option D is incorrect because 50G-DAC requires 50G-capable ports.

The correct answer is C. The management port is used for multi-active detection. The show vsf output clearly shows Split Detection Method : mgmt, which means the stack is using the management interface as the VSF split-detection method. HPE Aruba Networking AOS-CX VSF documentation states that VSF split detection provides a mechanism for stack fragments to discover each other if a stack split occurs. Once fragments are discovered, the fragment with the primary member remains active, while the other fragment becomes inactive and its non-VSF interfaces are brought down to avoid duplicate MAC or IP addresses and reduce network disruption. The same guide states that the 6200 and 6300 switch series support split detection through the management interface and that the CLI command to enable it is vsf split-detect mgmt. Option A is incorrect because the output does not show peer-switch-based detection. Option B is incorrect because “Status: No Split” is the current state, not the detection method. Option D is incorrect because a ring changing to a chain is a topology change, but the configured integrity method shown is management-based split detection. ( arubanetworking.hpe.com )

The correct answer is A. CX 6300. The configuration shown uses OSPFv2 with a process ID, redistribution of connected routes, and a route map. HPE Aruba Networking AOS-CX IP Routing documentation for the CX 6300 and related higher CX platforms includes OSPFv2 routing commands such as router ospf and redistribute connected route-map. The same command documentation shows redistribution into OSPF with a route map as a supported configuration. By contrast, the AOS-CX IP Routing Guide for lower platforms such as the 4100i, 6000, and 6100 includes OSPF command information showing platform support for OSPF on 5420 and 6200, not on the 4100i, 6000, or 6100. Therefore, from the choices provided, the CX 6300 is the switch family that supports creating this OSPF redistribution configuration. The CX 6000 and CX 6100 are access-layer switches and are not the correct choice for this OSPF route redistribution example.

The correct answer is B. The switch control plane is shared. HPE Aruba Networking documentation explains that Virtual Switching Framework, or VSF, stacks multiple individual switches into a single logical device using standard Ethernet links. Once the VSF stack is formed, the interconnected switches operate as one virtual switch with a single control plane. HPE Aruba documentation also describes VSF as providing a single point of management access with a shared control plane across all stack members. Option A is incorrect because member IDs are part of the VSF configuration and may be assigned or changed during stack setup. Option C is incorrect because VSF is not universally limited to two members; supported stack size depends on the switch family and software support. Option D is incorrect because an independent management plane describes VSX more than VSF. HPE’s VSF-versus-VSX comparison identifies VSF as having a single management plane, while VSX has dual management planes.

The correct answer is C. auditors. HPE Aruba Networking AOS-CX documentation for the 6200, 6300, and 6400 switch series identifies three built-in user groups: administrators, operators, and auditors. These built-in groups have fixed privileges. The administrators group has full privileges, including full CLI access, firmware upgrades, configuration viewing, configuration changes, and user account management. The operators group has no switch configuration privileges and is mainly limited to basic display-only access and viewing nonsensitive configuration information. The auditors group is restricted to audit-related functions. Since the question asks which user group exists by default on a CX 6400 Series switch, “auditors” is the only listed option that matches the HPE Aruba Networking AOS-CX built-in groups. The other options—read-only, restricted, and reporting—are not listed as default built-in AOS-CX user groups for the CX 6400 platform. This makes option C the verified answer.

The correct answer is A. Root bridge. In a switched infrastructure using Spanning Tree Protocol, the root bridge is the central reference point for calculating the loop-free Layer 2 topology. HPE Aruba Networking AOS-CX documentation explains that device roles, such as root bridge or leaf node, should be planned by adjusting spanning tree instance priority. It also notes that the placement of root bridges is important in a Layer 2 network domain because deterministic root and secondary root bridges provide predictability and protection. Switches calculate their best path toward the root bridge based on spanning tree information such as bridge priority, path cost, and port roles. This calculation determines which ports forward and which ports block to prevent loops. Option B is incorrect because a designated bridge or designated port forwards traffic for a segment but does not define the overall topology reference point. Option C is incorrect because “alternative bridge” is not the entity that defines best path selection. Option D is incorrect because “common bridge” is not the correct STP role.
