HP HPE6-A86 Exam With Confidence Using Practice Dumps

The correct answer is A. CX 6400. The requirement calls for a chassis-based core switch that can scale to a 12U chassis and support 100G speeds toward the aggregation layer. HPE Aruba Networking CX 6400 QuickSpecs identify the CX 6400 as a modular switch family and include the larger CX 6410 chassis option, which is a 10-slot chassis platform. HPE also lists CX 6400 40/100GbE QSFP28 line modules, which provide the required 100G connectivity. This makes CX 6400 the correct fit for a chassis solution that can scale to the requested physical size and provide 100G uplinks. The CX 10000, CX 9300, and CX 8325 are fixed-form-factor platforms, not modular chassis solutions, so they do not match the stated chassis requirement. Therefore, the best initial proposal is the HPE Aruba Networking CX 6400.

The correct answer is B. 2. The diagram shows two VLANs: VLAN 10 and VLAN 20. In Ethernet switching, each VLAN represents a separate Layer 2 broadcast domain. HPE Aruba Networking documentation defines a VLAN as a single Layer 2 network that can be partitioned to create multiple distinct broadcast domains, isolated from each other unless traffic passes through a router or Layer 3 interface. In this diagram, PCs A and B are in VLAN 10, so they share one broadcast domain. PCs C and D are in VLAN 20, so they share a second broadcast domain. The Layer 3 switch has SVIs for VLAN 10 and VLAN 20, which allow routing between the two VLANs, but the SVIs do not merge the broadcast domains. They provide Layer 3 gateways for each VLAN. Therefore, the number of broadcast domains is based on the number of VLANs shown, not the number of PCs, switch links, or SVIs. Since there are two VLANs, there are two broadcast domains.

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.
