HPE6-A86 Exam Dumps - HP Aruba Certified Switching Associate (ACSA) V1 Questions and Answers

The correct answer is D. To configure a physical interface as a Layer 3 routed port on an HPE Aruba Networking CX 6300 switch, the interface must be placed in routing mode and assigned an IP address directly. This creates a routed interface rather than a bridged Layer 2 port. HPE Aruba Networking AOS-CX examples show routed physical interfaces configured with routing, followed by an ip address, and then no shutdown. The same examples contrast this with Layer 2 ports, which use no routing and VLAN commands such as vlan access or vlan trunk. Option A is incorrect because no routing makes the interface a Layer 2 interface, so assigning an IP address directly is not the correct routed-port configuration. Options B and C are incorrect because vlan access 1 configures the port as a bridged access port. The requirement specifically says the switch should be configured without a bridged port, so the correct CX configuration is a routed physical interface using routing with the IP address configured directly on the port.

The correct answer is D. By default, all VLAN traffic is tagged to traverse a trunk link except the native VLAN. In HPE Aruba Networking AOS-CX, a trunk interface can carry traffic for multiple VLANs, and VLAN tagging is used to identify traffic from different VLANs across the trunk. However, the native VLAN is the exception. HPE Aruba Networking documentation explains that the native VLAN is the VLAN to which incoming untagged traffic is assigned, and by default VLAN 1 is assigned as the native VLAN for trunk interfaces. This means normal trunk behavior is that VLAN traffic is tagged, while native VLAN traffic can be untagged unless configured otherwise. Option A is incomplete because it ignores native VLAN behavior. Option B is incorrect because the native VLAN concept applies to trunk interfaces generally, not only when a port is part of a LAG. Option C is incorrect because VLAN trunking applies to Layer 2 interfaces, not routed ports. Therefore, the default trunk behavior is tagged VLAN traffic except for the native VLAN.

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.

The correct answer is A. The CX 6300M VSF stack is the Layer 3 gateway for VLAN 200 clients, so the DHCP relay configuration must be applied to interface vlan 200, the SVI for the client VLAN. The SVI should use an address in the client subnet, such as 192.168.200.1/24, and the remote DHCP server should be defined with the AOS-CX ip helper-address command. HPE Aruba Networking AOS-CX documentation states that ip helper-address < IPV4-ADDR > defines the address of a remote DHCP server or DHCP relay agent and that the DHCP relay agent forwards DHCP client requests to the defined servers. Option B is incorrect because VLAN 1 is not the VLAN 200 client gateway. Options C and D are incorrect because dhcp-relay server is not the correct AOS-CX command shown for configuring IPv4 DHCP relay on the SVI. The correct configuration is ip helper-address 192.168.1.100 under interface vlan 200.

The correct answer is B. Authentication, Authorization, and Accounting. HPE Aruba Networking AOS-CX documentation defines AAA as the security framework used to manage user access, enforce privileges, and log user access records. Authentication identifies users and validates their credentials. Authorization determines what authenticated users are allowed to do, such as which commands or services they can access. Accounting records user activity, access events, or resource usage for auditing and tracking. AAA can use local user accounts or remote authentication services such as RADIUS and TACACS+, depending on the switch configuration and security design. Option A is incorrect because AAA does not stand for Aruba Authentication Algorithm. Option C is not the correct expansion of the acronym. Option D uses similar-sounding terms but is not the official meaning. In HPE Aruba Networking documentation, AAA means Authentication, Authorization, and Accounting.

The correct answer is A. CX 6300. The requirement asks for a fixed 1U access switch that can support 25G speeds toward the aggregation layer. HPE Aruba Networking CX 6300 switches are described as stackable switches suitable for enterprise access, aggregation, core, and data center top-of-rack deployments. HPE QuickSpecs for the CX 6300 list 1U models with SFP/SFP+/SFP28/SFP56 transceiver support, including 1G, 10G, 25G, and 50G uplink capability depending on the model. This makes the CX 6300 the best fit among the options. The CX 6400 is not the best answer because it is a modular chassis platform, not a fixed 1U switch. The CX 6100 is an entry-level Layer 2 access switch with 10G uplinks, not 25G. The CX 6200 supports access switching with uplinks up to 10G, so it also does not satisfy the 25G uplink requirement. Therefore, the initial proposal should be the CX 6300 family.

The correct answer is A. operators. HPE Aruba Networking AOS-CX documentation for the CX 8400 identifies built-in user groups that exist by default on the switch. These include administrators, operators, and auditors. The operators group has limited privileges, such as basic display-only CLI access and the ability to view nonsensitive switch configuration information. It does not have full switch configuration privileges. The other options—helpdesk, servicedesk, and support—are not listed as built-in default user groups for the CX 8400. Those names could be created manually as custom local user groups in some environments, but they are not default AOS-CX groups. Therefore, from the available choices, the default group is operators.

The correct answer is C. Automates root cause analytics. HPE Aruba Networking AOS-CX documentation describes the Network Analytics Engine, or NAE, as a framework within AOS-CX switches that automates the detection of issues and automates root cause analysis. NAE agents monitor switch resources, events, configuration, protocol states, and other operational data to help identify issues faster. This helps administrators move from manual troubleshooting to analytics-driven troubleshooting directly on the switch. Option A is not the best answer because NAE is not simply a feature that automatically creates tech-support diagnostic files. Option B is incorrect because automated configuration backups are not the main purpose of NAE. Option D is incorrect because NAE does not primarily create support events in the HPE Aruba Networking Support Portal. Its purpose is local switch analytics, issue detection, and root cause analysis. Therefore, the best description is that NAE automates root cause analytics.

The correct matches are 802.3af for 15.4W, 802.3at for 30W, 802.3bt Type 3 for 60W, and 802.3bt Type 4 for 90W. HPE Aruba Networking AOS-CX PoE documentation explains that PoE powered devices are divided into different types and classes according to their power requirements. It identifies Type 1 as supplying a maximum of 15.4W from the power sourcing equipment, which corresponds to IEEE 802.3af. Type 2 supplies a maximum of 30W, which corresponds to IEEE 802.3at. Type 3 supplies a maximum of 60W and Type 4 supplies a maximum of 90W, both under IEEE 802.3bt. These values are important when selecting switch PoE capability for devices such as access points, cameras, sensors, phones, and other powered devices. The switch must have both the per-port PoE capability and enough total PoE power budget to support the connected devices.

The correct answer is C. The existing 5406R configuration uses an LACP trunk, with VLANs 100, 200, and 300 tagged and VLAN 50 untagged. The equivalent HPE Aruba Networking AOS-CX configuration is to create a LAG, enable LACP using lacp mode active, allow the tagged VLANs on the trunk, and configure VLAN 50 as the native VLAN. In AOS-CX, the vlan trunk native < VLAN-ID > command assigns the native VLAN to the trunk or LAG interface. Native VLAN traffic is untagged unless native VLAN tagging is specifically configured. HPE Aruba documentation also shows the command syntax for assigning native VLANs to LAG interfaces and the use of vlan trunk allowed for the VLANs carried on the trunk. Option A and option B are incorrect because lacp mode enable and the shown native VLAN syntax are not the correct CX syntax. Option D is less correct because VLAN 50 is the native untagged VLAN and does not need to be included with the tagged VLAN list. The correct CX equivalent is therefore LACP active, allowed VLANs 100, 200, and 300, and native VLAN 50.
