HPE6-A86 Exam Dumps - HPE Network Switching Associate Exam

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.

The correct answer is D. UDP 162. SNMP monitoring commonly uses two different UDP ports depending on direction and purpose. SNMP polling requests and responses use UDP 161, while SNMP traps and notifications are sent to a monitoring or management station on UDP 162. The question specifically asks about sending monitoring alerts using SNMP, which refers to SNMP traps or notifications from the switch to the Network Monitoring System. HPE Aruba Networking AOS-CX SNMP documentation states that the snmp-server host command configures a trap or inform receiver to which the SNMP agent sends SNMP traps or informs. The same documentation identifies the UDP port parameter for notifications and lists the default as 162. Therefore, the required firewall allowance for SNMP alert notifications from CX switches to the NMS is UDP 162. Option A is incorrect because TCP 161 is not the standard SNMP polling transport. Option B and option C use incorrect ports and protocols for SNMP alert delivery.

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 VSF ports automatically forward the traffic for configured VLANs. In HPE Aruba Networking CX VSF, the VSF link ports are dedicated stack-fabric interfaces between VSF members. They are not configured like normal access or trunk ports for user VLAN forwarding. HPE Aruba Networking Central documentation for AOS-CX ports and LAGs notes that VLAN mode options such as access or trunk are not visible for VSF ports, which confirms that VSF ports are not manually configured as normal VLAN trunks. Once the VSF stack is formed, the stack operates as one logical switch, and the VSF links carry the necessary internal stack traffic automatically, including traffic associated with configured VLANs. Option B is incorrect because you do not configure VSF ports as trunk ports with vlan trunk allowed all. Option C is incorrect because vsf-sync is not required for VLAN forwarding across VSF links. Option D is incorrect because VLAN 4095 is not manually configured on VSF links for this purpose.

The correct answer is B. Switch port. The Physical Layer of the OSI model is concerned with the physical transmission of signals across network media, including electrical or optical signaling, cabling, connectors, transceivers, and physical interfaces. HPE Aruba Networking hardware and transceiver documentation describes switch ports, transceiver slots, copper cabling, fiber-optic cabling, and link LEDs as physical connection components. A switch port is therefore the only option listed that belongs directly to the Physical Layer. Option A, URL, is associated with application-level access to web resources and is not a Physical Layer item. Option C, IP address, belongs to Layer 3 because it is used for logical addressing and routing. Option D, TCP port, belongs to Layer 4 because TCP ports identify transport-layer application sessions. Although a switch port may participate in Layer 2 switching after a link is established, the physical connector/interface itself is part of the Layer 1 network infrastructure. This makes “switch port” the correct answer from the listed options.

The correct answer is C. Commands - show interface error-statistics. Because the users and the document management server are in the same subnet, traffic is switched locally rather than routed across multiple Layer 3 hops. If packet loss is suspected during file uploads, the most useful verification is to inspect interface error counters on the switch ports involved. HPE Aruba Networking AOS-CX documentation includes the show interface < IFNAME > error-statistics command, which displays interface error statistics such as receive and transmit errors, CRC/FCS errors, drops, runts, giants, and related counters. HPE Aruba Networking Central documentation states that the Commands tab can run troubleshooting commands on managed devices and show the output in the Device Output section. A cable test may help detect physical cabling faults, but it does not directly confirm packet loss counters. Traceroute is less useful within the same subnet. Ping can show reachability loss, but interface error statistics provide better evidence of switch-port packet errors causing performance problems.

The correct answer is C. Default VLAN 1 is created by default. HPE Aruba Networking AOS-CX documentation states that all switch ports are part of access VLAN 1 by default. This confirms that VLAN 1 exists in the factory-default configuration and is the default VLAN used by switch ports. Option B is incorrect because AOS-CX VSF documentation states that users cannot disable VSF and that a factory-default switch boots as a VSF-enabled device with member ID 1 on supported VSF platforms. Option A is not the best answer because static routing is not described as the defining factory-default setting in the same way VLAN 1 is. Static routes are administrator-created route entries, but the clearly documented default behavior in the listed choices is that VLAN 1 exists by default. Option D is incorrect because multicast routing is not enabled by default as a general factory-default behavior. Therefore, the statement that correctly describes the factory default is that default VLAN 1 is created and switch ports belong to it by default.

The correct answer is B. LLDP. Link Layer Discovery Protocol, or LLDP, is the most useful feature for building a physical connectivity diagram because it helps identify directly connected neighboring devices and their interface relationships. HPE Aruba Networking Central documentation notes that LLDP is enabled by default on switches and is used to display AOS-CX switches in topology views. Aruba Central’s topology feature provides a graphical representation of the site, including the network layout and device details. This makes LLDP directly relevant to discovering and documenting physical network connections. Option A, MSTP, is a spanning tree protocol used to prevent Layer 2 loops and manage redundant paths, not to document physical connectivity. Option C, ZTP, is used for automated device provisioning, not topology discovery. Option D, L2TP, is a tunneling protocol and is unrelated to creating physical connectivity diagrams. Therefore, LLDP is the best answer because it provides neighbor discovery information that can be used to map how network devices are physically connected.
