Score Higher on Verified HPE6-A86 | HPE Network Switching Associate Exam Questions with Answers

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 D. Allowed VLANs between access switches. The diagram shows Server-1 connected to Access-2 in VLAN 20 and PC-1 connected to Access-1. The inter-switch link between Access-1 and Access-2 is shown as a trunk carrying VLANs 1, 10, and 20. If users on Access-1 cannot reach Server-1 in VLAN 20 after a recent change, while devices directly connected to Access-2 are not affected, the most likely issue is that VLAN 20 is not being correctly carried across the trunk between the access switches. HPE Aruba Networking AOS-CX documentation states that vlan trunk allowed defines which VLAN traffic is allowed across a trunk interface. It also explains that allowed VLANs are the VLANs that can be transported by the trunk; if a required VLAN is missing from the allowed list, that VLAN’s traffic will not traverse the trunk. Option A is less likely because devices directly connected to Access-2 can access Server-1, indicating Server-1’s local VLAN placement is probably correct. Option B is unlikely because a down trunk would affect more VLANs than just access to VLAN 20. Option C is not supported by the symptom pattern.

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.
