HPE Network Switching Associate Exam 認定 HPE6-A86 試験問題 (Q74-Q79):

質問 # 74
Users report poor performance when uploading files to their document management server in the same subnet.
You suspect packet loss is causing the problem.
Which tool in HPE Aruba Networking Central can you use to confirm this?

正解：A

解説：
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.


質問 # 75
A customer requires a network upgrade to replace their existing access switches. The new solution must support 25G speeds to the aggregation layer, with a maximum physical space of 1U, and it must be a fixed switch solution.
Which HPE Aruba Networking CX switch model would you initially propose?

正解：C

解説：
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.


質問 # 76
Which aspect of Layer 3 analysis involves evaluating the operation and effectiveness of protocols such as RIP, OSPF, EIGRP, and BGP in dynamically exchanging routing information and building routing tables?

正解：B


質問 # 77
Refer to the diagram below.

After a recent network change, the helpdesk reports that some users could not connect to the print server, Server-1, which is in VLAN 20. After further investigation, you find that only devices directly connected to Access-2 are affected.
Which part of the network should you investigate?

正解：D

解説：
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.


質問 # 78
Which options accurately describe MAC address and ARP tables? (Select two)

正解：D、E
