HP Updated HPE6-A86 Exam Questions and Answers by ismael

The correct answer is B. CX 8100 Series switches do not support VSF. The error appears because the vsf command is not valid on a platform that does not support Virtual Switching Framework. HPE Aruba Networking documentation identifies VSF as supported on specific access-switch platforms such as the CX 6200 and CX 6300 families. For higher-end aggregation and core platforms, including the CX 8100, HPE Aruba Networking uses Virtual Switching Extension, or VSX, rather than VSF. Official HPE Aruba Networking Central documentation states that VSX is supported on AOS-CX 6400, 8100, 8320, 8325, 8360, 8400, 9300, and 10000 switch series. Other AOS-CX documentation for 8xxx switch families also notes that VSF is not supported on those switches. Option A is incorrect because physical VSF links are not the reason the command is rejected. Option C is incorrect because VSF cannot be globally enabled on CX 8100. Option D is incorrect because this is a platform-support limitation, not a firmware issue.

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 C. The wrong subnet mask has been configured. The PC is configured with IP address 10.211.55.151 and subnet mask 255.255.255.0, which is a /24 network. However, the HPE Aruba Networking CX switch SVI for VLAN 55 is configured as 10.211.55.1/25. A /25 mask divides the 10.211.55.0/24 range into two subnets: 10.211.55.0–10.211.55.127 and 10.211.55.128–10.211.55.255. The switch gateway address 10.211.55.1/25 is in the first /25 subnet, while the PC address 10.211.55.151 is in the second /25 subnet. This means the PC and its configured default gateway are not actually in the same subnet from the switch’s perspective. HPE Aruba Networking AOS-CX CLI documentation shows IP addressing on interfaces using prefix-length notation, such as /25, which defines the subnet size. Option A is incorrect because the port is configured with no shutdown and no STP error state is shown. Option B is incorrect because an access port does not require VLAN tagging from the PC. Option D is incorrect because a PC normally uses a default gateway, not a static route, for Internet access.

The correct answer is A. Must be manually configured. HPE Aruba Networking AOS-CX documentation states that static routes are manually configured in the routing table. A static route defines a destination network and the next-hop address or exit interface that the switch should use to forward traffic. Static routes are useful in small, simple, or predictable networks because they are straightforward and do not require a dynamic routing protocol to exchange route information. Option B is incorrect because automatically learned routes are associated with dynamic routing protocols, such as OSPF or BGP, not static routing. Option C is incorrect because static routes usually have low processing overhead compared to dynamic routing protocols, since the switch does not need to run neighbor discovery, exchange routing updates, or calculate topology changes. Option D is incorrect because static routes do not automatically respond to network topology changes unless supported by an additional tracking mechanism or manually changed by an administrator. Therefore, the defining characteristic of a static route is manual configuration.
