HPE6-A86 Exam Questions & Answers

The correct answer is D. VSF stacking is supported within the same switch family members. HPE Aruba Networking AOS-CX VSF documentation states that a VSF stack supports combinations of models only within a supported switch family. For example, supported 6200 family models can stack with other supported 6200 family models, and supported 6300 family models can stack with other supported 6300 family models. The documentation also states that stacking is not supported across switch families. This means a VSF stack cannot mix unrelated platforms, such as chassis and fixed switches, or combine older AOS-S/Provision switches with AOS-CX switches in the same VSF stack. Option A is incorrect because VSF does not use proprietary backplane cabling; it uses supported Ethernet links, and the supported speeds depend on the switch family. Option B is incorrect because chassis and fixed platforms are not mixed in one VSF stack. Option C is incorrect because existing Provision/AOS-S switches cannot simply add CX switches as members in the same VSF stack.

The correct answer is B. Configure an IP helper for the DHCP server. The IoT device is connected to VLAN 100, whose Layer 3 SVI is 10.100.1.1/24. The DHCP server is 10.200.1.51, which is in a different subnet. DHCP clients initially use broadcast messages to discover a DHCP server, and those broadcasts do not cross Layer 3 boundaries by default. HPE Aruba Networking AOS-CX documentation explains that DHCP relay forwards DHCP client requests to configured DHCP servers, and that the ip helper-address command defines the address of a remote DHCP server or relay agent. The documentation also states that IP helper addresses can be configured on Layer 3 interfaces, Layer 3 VLAN interfaces, and LAG interfaces. Therefore, the correct fix is to configure ip helper-address 10.200.1.51 under interface vlan100. Disabling STP is not appropriate and could create Layer 2 loop risk. A static route may be needed for reachability in some designs, but it does not relay DHCP broadcasts. Broadcast-to-unicast conversion is not the required AOS-CX DHCP relay configuration.

The correct answer is A. On HPE Aruba Networking AOS-CX switches, the out-of-band management interface is configured under interface mgmt. For a static IPv4 address on the management interface, the correct command is ip static, not ip address. HPE Aruba Networking documentation shows the management interface configuration using interface mgmt, then ip static

The correct answers are B and E. On HPE Aruba Networking AOS-CX switches, configuration changes are made to the running configuration. To ensure those changes persist after a reboot, the running configuration must be saved to the startup configuration. HPE Aruba Networking documentation states that write memory saves the running configuration to the startup configuration and is an alias of copy running-config startup-config. The copy running-config startup-config command copies the current running configuration into the startup configuration, overwriting the existing startup configuration if one is already present. Option A, commit confirm, is not the AOS-CX command used to save the current running configuration for reboot persistence. Option C, save force, is not the correct AOS-CX command for this task. Option D is the reverse operation; copy startup-config running-config would copy the saved startup configuration into the active running configuration rather than saving current changes for the next reboot. Therefore, the two valid commands are write memory and copy running-config startup-config.

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.
