NEW QUESTION # 36
A company has HPE Aruba Networking APs running AOS-10 that connect to AOS-CX switches. The APs will:
. Authenticate as 802.1X supplicants to HPE Aruba Networking ClearPass Policy Manager (CPPM)
. Be assigned to the "APs" role on the switches
. Have their traffic forwarded locally
What information do you need to help you determine the VLAN settings for the "APs" role?
- A. Whether the switches have established tunnels with an HPE Aruba Networking gateway
- B. Whether the APs bridge or tunnel traffic on their SSIDs
- C. Whether the APs have static or DHCP-assigned IP addresses
- D. Whether the switches are using local user-roles (LURs) or downloadable user-roles (DURs)
Answer: B
Explanation:
To determine the VLAN settings for the "APs" role on AOS-CX switches, it is crucial to know whether the APs bridge or tunnel traffic on their SSIDs. If the APs are bridging traffic, the VLAN settings on the switch need to align with the VLANs used by the SSIDs. If the APs are tunneling traffic to a controller or gateway, the VLAN settings might differ as the traffic is encapsulated and forwardedthrough the tunnel. Understanding this aspect ensures that the VLAN configuration on the switches correctly supports the traffic forwarding method employed by the APs.
NEW QUESTION # 37
Assume that an AOS-CX switch is already implementing DHCP snooping and ARP inspection successfully on several VLANs.
What should you do to help minimize disruption time if the switch reboots?
- A. Save the IP-to-MAC bindings to external storage.
- B. Configure the switch to act as an ARP proxy.
- C. Create static IP-to-MAC bindings for the DHCP and DNS servers.
