QuestionQ4

WLAN

A university operates a campus with several buildings divided into east and west wings that are L3-separated. The east wing has 1600 APs, while the west wing has 1200 APs. Each wing has one gateway cluster managed by HPE Aruba Networking Central, and each cluster contains a single 7210 mobility gateway. The gateways use DHCP relay and route every client VLAN.

A new business-critical, real-time faculty application requires users to roam within their wings, but not between wings, with no disconnections or added delay.

Which changes must the network administrator make to meet this requirement successfully, without performance degradation and in accordance with best practices?

Choose two
Explanation

Seamless roaming in a gateway deployment requires all APs in the roaming domain to tunnel to the same gateway cluster and requires the client VLANs and broadcast domains to be common across the cluster. L2 forwarding with the client VLANs permitted on the gateway uplinks preserves a client’s VLAN, IP address, and default gateway during an intra-wing roam. Adding a second 7210 to each cluster provides the clustered stateful failover required for a business-critical service; a 7210 supports up to 2,048 devices per gateway, covering both 1,600-AP and 1,200-AP wings.
