A network engineer recently identified that a wired device connected to a CX switch is misbehaving on the network. To address this issue, a new HPE Aruba Networking ClearPass policy has been put in place to prevent this device from connecting to the network again.Which two steps need to be implemented to allow ClearPass to perform a CoA and change the access for this wired device? (Choose two.)
Answer(s): C,E
To allow ClearPass to perform Change of Authorization (CoA) on a CX switch, dynamic authorization must be enabled on the switch, so it can accept CoA requests from ClearPass. Additionally, to immediately remove the misbehaving device and apply new access rules, bouncing the switchport (shutting and re-enabling the port) ensures the device is reauthenticated and subject to updated policy enforcement.
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2? (Choose two.)
Answer(s): A,D
When a client roams from AP1 to AP2, AP1 first caches the client’s session and security information, which is sent to the Key Management service to facilitate fast roaming. After roaming, the client associates and authenticates with AP2, allowing the session to resume seamlessly and securely.
Two AOS-CX switches are configured with VSX at the Access-Aggregation layer, where servers attach to them. An ASVI interface is configured for VLAN 10 and serves as the default gateway for VLAN 10. The ISL link between the switches fails, but the keepalive interface functions. Active gateway has been configured on the VSX switches.What is correct about access from the servers to the Core? (Choose two.)
Answer(s): E,F
In AOS-10, which session-based ACL below will only allow ping from any wired station to wireless clients but will not allow ping from wireless clients to wired stations? The wired host ingress traffic arrives on a trusted port.
Answer(s): A
The session ACL in image 1 first denies all ICMP traffic (any any svc-icmp deny), then explicitly permits ICMP from any wired station to a wireless client (any user svc-icmp permit). This ensures only pings from wired to wireless are allowed, but not from wireless to wired.
Which statement best describes QoS?
Answer(s): B
Quality of Service (QoS) is primarily about identifying particular types of network traffic and applying policies to give them special treatment - such as prioritization, guaranteed bandwidth, or lower latency - to meet service requirements.
