What is the recommended VSF topology? (Select two.)
Answer(s): B,E
Only: Daisy chain plus MAD and ring are the recommended VSF topologies for Aruba switches. They provide high availability and redundancy for the VSF stack. MAD (Multiple Active Detection) is a mechanism to detect and resolve split-brain scenarios in a VSF stack.

Which feature can network administrators use to centralized RF planning and optimization service when using an Aruba mobility master architecture?
Answer(s): C
AirMatch is a feature that provides centralized RF planning and optimization service for Aruba wireless networks. It uses cloud-based algorithms and machine learning to optimize the RF performance and user experience.
https://www.arubanetworks.com/assets/ds/DS_AirMatch.pdf In Aruba networks, the recommended Virtual Switching Framework (VSF) topologies include the daisy chain plus Multi-Active Detection (MAD) and the ring topology. The daisy chain topology with MAD provides a straightforward and effective way to connect multiple switches in a series while ensuring there is a mechanism in place (MAD) to detect and handle situations where more than one switch in the VSF might become active simultaneously. The ring topology offers redundancy by creating a looped connection pattern among the VSF members, enhancing network resilience and reliability.
Which statement about manual switch provisioning with Aruba Central is correct?
Manual switch provisioning in Aruba Central can be done without relying on DNS services, but it does require DHCP to assign IP addresses to the switches. DHCP is essential for the switches to obtain an IP address, which is necessary for them to communicate within the network and with Aruba Central for management and configuration purposes. DNS, on the other hand, is not strictly required for manual provisioning as direct IP addresses or other methods can be used to connect to Aruba Central or other management interfaces.
Where are wireless client roaming decisions made?
Answer(s): A
Wireless client roaming decisions are made by the client device based on its own criteria, such as signal strength, noise level, data rate, etc. The network can influence the client's roaming decision by providing information such as neighbor reports, load balancing, band steering, etc., but the final decision is up to the client.
https://www.arubanetworks.com/techdocs/Instant_86_WebHelp/Content/instant-ug/wlan- roaming/client-roaming.htmWireless client roaming decisions are primarily made by the client device itself. The client device monitors the signal strength and quality of the current connection and decides to roam to a different Access Point (AP) when the current signal deteriorates below a certain threshold or a better option is available. While APs and controllers can provide information and support for roaming decisions through protocols like 802.11k and 802.11v, the ultimate decision to roam is made by the client device based on its algorithms and thresholds.
