Controller Architecture Flashcards

Which Aruba Mobility Controller model is designed specifically for branch office deployments with limited power and space?

Answer: 7005

The 7005 is Aruba's entry-level hardware controller suited for small branch offices with minimal footprint requirements.

In an Aruba controller-based WLAN, which protocol do APs use to communicate with the controller?

Answer: CAPWAP

CAPWAP (Control and Provisioning of Wireless Access Points) is the standard protocol used for AP-to-controller communication in Aruba deployments.

What is the primary role of the Mobility Master (MM) in an Aruba Mobility Master-based architecture?

Answer: Provide centralized policy and configuration management

The Mobility Master provides centralized configuration, policy management, and visibility across all Mobility Controllers in the hierarchy.

Which Aruba controller component is responsible for enforcing firewall policies on user traffic?

Answer: Policy Enforcement Firewall (PEF)

The Policy Enforcement Firewall (PEF) module on the controller inspects and enforces stateful firewall policies on wireless user traffic.

In a hierarchical Aruba deployment, a Managed Device (MD) refers to which component?

Answer: A Mobility Controller managed by Mobility Master

A Managed Device is a Mobility Controller that receives its configuration and policies from a Mobility Master.

What happens to wireless client traffic when an Aruba AP operates in tunnel mode?

Answer: Traffic is encrypted and tunneled to the controller

In tunnel mode, the AP encapsulates all client traffic in a GRE or CAPWAP tunnel and forwards it to the Mobility Controller for processing.

Which Aruba architecture allows APs to switch client traffic locally without sending it to a central controller?

Answer: Distributed forwarding (split-tunnel or bridge mode)

Distributed forwarding (bridge or split-tunnel mode) allows APs to switch some or all client traffic locally, reducing WAN bandwidth consumption.
