ACMA Mobility Solutions 3 — Questions and Answers
Question 1: In Aruba's split-tunnel configuration for Remote APs, what traffic is sent locally rather than tunneled to the controller?
- Corporate intranet traffic
- Internet-bound traffic (Correct answer)
- Management traffic
- VoIP traffic
Correct answer: Internet-bound traffic
In split-tunnel mode, internet-bound traffic is forwarded locally at the Remote AP, while corporate traffic is tunneled back to the Mobility Controller.
Question 2: What Aruba feature enables different security policies to be applied based on the user's role rather than their VLAN?
- VLAN pooling
- Role-Based Access Control (RBAC) (Correct answer)
- Dynamic Segmentation
- Firewall Policy Enforcement
Correct answer: Role-Based Access Control (RBAC)
RBAC in Aruba assigns users to roles upon authentication, and each role carries firewall rules, bandwidth limits, and VLAN assignments independent of physical port.
Question 3: Which 802.11 standard introduced MU-MIMO technology for downlink transmissions to multiple clients simultaneously?
- 802.11n
- 802.11ac Wave 1
- 802.11ac Wave 2 (Correct answer)
- 802.11ax
Correct answer: 802.11ac Wave 2
802.11ac Wave 2 introduced downlink MU-MIMO, allowing APs to transmit to multiple clients simultaneously rather than sequentially.
Question 4: In Aruba Instant (IAP) deployments, which AP automatically becomes the Virtual Controller?
- The AP with the highest MAC address
- The AP with the lowest IP address
- The AP elected based on longest uptime and highest IP (Correct answer)
- The AP manually designated by the administrator
Correct answer: The AP elected based on longest uptime and highest IP
The IAP Virtual Controller election uses uptime first, then highest IP address as a tiebreaker, to select which AP manages the cluster.
Question 5: What is the function of the Aruba ClientMatch feature?
- It matches client certificates to ClearPass profiles
- It steers clients to the best AP based on real-time RF conditions (Correct answer)
- It maps client VLANs to roles
- It detects rogue clients on the network
Correct answer: It steers clients to the best AP based on real-time RF conditions
ClientMatch continuously monitors client RF statistics and steers sticky clients to better APs, improving load balancing and user experience.
Question 6: Which Aruba deployment model uses Aruba Central as the sole management plane with no on-premises controller?
- Controller-based
- Instant (IAP)
- Cloud-managed with Aruba Central (Correct answer)
- Hybrid controller mode
Correct answer: Cloud-managed with Aruba Central
Cloud-managed deployments use Aruba Central for configuration, monitoring, and policy management without requiring an on-premises Mobility Controller.
Question 7: What is the maximum number of SSIDs that Aruba recommends broadcasting on a single AP for optimal performance?
- 2
- 4 (Correct answer)
- 8
- 16
Correct answer: 4
Aruba recommends a maximum of 4 SSIDs per AP, as each additional SSID increases beacon overhead and reduces available airtime for client traffic.
