ACMA Access Point Deployment 4 — Questions and Answers
Question 1: Which Aruba AP operational mode forwards client traffic directly to the local network without passing through the controller?
- Tunnel mode
- Decrypt-tunnel mode
- Bridge mode (Correct answer)
- Split-tunnel mode
Correct answer: Bridge mode
In bridge mode, client traffic is bridged directly to the local VLAN without being encapsulated and sent to the controller.
Question 2: What is the significance of the AP group 'default' in Aruba controller configuration?
- It is reserved for mesh APs only
- APs that do not match any other AP group are placed here (Correct answer)
- It contains the highest-priority radio profiles
- It is the group used for remote APs (RAPs) exclusively
Correct answer: APs that do not match any other AP group are placed here
The 'default' AP group serves as a catch-all; any AP that doesn't match a specific AP group assignment is placed in this group.
Question 3: Which factor most directly determines whether an Aruba AP can operate as a Remote AP (RAP) across the internet?
- The AP must support 802.11ac Wave 2
- A valid IPsec tunnel must be established to the controller (Correct answer)
- The AP must be within 100ms round-trip latency of the controller
- The RAP must use a static public IP address
Correct answer: A valid IPsec tunnel must be established to the controller
Remote APs require an IPsec tunnel back to the Mobility Controller to authenticate and receive configuration over the internet.
Question 4: During an Aruba AP site survey, what is the recommended minimum RSSI threshold for voice-grade wireless coverage?
- -85 dBm
- -75 dBm
- -67 dBm (Correct answer)
- -55 dBm
Correct answer: -67 dBm
-67 dBm is the commonly accepted minimum RSSI for voice-grade wireless coverage to ensure sufficient SNR for low-latency, low-loss communication.
Question 5: What Aruba feature prevents a newly deployed AP from broadcasting SSIDs until it has received its full configuration from the controller?
- AP whitelist enforcement (Correct answer)
- Zero-touch provisioning hold
- Supervised AP bootstrapping
- Configuration commit lock
Correct answer: AP whitelist enforcement
The AP whitelist requires APs to be pre-approved before they can receive configuration and begin serving clients.
Question 6: An administrator wants to deploy Aruba APs across multiple buildings managed by a single controller cluster. Which feature enables APs in different buildings to roam clients seamlessly?
- Layer 2 mobility domain
- Aruba Mobility Master redundancy group
- RF domain with a shared mobility controller (Correct answer)
- Mesh backhaul bridge group
Correct answer: RF domain with a shared mobility controller
A shared RF domain across controllers allows seamless client roaming by coordinating authentication state and IP addressing.
Question 7: Which Aruba AP LED pattern typically indicates that the AP has established a connection to the controller and is operating normally?
- Alternating red and green
- Solid green (Correct answer)
- Slow amber blink
- Rapid blue flash
Correct answer: Solid green
A solid green LED on most Aruba APs indicates the AP has successfully connected to the controller and is serving clients.
