1. Manual text-based routing table generators.
2. Automated power grid load balancers.
3. Floor Plan VisualRF and Location Services.
4. Local print queue monitoring dashboards.

Correct Answer: 3

Explanation:

Aruba Central incorporates powerful location-based mapping tools, such as VisualRF, which enable administrators to upload facility floor plans, place access points at exact physical coordinates, and visualize real-time wireless coverage heatmaps. This capability assists IT teams in identifying potential dead zones, analyzing client density distributions, tracking asset locations, and optimizing overall radio frequency coverage across complex enterprise buildings without requiring separate on-premises management software.

Question 163

How does Aruba ClearPass handle profiling of connected endpoints to enforce accurate network access policies?

1. By asking users to type their device serial numbers into a chat window daily.
2. By blocking all unknown devices permanently from sending email messages.
3. By forcing every device to run a heavy antivirus scan before obtaining an IP address.
4. By collecting DHCP, HTTP user-agent, MAC OUI, and SNMP data to identify device types automatically.

Correct Answer: 4

Explanation:

Aruba ClearPass Profiler continuously gathers diverse telemetry data—such as DHCP fingerprints, HTTP user-agent strings, MAC OUI vendor codes, and SNMP responses—from endpoints as they connect to the network. By analyzing these attributes, ClearPass accurately identifies the device type, operating system, and manufacturer. This automated profiling enables dynamic role assignment, ensuring that each endpoint receives precisely tailored access privileges according to corporate security guidelines.

Question 164

What is the primary benefit of deploying Aruba CX Mobile App for field technicians during initial deployments?

1. It streamlines switch installation, firmware upgrades, and configuration via Bluetooth or serial connection.
2. It allows technicians to stream movies while waiting for hardware to boot.
3. It automatically pays field technicians their hourly wages upon task completion.
4. It replaces the need for physical Ethernet cabling entirely.

Correct Answer: 1

Explanation:

The Aruba CX Mobile App empowers field technicians to deploy, configure, and manage Aruba CX switches efficiently right from their mobile devices. By connecting securely via Bluetooth Low Energy or serial console cables, technicians can perform initial configurations, apply firmware updates, check operational status, and verify port connectivity rapidly. This mobile-first approach eliminates the need to carry bulky laptops into wiring closets, accelerating deployment times and reducing human configuration errors.

Question 165

Which technology enables seamless Layer 2 roaming across different subnets in an Aruba controller-based architecture?

1. Static ARP caching on end-user computers.
2. Mobility tunnels established between mobility controllers.
3. Disabling all wireless encryption standards.
4. Forcing users to re-authenticate every time they walk into a new hallway.

Correct Answer: 2

Explanation:

In Aruba controller-based wireless environments, mobility tunnels between mobility controllers enable seamless Layer 2 roaming across different physical subnets. When a client roams from an access point managed by one controller to an AP managed by another controller on a different subnet, the client’s original IP address and session state are preserved through a secure mobility tunnel. This ensures uninterrupted application performance and eliminates dropped connections for mobile users roaming throughout a campus.

Question 166

What function does Aruba ClearPass On-Demand perform for contractor or temporary visitor access?

1. It permanently upgrades contractor laptops to full corporate domain administrator status.
2. It provides temporary, time-bound network access credentials with automated expiration rules.

4. It formats the hard drives of all non-employee devices upon connection.

Correct Answer: 2

Explanation:

Aruba ClearPass provides flexible guest and contractor management capabilities that issue time-bound network credentials with strict expiration policies. Temporary users or contractors can self-register or receive credentials via sponsors, gaining restricted access to the internet or designated resources. Once the pre-configured time window expires, ClearPass automatically revokes their network access, maintaining rigorous perimeter security without creating permanent administrative overhead for IT departments.

Question 167

How does Aruba SD-Branch maintain branch office security without requiring dedicated physical firewalls at every location?

1. By turning off all internet access for branch workers.

2. Remote Authentication Dial-In User Service (RADIUS).
3. Simple Mail Transfer Protocol (SMTP).
4. File Transfer Protocol (FTP).

Correct Answer: 2

Explanation:

Aruba ClearPass relies on the Remote Authentication Dial-In User Service protocol to handle authentication, authorization, and accounting functions across enterprise networks. When devices connect, RADIUS communicates user credentials and authorization roles between the network access device and ClearPass, while also tracking accounting sessions to monitor network usage duration and data transfer statistics for auditing and compliance purposes.

Question 173

How does Aruba Dynamic Segmentation benefit network administrators managing multi-vendor wired switches?

1. By forcing administrators to replace all non-Aruba switches immediately.
2. By disabling all switch port security features permanently.
3. By requiring manual VLAN configuration on every individual switch port.
4. By tunneling traffic from third-party or Aruba switches to mobility gateways for consistent policy enforcement.

Correct Answer: 4

Explanation:

Aruba Dynamic Segmentation can extend unified role-based policy enforcement to various network environments by encapsulating wired user traffic into secure GRE tunnels directed toward Aruba mobility gateways or controllers. Once tunneled, traffic is subjected to stateful firewall inspection and role-based policies, allowing organizations to maintain consistent security enforcement across diverse infrastructure without complex configuration overhead.

Question 174

What is the primary objective of Aruba’s User Role enforcement in wireless and wired architectures?

1. Restricting all users to identical, highly limited network access privileges.
2. Forcing users to remember separate passwords for every room in a building.
3. Dynamically assigning network access permissions and firewall policies based on user identity and device context.
4. Preventing any user from connecting more than one device to the network.

Correct Answer: 3

Explanation:

Aruba User Role enforcement allows network administrators to define granular security policies associated with specific user roles. Instead of relying on static VLAN memberships, the network dynamically assigns appropriate access permissions, bandwidth limits, and firewall rules based on who the user is and what device they are using, ensuring precise security posture enforcement across the entire enterprise.

Question 175

Question 176

How do Aruba Instant Access Points handle software and firmware updates across a cluster?

1. Technicians must manually plug a USB flash drive into every single access point in the building.
2. Access points delete their operating systems and refuse to reconnect to the network.
3. Firmware updates are strictly forbidden to prevent network instability.
4. The virtual controller downloads the firmware image and automatically distributes it to all member APs for synchronized rolling upgrades.

Correct Answer: 4

Explanation:

Aruba Instant Access Points simplify software maintenance through an automated rolling upgrade process managed by the virtual controller. When a new firmware version is released, the virtual controller downloads the image and coordinates the upgrade across cluster members sequentially or simultaneously. This ensures minimal network disruption, maintains continuous client connectivity, and eliminates the need for manual, device-by-device firmware updates.
