HPE2Z40 Delta Applying Aruba Switching Fundamentals for Mobility Free Practice Test — 30 Questions

Question 1

Upon integrating a significant number of new IoT sensors across an enterprise campus network, an Aruba switching administrator observes a marked increase in inter-VLAN routing delays and intermittent packet loss affecting critical business applications. Initial troubleshooting suggests the new devices are not inherently faulty but are contributing to unforeseen network congestion patterns. Which approach best demonstrates the required behavioral competencies and technical acumen to address this evolving situation effectively?

Accepted Answer

Implement a phased diagnostic strategy, starting with traffic analysis and QoS adjustments for the new IoT traffic, while maintaining open communication with stakeholders regarding ongoing investigation and potential interim workarounds.

Question 2

Anya, a network engineer implementing Aruba CX switching fundamentals, is responsible for a new deployment featuring an Aruba CX 8325 core switch. She needs to enforce strict network segmentation between a dedicated Internet of Things (IoT) device management network (VLAN 100) and the primary corporate LAN (VLAN 10). The critical requirement is to prevent any IoT devices from initiating connections or sending traffic towards any host or server within the corporate LAN. However, authorized personnel on the corporate network must retain the ability to initiate management sessions to the IoT devices. What is the most appropriate and secure configuration step to achieve this specific traffic control requirement at the core switch?

Accepted Answer

Apply an inbound Layer 3 Access Control List (ACL) on the VLAN 100 interface that denies all traffic destined for the VLAN 10 subnet.

Question 3

Consider a scenario where a network administrator, responsible for a critical Aruba-based campus network supporting diverse services, is tasked with immediately implementing a new, stringent Quality of Service (QoS) policy for an emergent, high-priority client application. This application demands guaranteed bandwidth for real-time voice and video streams, with strict latency limitations.

Question 4

Consider a corporate network environment utilizing Aruba\'s Dynamic Segmentation technology. An employee, initially authenticated with a standard \"guest\" role upon connecting to a wireless access point, attempts to access a sensitive internal server designated for confidential project data. The network policy is configured such that the \"guest\" role explicitly denies access to this server\'s IP address range and associated ports, while an \"employee\" role permits it. Which of the following sequences of events most accurately describes the necessary steps for the employee to successfully access the confidential server after an initial denial?

Accepted Answer

The user's credentials are re-evaluated, leading to a role reassignment from "guest" to "employee" by the Mobility Controller, which then updates the Policy Enforcement Firewall rules to permit access to the confidential server.

Question 5

A large enterprise campus network, leveraging Aruba CX switches for its mobility infrastructure, is experiencing widespread, intermittent connectivity disruptions. Users report dropped sessions and slow application performance, particularly when mobile devices roam between access points.
