Question 1

In an ArubaOS 10 architecture using an AP and a gateway, what happens when a client attempts to join the network and the WLAN is configured with OWE?



Answer : A

This is the correct statement about what happens when a client attempts to join the network and the WLAN is configured with OWE (Opportunistic Wireless Encryption). OWE is a standard that provides encryption for open networks without requiring any authentication or credentials from the client or the network. OWE uses a Diffie-Hellman key exchange mechanism to establish a secure session between the client and the AP without exchanging any authentication information. The other options are incorrect because they either describe scenarios that require authentication or encryption methods that are not used by OWE.

Question 2

You need to create a keepalive network between two Aruba CX 8325 switches for VSX configuration How should you establish the keepalive connection?



Answer : B

To establish a keepalive connection between two Aruba CX 8325 switches for VSX configuration, you need to use a routed port in custom VRF. A routed port is a physical port that acts as a layer 3 interface and does not belong to any VLAN. A custom VRF is a virtual routing and forwarding instance that provides logical separation of routing tables. By using a routed port in custom VRF, you can isolate the keepalive traffic from other traffic and prevent routing loops or conflicts. The other options are incorrect because they either do not use a routed port or do not use a custom VRF.

Question 3

Your customer has asked you to assign a switch management role for a new user The customer requires the user role to only have Web Ul access to the System > Log page and only have access to the GET method for REST API for the /logs/event resource

Which default AOS-CX user role meets these requirements?



Answer : A

The auditors role is the default AOS-CX user role that meets the requirements of having Web UI access to the System > Log page and having access to the GET method for REST API for the /logs/event resource. The auditors role has a level of 1 and allows read-only access to most commands except those related to security or passwords. It also allows access to the Web UI and REST API with limited permissions. The other options are incorrect because they either have higher levels of access or do not allow access to the Web UI or REST API.

Question 4

A customer with a large installed base of HPE Aruba Networking AP-315, AP-335, and AP-515 is concerned about power consumption at night when almost nobody is working.

Which changes are needed to optimize this environment? (Select two.)



Answer : A, D

The required optimization is to use IEEE 802.3az Energy Efficient Ethernet (EEE) across the AP deployment. Aruba documentation states that 802.3az allows supported APs to consume less power during periods of low data activity, which directly matches the scenario of reducing nighttime energy consumption. Aruba Networking

However, Aruba explicitly documents that 802.3az is not supported on the AP-315 or the 330 Series, which includes the AP-335. Aruba Networking Consequently, those older AP-315 and AP-335 units must be replaced with models supporting EEE. The AP-515 belongs to a newer generation and does not fall within Aruba's documented EEE exclusions, so replacing the AP-515 is unnecessary.

After installing EEE-capable replacements, 802.3az should be enabled across the AP environment, allowing Ethernet links to reduce power usage during low-traffic periods.

IPM is not the primary mechanism for this requirement. Aruba describes Intelligent Power Monitoring as dynamically restricting AP functions when AP consumption approaches or exceeds its available power budget. It is primarily concerned with operating an AP within available PoE resources, rather than automatically exploiting nighttime Ethernet inactivity. Aruba Networking


Question 5

A visitor establishes an authenticated wireless connection at your office that leverages an HPE Aruba Networking ClearPass Policy Manager server for all authorization.

Which component below will disconnect the user and require re-authorization when the visitor goes past their allowed duration?



Answer : B

The correct mechanism is RADIUS Change of Authorization (CoA). ClearPass Policy Manager can dynamically alter or terminate an already authenticated network session by sending a RADIUS dynamic-authorization message to the network access device. Aruba defines dynamic authorization as the capability to modify a user's authorization while the session is active, including disconnecting the session. Aruba Networking

For guest accounts, ClearPass can associate an expiration time or permitted access duration with the account. When the configured expiration condition requires the guest to be logged out, ClearPass can issue a RADIUS Disconnect-Request to the NAS, such as an Aruba wireless controller or access infrastructure. Aruba's ClearPass Guest documentation specifically describes the Disable and logout behavior as disabling further authorization and using a RADIUS Disconnect-Request for matching active sessions. Aruba Networking Once disconnected, the client must go through the applicable authentication and authorization process again before network access can resume.

An Authorization Profile defines what access should be granted but does not itself provide the dynamic session-disconnect mechanism. Active Directory session timeout and Wi-Fi Sense do not fulfill this ClearPass enforcement function.


Question 6

When setting up an AOS-CX VSX pair, which information does the Inter-Switch Link Protocol synchronize in the configuration created?



Answer : D

The Inter-Switch Link (ISL) is a fundamental component of an AOS-CX Virtual Switching Extension (VSX) pair. It serves both as a Layer 2 forwarding path between the VSX peers and as the principal control-path channel used to synchronize operational state between the two switches.

HPE Aruba Networking explicitly identifies the MAC table as one of the data structures synchronized across the VSX ISL. Other synchronized information includes the ARP table, LACP state for VSX LAGs, and MSTP state. This synchronization enables both independent VSX switches to maintain consistent forwarding information and support resilient multi-chassis LAG operation. Aruba Networking

The architecture is important because VSX does not merge both switches into a single control plane. Each peer retains its own control plane, while selected operational databases and protocol states are synchronized through the ISL. HPE's Campus Design guidance similarly states that VSX peers synchronize MAC, ARP, STP, and other state tables across the ISL. Aruba Networking

An SVI is configuration rather than the requested synchronized forwarding-table information. UDLD is a link-detection protocol, and RPVST+ is not the answer identified in Aruba's ISL synchronization list.


Question 7

You are doing tests in your lab and with the following equipment specifications

* AP1 has a radio that generates a 10 dBm signal

* AP2 has a radio that generates a 11 dBm signal

* AP1 has an antenna with a gain of 9 dBi

* AP2 has an antenna with a gain of 12 dBi.

* The antenna cable for AP1 has a 2 dB loss

* The antenna cable for AP2 has a 3 dB loss

What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for APT?



Answer : C

The calculated Equivalent Isotropic Radiated Power (EIRP) for AP1 is 17 dBm.

EIRP is the measured radiated power of an antenna in a specific direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It can also take into account the losses in transmission line, connectors, and other components. The formula for EIRP is:

EIRP = P + G - L

where P is the output power of the radio, G is the gain of the antenna, and L is the loss of the cable and connectors.

For AP1, we have:

P = 10 dBm G = 9 dBi L = 2 dB

Therefore,

EIRP = 10 + 9 - 2 EIRP = 17 dBm
